Changelog

This project adheres to Semantic Versioning and human-readable changelog.

This file contains only general overview of the changes in the DebOps project. The detailed changelog can be seen using :command:`git log` command.

You can read information about required changes between releases in the :ref:`upgrade_notes` documentation.

debops master - unreleased

Added

New DebOps roles

  • The :ref:`debops.extrepo` role provides an interface for the extrepo Debian package, an external APT source manager. It can be used to configure third-party APT repositories.
  • The :ref:`debops.sssd` role can be used to manage the System Security Services Daemon (sssd), an alternative approach to centralized credentials managed by remote databases like LDAP or Active Directory.

General

:ref:`debops.netbox` role

Changed

Updates of upstream application versions

  • In the :ref:`debops.ipxe` role, the Debian Buster netboot installer version has been updated to the next point release, 10.8.
  • In the :ref:`debops.roundcube` role, the Roundcube version installed by default has been updated to 1.4.11.

Continuous Integration

  • The Vagrant provisioning script now installs Cryptography from the Debian archive instead of from PyPI.

:ref:`debops.roundcube` role

  • The address autocompletion will show only a specific e-mail address instead of all available ones for a given recipient.
  • The role will configure Roundcube to search the LDAP directory for a given user's Distinguished Name when their LDAP entry uses a different attribute than uid as RDN. Directory will be searched using the Roundcube's own login credentials. See :ref:`roundcube__ref_ldap_dit` for details.
  • The new_user_identity plugin will be re-enabled by default and adjusted to use the mail attribute to search for user identities. Roundcube v1.4.x installations might need to be patched for the plugin to work correctly with user-based LDAP logins.

Changes to DebOps Enhancement Proposals

  • DEP 3 - Sources of software used by DebOps now requires for roles that configure upstream APT repositories to use debops.extrepo instead of the previously used way of including the OpenPGP fingerprint and repo details in the role. This applies to all new roles. Existing roles will be updated over time.

Fixed

General

:ref:`debops.apt` role

  • The role configured the Debian Bullseye security repository with the 'bullseye/updates' suite name. This is incorrect, the Bullseye security suite is called 'bullseye-security'.

:ref:`debops.cron` role

:ref:`debops.etesync` role

  • The EteSync playbook is now included in the default DebOps playbook.

:ref:`debops.iscsi` role

  • Fixed a typo that caused the iSCSI target discovery task to fail.

:ref:`debops.netbox` role

  • NetBox crashed when it tried to send Emails. For example when an exception occured during page loading, the reponse was just "Internal Server Error". The service as a whole survives this. The bug in the configuration template has been fixed.

:ref:`debops.sudo` role

  • The role no longer adds a duplicate includedir line to /etc/sudoers. This was an issue with sudo 1.9.1 (and later), which changed the includedir syntax from '#includedir' to '@includedir'.

:ref:`debops.system_users` role

  • Use the Python version detected on the Ansible Controller instead of the remote host to run the UNIX account fact gathering script.

debops v2.2.0 - 2021-01-31

Added

New DebOps roles

  • The :ref:`debops.dhcrelay` role can be used to manage the ISC DHCP Relay Agent, which forwards DHCP traffic between networks. This role replaces the dhcrelay functionality in :ref:`debops.dhcpd`.
  • The :ref:`debops.global_handlers` Ansible role provides a central place to maintain handlers for other Ansible roles. Keeping them centralized allows Ansible roles to use handlers from different roles without including them entirely in the playbook.
  • The :ref:`debops.filebeat` role can be used to install and configure Filebeat, a log shipping agent from Elastic, part of the Elastic Stack.

General

  • The :file:`tools/reboot.yml` can be used to reboot DebOps hosts even if they are secured by the molly-guard package.
  • The code in the DebOps monorepo is now checked using GitHub Actions, which will replace Travis-CI. Thank you, Travis, for years of service. :)

LDAP

  • The :ref:`next available UID and GID values <ldap__ref_next_uid_gid>` can now be tracked using special LDAP objects in the directory. These can be used by the client-side account and group management applications to easily allocate unique UID/GID numbers for newly created accounts and groups.

    The objects will be created automatically with the next available UID/GID values by the :file:`ldap/init-directory.yml` playbook. In existing environments users might want to create them manually to ensure that the correct uidNumber and gidNumber values are stored instead of the default ones which might already be allocated.

  • The root UNIX account will now have full write access to the main directory via the ldapi:// external authentication and can create and modify the LDAP objects and their attributes. This is required so that the :ref:`debops.slapd` role can initialize the directory tree and create/remove the ACL test objects as needed.

:ref:`debops.apt` role

  • The role facts now include the main APT architecture (amd64, for example) and a list of foreign architectures if any are enabled. The ansible_local.apt.architecture fact can be used in other roles that need that information.

:ref:`debops.apt_install` role

  • The role now installs CPU microcode packages on physical hosts by default. These firmware updates correct CPU behaviour and mitigate vulnerabilities like Spectre and Meltdown. You still need to take measures to protect your virtual machines; for this, take a look at the QEMU documentation.

:ref:`debops.icinga` role

  • The role can now create Icinga configuration on the Icinga "master" node via task delegation. This can be useful in centralized environments without Icinga Director support.

:ref:`debops.lvm` role

  • Default LVM2 configuration for Debian Stretch and Buster has been added.

:ref:`debops.owncloud` role

  • Drop Nextcloud 16, 17 and 18 support because it is EOL. You need to upgrade Nextcloud manually if you are running version 18 or below. The role now defaults to Nextcloud 19 for new installations.

:ref:`debops.postgresql` role

  • The role can now drop PostgreSQL databases and remove roles when their state is set to absent in the Ansible inventory.

:ref:`debops.resources` role

  • Support manipulating file privileges using the Linux :manpage:`capabilities(7)` with the help of the Ansible capabilities module.

:ref:`debops.roundcube` role

  • The role will enable more plugins by default: help, markasjunk, password (only with LDAP).
  • Roundcube will offer local spell checking support by default with Enchant library. English language is supported by default, more languages can be added via Ansible inventory.

:ref:`debops.slapd` role

  • Support for the dynamic LDAP groups maintained by the :ref:`slapd__ref_autogroup_overlay` has been implemented in the role. Debian Buster or newer is recommended for this feature to work properly.
  • A set of FreeRADIUS LDAP schema has been added to the role. RADIUS Profiles, Clients and FreeRADIUS DHCP configuration can be stored in the LDAP directory managed by DebOps and used by the :ref:`debops.freeradius` Ansible role.
  • Support for empty LDAP groups has been added via the :ref:`groupfentries schema <slapd__ref_groupofentries>` with a corresponding memberOf overlay. This change changes the order of existing overlays in the LDAP database which means that the directory server will have to be rebuilt.
  • New :ref:`orgstructure schema <slapd__ref_orgstructure_schema>` provides the organizationalStructure LDAP object class which is used to define the base directory objects, such as ou=People, ou=Groups, etc.
  • Members of the cn=LDAP Administrator LDAP role can now manage the server configuration stored in the cn=config LDAP subtree.

:ref:`debops.sysctl` role

  • The role can now be enabled or disabled conditionally via Ansible inventory. This might be required in certain cases, for example LXD containers or systems protected with AppArmor rules, which make the :file:`/proc/sys/` directory read-only.

Changed

Updates of upstream application versions

  • In the :ref:`debops.ipxe` role, the Debian Stretch and Debian Buster netboot installer versions have been updated to their next point releases, 9.13 and 10.7 respectively.
  • In the :ref:`debops.roundcube` role, the Roundcube version installed by default has been updated to 1.4.10.
  • In the :ref:`debops.owncloud` role, the Nextcloud version installed by default has been updated to v18.0.
  • In the :ref:`debops.phpipam` role, the phpIPAM version installed by default has been updated to v1.4.1.
  • In the :ref:`debops.netbox` role, the NetBox version has been updated to v2.10.3. The plugin support added in v2.8.0 can be configured from DebOps. The NetBox Request Queue Worker service is configured to support background jobs like reports to work.
  • The :ref:`debops.mariadb` and :ref:`debops.mariadb_server` roles now support installation of Percona Server/Client v8.0 from upstream APT repositories.

General

  • The debops.debops role has been renamed to the :ref:`debops.controller` role to allow for the debops__ variable namespace to be used for global variables. All role variables have been renamed along with the role inventory group, you will have to update your inventory.
  • Most of the handers from different DebOps roles have been moved to the new :ref:`debops.global_handlers` role to allow for easier cross-role handler notification. The role has been imported in roles that rely on the handlers.
  • The debops-contrib.* roles included in the DebOps monorepo have been renamed to drop the prefix. This is enforced by the new release of the :command:`ansible-lint` linter. These roles are not yet cleaned up and integrated with the main playbook.
  • The dependency on pyOpenSSL has been removed. This dependency was required in Ansible < 2.8.0 because these versions were unable to use the cryptography module, but DebOps is nowadays developed against Ansible 2.9. pyOpenSSL was used only to generate private RSA keys for the :ref:`debops.opendkim` role. Switching to cryptography is also a security precaution and the Python Cryptographic Authority recommends doing so.

LDAP

:ref:`debops.core` role

  • The fact script will generate the list of private e-mail addresses used to send administrative mail notifications based on the list of admin accounts and the detected domain of the host; this can be overriden via the :envvar:`core__admin_private_email` variable. The change is done to avoid sending mail messages to 'account-only' addresses on hosts without local mail support.

:ref:`debops.dhcpd` role

  • The debops.dhcpd role has been largely rewritten in order to support both IPv4 and IPv6 on the same server, and to modernize many aspects of the role.
  • The DHCP Relay Agent functionality has been moved to :ref:`debops.dhcrelay`.

:ref:`debops.docker_server` role

  • The role's virtual environment is no longer created by default when :envvar:`docker_server__upstream` is False. This does not impact existing virtualenvs. You can remove /usr/local/lib/docker/virtualenv yourself if you like.

:ref:`debops.etckeeper` role

  • The role now installs etckeeper on all hosts by default, not just on hosts that have a Python 2 environment. etckeeper is also installed from buster-backports instead of the main Debian 10 repository.

:ref:`debops.fhs` role

  • The role will create the :file:`/srv/www/` directory by default to allow for home directories used by web applications.

:ref:`debops.gitlab` role

  • The :command:`systemd` services no longer require Redis to be installed on the same host as GitLab itself.
  • Improved support for GitLab Pages, including optional access control and fixed configuration of the :command:`systemd` service.

:ref:`debops.grub` role

  • The role will now activate both the serial console and the (previously disabled) native platform console when grub__serial_console is True.

:ref:`debops.icinga_web` role

  • The role now automatically configures LDAP user and group support.
  • The role will install and configure the Icinga Certificate Monitoring module.

:ref:`debops.lvm` role

  • Linux Software RAID devices are now scanned by default.

:ref:`debops.lxd` role

  • During installation, the role will enable trust for the GitHub's GPG signing key to allow for verification of the LXD source code. Check the :ref:`lxd__ref_install_details` for more information.

:ref:`debops.nginx` role

  • The default SSL configuration used by the role has been updated to bring it to the modern standards. By default only TLSv1.2 and TLSv1.3 protocols are enabled, along with an improved set of ciphers. The HTTP Strict Transport Security age has been increased from 6 months to 2 years. The configuration is based on the intermediate Mozilla SSL recommendations to support wide range of possible clients.
  • The server can be configured to support TLSv1.3 protocol only using the :envvar:`nginx_default_tls_protocols` variable, which will disable the use of custom Diffie-Hellman parameters and allow the HTTPS clients to select their own preferred ciphers to use for connections. The preferred set of ciphers will also change to Mozilla modern variant. Keep in mind that not all clients support this configuration.

:ref:`debops.postfix` role

  • Postfix :file:`main.cf` configuration overrides are now written to the :file:`master.cf` configuration file using 'long form' notation supported since Postfix 3.0. This allows specifying parameter values that contain whitespace.
  • The DSN command is now disabled by default. DSN (RFC 3464) gives senders control over successful and failed delivery status notifications. This allows spammers to learn about an organization's internal mail infrastructure, and gives them the ability to confirm that an address is in use. When DSN support is disabled, Postfix will still let the SMTP client know that their message has been received as part of the SMTP transaction; they just will not get successful delivery notices from your internal systems.
  • The ETRN command is now disabled by default. ETRN, also known as Remote Message Queue Starting (RFC 1985), was designed for sites that have intermittent Internet connectivity, but is rarely used nowadays.

:ref:`debops.resolvconf` role

  • The 'domain', 'nameservers' and 'search' variables have been removed from the resolvconf Ansible local facts script. You are encouraged to use the ansible_domain, ansible_dns.nameservers and ansible_dns.search variables instead.

:ref:`debops.slapd` role

  • The role will set up an additional instance of the memberof OpenLDAP overlay to update role membership in the organizationalRole LDAP objects. This change modifies the list of overlays and will require re-initialization of the OpenLDAP directory.

  • New equality indexes have been added to the :command:`slapd` service: roleOccupant, memberOf and employeeNumber.

  • The :file:`eduperson.schema` LDAP schema has been extended with additional attributes not present in the official specification. The new schema will not be applied automatically on existing installations.

  • In the OpenLDAP ACL rules, authenticated object owners can now re-authenticate themselves using the userPassword attribute. This is needed for the LDAP Password Modify Extended Operation (RFC 3062) to work correctly in Roundcube.

  • In the :file:`mailservice.schema` LDAP schema, the mailACLGroups attribute has been renamed to mailGroupACL since this seems to be the name used by different applications like Dovecot and Roundcube.

    This change will not be applied automatically in an existing LDAP directories - they will need to be rebuilt to apply new schema changes.

  • The role will install a modified :ref:`OpenSSH-LPK schema <slapd__ref_openssh_lpk>` instead of the version from the FusionDirectory project, to add support for storing SSH public key fingerprints in the LDAP directory. Existing installations shouldn't be affected.

