Upgrade notes

This document contains information and notes about any changes that are required in the Ansible inventory or the IT infrastructure managed by DebOps to perform the upgrades between different stable releases.

Unreleased

v3.3.0 (2026-03-13)

No significant changes which require a manual intervention.

v3.2.0 (2024-09-16)

No significant changes which require a manual intervention.

v3.1.0 (2023-11-29)

Changes in inventory variables

v3.0.0 (2022-02-17)

Changes in the OpenLDAP support

  • In the :ref:`debops.slapd` role, the :file:`mailservice.schema` LDAP schema includes two new LDAP attributes, mailPrivateAddress and mailContactAddress. The server will enforce the mailPrivateAddress attribute to be unique and that all its values are also included in the mail attribute.

    The above constraints result in the role not working correctly when the new :file:`mailservice.schema` is not applied in the OpenLDAP service. The role cannot "re-apply" an already installed LDAP schema, therefore the service needs to be rebuilt for the new changes to take effect. Refer to the :ref:`slapd__ref_backup_restore` documentation for help with rebuilding the directory.

Redesign of the Debian Pressed support

  • The :ref:`debops.preseed` role has been redesigned from the ground up. Most of the variables related to :file:`preseed.cfg` and :file:`postinst.sh` file contents have been removed and role now uses :ref:`universal_configuration` system to manage the contents of these files. You should check the new role defaults and documentation to see how Preseed configuration is implemented.
  • Support for installation and configuration of Salt Minions during provisioning has been removed from the :file:`postinst.sh` scripts. Basic installation can be implemented uding postinst commands; if there's a demand for fully-fledged support it can be brought back.
  • Access controls using :ref:`debops.nginx` role access policy functionality has been removed. If needed, access control can be implemented using firewall rules to restrict access to the Preseed server to selected subnets.
  • The role no longer creates separate UNIX group and account for Preseed configuration files published by the webserver. The files are owned by the root UNIX account, with www-data group having read-only access.
  • Location of the generated Preseed files has been changed to conform better to best practices used in DebOps; files will be stored in the :file:`/srv/www/sites/debian-preseed/public/` directory by default.
  • The names of the :command:`nginx` configuration files have been changed; they are no longer based on the DNS domain used by Preseed but use static filenames. In the existing installations, the old configuration files might need to be removed manually to avoid conflicts with new configuration.
  • The :file:`postinst.sh` scripts have been greatly simplified and no longer contain code that creates custom UNIX accounts and configures :command:`grub` directly. These functionalities have been delegated to the Debian Installer and are used through the Preseed configuration files.

Changes in inventory variables

  • In the :ref:`debops.nginx` role one variable was removed:

    Old variable name

    New variable name

    Changed value

    nginx_enable_sdpy

    Removed

    No

Icinga Director database migrations

  • After :ref:`debops.icinga_web` updates the Icinga Director module, you will have to perform a quick database migration to get Director to work again. Just click the database migration button on the 'Icinga Director' -> 'Activities log' page.

v2.3.0 (2021-06-04)

Redesigned authorized_keys role

v2.2.0 (2021-01-31)

Changes in the NetBox role

  • netbox__config_webhooks_enabled has been removed upstream. No further action other than removing the variable from your inventory should be needed. See Require running the rq-worker process.

Changes to debops.resolvconf facts

  • 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.

Splitting up debops.dhcpd

Changes in the OpenLDAP support

  • The list of the OpenLDAP overlays configured by the :ref:`debops.slapd` role has been modified. This change cannot be applied cleanly on an existing OpenLDAP server and will require re-initialization of the service - an easiest way is reinstallation of the host and import of the existing directory. Check the :ref:`slapd__ref_backup_restore` documentation for more details and restore instructions.

  • The :file:`mailservice.schema` and the :file:`eduperson.schema` LDAP schemas have been modified. Changes will not be applied automatically on existing installations and it is recommended to re-create the directory from scratch to apply new schema cleanly.

  • Some variables in the :ref:`debops.slapd` role have been modified:

    Old variable name

    New variable name

    Changed value

    slapd__slapacl_test_rdn_map

    :envvar:`slapd__slapacl_default_tasks`

    Yes, a list

ISC DHCP Server role rewrite

Changes in :ref:`debops.lvm`

  • Changed default behaviour: the role now mounts LVM volumes even when item.fs is not defined. This of course still requires setting the mount point with item.mount.

v2.1.0 (2020-06-21)

Inventory variable changes

v2.0.0 (2020-01-30)

General

  • Official DebOps roles have been renamed and the debops. prefix has been dropped from the directory names. The custom playbooks and role dependencies that use DebOps roles will have to be updated accordingly to function correctly again.

  • The variables in various roles that hold the automatically generated passwords stored in the :file:`secret/` directory have been modified to use the inventory_hostname variable instead of the ansible_fqdn variable as a part of the path to the password file. The roles where these changes happened are:

    These changes will result in existing passwords or other generated data being automatically regenerated by Ansible on the next run of a given role. This might affect access to the services from other hosts if the new passwords are not applied everywhere. Make sure to re-run the affected roles on all relevant hosts in your infrastructure to update the passwords where necessary.

LDAP

  • The values of the authorizedService and host LDAP attributes expected by various DebOps roles have been changed. You will need to update your LDAP directory entries for the new values to take effect before applying these changes to the remote hosts, otherwise users and services might stop working correctly.

    Changes in the authorizedService attribute:

    Old value

    New value

    Notes

    *

    all

    Grants access to all services

    web-public

    web:public

    Grants access to publicly-reachable web services

    None

    shell

    Grants access to UNIX environment over SSH protocol

    Changes in the host attribute:

    Old value

    New value

    Notes

    *

    posix:all

    Grants access to POSIX environment on all hosts

    <fqdn>

    posix:<fqdn>

    Grants access to POSIX environment on a specific host based on its FQDN

    *.<domain>

    posix:*.<domain>

    Grants access to POSIX environment on a specific host based on its domain

    <hostname>

    Removed

    This scheme has been replaced by a more general purpose "URN-like" scheme. See :ref:`ldap__ref_ldap_access_host` for more details.

Inventory variable changes

  • Some variables in the :ref:`debops.docker_server` role have been renamed:

    Old variable name

    New variable name

    Changed value

    docker_server__graph

    docker_server__data_root

    No

  • A few of the default variables in the :ref:`debops.dovecot` role have been renamed. Additionally some variables related to the Sieve plugin configuration also changed:

    Old variable name

    New variable name

    Changed value

    dovecot_ssl_protocols

    dovecot_ssl_min_protocol

    No

    dovecot_firewall

    Removed, see "Firewall configuration"

    No

    dovecot_mail_location

    dovecot_mail_location

    Yes

    dovecot_sieve

    dovecot_sieve_active_script

    No

    dovecot_managesieve_config_map

    dovecot_managesieve_config_map

    Yes

    dovecot_lda_config_map

    dovecot_lda_config_map

    Yes

  • Some of the variables in the :ref:`debops.roundcube` role have been renamed:

    Old variable name

    New variable name

    Changed value

    roundcube__default_host

    :envvar:`roundcube__imap_server`

    No

    roundcube__domain

    :