  • The :command:`slapacl` test map with additional object RDNs has been redesigned into a list of test LDAP objects which can be created or removed by the role as needed. They will not be added to the directory by default and can be enabled via Ansible inventory.

  • The support for OpenLDAP monitoring is improved. The root UNIX account as well as members of the "LDAP Administrator" and "LDAP Monitor" roles can now read the cn=Monitor information.

Removed

:ref:`debops.ldap` role

  • Creation of various LDAP directory objects (ou=People, ou=Groups, ...) has been removed from the default list of LDAP tasks performed by the role. These objects are now automatically created by the :ref:`debops.slapd` role. The :ref:`debops.ldap` role will still ensure that all LDAP objects needed to maintain the hosts' directory information are present.

Fixed

General

LDAP

  • The :file:`ldap/init-directory.yml` playbook will correctly initialize the LDAP directory when the local UNIX account does not have any GECOS information.

:ref:`debops.apt` role

  • Fixed an issue where the role would attempt to add APT keys from a PGP keyserver without installing the :command:`gnupg` package first.

:ref:`debops.dokuwiki` role

  • A few custom DokuWiki plugins will be removed if installed, otherwise they will not be installed anymore due to issues with newest DokuWiki release. Affected plugins: advrack, rst, gitlab, ghissues.
  • Ensure that the authldap DokuWiki plugin is enabled when LDAP support is configured by the role.

:ref:`debops.etherpad` role

  • Fixed the installation of Etherpad with the PostgreSQL backend by removing unused dependent variables.

:ref:`debops.fail2ban` role

  • Fixed the configuration support on Ubuntu Focal due to bantime feature changes in the :command:`fail2ban` v0.11.

:ref:`debops.fcgiwrap` role

  • The role can now be used in check mode without throwing an AnsibleFilterError.

:ref:`debops.gitlab` role

  • Fixed an issue where the git UNIX account was not added to the _sshusers local group when LDAP support was enabled on the host. This prevented the usage of GitLab via SSH.

:ref:`debops.ifupdown` role

  • Network configuration with bonded interfaces should now be correctly applied by the reconfiguration script.

:ref:`debops.iscsi` role

  • Fixed uninitialized local fact ansible_local.iscsi.discovered_portals.

:ref:`debops.ldap` role

  • Fixed multiple issues with adding and updating hosts to the LDAP directory when these hosts were configured for network bonding.

:ref:`debops.lvm` role

  • Fixed an issue where the role would fail in check mode. The role tries to simulate creating a filesystem, but this failed when the underlying LVM volume did not actually exist (which is to be expected when running in check mode).
  • Made default behaviour match the documentation: the role now automatically takes care of mounting a filesystem on an LVM volume if the mount point is specified with item.mount. This previously required setting the item.fs parameter to True as well.

:ref:`debops.nginx` role

  • Disabled gzip compression of text/vcard MIME types. Vcards contain, by nature, sensitive information and should not be gzipped to prevent successful BREACH attacks.

:ref:`debops.netbox` role

  • Fixed initial superuser account creation.

:ref:`debops.nslcd` role

  • Enabled idle_timelimit to make sure that connections to the LDAP server are properly closed. A disabled or too high idle_timelimit causes the LDAP server to time out, resulting in nslcd errors like "ldap_result() failed: Can't contact LDAP server".

:ref:`debops.nfs` role

  • Ensure that with default mount options disabled, options specified by the user still are added in the configuration.

:ref:`debops.ntp` role

  • Don't try to disable or stop the systemd-timesyncd service when using an alternative NTP service implementation and systemd-timesyncd is not available.

:ref:`debops.owncloud` role

  • Fixed multiple issues which caused dry runs of the :ref:`debops.owncloud` role to incorrectly show pending changes or fail altogether.

:ref:`debops.php` role

  • Set correct APT preferences for the Backports or Sury APT repository to the libapache2-mod-php* APT packages to ensure that the selected repository is the same as the php* APT packages.

:ref:`debops.pki` role

  • The :command:`acme-tiny` script will be installed from Debian/Ubuntu repositories on Debian Buster, Ubuntu Focal and newer OS releases. This solves the issue with acme-tiny script in upstream having #!/usr/bin/env python shebang hard-coded which makes the script unusable on hosts without Python 2.7 installed.

    The installation location of the script from upstream is changed from :file:`/usr/local/lib/pki/` to :file:`/usr/local/bin/` to leverage the $PATH variable so that the OS version is used without issues. The script is now also symlinked into place instead of copied over.

:ref:`debops.postgresql_server` role

  • Rename the wal_keep_segments PostgreSQL configuration option to wal_keep_size on PostgreSQL 13 and later to avoid issues with starting the database service. You might need to update the inventory configuration if you use this parameter.
  • Fixed an issue with the role always reporting "changed" state due to postgresql_privs Ansible module not detecting changes in the PUBLIC PostgreSQL role.

:ref:`debops.python` role

  • The python-pip APT package will be installed only on older OS releases, since it has been removed from newer OS releases like Debian Bullseye and Ubuntu Focal.

:ref:`debops.rsnapshot` role

:ref:`debops.rsyslog` role

:ref:`debops.saslauthd` role

  • Fixed SMTP AUTH e-mail authentication for satellite hosts. Mail messages sent by :command:`nullmailer` and authenticated using LDAP should now be accepted by the SMTP server.

:ref:`debops.slapd` role

  • Modify the :file:`mailservice.schema` LDAP schema so that various mail-related attributes do not use the mail attribute as SUPerior attribute. This fixes an issue where searching for mail attribute values returned entries with the values present in related attributes, for example mailForwardTo, causing problems with account lookups.

    This change will require the rebuild of the OpenLDAP directory to be applied correctly. The role will not apply the changes on existing installations automatically due to the :file:`mailservice.schema` being loaded into the database.

  • The :command:`slapd-snapshot` script will now correctly create database snapshots when the cn=Monitor database is disabled or not configured.

:ref:`debops.snmpd` role

  • Don't create or modify the home directory of the :command:`snmpd` UNIX account to avoid issues on Ubuntu 20.04.

:ref:`debops.system_users` role

  • Fixed an issue where the role execution broke if the :envvar:`system_users__self_name` variable was set to an UNIX account which does not exist on the Ansible Controller, for example ansible. The role will now correctly create such UNIX accounts on the remote hosts with default GECOS and shell values.

:ref:`debops.tinc` role

  • Fix issue with Tinc VPN interfaces starting before the general host networking is set up and failing to bind to the selected bridge interface. The Tinc :command:`systemd` service will wait for the network-online.target unit to start up before activation.
  • Fixed an issue with the role where setting :envvar:`tinc__modprobe` variable to False did not turn off support for loading required kernel modules.

debops v2.1.0 - 2020-06-21

Added

New DebOps roles

  • The :ref:`debops.etesync` role allows to setup a EteSync server. EteSync is a cross-platform project to provide secure, end-to-end encrypted, and privacy respecting sync for your contacts, calendars and tasks.

:ref:`debops.pki` role

  • The role can now instruct acme-tiny to register an ACME account with one or more contact URLs. Let's Encrypt for example uses this information to notify you about expiring certificates and emergency revocation.
  • The :ref:`debops.dovecot` and :ref:`debops.postfix` roles now include the PKI hook scripts which will reload their corresponding services when the X.509 certificates used by them are changed.

:ref:`debops.postconf` role

  • The additional Postfix configuration managed by the role can now be added or removed conditionally, controlled by the :envvar:`postconf__deploy_state` variable.

:ref:`debops.python` role

  • Introduce :envvar:`python__pip_version_check` which defaults to False to disable PIP update checks outside of the system package manager. Before, this was not configured by DebOps leaving it at PIP default which meant it would check for updates occasionally.

:ref:`debops.resources` role

  • Add support for the access_time and modification_time parameters of the Ansible file module to the role.

:ref:`debops.roundcube` role

  • The role can now be configured to install Roundcube from private or internal :command:`git` repositories that might contain additional modifications to the application code required by some organizations. See the :ref:`roundcube__ref_private_repo` section in the documentation for details.

Changed

Updates of upstream application versions

  • In the :ref:`debops.ipxe` role, the Debian Stretch and Debian Buster netboot installer versions have been updated to their next point releases, 9.11 and 10.4 respectively.

  • In the :ref:`debops.owncloud` role, the Nextcloud version installed by default has been updated to v17.0. The ownCloud version has been updated to v10.4.

  • In the :ref:`debops.roundcube` role, the Roundcube version installed by default has been updated to v1.4.4.

  • In the :ref:`debops.lxd` role, the LXD version installed by default has been changed to the stable-4.0 branch, which is a LTS release. The role uses a :command:`git` branch instead of a specific tagged release to bypass broken LXD build dependency which is not yet fixed in a tagged release.

  • In the :ref:`debops.gitlab` role, the GitLab release installed on Debian Buster and newer OS releases is updated to 12-10-stable.

    This release requires Golang packages from buster-backports APT repository, which will be installed by default via the :ref:`debops.golang` role. Existing installations need to upgrade the Golang packages before the playbook is applied.

  • In the :ref:`debops.ansible` role, Ansible 2.9.x from the buster-backports repository will be installed on Debian Buster by default, when backports are enabled.

  • The :ref:`debops.mailman` role has been redesigned and now installs and configures Mailman 3.x instead of Mailman 2.x. Read the :ref:`mailman__ref_mailman2_migration` guide and the rest of the :ref:`debops.mailman` documentation for details.

Continuous Integration

  • The Vagrant provisioning script will install Ansible from PyPI by default. The version included in the current Debian Stable (Buster) is too old for the DebOps playbooks and roles.

General

  • The DebOps Collection published on Ansible Galaxy has been split into multiple Collections due to the number of Ansible roles present in DebOps. The debops.debops collection will install additional debops.rolesXY collections automatically via collection dependencies. The playbooks have been updated to include new Collections.

  • The DebOps repository is now compliant with the REUSE Specification. The SPDX License Identifiers have been added to the files contained in the repository and a valid copyright and license information will be required to pass the test suite.

  • In new DebOps environments, Ansible will ignore any missing inventory groups using the host_pattern_mismatch parameter. This will disable the "Could not match supplied host pattern" warning message present in most of the playbooks included in DebOps. To disable this message in an existing environment, add in the :file:`.debops.cfg` configuration file:

    [ansible inventory]
    host_pattern_mismatch = ignore
  • The :command:`debops` script will now use the Ansible inventory path defined in the :file:`.debops.cfg` configuration file [ansible defaults] section instead of the static :file:`ansible/inventory/` path.

  • The variables in various DebOps roles that define filesystem paths have been switched from using the ansible_local.root.* Ansible local facts to the new ansible_local.fhs.* facts defined by the :ref:`debops.fhs` role. The new facts use the same base paths as the old ones; there should be no issues if the variables have not been modified through Ansible inventory.

    If you have redefined any core__root_* variables in the Ansible inventory to modify the filesystem paths used by DebOps roles, you will need to update the configuration. See the :ref:`debops.fhs` role documentation for details.

  • The use of ansible_local.core.fqdn and ansible_local.core.domain local facts in roles to define the host DNS domain and FQDN has been removed; the roles will use the ansible_fqdn and ansible_domain facts directly. This is due to issues with the :ref:`debops.core` local facts not updating when the host's domain is changed and causing the roles to use wrong domain names in configuration.

:ref:`debops.cran` role

  • The custom cran Ansible module used by the role has been moved to the :ref:`debops.ansible_plugins` role to allow it to be used via Ansible Collection system, which requires all plugins to be centralized.

:ref:`debops.etc_aliases` role

  • The custom filter plugin used by the role has been moved to the :ref:`debops.ansible_plugins` role to allow it to be used via Ansible Collection system, which requires all plugins to be centralized.

:ref:`debops.golang` role

  • On Debian Buster, Golang APT packages from the buster-backports APT repository will be preferred instead of their Buster version. This allows for installation of applications that depend on a newer Go runtime environment, like GitLab or MinIO.

:ref:`debops.lxd` role

  • The support for the LXC containers managed by the :ref:`debops.lxc` role will be applied on the host when the LXD is configured, due to the build dependency on the lxc APT package. In this case, the lxcbr0 network bridge will not be configured by default.

:ref:`debops.mosquitto` role

  • Update the role for Debian Buster. No need anymore to install Python packages outside of the system package management.

:ref:`debops.nginx` role

  • TLSv1.3 is now enabled by default for nginx version 1.13.0 and up.

:ref:`debops.nullmailer` role

  • The Nullmailer smtpd service can now listen on both IPv4 and IPv6 addresses. It listens on both loopback addresses by default, where it used to only listen on the IPv6 loopback address.

:ref:`debops.owncloud` role

  • Support has been added for Nextcloud 17.0 and 18.0.

:ref:`debops.pki` role

  • Use inventory_hostname variable instead of the ansible_fqdn variable in paths of the directories used to store data on Ansible Controller. This decouples the host FQDN and domain name from the certificate management tasks in the role.

    Note

    The role will try to recreate existing X.509 certificates making the playbook execution idempotent. Removing the PKI realms and recreating them will fix this issue.

:ref:`debops.postfix` role

  • The persistent configuration stored on the Ansible Controller has been refactored and does not use multiple separate tasks to handle the JSON files.

:ref:`debops.rsyslog` role

  • The role has been refreshed and uses the custom Ansible filter plugins to manage the :command:`rsyslog` configuration files. The default configuration was rearranged, the :file:`/etc/rsyslog.conf` configuration file has the default contents that come with the Debian package and can be configured by the role. The configuration model has been redesigned; any changes in the configuration of the role set in the Ansible inventory need to be reviewed before applying the new version.
  • The rsyslog APT package and its service can be cleanly removed from the host, either via the role or by uninstalling the package itself.

Removed

:ref:`debops.console` role

:ref:`debops.core` role

  • The ansible_local.uuid local fact and corresponding variables and tasks have been removed from the role. A replacement fact, ansible_machine_id is an Ansible built-in.
  • The ansible_local.init fact has been removed from the role. A native ansible_service_mgr Ansible fact is it's replacement.
  • The ansible_local.cap12s fact has been removed from the role. A native set of Ansible facts (ansible_system_capabilities, ansible_system_capabilities_enforced is be used as a replacement.
  • The :file:`root.fact` script, corresponding variables and documentation have been removed from the role. This functionality is now managed by the :ref:`debops.fhs` role.
  • The ansible_local.core.fqdn and ansible_local.core.domain local facts and their corresponding default variables have been removed from the role. In their place, ansible_fqdn and ansible_domain facts should be used instead.

:ref:`debops.ntp` role

:ref:`debops.nullmailer` role

Fixed

General

  • Fix an issue with Ansible Collections where roles used via the include_role Ansible module broke due to the split into multiple collections. All roles will now have the debops.debops collection included by default in the :file:`meta/main.yml` file to tell Ansible where to look for dependent roles.
  • Fix an issue with the collection creation script where the role files that contained multiple uses of a particular custom Ansible plugin, for example template_src or file_src, were modified multiple times by the script.

:ref:`debops.apt` role

  • Fix BeagleBoards detection with Debian 10 image. Tested with a BeagleBoards Black.

:ref:`debops.cron` role

  • Fix creation of empty environment variables in :command:`cron` configuration files managed by Ansible.

:ref:`debops.dnsmasq` role

:ref:`debops.ferm` role

:ref:`debops.gitlab_runner` role

  • Don't re-create removed :file:`/etc/machine-id` contents during Vagrant box creation. This should fix issues with IP addresses received from DHCP by the Vagrant machines.

    Warning

    This fix is applied using the :command:`patch` command on the files packaged by APT. Existing installations will have to be updated manually, alternatively the changes applied previously should be removed from the affected files before the role is applied. See the patch files in the role :file:`files/patches/` directory for more information.

  • The GitLab package repository signing key has been replaced with the new key that has been in use since 2020-04-06, allowing APT to update package lists again. See the GitLab.com blog for more information about this change.

:ref:`debops.minio` role

  • Fix an issue during installation of recent MinIO releases, where during an initial restart the MinIO service would switch into "safe mode" when a problem with configuration is detected; this would prevent the service to be restarted correctly. Now the service should be properly stopped by :command:`systemd` after a stop timeout.

:ref:`debops.netbase` role

  • Use short timeout for DNS queries performed by the Ansible local fact script, in case that the DNS infrastructure is not configured. This avoids 60s timeouts during Ansible fact gathering in such cases.

:ref:`debops.nginx` role

  • The role now always sets the HTTP Strict Transport Security header when it is enabled, regardless of the response code.

:ref:`debops.postgresql_server` role

:ref:`debops.roundcube` role

  • Use the Roundcube version from Ansible local facts instead of the one defined in role default variables to detect if a database migration is required after Roundcube :command:`git` repository is updated.

:ref:`debops.slapd` role

  • Move the Private Enterprise Number and LDAP namespace OIDs of the DebOps organization to a separate :file:`debops.schema` file to avoid duplicated OIDs in the cn=schema LDAP subtree.

    Existing installations might need to be recreated to avoid warnings about duplicate OIDs emitted during OpenLDAP operations.

debops v2.0.0 - 2020-01-30

Added

New DebOps roles

  • The :ref:`debops.lxd` role brings support for LXD on Debian hosts by building the Go binaries from source, without Snap installation.

General

  • The DebOps Python package now includes the debops.<role>(5) manual pages for most of the DebOps roles with details about role usage, variable definition and the like. The manual pages are based on the existing role documentation.
  • The DebOps project directories can now include the :file:`ansible/global-vars.yml` file which can be used to define :ref:`global Ansible variables <global_vars>` that can affect playbook initialization.

:ref:`debops.docker_registry` role

:ref:`debops.docker_server` role

  • Add docker_server__install_virtualenv setting to disable python virtualenv installation.

:ref:`debops.gitlab_runner` role

  • The role can now use DNS SRV resource records to find the GitLab API host address. Additionally, GitLab Runner token can be stored in the :file:`secret/` directory in a predetermined location to avoid exposing it via the Ansible inventory. See the role documentation for details.

:ref:`debops.icinga` role

  • The role now configures the Icinga REST API to also listen on IPv6 addresses. It is possible to change the listen address and port through the icinga__api_listen and icinga__api_port variables.

:ref:`debops.nslcd` role

  • The role will now use a LDAP host filter by default, to allow for easy control over what UNIX accounts and UNIX groups are present on which hosts using the host LDAP attribute.

:ref:`debops.postgresql_server` role

  • A given PostgreSQL server cluster can be configured to enable standby replication mode, and receive streaming replication data from a master PostgreSQL server. See role documentation for examples.
  • The :command:`autopostgresqlbackup` script can be configured to tell the :command:`pg_dump` command to compress the generated backup files on the fly instead of creating a separate .sql file and compressing it afterwards. This mode is currently disabled by default.

:ref:`debops.resolvconf` role

  • The role can now define static DNS configuration to be merged with other DNS data sources in the :file:`/etc/resolv.conf` configuration file.

:ref:`debops.roundcube` role

  • The Roundcube installation is now more integrated with the DebOps environment. The role will automatically configure :ref:`Redis <debops.redis_server>` and :ref:`memcached <debops.memcached>` support if they are detected on the Roundcube host, which should improve application performance.
  • If LDAP infrastructure is detected on the host, Roundcube will be configured to use the LDAP directory managed by DebOps as an address book.
  • The ManageSieve Roundcube plugin will be enabled by default to allow configuration of Sieve filter scripts. The role will use the DNS SRV resource records to find the Sieve service host and port to use.
  • The role can now use PostgreSQL as a database backend. The database server can be managed with the :ref:`debops.postgresql_server` role.

:ref:`debops.slapd` role

Changed

General

  • Reorder :file:`bootstrap.yml` Ansible playbook to also work for systems freshly installed from CD. :ref:`debops.apt` needs to be run early to regenerate :file:`/etc/apt/sources.list` which might still contain a now not functional CD entry.
  • Most of the role dependencies have been moved either to the playbooks or to the role task lists using the import_role Ansible module.
  • The official DebOps roles have been renamed and the debops. prefix has been dropped from the directory names to better support Ansible Collections. Custom playbooks and role dependencies which use the DebOps roles have to be updated to work again.
  • The :file:`<role_name>/env` "sub-roles" in various DebOps roles have been redesigned for use via the import_role Ansible module to improve support for Ansible Collections. Existing Ansible playbooks that use such "sub-roles" will have to be updated; check the playbooks included in DebOps for the new usage examples.
  • The collections: keyword was added in all DebOps playbooks to support usage with roles, modules and other plugins in an Ansible Collection. Due to this, Ansible 2.8+ is required to use DebOps playbooks.
  • The paths to the passwords stored in the :file:`secret/` directory by various roles have been changed to use the inventory_hostname variable instead of the ansible_fqdn variable. This change will result in passwords set in various services to be regenerated, which might have an impact on service availability. See :ref:`upgrade_notes` for details.

Updates of upstream application versions

  • The RoundCube version installed by the :ref:`debops.roundcube` role has been updated to the 1.4.1 release, which includes a new "Elastic" theme compatible with mobile devices, and other improvements.
  • The Nextcloud version installed by the :ref:`debops.owncloud` role is updated to Nextcloud 16.0 release. The ownCloud version has been updated to 10.3.
  • The Icinga Director version installed by the :ref:`debops.icinga_web` role has been updated to the v1.7.2 release. Notable changes in v1.7.x are new German and Japanese translations, side-by-side sync previews, a new background daemon to replace the job runner and new module dependencies. Other Icinga Web modules have also been updated to their latest versions.

LDAP

  • The authorizedService and host LDAP attribute values used for access control in various DebOps roles and the :file:`ldap/init-directory.yml` playbook have been updated and made consistent with the :ref:`ldap__ref_ldap_access` documentation. You need to update the LDAP entries that use them before applying these changes on the hosts managed by DebOps. See :ref:`upgrade_notes` for detailed list of changed values.

Mail Transport Agents

  • The :envvar:`nullmailer__mailname` and the :envvar:`postfix__mailname` variables will use the host's FQDN address instead of the DNS domain as the mailname. This was done to not include the hostnames in the e-mail addresses, however this is better handled by Postfix domain masquerading done on the mail relay host, which allows for exceptions, supports multiple DNS domains and does not break mail delivery in subtle ways. See the :ref:`debops.nullmailer` role documentation for an example configuration.

:ref:`debops.docker_server` role

:ref:`debops.dovecot` role

  • The role gained support for mail accounts stored in the LDAP directory, based on the :ref:`DebOps LDAP infrastructure <debops.ldap>`. When the LDAP environment is detected on the host, the LDAP support will be enabled automatically, and mail accounts based on POSIX accounts will be disabled.
  • The default mailbox format used by Dovecot has been changed from mbox to Maildir; the user mailboxes will be stored by default in the :file:`~/Maildir/` subdirectory of a given user account. On existing installations, the mailboxes might need to be converted and moved manually.
  • Dovecot will use the host DNS domain as the default SASL realm when users will not specify their domain in their login username.
  • The role should better integrate with the :ref:`DebOps PKI environment <debops.pki>` and gracefully disable TLS support when it has not been configured.
  • The firewall configuration has been redesigned and the :ref:`debops.dovecot` role no longer generates the :command:`ferm` configuration files directly, instead using the :ref:`debops.ferm` role as a dependency.
  • Add option to enable ManageSieve by default without the need to update the config_maps, to allow configuration of Sieve filter scripts.
  • Restored :envvar:`dovecot_mail_location` to original value of maildir:~/Maildir. It was wrongfully changed to /var/vmail/%d/%n/mailbox if LDAP was enabled. See also :envvar:`dovecot_vmail_home`.
  • If the LDAP support is enabled, the role will no longer configure Postfix via the :ref:`debops.postfix` role to deliver local mail via Dovecot LMTP service; this breaks mail delivery to local UNIX accounts (for example root) which might not have corresponding aliases in the virtual mail database. Instead, virtual_transport option will be configured to pass mail via LMTP to Dovecot, which then will deliver it to the virtual mailboxes in :file:`/var/vmail/` subdirectories.

:ref:`debops.icinga_web` role

  • The icinga2-director-jobs.service systemd service has been replaced with icinga-director.service. This service manages a new daemon that is required for Icinga Director v1.7.0+.

:ref:`debops.memcached` role

  • All variables in the role have been renamed from memcached_* to memcached__* to create the role namespace. You need to update the inventory accordingly.

:ref:`debops.nullmailer` role

  • The upstream SMTP relay will be detected automatically using DNS SRV resource records, if they are defined.

:ref:`debops.owncloud` role

  • Drop Nextcloud 15 support because it is EOL. You need to upgrade Nextcloud manually if you are running version 15 or below. The role now defaults to Nextcloud 16 for new installations.

:ref:`debops.postconf` role

:ref:`debops.roundcube` role

  • The variable that defines the FQDN address of the RoundCube installation has been changed from :envvar:`roundcube__domain` to :envvar:`roundcube__fqdn`. The default subdomain has also been changed from roundcube to webmail to offer a more widely used name for the application.

  • The default RoundCube installation path defined in the :envvar:`roundcube__git_dest` variable has been changed and no longer uses the web application FQDN. This should make changing the web application address independent from the installation directory.

    Due to this change, existing installations will be re-installed in the new deployment path. Checking the changes in a development environment is recommended before deploying them in production environment.

  • The role will use DNS SRV resource records to find the IMAP and/or SMTP (submission) services to use in the RoundCube Webmail configuration, with a fallback to static subdomains. See :ref:`roundcube__ref_srv_records` for more details.

  • RoundCube will use the user login and password credentials to authenticate to the SMTP (submission) service before sending e-mail messages. This allows the SMTP server to check the message details, block mail with forged sender address, etc. The default configuration uses encrypted connections to the IMAP and SMTP services to ensure confidentiality and security.

  • User logins that don't specify a domain will have the host domain automatically appended to them during authentication. This solves an issue where use of logins with or without domain for authentication would result in separate RoundCube profiles created in the database.

  • The Roundcube configuration has been redesigned and now uses the custom Ansible filter plugins to generate the :file:`config/config.inc.php` configuration file. The format of the configuration variables has been changed, you will need to update the Ansible inventory. See :ref:`roundcube__ref_configuration` for more details.

  • Roundcube installation tasks have been cleaned up and the old method of keeping track of the :command:`git` checkout is replaced by new functionality of the git Ansible module. This requires full reinstallation of Roundcube application; see :ref:`upgrade_notes` for more details.

  • Support for Roundcube plugins has been redesigned and now uses custom Ansible filters included in DebOps to manage plugins. The role can install plugins from the Roundcube plugin repository and manage their configuration files. A :envvar:`set of default plugins <roundcube__default_plugins>` has been defined to make the default Roundcube installation a bit more user-friendly.

:ref:`debops.ntp` role

  • Chrony will not listen on udp control port on loopback anymore. Unix sockets are a better way for chronyc to talk to chronyd where local access is controlled by file permissions. This is suggested in the Chrony FAQ "How can I make chronyd more secure?".
  • Chrony: Support :envvar:`ntp__listen` value * to make transitioning away from ntpd easier.
  • Chrony: Reduce default NTP servers considered as time source from 4 pool addresses (from which Chrony used 4 NTP servers each – 16 in total) to just 1 pool address – 4 NTP time sources in total.

Removed

General

  • Old [debops_<role_name>] Ansible inventory groups have been removed from DebOps playbooks. Users should use the [debops_service_<role_name>] group names instead.

Fixed

:ref:`debops.docker_server` role

  • Do not add empty entries from docker_server__listen to daemon.json. This causes the docker daemon to not parse the config and crash.

:ref:`debops.ferm` role

  • The dmz firewall configuration will now not interpret the port as part of a IPv6 address anymore. We now protect the IPv6 address by surrounding it by [].

:ref:`debops.gitlab_runner` role

  • Fix issue with GitLab Runner failing test jobs due to the default :file:`~/.bash_logout` script wiping the terminal on logout. The role will skip copying the :file:`/etc/skel/` contents on the new installations; existing script will be removed.

:ref:`debops.nullmailer` role

  • Again, redirect the e-mail messages for local recipients to the central root e-mail account (but local to the SMTP relay). This fixes an issue where e-mail messages were left in the mail queue and filled the disk space.

:ref:`debops.php` role

  • Change the default list of preferred PHP versions to include PHP 7.3 as the preferred version. This should ensure that on hosts with the Ondřej Surý PHP repositories enabled, PHP 7.3 will be installed by default even though newer versions are available. This should solve installation issues with many PHP applications that don't have full support for PHP 7.4+ release yet.

debops v1.2.0 - 2019-12-01

Added

New DebOps roles

  • Add :ref:`debops.postldap` Ansible role to configure and enable :ref:`debops.postfix` to host multiple (virtual) domains,and thus provide email service to several domains with just one mail server. Currently the Virtual Mail support works only with LDAP enabled, in the future mariaDB could be enabled.
  • The :ref:`debops.minio` and :ref:`debops.mcli` Ansible roles can be used to install and configure MinIO object storage service and its corresponding client binary.
  • The :ref:`debops.tinyproxy` role can be used to set up a lightweight HTTP/HTTPS proxy for an upstream server.
  • The :ref:`debops.libuser` Ansible role configures the libuser library and related commands. This library is used by some of the other DebOps roles to manage local UNIX accounts and groups on LDAP-enabled hosts.

General

LDAP

  • The :file:`ldap/init-directory.yml` Ansible playbook will create the LDAP objects cn=LDAP Replicators and cn=Password Reset Agents to allow other Ansible roles to utilize them without the need for the system administrator to define them by hand.
  • The :file:`ldap/get-uuid.yml` Ansible playbook can be used to convert LDAP Distinguished Names to UUIDs to look up the password files if needed.

:ref:`debops.apt_install` role

  • The open-vm-tools APT package will be installed by default in VMware virtual machines.

:ref:`debops.dnsmasq` role

  • The role will tell the client applications to disable DNS-over-HTTPS support using the use-application-dns.net DNS record. This should allow connections to internal sites and preserve the split-DNS functionality.

:ref:`debops.dokuwiki` role

:ref:`debops.cron` role

  • The execution time of the hourly, daily, weekly and monthly :command:`cron` jobs will be randomized on a per-host basis to avoid large job execution spikes every morning. See the role documentation for more details.

:ref:`debops.nullmailer` role

:ref:`debops.pki` role

  • Newly created PKI realms will have a new :file:`public/full.pem` file which contains the full X.509 certificate chain, including the Root CA certificate, which might be required by some applications that rely on TLS.

    Existing PKI realms will not be modified, but Ansible roles that use the PKI infrastructure might expect the new files to be present. It is advisable to :ref:`recreate the PKI realms <pki__ref_realm_renewal>` when possible, or create the missing files manually.

:ref:`debops.saslauthd` role

  • The role can now be used to authenticate users of different services against the LDAP directory via integration with the :ref:`debops.ldap` role and its framework. Multiple LDAP profiles can be used to provide different access control for different services.

:ref:`debops.slapd` role

  • Add support for :ref:`eduPerson LDAP schema <slapd__ref_eduperson>` with updated schema file included in the role.

  • The role will configure SASL authentication in the OpenLDAP service using the :ref:`debops.saslauthd` Ansible role. Both humans and machines can authenticate to the OpenLDAP directory using their respective LDAP objects.

  • The :ref:`lastbind overlay <slapd__ref_lastbind_overlay>` will be enabled by default. This overlay records the timestamp of the last successful bind operation of a given LDAP object, which can be used to, for example, check the date of the last successful login of a given user account.

  • Add support for :ref:`nextcloud LDAP schema <slapd__ref_nextcloud>` which provides attributes needed to define disk quotas for Nextcloud user accounts.

  • The Access Control List rules can now be tested using the 👨`slapacl(8)` command via a generated :ref:`test suite script <slapd__ref_acl_tests>`.

  • The default ACL rules have been overhauled to add support for the ou=Roles,dc=example,dc=org subtree and use of the organizationalRole LDAP objects for authorization. The old set of rules is still active to ensure that the existing environments work as expected.

    If you use a modified ACL configuration, you should include the new rules as well to ensure that changes in the :ref:`debops.ldap` support are working correctly.

  • You can now hide specific LDAP objects from unprivileged users by adding them to a special cn=Hidden Objects,ou=Groups,dc=example,dc=org LDAP group. The required ACL rule will be enabled by default; the objects used to control visibility will be created by the :file:`ldap/init-directory.yml` playbook.

  • New "SMS Gateway" LDAP role grants read-only access to the mobile attribute by SMS gateways. This is needed for implementing 2-factor authentication via SMS messages.

:ref:`debops.unbound` role

  • The role will tell the client applications to disable DNS-over-HTTPS support using the use-application-dns.net DNS record. This should allow connections to internal sites and preserve the split-DNS functionality.
  • The role will configure the :command:`unbound` daemon to allow non-recursive access to DNS queries when a host is managed by Ansible locally, with assumption that it's an Ansible Controller host. This change unblocks use of the :command:`dig +trace` and similar commands.

Changed

Updates of upstream application versions

  • In the :ref:`debops.gitlab` role, GitLab version has been updated to 12.2. This is the last release that supports Ruby 2.5 which is included in Debian Buster.
  • In the :ref:`debops.ipxe` role, the Debian Stretch and Debian Buster netboot installer versions have been updated to their next point releases, 9.10 and 10.2 respectively.
  • In the :ref:`debops.netbox` role, the NetBox version has been updated to v2.6.3.

Continuous Integration

  • The $DEBOPS_FROM environment variable can be used to select how DebOps scripts should be installed in the Vagrant environment: either devel (local build) or pypi (installation from PyPI repository). This makes Vagrant environment more useful on Windows hosts, where :file:`/vagrant` directory is not mounted due to issues with symlinks.
  • The :command:`make test` command will not run the Docker tests anymore, to make the default tests faster. To run the Docker tests with all other tests, you can use the :command:`make test docker` command.

General

  • External commands used in the DebOps scripts have been defined as constants to allow easier changes of the command location in various operating systems, for example Guix.

  • The default Ansible callback plugin used by DebOps is changed to yaml, which gives a cleaner look for various outputs and error messages. The callback plugin will be active by default in new DebOps project directories; in existing directories users can add:

    [ansible defaults]
    stdout_callback = yaml

    in the :file:`.debops.cfg` configuration file.

LDAP

  • The :file:`ldap/init-directory.yml` playbook has been updated to use the new ou=Roles,dc=example,dc=org LDAP subtree, which will contain various organizationalRole objects. After updating the OpenLDAP Access Control List using the :ref:`debops.slapd` role, you can use the playbook on an existing installation to create the missing objects.

    The cn=UNIX Administrators and cn=UNIX SSH users LDAP objects will be created in the ou=Groups,dc=example,dc=org LDAP subtree. On existing installations, these objects need to be moved manually to the new subtree, otherwise the playbook will try to create them and fail due to duplicate UID/GID numbers which are enforced to be unique. You can move the objects using an LDAP client, for example Apache Directory Studio.

    The ou=System Groups,dc=example=dc,org subtree will not be created anymore. On existing installations this subtree will be left intact and can be safely removed after migration.

  • The access to the OpenLDAP service configured using the :ref:`debops.slapd` role now requires explicit firewall and TCP Wrappers configuration to allow access from trusted IP addresses and subnets. You can use the slapd__*_allow variables in the Ansible inventory to specify the IP addresses and subnets that can access the service.

    To preserve the old behaviour of granting access by default from anywhere, you can set the :envvar:`slapd__accept_any` variable to True.

:ref:`debops.apt_preferences` role

:ref:`debops.gitlab` role

  • The LDAP support in GitLab has been converted to use the :ref:`debops.ldap` infrastructure and not configure LDAP objects directly. LDAP support in GitLab will be enabled automatically if it's enabled on the host. Some of the configuration variables have been changed; see the :ref:`upgrade_notes` for more details.

  • The default LDAP filter configured in the :envvar:`gitlab__ldap_user_filter` variable has been modified to limit access to the service to objects with specific attributes. See the :ref:`GitLab LDAP access control <gitlab__ref_ldap_dit_access>` documentation page for details about the required attributes and their values.

  • The GitLab project has changed its codebase structure, because of that the Gitlab CE :command:`git` repository has been moved to a new location, https://gitlab.com/gitlab-org/gitlab-foss/. The role has been updated accordingly. Existing installations should work fine after the new codebase is cloned, but if unsure, users should check the change first in a development environment.

    More details can be found in GitLab blog posts here and here, as well as the Frequently Asked Questions page.

:ref:`debops.golang` role

  • The role has been redesigned from the ground up, and can be used to install Go applications either from APT packages, build them from source, or download precompiled binaries from remote resources. See the role documentation for more details.

:ref:`debops.ldap` role

  • The role will reset the LDAP host attributes defined in the :envvar:`ldap__device_attributes` variable on first configuration in case that the host has been reinstalled and some of their values changed (for example different IP addresses). This should avoid leaving the outdated attributes in the host LDAP object.

:ref:`debops.nginx` role

  • The role will create the webroot directory specified in the item.root parameter even if the item.owner and item.group parameters are not defined. This might have idempotency issues if the :ref:`debops.nginx` role configuration and the application role configuration try to modify the same directory attributes. To disable the webroot creation, you can set the item.webroot_create parameter to False. Alternatively, you should specify the intended owner, group and directory mode in the :command:`nginx` server configuration.

:ref:`debops.nullmailer` role

:ref:`debops.owncloud` role

  • Drop Nextcloud 14 support because it is EOL. You need to upgrade Nextcloud manually if you are running 14 or below. Add Nextcloud 16 support. Now default to Nextcloud 15 for new installations.
  • The LDAP support in Nextcloud has been converted to use the :ref:`debops.ldap` infrastructure and not configure LDAP objects directly. LDAP support in Nextcloud will be enabled automatically if it's enabled on the host. Some of the configuration variables have been changed; see the :ref:`upgrade_notes` for more details.
  • The default LDAP filter configured in the :envvar:`owncloud__ldap_login_filter` variable has been modified to limit access to the service to objects with specific attributes. See the :ref:`Nextcloud LDAP access control <owncloud__ref_ldap_dit_access>` documentation page for details about the required attributes and their values.
  • The default LDAP group filter configured in the :envvar:`owncloud__ldap_group_filter` variable has been modified to limit the available set of groupOfNames LDAP objects to only those that have the nextcloudEnabled attribute set to true.
  • Support for disk quotas for LDAP users has been added in the default configuration, based on the :ref:`nextcloud LDAP schema <slapd__ref_nextcloud>`. The default disk quota is set to 10 GB and can be changed using the nextcloudQuota LDAP attribute.

:ref:`debops.postconf` role

  • Support for the 465 TCP port for message submission over Implicit TLS is no longer deprecated (status changed by the RFC 8314 document) and will be enabled by default with the auth capability.
  • The role will configure Postfix to check the sender address of authenticated mail messages and block those that don't belong to the authenticated user. This will be enabled with the auth and the unauth-sender capabilities, and requires an user database to work correctly.

:ref:`debops.postfix` role

  • The default primary group of the lookup tables has been changed to postfix, default mode for new lookup tables will be set to 0640. This change helps secure lookup tables that utilize remote databases with authentication.
  • Postfix lookup tables can now use shared connection configuration defined in a YAML dictionary to minimize data duplication. See the :ref:`postfix__ref_lookup_tables` documentation for more details.

:ref:`debops.resolvconf` role

  • The role will install and configure :command:`resolvconf` APT package only on hosts with more than one network interface (not counting lo), or if local DNS services are also present on the host.

:ref:`debops.slapd` role

  • Enable substring index for the sudoUser attribute from the :ref:`sudo LDAP schema <slapd__ref_sudo>`. Existing installations should be updated manually via the LDAP client, by setting the value of the sudoUser index to eq,sub.
  • Add indexes for the authorizedService and host attributes from the :ref:`ldapns LDAP schema <slapd__ref_ldapns>` and the gid attribute from the :ref:`posixGroupId LDAP schema <slapd__ref_posixgroupid>`. This should improve performance in UNIX environments connected to the LDAP directory.
  • The number of rounds in SHA-512 password hashes has been increased from 5000 (default) to 100001. Existing password hashes will be unaffected.
  • The employeeNumber attribute in the ou=People,dc=example,dc=org LDAP subtree will be constrained to digits only, and the LDAP directory will enforce its uniqueness in the subtree. This allows the attribute to be used for correlation of personal LDAP objects to RDBMS-based databases.
  • The mail attribute is changed from unique for objects in the ou=People,dc=example,dc=org LDAP subtree to globally unique, due to its use for authentication purposes. The attribute will be indexed by default.
  • Access to the carLicense, homePhone and homePostalAddress attributes has been restricted to privileged accounts only (administrators, entry owner). The values cannot be seen by unprivileged and anonymous users.
  • Write access to the ou=SUDOers,dc=example,dc=org LDAP subtree has been restricted to the members of the "UNIX Administrators" LDAP group.

:ref:`debops.sshd` role

debops-contrib.dropbear_initramfs role

  • Better default value for dropbear_initramfs__network_device by detecting the default network interface using Ansible facts instead of the previously hard-coded eth0.

Removed

:ref:`debops.ansible_plugins` role

  • The ldappassword Ansible filter plugin has been removed as it is no longer used in DebOps roles. The preferred method for storing passwords in LDAP is to pass them in plaintext (over TLS) and let the directory server store them in a hashed form. See also: RFC 3062.

:ref:`debops.ldap` role

  • The use of the params option in the ldap_attrs and ldap_entry Ansible modules is deprecated due to their insecure nature. As a consequence, the :ref:`debops.ldap` role has been updated to not use this option and the ldap__admin_auth_params variable has been removed.

:ref:`debops.nginx` role

  • Set nginx_upstream_php5_www_data to absent. If you are still using that Nginx upstream which was enabled by default then update your Ansible role and switch to a supported PHP release.

Fixed

General

  • The "Edit on GitHub" links on the role default variable pages in the documentation have been fixed and now point to the correct source files on GitHub.

:ref:`debops.dnsmasq` role

  • On Ubuntu hosts, the role will fix the configuration installed by the :command:`lxd` package to use bind-dynamic option instead of bind-interfaces. This allows the :command:`dnsmasq` service to start correctly.

:ref:`debops.ferm` role

  • The dmz firewall configuration will use the dport parameter instead of port, otherwise filtering rules will not work as expected.

:ref:`debops.nfs_server` role

:ref:`debops.nginx` role

  • Fix an issue in the :file:`php.conf.j2` server template when an item.location parameter is specified, overridding the default set of location blocks defined in the :file:`default.conf.j` template. If the / location is not specified in the item.location dictionary, a default one will be included by the role.

:ref:`debops.postconf` role

  • Disable the smtpd_helo_restrictions option on the submission and smtps TCP ports when the authentication and MX lookups are enabled. This should fix an issue where SMTP client sends the host's IP address as its HELO/EHLO response, which might not be configurable by the user.

Security

:ref:`debops.nginx` role

:ref:`debops.owncloud` role

debops v1.1.0 - 2019-08-25

Added

New DebOps roles

  • The :ref:`debops.keyring` role is designed to be used by other Ansible roles to manage the GPG keys, either in the APT keyring or the GPG keyrings of specific UNIX accounts. It replaces and centralizes the use of the apt_key and the apt_repository Ansible modules in separate roles and provides additional functionality, like GPG key lookup in a local key store on the Ansible Controller, or the Keybase service.
  • The debops-contrib.neurodebian Ansible role has been migrated to the main DebOps role namespace as the :ref:`debops.neurodebian` role. This role can be used to configure the NeuroDebian APT repository on Debian/Ubuntu hosts.
  • The :ref:`debops.wpcli` role can be used to install the WP-CLI framework to allow management of WordPress websites in a shared hosting environment.
  • The :ref:`debops.nscd` role configures the Name Service Cache Daemon, used to cache NSS entries from remote databases, for example LDAP, Active Directory or NIS. The role is included in the :file:`bootstrap-ldap.yml` playbook.
  • The :ref:`debops.backup2l` role configures the backup2l script which can create differential backups of a given host and store them on an external hard drive connected to that host.
  • The :ref:`debops.resolvconf` role fixes a few issues in the resolvconf Debian package and modifies the interface order in the generated :file:`/etc/resolv.conf` configuration file depending on presence of a local DNS resolver like dnsmasq or unbound. The role is included in the bootstrap and common playbooks.

Continuous Integration

General

  • The pyopenssl Python package has been added as a dependency of DebOps when the project is installed with Ansible included. This package is required by the openssl_* modules in Ansible 2.7; some of the DebOps roles like :ref:`debops.opendkim` use these modules on the Ansible Controller.
  • The distro Python package has been added as the DebOps dependency. The package is used by the :command:`debops-init` script to detect the operating system used on the Ansible Controller, and is a replacement for the deprecated platform.linux_distribution() function.

LDAP

  • The :file:`ldap/init-directory.yml` Ansible playbook will create an LDAP group object for SSH users, equivalent to the sshusers group created by the :ref:`debops.system_groups` role. LDAP accounts in this group will be able to access SSH service from any host. Existing installations might need to be updated manually to fix UID/GID or LDAP DN conflicts.

:ref:`debops.ferm` role

  • If Avahi/mDNS support is present on a host, the :ref:`debops.ferm` role will allow access through the mdns UDP port by default. This will most likely happen on workstations and laptops with full desktop environments installed, but not on servers with minimal install. To configure Avahi service or enable it on servers, you can use the :ref:`debops.avahi` Ansible role.

:ref:`debops.libvirtd` role

  • The role will configure the libvirt and libvirt_guest NSS modules in :file:`/etc/nsswitch.conf` database using the :ref:`debops.nsswitch` role to allow accessing the virtual machines or containers via their hostnames on the virtual machine host.

:ref:`debops.lxc` role

  • The :command:`lxc-prepare-ssh` script can now look up the SSH keys of the current user in LDAP if support for it is enabled on the LXC host.

:ref:`debops.nginx` role

  • Add support to disable logging per Nginx server.
  • If a :command:`nginx` server configuration uses a domain with lxc. prefix, for example inside of an internal LXC container, the role will include a redirect from host.lxc "virtual" domain to the real host.lxc.example.org domain. This ensures that HTTP requests to the http://host.lxc/ URLs are redirected to the real LXC container hosts, depending on the DNS records and the HTTP client's resolver configuration.

:ref:`debops.slapd` role

  • The role can now control on which ports and services OpenLDAP listens for connections. The ldaps:/// service is enabled by default when support for the :ref:`debops.pki` role is enabled on the OpenLDAP host.

:ref:`debops.sysctl` role

  • The kernel protection for symlinks and hardlinks will be enabled by default on Debian/Ubuntu hosts.
  • Don't use special configuration for containers to determine what kernel parameters can be modified. The role will rely on its own Ansible local facts for that.

:ref:`debops.unbound` role

  • The :command:`unbound` service will be configured to forward *.lxc.{{ ansible_domain }} DNS queries to the :command:`dnsmasq` service managed by the :ref:`debops.lxc` role (lxc-net), if LXC configuration is detected via local Ansible facts. The *.consul DNS queries will be forwarded to the :command:`consul` service, if its Ansible facts are detected.

:ref:`debops.users` role

Changed

Updates of upstream application versions

  • The :ref:`debops.netbox` role has been updated to NetBox version v2.6.1. Redis service is now required for NetBox; it can be installed separately via the :ref:`debops.redis_server` Ansible role.

    The NetBox version installed by DebOps has been changed from using the master branch, to specific tags, with the latest release (v2.6.1) set by default. The :command:`git` commit signature in the NetBox repository is also verified using the GitHub GPG key when the repository is cloned.

  • In the :ref:`debops.cran` role, the upstream APT repository suite for CRAN has been updated to <release>-cran35/ due to changes in APT repository structure. Existing APT repository URLs might need to be removed manually from :file:`/etc/apt/sources.lists.d/` directory to make the APT service work as expected.

  • The :ref:`debops.nodejs` role will now install NodeJS, NPM and Yarn packages from the OS release repository by default. On the Debian Oldstable release, the packages backported from the Debian Stable release will be used by default. Installation of upstream NodeJS and NPM can be enabled using the :envvar:`nodejs__node_upstream` variable. Upstream Yarn can be enabled using the :envvar:`nodejs__yarn_upstream` variable.

    If the NodeJS upstream support is enabled, the NodeJS 8.x version will be installed on older Debian/Ubuntu releases, for example Debian Stretch and Ubuntu Bionic. Debian Buster and newer releases will use NodeJS 10.x version, to keep the Node version from upstream in sync with the one available in the OS repositories.

  • In the :ref:`debops.etherpad` role, the default version installed by the role is changed from the develop branch to the v1.7.0 version on older OS releases, and the v1.7.5 version on Debian Buster and newer, to not force installation of the upstream NPM package by default.

Continuous Integration

  • DebOps now uses xenial as the default OS release used in Travis-CI tests. The xenial images on Travis use the :command:`shellcheck` v0.6.0 to test shell scripts; if you want to run the :command:`test shell` command locally to check the script syntax, you will need to update your :command:`shellcheck` installation to the v0.6.0 version to match the one on Travis-CI. This version is at present not available in Debian, therefore a custom install will be needed. See the ShellCheck install instructions for your preferred method.
  • The Travis-CI tests will be done using Python 3.7 only. Python 2.7 support will be dropped in 2020, it's time to prepare.
  • The GitLab CI tests are done using a debian/buster64 Vagrant Box.

Docker

General

  • Various DebOps roles have been modified to use the :ref:`debops.keyring` Ansible role to manage the APT repository keys, or GPG keys on UNIX accounts. If you are using them in custom playbooks, you might need to update them to include the new dependency.
  • The installation of APT and other packages in DebOps roles has been refactored to remove the use of the with_items/with_flattened lookups. Support for package installation via task loops will be removed in Ansible 2.11.
  • The DebOps documentation generator now supports Ansible roles with multiple :file:`defaults/main/*.yml` files. They are also correctly handled by the :command:`debops-defaults` script.
  • Various DebOps roles will no longer use the hostname as a stand-in for an empty DNS domain when no DNS domain is detected - this resulted in the "standalone" hosts without a DNS domain to be misconfigured. Existing setups with a DNS domain shouldn't be affected, but configuration of standalone hosts that deploy webservices might require modifications.
  • The :ref:`debops.resolvconf` role has been added as a dpendency in the Ansible playbooks of the roles that interact with the resolvconf service in some way. The modified roles are: :ref:`debops.dnsmasq`, :ref:`debops.docker_server`, :ref:`debops.ifupdown`, :ref:`debops.lxc`, :ref:`debops.unbound`. The installation of the resolvconf APT package has been removed from the roles that contained it.
  • Run :ref:`debops.apt_proxy` from the :file:`bootstrap.yml` Ansible playbook to ensure that if a proxy is used, it is used all the time without disabling the proxy for a short while during bootstrapping. The :file:`bootstrap-ldap.yml` Ansible playbook already included :ref:`debops.apt_proxy`.

User management

:ref:`debops.avahi` role

  • The :command:`avahi-alias` script has been imported into the role itself and will no longer be installed by cloning the upstream :command:`git` repository. Consequently, support for mDNS *.local CNAME resource records will be enabled by default on hosts with Python 2.7 installed (support for Python 3.x is currently not available).

:ref:`debops.dokuwiki` role

  • The patchpanel DokuWiki plugin has been deprecated in favor of the switchpanel plugin. The role will remove the patchpanel plugin automatically on existing installations. You might need to update the wiki contents to render the patch panels correctly, see the plugin documentation for more details.

:ref:`debops.docker_server` role

  • The debops.docker role has been renamed to :ref:`debops.docker_server` in preparation of adding a role that will provide client functionality like network and container management.

  • The Docker server no longer listens on a TCP port by default, even if :ref:`debops.pki` is enabled.

  • The default storage driver used by the :ref:`debops.docker_server` has been changed to overlay2 which is the default in upstream. The role checks the currently enabled storage driver via Ansible local facts, and should preserve the current configuration on existing installations.

    If needed, the storage driver in use can be overridden via the :envvar:`docker_server__storage_driver` variable.

:ref:`debops.etckeeper` role

  • The installation of :command:`etckeeper` will be disabled by default in Python 3.x-only environments.

:ref:`debops.gitlab` role

  • The playbook will no longer force the installation of the upstream Node.js and Yarn packages via the :ref:`debops.nodejs` role. The upstream versions are currently not required on Debian Buster.

:ref:`debops.ifupdown` role

  • The role will not install the rdnssd APT package if NetworkManager service is detected on the host, to avoid removing the NM service due to package conflict. NetworkManager should gracefully handle adding IPv6 nameservers to :file:`/etc/resolv.conf` file, and on systems without NM installed the :command:`rdnssd` script will perform this task as before.

:ref:`debops.ipxe` role

  • The role has been redesigned from scratch, and now supports multiple Debian Netboot installers; the iPXE scripts are defined in default variables instead of the file-based templates and can be easily modified via the Ansible inventory.

:ref:`debops.kmod` role

  • The role will use the :ref:`debops.python` Ansible role to install the kmodpy Python package in Python 2.7 environments. Because the package is not available in Debian as Python 3.x module, the kmod.fact local fact script will use the :command:`lsmod` command to list the kernel modules in this case.
  • The role gained basic support for defining what kernel modules should be loaded on non-systemd hosts by adding them in the :file:`/etc/modules` configuration file.

:ref:`debops.libvirt` role

  • The virt-goodies package will be installed only if the Python 2.7 environment is already present on the host.

:ref:`debops.lxc` role

  • The role now checks the version of the installed LXC support and uses the old or new configuration keys accordingly. You can review the changed configuration keys between the old and new LXC version for comparsion.

  • New LXC containers will have the CAP_SYS_TIME POSIX capability dropped by default to ensure that time configuration is disabled inside of the container. This should fix an issue on Debian Buster where unprivileged LXC containers still have this capability enabled.

    On Debian Buster LXC hosts, the CAP_SYS_ADMIN POSIX capability will be dropped in new LXC containers by default.

  • On Debian Buster (specifically on LXC versions below 3.1.0) the AppArmor restrictions on unprivileged LXC containers will be relaxed to allow correct operation of the :command:`systemd` service manager inside of a container. Check the Debian Bugs #916644, #918839 and #911806 for reasoning behind this modification.

  • Restrict configuration of the :file:`poweroff.conf` :command:`systemd` override to Debian Stretch and Ubuntu Xenial only. The containers correctly shut down using SIGRTMIN+3 signal on Debian Buster and beyond.

:ref:`debops.mariadb_server` role

  • The role will no longer set a custom MariaDB root password, because the mysql_user Ansible 2.8 module breaks access to the MariaDB database via the UNIX root account by removing the unix_socket plugin access and not setting the mysql_native_password plugin. A password for the UNIX root account is not needed in the recent MariaDB releases in Debian, therefore this shouldn't impact the usage.

    The mysql_user Ansible module lacks a way to control the authentication plugin for a given MariaDB account, therefore it's not advisable to mess with the root access to the database.

:ref:`debops.netbase` role

  • Do not try to manage the hostname in LXC, Docker or OpenVZ containers by default. We assume that these containers are unprivileged and their hostname cannot be changed from the inside of the container.
  • If a host does not have a proper domain, either defined locally or set via the DNS, don't generate a faux "domain" based on its hostname and assume that this is a standalone host. This might affect availability of some services, for example X.509 certificates managed by :ref:`debops.pki` or reachability of websites created on that host. In this case the host cannot have a FQDN defined in the Ansible inventory as the label or ansible_host variable, only a hostname.
  • Role will check if the configured FQDN of a host exists in the DNS database. If it does, the entry in the :file:`/etc/hosts` file will be removed to allow the DNS to take over. If it doesn't, the configuration will be left intact with assumtion that the domain is configured locally.

:ref:`debops.nginx` role

  • The role will no longer default to limiting the allowed HTTP request methods to GET, HEAD and POST on PHP-enabled websites.

:ref:`debops.pki` role

  • If there is no domain set on the remote host, don't fallback to the hostname in the :envvar:`pki_ca_domain` variable because the generated CA certificates don't make any sense. With this setup the :ref:`debops.pki` role requires to be run against a host with a valid DNS domain for the internal CA to be created.

:ref:`debops.rsnapshot` role

  • The role has been redesigned from the ground up. Instead of using Ansible inventory groups to define hosts to back up, role uses a list of YAML dictionaries with hosts defined explicitly; the old behaviour can be replicated if needed. The backup host itself can also be snapshotted, with support for snapshots on removable media.

:ref:`debops.snmpd` role

  • The local SNMPv3 username and password will be stored in a separate file and retrieved via Ansible local facts, to not break Ansible fact gathering on unprivileged accounts. The password file is protected by strict read permission and accessible only by the root UNIX account.

:ref:`debops.system_groups` role

  • Don't configure the NOPASSWD: tag for the %admins and %wheel UNIX groups in :command:`sudo` by default when Ansible manages the local host. This allows local admin accounts to control root access using a password.

:ref:`debops.system_users` role

  • The role will set a custom shell based on the users' own shell for the dynamic UNIX account only if the shell is known by the role. This should avoid issues when Ansible users use non-standard shells on Ansible Controller.

:ref:`debops.tftpd` role

  • The role has been refreshed in conjunction with the updates to network boot services in preparation for Debian Buster. All of the role variables have been renamed to put them in their own tftpd__* namespace, and the role dependencies have been moved to the playbook.

:ref:`debops.unbound` role

Removed

Roles removed from DebOps

  • The debops.openvz role has been removed. OpenVZ is not supported in Debian natively since Wheezy; a good replacement for it is LXC which can be managed using the :ref:`debops.lxc` role.

:ref:`debops.core` role

:ref:`debops.docker_server` role

  • Support for ferment has been removed from DebOps due to the upstream not being up to date anymore, both with Docker as well as with Python 3.x support. The :command:`dockerd` daemon will be restarted on any :command:`ferm` restarts to update the firewall configuration with Docker rules.

:ref:`debops.lxc` role

  • The :command:`lxc-prepare-ssh` script will no longer install SSH keys from the LXC host root account on the LXC container root account. This can cause confusion and unintended security breaches when other services (for example backup scripts or remote command execution tools) install their own SSH keys on the LXC host and they are subsequently copied inside of the LXC containers created on that host.

:ref:`debops.nodejs` role

  • [debops.nodejs] Support for installing NPM from its :command:`git` repository has been removed. NPM is included in the NodeSource upstream nodejs package, as well as the Debian archive since Debian Buster release in the npm package.

Fixed

:ref:`debops.apache` role

  • Refactor the role to not use Jinja 'import' statements in looped tasks - this does not work on newer Jinja versions.

:ref:`debops.lvm` role

  • Make sure logical volumes will only be shrinked when volume item defines force: yes.

:ref:`debops.nsswitch` role

:ref:`debops.python` role

  • The role should now correctly detect Python 3.x interpreter on the Ansible Controller and disable usage of Python 2.7 on the managed hosts.

debops v1.0.0 - 2019-05-22

Added

New DebOps roles

  • The :ref:`debops.docker_registry` role provides support for Docker Registry. The role can be used as standalone or as a backend for the GitLab Container Registry service, with :ref:`debops.gitlab` role.
  • The :ref:`debops.ldap` role sets up the system-wide LDAP configuration on a host, and is used as the API to the LDAP directory by other Ansible roles, playbooks, and users via Ansible inventory. The role is included in the common.yml playbook, but is disabled by default.
  • The :ref:`debops.nslcd` role can be used to configure LDAP lookups for NSS and PAM services on a Linux host.
  • The :ref:`debops.pam_access` role manages PAM access control files located in the :file:`/etc/security/` directory. The role is designed to allow other Ansible roles to easily manage their own PAM access rules.
  • The :ref:`debops.yadm` role installs the Yet Another Dotfiles Manager script and ensures that additional shells are available. It can also mirror dotfiles locally. The role is included in the common playbook.
  • The :ref:`debops.system_users` role replaces the debops.bootstrap role and is used to manage the local system administrator accounts. It is included in the :file:`common.yml` playbook as well as the bootstrap playbooks.

General

  • The DebOps project has been registered in the IANA Private Enterprise Numbers registry, with PEN number 53622. The project documentation contains :ref:`an OID registry <debops_oid_registry>` to track custom LDAP schemas, among other things.
  • Support for Ansible Collections managed by the Mazer Content Manager has been implemented in the repository. Ansible Collections will be usable after June 2019, when support for them is enabled in the Ansible Galaxy service.

LDAP

  • A new :file:`bootstrap-ldap.yml` Ansible playbook can be used to bootstrap Debian/Ubuntu hosts with LDAP support enabled by default. The playbook will configure only the services required for secure LDAP access (PKI, SSH, PAM/NSS), the rest should be configured using the common playbook.

:ref:`debops.ansible_plugins` role

  • A new ldap_attrs Ansible module has been added to the role. It's a replacement for the ldap_attr core Ansible module, that's more in line with the ldap_entry module. Used by the :ref:`debops.slapd` and :ref:`debops.ldap` roles to manage the LDAP directory contents.

:ref:`debops.apt` role

  • Systems with the End of Life Debian releases (wheezy) installed will be configured to use the Debian Archive repository as the main APT sources instead of the normal Debian repository mirrors. These releases have been moved out of the main repositories and are not fully available through normal means. The periodic updates of the APT archive repositories on these systems will be disabled via the :ref:`debops.unattended_upgrades` role, since the EOL releases no longer receive updates.

    The Debian LTS release (jessie) APT repository sources will use only the main and security repositories, without updates or backports. See the information about the Debian LTS support for more details.

:ref:`debops.lxc` role

  • Users can now disable default route advertisement in the lxc-net DHCP service. This is useful in cases where LXC containers have multiple network interfaces and the default route should go through a different gateway than the LXC host.
  • The :command:`lxc-new-unprivileged` script will add missing network interface stanzas in the container's :file:`/etc/network/interfaces` file, by default with DHCP configuration. This will happen only on the initialization of the new container, when a given LXC container has multiple network interfaces defined in its configuration file.

:ref:`debops.nginx` role

  • The role will automatically generate configuration which redirects short hostnames or subdomains to their FQDN equivalents. This allows HTTP clients to reach websites by specifying their short names via DNS suffixes from :file:`/etc/resolv.conf` file, or using *.local domain names managed by Avahi/mDNS to redirect HTTP clients to the correct FQDNs.

:ref:`debops.resources` role

  • Some lists can now configure ACL entries on the destination files or directories using the item.acl parameter. Take a look to :ref:`resources__ref_acl` section to have the list of compatibles variables.
  • New :ref:`resources__ref_commands` variables can be used to define simple shell commands or scripts that will be executed at the end of the :ref:`debops.resources` role. Useful to start new services, but it shouldn't be used as a replacement for a fully-fledged Ansible roles.

:ref:`debops.sudo` role

  • The role is now integrated with the :ref:`debops.ldap` Ansible role and can configure the :command:`sudo` service to read sudoers configuration from the LDAP directory.

:ref:`debops.users` role

  • The role can now configure UNIX accounts with access restricted to SFTP operations (SFTPonly) with the new item.chroot parameter. This is a replacement for the debops.sftpusers role.

Changed

Updates of upstream application versions

  • The :ref:`debops.gitlab` role will install GitLab 11.10 on supported platforms (Debian Buster, Ubuntu Bionic), existing installations will be upgraded.
  • In the :ref:`debops.phpipam` role, the relevant inventory variables have been renamed, check the :ref:`upgrade_notes` for details. The role now uses the upstream phpIPAM repository and it installs version 1.3.2.
  • In the :ref:`debops.php` role, because of the PHP 7.0 release status changed to End of life at the beginning of 2019, Ondřej Surý APT repository with PHP 7.2 packages will be enabled by default on Debian Jessie and Stretch as well as Ubuntu Trusty and Xenial. Existing :ref:`debops.php` installations shouldn't be affected, but the role will not try to upgrade the PHP version either. Users should consider upgrading the packages manually or reinstalling services from scratch with the newer version used by default.
  • In the :ref:`debops.rstudio_server` role, the supported version has been updated to v1.2.1335. The role no longer installs libssl1.0.0 from Debian Jessie on Debian Stretch, since the current version of the RStudio Server works in the default Stretch environment. The downloaded .deb package will be verified using the RStudio Inc. GPG signing key before installation.
  • In the :ref:`debops.docker_gen` role, the docker-gen version that this role installs by default has been updated to version 0.7.4. This release notably adds IPv6 and docker network support.

General

Mail Transport Agents

  • The :file:`/etc/mailname` configuration file will contain the DNS domain of a host instead of the FQDN address. This will result in the mail senders that don't specify the domain part to have the DNS domain, instead of the full host address, added by the Mail Transport Agent. This configuration should work better in clustered environments, where there is a central mail hub/MX that receives the mail and redirects it.

:ref:`debops.gitlab` role

  • The GitLab playbook will import the :ref:`debops.docker_registry` playbook to ensure that configuration related to Docker Registry defined in the GitLab service is properly applied during installation/management.

:ref:`debops.lxc` role

  • The :command:`lxc-prepare-ssh` script will read the public SSH keys from specific files (root key file, and the $SUDO_USER key file) and will not accept any custom files to read from, to avoid possible security issues. Each public SSH key listed in the key files is validated before being added to the container's root account.

    The :command:`lxc-new-unprivileged` script will similarly not accept any custom files as initial LXC container configuration to fix any potential security holes when used via :command:`sudo`. The default LXC configuration file used by the script can be configured in :file:`/etc/lxc/lxc.conf` configuration file.

:ref:`debops.mariadb_server` role

  • The MariaDB user root is no longer dropped. This user is used for database maintenance and authenticates using the unix_auth plugin. However, DebOps still maintains and sets a password for the root UNIX account, stored in the :file:`/root/.my.cnf` config file.

:ref:`debops.netbase` role

  • The role will be disabled by default in Docker containers. In this environment, the :file:`/etc/hosts` file is managed by Docker and cannot be modified from inside of the container.

:ref:`debops.owncloud` role

  • The role will not perform any tasks related to :command:`occ` command if the automatic setup is disabled in the :envvar:`owncloud__autosetup` variable. In this mode, the :command:`occ` tasks cannot be performed by the role because the ownCloud/Nextcloud installation is not finished. The users are expected to perform necessary tasks themselves if they decide to opt-out from the automatic configuration.

:ref:`debops.php` role

  • The PHP version detection has been redesigned to use the :command:`apt-cache madison` command to find the available versions. The role will now check the current version of the php APT package to select the available stable PHP version. This unfortunately breaks support for the php5 packages, but the php5.6 packages from Ondřej Surý APT repository work fine.

  • The role will install the :command:`composer` command from the upstream GitHub repository on older OS releases, including Debian Stretch (current Stable release). This is due to incompatibility of the composer APT package included in Debian Stretch and PHP 7.3.

    The custom composer command installation tasks have been removed from the :ref:`debops.roundcube` and :ref:`debops.librenms` roles, since :ref:`debops.php` will take care of the installation.

:ref:`debops.root_account` role

  • If the :ref:`debops.ldap` Ansible role has been applied on a host, the :ref:`debops.root_account` role will use the UID/GID ranges defined by it, which include UIDs/GIDs used in the LDAP directory, to define subUID/subGID range of the root account. This allows usage of the LDAP directory as a source of UNIX accounts and groups in unprivileged containers. Existing systems will not be changed.
  • Management of the root dotfiles has been removed from the :ref:`debops.users` role and is now done in the :ref:`debops.root_account` role, using the :command:`yadm` script. Users might need to clean out the existing dotfiles if they were managed as symlinks, otherwise :command:`yadm` script will not be able to correctly deploy the new dotfiles.

:ref:`debops.slapd` role

  • The role has been redesigned from the ground up, with support for N-Way Multi-Master replication, custom LDAP schemas, Password Policy and other functionality. The role uses custom ldap_attrs Ansible module included in the :ref:`debops.ansible_plugins` role for OpenLDAP management.

    The OpenLDAP configuration will definitely break on existing installations. It's best to set up a new OpenLDAP server (or replicated cluster) and import the LDAP directory to it afterwards. See :ref:`role documentation <debops.slapd>` for more details.

:ref:`debops.sshd` role

  • The access control based on UNIX groups defined in the :file:`/etc/ssh/sshd_config` file has been removed. Instead, the OpenSSH server uses the PAM access control configuration, managed by the :ref:`debops.pam_access` Ansible role, to control access by users/groups/origins. OpenSSH service uses its own access control file, separate from the global :file:`/etc/security/access.conf` file.

  • The role will enable client address resolving using DNS by setting the UseDNS yes option in OpenSSH server configuration. This parameter is disabled by default in Debian and upstream, however it is required for the domain-based access control rules to work as expected.

  • When the LDAP support is configured on a host by the :ref:`debops.ldap` role, the :ref:`debops.sshd` role will use the resulting infrastructure to connect to the LDAP directory and create the sshd LDAP account object for each host, used for lookups of the SSH keys in the directory. The SSH host public keys will be automatically added or updated in the LDAP device object to allow for centralized generation of the ~/.ssh/known_hosts files based on the data stored in LDAP.

    The role will no longer create a separate sshd-lookup UNIX account to perform LDAP lookups; the existing sshd UNIX account will be used instead. The :command:`ldapsearch` command used for lookups will default to LDAP over TLS connections instead of LDAPS.

:ref:`debops.system_groups` role

:ref:`debops.unattended_upgrades` role

  • The packages from the stable-updates APT repository section will be automatically upgraded by default, the same as the packages from Debian Security repository. This should cover important non-security related upgrades, such as timezone changes, antivirus database changes, and similar.
  • If automatic reboots are enabled, VMs will not reboot all at the same time to avoid high load on the hypervisor host. Instead they will reboot at a particular minute in a 15 minute time window. For each host, a random-but-idempotent time is chosen. For hypervisor hosts good presets cannot be picked. You should ensure that hosts don’t reboot at the same time by defining different reboot times in inventory groups.

:ref:`debops.users` role

  • The management of the user dotfiles in the :ref:`debops.users` role has been redesigned and now uses the :command:`yadm` script to perform the actual deployment. See :ref:`debops.yadm` for details about installing the script and creating local dotfile mirrors. The :ref:`users__ref_accounts` variable documentation contains examples of new dotfile definitions.

  • The role now uses the libuser library via the Ansible group and user modules to manage local groups and accounts. This should avoid issues with groups and accounts created in the LDAP user/group ranges.

    The libuser library by default creates home directories with 0700 permissions, which is probably too restrictive. Because of that, the role will automatically change the home directory permissions to 0751 (defined in the :envvar:`users__default_home_mode` variable). This also affects existing UNIX accounts managed by the role; the mode can be overriden using the item.home_mode parameter.

  • The users__*_resources variables have been reimplemented as the item.resources parameter of the users__*_accounts variables. This removes the unnecessary split between user account definitions and definitions of their files/directories.

Removed

Roles removed from DebOps

  • The debops.sftpusers Ansible role has been removed. Its functionality is now implemented by the :ref:`debops.users` role, custom bind mounts can be defined using the :ref:`debops.mount` role.
  • The debops.bootstrap Ansible role has been removed. Its replacement is the :ref:`debops.system_users` which is used to manage system administrator accounts, via the common.yml playbook and the bootstrap playbooks.

:ref:`debops.auth` role

:ref:`debops.rstudio_server` role

  • The role will no longer install the historical libssl1.0.0 APT package on Debian Stretch to support older RStudio Server releases. You should remove it on the existing installations after RStudio Server is upgraded to the newest release.

Fixed

:ref:`debops.authorized_keys` role

  • Set the group for authorized_keys files to the primary group of the user instead of the group with the same name as the user. This is important because otherwise the readonly mode of the role does not work when the primary group of a user has a different name then the username.

:ref:`debops.lvm` role

:ref:`debops.redis_server` role

  • Use the :file:`redis.conf` file to lookup passwords via the :command:`redis-password` script. This file has the redis-auth UNIX group and any accounts in this group should now be able to look up the Redis passwords correctly.

:ref:`debops.slapd` role

  • The role will check if the X.509 certificate and the private key used for TLS communication were correctly configured in the OpenLDAP server. This fixes an issue where configuration of the private key and certificate was not performed at all, without any actual changes in the service, with subsequent task exiting with an error due to misconfiguration.

Security

:ref:`debops.php` role

debops v0.8.1 - 2019-02-02

Added

New DebOps roles

Continuous Integration

  • Ansible roles included in DebOps are now checked using ansible-lint tool. All existing issues found by the script have been fixed.
  • The hosts managed by the DebOps Vagrant environment will now use Avahi to detect multiple cluster nodes and generate host records in the :file:`/etc/hosts` database on these nodes. This allows usage of real DNS FQDNs and hostnames in the test environment without reliance on an external DHCP/DNS services.

General

  • DebOps roles are now tagged with skip::<role_name> Ansible tags. You can use these tags to skip roles without any side-effects; for example "<role_name>/env" sub-roles will still run so that roles that depend on them will work as expected.
  • You can use the :command:`make versions` command in the root of the DebOps monorepo to check currently "pinned" and upstream versions of third-party software installed and managed by DebOps, usually via :command:`git` repositories. This requires the :command:`uscan` command from the Debian devscripts APT package to be present.

:ref:`debops.ifupdown` role

  • The role will now generate configuration for the :ref:`debops.sysctl` role and use it in the playbook as a dependency, to configure kernel parameters related to packet forwarding on managed network interfaces. This functionality replaces centralized configuration of packet forwarding on all network interfaces done by the :ref:`debops.ferm` role.

:ref:`debops.lxc` role

  • New :command:`lxc-hwaddr-static` script can be used to easily generate random but predictable MAC addresses for LXC containers.

    The script can be run manually or executed as a "pre-start" LXC hook to configure static MAC addresses automatically - this usage is enabled by default via common LXC container configuration.

  • The lxc_ssh.py Ansible connection plugin is now included by default in DebOps. This connection plugin can be used to manage remote LXC containers with Ansible via SSH and the :command:`lxc-attach` command. This requires connection to the LXC host and the LXC container via the root account directly, which is supported by the DebOps playbooks and roles.

  • The role can now manage LXC containers, again. This time the functionality is implemented using the lxc_container Ansible module instead of a series of shell tasks. By default unprivileged LXC containers will be created, but users can change all parameters supported by the module.

  • The role will now configure a lxcbr0 bridge with internal DNS/DHCP server for LXC containers, using the lxc-net service. With this change, use of the :ref:`debops.ifupdown` role to prepare a default bridge for LXC containers is not required anymore.

:ref:`debops.netbase` role

  • When a large number of hosts is defined for the :file:`/etc/hosts` database, the role will switch to generating the file using the template Ansible module instead of managing individual lines using the lineinfile module, to make the operation faster. As a result, custom modifications done by other tools in the host database will not be preserved.
  • The role can now configure the hostname in the :file:`/etc/hostname` file, as well as the local domain configuration in :file:`/etc/hosts` database.

:ref:`debops.php` role

  • The role will install the composer APT package on Debian Stretch, Ubuntu Xenial and their respective newer OS releases.

:ref:`debops.root_account` role

  • The role will reserve a set of UID/GID ranges for subordinate UIDs/GIDs owned by the root account (they are not reserved by default). This can be used to create unprivileged LXC containers owned by root. See the release notes for potential issues on existing systems.
  • You can now configure the state and contents of the :file:`/root/.ssh/authorized_keys` file using the :ref:`debops.root_account` role, with support for global, per inventory group and per host SSH keys.

:ref:`debops.users` role

  • The role can now configure ACL entries of the user home directories using the item.home_acl parameter. This can be used for more elaborate access restrictions.

Changed

Continuous Integration

  • The test suite will now check POSIX shell scripts along with Bash scripts for any issues via the :command:`shellcheck` linter. Outstanding issues found in existing scripts have been fixed.

General

  • The :ref:`debops.root_account` role will be executed earlier in the common.yml Ansible playbook to ensure that the root UID/GID ranges are reserved without issues on the initial host configuration.
  • Various filter and lookup Ansible plugins have been migrated from the playbook directory to the :ref:`debops.ansible_plugins` role. This role can be used as hard dependency in other Ansible roles that rely on these plugins.
  • The order of the roles in the common playbook has been changed; the :ref:`debops.users` role will be applied before the :ref:`debops.resources` role to allow for resources owned by UNIX accounts/groups other than root.
  • The debops Python package has dropped the hard dependency on Ansible. This allows DebOps to be installed in a separate environment than Ansible, allowing for example to mix Homebrew Ansible with DebOps from PyPI on macOS. The installation instructions have also been updated to reflect the change.
  • The :command:`debops-init` script will now generate new Ansible inventory files using the hostname as well as a host FQDN to better promote the use of DNS records in Ansible inventory.

:ref:`debops.dnsmasq` role

  • The role has been redesigned from the ground up with new configuration pipeline, support for multiple subdomains and better default configuration. See the :ref:`debops.dnsmasq` role documentation as well as the :ref:`upgrade_notes` for more details.

:ref:`debops.docker_server` role

  • If the Docker host uses a local nameserver, for example :command:`dnsmasq` or :command:`unbound`, Docker containers might have misconfigured DNS nameserver in :file:`/etc/resolv.conf` pointing to 127.0.0.1. In these cases, the :ref:`debops.docker_server` role will configure Docker to use the upstream nameservers from the host, managed by the resolvconf APT package.

    If no upstream nameservers are available, the role will not configure any nameserver and search parameters, which will tell Docker to use the Google nameservers.

:ref:`debops.gitlab` role

  • The role will now install GitLab 10.8 by default, on Debian Stretch and Ubuntu Xenial. The 11.x release now requires Ruby 2.4+, therefore it will only be installed on newer OS releases (Debian Buster, Ubuntu Bionic).

  • The role has been updated to use Ansible local facts managed by the :ref:`debops.redis_server` Ansible role. Redis Server support has been removed from the GitLab playbook and needs to be explicitly enabled in the inventory for GitLab to be installed correctly. This will allow to select between local Server or Sentinel instance, to support clustered environments.

    Check the :ref:`upgrade_notes` for issues with upgrading Redis Server support on existing GitLab hosts.

:ref:`debops.grub` role

  • The GRUB configuration has been redesigned, role now uses merged variables to make configuration via Ansible inventory or dependent role variables easier. The GRUB configuration is now stored in the :file:`/etc/default/grub.d/` directory to allow for easier integration with other software. See the :ref:`debops.grub` documentation for more details.
  • The user password storage path in :file:`secret/` directory has been changed to use the inventory_hostname variable instead of the ansible_fqdn variable. This change will force regeneration of password hashes in existing installations, but shouldn't affect host access (passwords stay the same).

:ref:`debops.gunicorn` role

  • The role depends on :ref:`debops.python` now to install the required packages. Please update your custom playbooks accordingly.

:ref:`debops.ipxe` role

  • The role will no longer install non-free firmware by default. This is done to solve the connectivity issues with cdimage.debian.org host.

:ref:`debops.librenms` role

:ref:`debops.lxc` role

  • The role will configure the default subUIDs and subGIDs for unprivileged LXC containers based on the configured subordinate UID/GID ranges for the root account.
  • The :command:`lxc-prepare-ssh` script will now install SSH public keys from the user account that is running the script via :command:`sudo` instead of the system's root account, which is usually what you want to do if other people manage their own LXC containers on a host.
  • The LXC configuration managed by the role will use the :command:`systemd` lxc@.service instances to manage the containers instead of using the :command:`lxc-*` commands directly. This allows the containers to be shut down properly without hitting a timeout and forced killing of container processes.

:ref:`debops.owncloud` role

  • The role will now use Ansible facts managed by the :ref:`debops.redis_server` role to configure Redis support.
  • Drop support for Nextcloud 12.0 which is EOF. Add support for Nextcloud 14.0 and 15.0 and make Nextcloud 14.0 the default Nextcloud version.

:ref:`debops.netbase` role

  • The hostname and domain configuration during bootstrapping is now done by the :ref:`debops.netbase` Ansible role. The default for this role is to remove the 127.0.1.1 host entry from the :file:`/etc/hosts` file to ensure that domain resolution relies on DNS.

    If you are using local domain configured in :file:`/etc/hosts` file, you should define the :envvar:`netbase__domain` variable in the Ansible inventory with your desired domain.

  • The role is redesigned to use list variables instead of YAML dictionaries for the :file:`/etc/hosts` database. This allows for adding the host IPv4 and/or IPv6 addresses defined by Ansible facts when the custom local domain is enabled. See :ref:`netbase__ref_hosts` for details. The role has also been included in the common.yml playbook to ensure that the host database is up to date as soon as possible.

:ref:`debops.resources` role

  • Changed behaviour of used groups for templating. Now all groups the host is in, will be used to search for template files. Read the documentation about :ref:`resources__ref_templates` for more details on templating with debops.

Fixed

:ref:`debops.grub` role

  • The role should now correctly revert custom patch to allow user authentication in :file:`/etc/grub.d/10_linux` script, when the user list is empty.

:ref:`debops.kmod` role

  • The role should now work correctly in Ansible --check mode before the Ansible local fact script is installed.

:ref:`debops.sysctl` role

  • The role should correctly handle nested lists in role dependent variables, which are now flattened before being passed to the configuration filter.

Removed

Roles removed from DebOps

  • The old debops.redis Ansible role has been removed. It has been replaced by the :ref:`debops.redis_server` and :ref:`debops.redis_sentinel` Ansible roles. The new roles use their own Ansible inventory groups, therefore they will need to be explicitly enabled to affect existing hosts.

    You can use the :ref:`debops.debops_legacy` Ansible role to clean up old configuration files, directories and diversions of debops.redis role from remote hosts.

General

  • The ldap_entry and ldap_attr Ansible modules have been removed. They are now included in Ansible core, there's no need to keep a separate copy in the playbook.

:ref:`debops.core` role

  • The ansible_local.root.flags and ansible_local.root.uuid local facts have been removed. They are replaced by ansible_local.tags and ansible_local.uuid local facts, respectively.

:ref:`debops.dhcpd` role

:ref:`debops.ferm` role

:ref:`debops.netbase` role

  • The hostname and domain configuration has been removed from the debops.bootstrap role. This functionality is now handled by the :ref:`debops.netbase` role, which has been included in the bootstrap playbook. The relevant inventory variables have been renamed, check the :ref:`upgrade_notes` for details.

:ref:`debops.resources` role

  • The resources__group_name variable has been removed in favor of using all the groups the current hosts is in. This change has been reflected in the updated variable resources__group_templates.

debops v0.8.0 - 2018-08-06

Added

New DebOps roles

General

  • The DebOps installation now depends on the dnspython Python library. This allows usage of the dig Ansible lookup plugin in DebOps roles to gather data via DNS SRV records.
  • The DebOps installation now depends on the future Python library which provides compatibility between Python 2.7 and Python 3.x environments. It is currently used in the custom Ansible filter plugin provided by DebOps, but its use will be extended to other scripts in the future to make the code more readable.

:ref:`debops.dhparam` role

  • The role will set up a :command:`systemd` timer to regenerate Diffie-Hellman parameters periodically if it's available. The timer will use random delay time, up to 12h, to help with mass DHparam generation in multiple LXC containers/VMs.

:ref:`debops.nginx` role

:ref:`debops.ntp` role

  • The OpenNTPD service will now properly integrate the :command:`ifupdown` hook script with :command:`systemd`. During boot, NTP daemon will be started once network interfaces are configured and will not restart multiple times on each network interface change.

:ref:`debops.resources` role

:ref:`debops.sudo` role

:ref:`debops.users` role

  • Selected UNIX accounts can now be configured to linger when not logged in via the item.linger parameter. This allows these accounts to maintain long-running services when not logged in via their own private :command:`systemd` instances.

Changed

General

  • Some of the existing DebOps Policies and Guidelines have been reorganized and the concept of DebOps Enhancement Proposals (DEPs) is introduced, inspired by the Python Enhancement Proposals.
  • The :command:`debops` script can now parse multiple playbook names specified in any order instead of just looking at the first argument passed to it.

:ref:`debops.apt_install` role

:ref:`debops.apt_mark` role

  • The configuration of automatic removal of APT packages installed via Recommends: or Suggests: dependencies has been moved from the :ref:`debops.apt` role to the :ref:`debops.apt_mark` role which more closely reflects its intended purpose. Variable names and their default values changed; see the :ref:`upgrade_notes` for more details.

:ref:`debops.core` role

  • The role will add any new administrator accounts to the list of existing admin accounts instead of replacing them in the Ansible local fact script. This should allow for multiple administrators to easily coexist and run the DebOps playbooks/roles from their own accounts without issues.

:ref:`debops.gitlab` role

  • Redesign the GitLab version management to read the versions of various components from the GitLab repository files instead of managing them manually in a YAML dictionary. The new :envvar:`gitlab__release` variable is used to specify desired GitLab version to install/manage.
  • The :command:`gitaly` service will be installed using the git UNIX account instead of root. Existing installations might require additional manual cleanup; see the :ref:`upgrade_notes` for details.
  • The role now supports installation of GitLab 10.7.
  • The usage of :envvar:`gitlab__fqdn` variable is revamped a bit - it's now used as the main variable that defines the GitLab installation FQDN. You might need to update the Ansible inventory if you changed the value of the gitlab_domain variable used previously for this purpose.

:ref:`debops.ifupdown` role

:ref:`debops.lxc` role

  • Redesign system-wide LXC configuration to use list of YAML dictionaries merged together instead of custom Jinja templates.
  • Add :command:`lxc-prepare-ssh` script on the LXC hosts that can be used to install OpenSSH and add the user's SSH authorized keys inside of the LXC containers. This is a new way to prepare the LXC containers for Ansible/DebOps management that doesn't require custom LXC template scripts and can be used with different LXC container types.

:ref:`debops.mariadb_server` role

  • The MariaDB/MySQL server and :ref:`client <debops.mariadb>` will now use the utf8mb4 encoding by default instead of the utf8 which is an internal MySQL character encoding. This might impact existing databases, see the :ref:`upgrade_notes` for details.

:ref:`debops.nodejs` role

  • The NPM version installed by the role from GitHub is changed from v5.4.2 to latest which seems to be an equivalent of a stable branch.

  • Recent versions of NPM require NodeJS 6.0.0+ and don't work with other releases. Because of that the newest NPM release is not installable on hosts that use NodeJS packages from older OS releases.

    The :ref:`debops.nodejs` role will install NPM v5.10.0 version in this case to allow NPM to work correctly - on Debian Jessie, Stretch and Ubuntu Xenial. Otherwise, a NPM from the latest branch will be installed, as before.

  • Instead of NodeJS 6.x release, the role will now install NodeJS 8.x release upstream APT packages by default. This is due to the NodeJS 6.x release switching to a Maintenance LTS mode. NodeJS 8.x will be supported as a LTS release until April 2019.

  • The role will install upstream NodeSource APT packages by default. This is due to no security support in Debian Stable, therefore an upstream packages should be considered more secure. The upstream NodeJS packages include a compatible NPM release, therefore it won't be separately installed from GitHub.

    The existing installations shouldn't be affected, since the role will select OS/upstream package versions based on existing Ansible local facts.

:ref:`debops.owncloud` role

  • Support Nextcloud 13 and partially ownCloud 10. Nextcloud 11 and ownCloud 9.1 are EOL, you should update. The role can help you with the update to ensure that everything works smoothly with the new versions. Currently, the role can not do the update for you.

:ref:`debops.sshd` role

  • The role will now check the :ref:`debops.system_groups` Ansible local facts to define what UNIX groups are allowed to connect to the host via the SSH service.

:ref:`debops.unattended_upgrades` role

  • On hosts without a domain set, the role enabled all upgrades, not just security updates. This will not happen anymore, the security updates are enabled everywhere by default, you need to enable all upgrades specifically via the :envvar:`unattended_upgrades__release` variable.

Removed

:ref:`debops.apt_install` role

  • Don't install the sudo package by default, this is now done via a separate :ref:`debops.sudo` role to easily support switching to the sudo-ldap APT package.

:ref:`debops.auth` role

  • Remove configuration of UNIX system groups and accounts in the admins UNIX group. This is now done by the :ref:`debops.system_groups` Ansible role.

debops.console role

debops.bootstrap role

  • The :command:`sudo` configuration has been removed from the debops.bootstrap role. The bootstrap.yml playbook now includes the :ref:`debops.sudo` role which configures :command:`sudo` service.
  • The UNIX system group management has been removed from the role, the bootstrap.yml playbook now uses the :ref:`debops.system_groups` role to create the UNIX groups used by DebOps during bootstrapping.
  • Remove management of Python packages from the role. The bootstrap.yml playbook uses the :ref:`debops.python` role to configure Python support on the host.

:ref:`debops.lxc` role

  • Remove support for direct LXC container management from the role. This functionality is better suited for other tools like :command:`lxc-*` set of commands, or the Ansible lxc_container module which should be used in custom playbooks. The 'debops.lxc' role focus should be configuration of LXC support on a host.
  • Remove custom LXC template support. The LXC containers can be created by the normal templates provided by the lxc package, and then configured using DebOps roles as usual.

:ref:`debops.postgresql_server` role

  • The tasks that modified the default template1 database and its schema have been removed to make the PostgreSQL installation more compatible with applications packaged in Debian that rely on the PostgreSQL service. See the relevant commit for more details. Existing installations shouldn't be affected.

debops v0.7.2 - 2018-03-28

Fixed

General

  • Add missing python-ldap dependency as an APT package in the Dockerfile.

debops v0.7.1 - 2018-03-28

Added

New DebOps roles

  • The :ref:`debops.ansible` role: install Ansible on a Debian/Ubuntu host using Ansible. The `debops.debops role now uses the new role to install Ansible instead of doing it directly.
  • The :ref:`debops.apt_mark` role: set install state of APT packages (manual/auto) or specify that particular packages should be held in their current state. The role is included in the common.yml playbook.
  • The :ref:`debops.kmod` role: manage kernel module configuration and module loading at boot time. This role replaces the debops-contrib.kernel_module role.
  • The debops-contrib.etckeeper role has been integrated into DebOps as :ref:`debops.etckeeper`. The new role is included in the common.yml playbook.

:ref:`debops.ifupdown` role

Changed

Continuous Integration

:ref:`debops.etherpad` role

  • The role can now autodetect and use a PostgreSQL database as a backend database for Etherpad.

:ref:`debops.ferm` role

  • The role should now correctly detect what Internet Protocols are available on a host (IPv4, IPv6) and configure firewall only for the protocols that are present.

:ref:`debops.lxc` role

  • The role will now generate the lxc-debops LXC template script from different templates, based on an OS release. This change should help fix the issues with LXC container creation on Debian Stretch.

:ref:`debops.pki` role

  • The X.509 certificate included in the default domain PKI realm will now have a SubjectAltName wildcard entry for the host's FQDN. This should allow for easy usage of services related to a particular host in the cluster over encrypted connections, for example host monitoring, service discovery, etc. which can be now published in the DNS zone at *.host.example.org resource records.
  • The role now supports Let's Encrypt ACMEv2 API via the acme-tiny Python script. The existing PKI realms will need to be re-created or updated for the new API to work, new PKI realms should work out of the box. Check the :ref:`upgrade_notes` for more details.

:ref:`debops.proc_hidepid` role

  • The role now uses a static GID 70 for the procadmins group to synchronize the access permissions on a host and inside the LXC containers. You will need to remount the filesystems, restart services and LXC containers that rely on this functionality.

:ref:`debops.sysctl` role

  • The configuration of the kernel parameters has been redesigned, instead of being based on YAML dictionaries, is now based on YAML lists of dictionaries and can be easily changed via Ansible inventory. You will need to update your inventory for the new changes to take effect, refer to the :ref:`role documentation <sysctl__ref_parameters>` for details.

Fixed

General

:ref:`debops.nginx` role

  • Fix a long standing bug in the role with Ansible failing during welcome page template generation with Jinja2 >= 2.9.4. It was related to non-backwards compatible change in Jinja that modified how variables are processed in a loop.

Removed

Roles removed from DebOps

  • The debops-contrib.kernel_module Ansible role has been removed; it was replaced by the new :ref:`debops.kmod` Ansible role.

:ref:`debops.ferm` role

  • The ferm-forward hook script in the :file:`/etc/network/if-pre-up.d/` directory has been removed (existing instances will be cleaned up). Recent changes in the :ref:`debops.ferm` role broke idempotency with the :ref:`debops.ifupdown` role, and it was determined that the functionality provided by the hook is no longer needed, recent OS releases should deal with it adequately.

debops v0.7.0 - 2018-02-11

Added

New DebOps roles

  • New Ansible roles have been imported from the debops-contrib organization: apparmor, bitcoind, btrfs, dropbear_initramfs, etckeeper, firejail, foodsoft, fuse, homeassistant, kernel_module, kodi, neurodebian, snapshot_snapper, tor, volkszaehler, x2go_server. They are not yet included in the main playbook and still need to be renamed to fit with the rest of the debops.* roles.
  • The :ref:`debops.sysfs` role: configuration of the Linux kernel attributes through the :file:`/sys` filesystem. The role is not enabled by default.
  • The :ref:`debops.locales` role: configure localization and internationalization on a given host or set of hosts.
  • The :ref:`debops.machine` role: manage the :file:`/etc/machine-info` file, the :file:`/etc/issue` file and a dynamic MOTD.
  • The :ref:`debops.proc_hidepid` role: configure the /proc hidepid= options.
  • The :ref:`debops.roundcube` role: manage RoundCube Webmail application.
  • The :ref:`debops.prosody` role: configure an xmpp server on a given host.
  • The :ref:`debops.sysnews` role: manage System News bulletin for UNIX accounts.

Continuous Integration

  • DebOps roles and playbooks can now be tested using local or remote GitLab CI instance, with Vagrant, KVM and LXC technologies and some custom scripts.

General

  • You can now :ref:`use Vagrant <quick_start__vagrant>` to create an Ansible Controller based on Debian Stretch and use it to manage itself or other hosts over the network.
  • You can now build an Ansible Controller with DebOps support as a Docker container. :ref:`Official Docker image <quick_start__docker>` is also available, automatically rebuilt on every commit.
  • You can now install DebOps on Arch Linux using an included PKGBUILD file.
  • Add new playbook, agent.yml. This playbook is executed at the end of the main playbook, and contains applications or services which act as "agents" of other services. They may contact their parent applications to report about the state of the host they are executed on, therefore the agents are installed and configured at the end of the main playbook.
  • DebOps roles and playbooks will be included in the Python packages released on PyPI. This will allow for easier installation of DebOps via :command:`pip` (no need to download the roles and playbooks separately) as well as simple stable releases. The DebOps monorepo can still be installed separately.

:ref:`debops.libvirtd` role

  • The role can now detect if nested KVM is enabled in a particular virtual machine and install KVM support.

:ref:`debops.nodejs` role

  • The :ref:`debops.nodejs` role can now install Yarn package manager using its upstream APT repository (not enabled by default).

Changed

Continuous Integration

General

  • The :command:`debops-update` script will now install or update the DebOps monorepo instead of separate debops-playbooks and DebOps roles git repositories. Existing installations shouldn't be affected.

  • The :command:`debops` script will now include the DebOps monorepo roles and playbooks in the generated :file:`ansible.cfg` configuration. The monorepo roles and playbooks are preferred over the old debops-playbooks ones.

    The script is backwards compatible and should work correctly with or without the debops-playbooks repository and roles installed.

  • Improved Python 3 support in the DebOps scripts and throughout the playbooks/roles. DebOps should now be compatible with both Python versions.

:ref:`debops.gitlab_runner` role

  • The GitLab Runner playbook is moved to the agent.yml playbook; it will be executed at the end of the main playbook and should that way include correct information about installed services.

:ref:`debops.gunicorn` role

  • Update the role to work correctly on Debian Stretch and newer releases. The support for multiple :command:`gunicorn` instances using custom Debian scripts has been removed in Debian Stretch, therefore the role replaces it with its own setup based on :command:`systemd` instances.

:ref:`debops.nodejs` role

  • The npm package has been removed from Debian Stable. The role will now install NPM using the GitHub source, unless upstream NodeJS is enabled, which includes its own NPM version.

Removed

debops.console role

  • Remove the locales configuration from the 'debops.console' role, this functionality has been moved to the new 'debops.locales' role. You will need to update the Ansible inventory variables to reflect the changes.

  • Management of the /proc hidepid= option has been moved to a new role, :ref:`debops.proc_hidepid`. You will need to update the Ansible inventory variables to reflect the changes.
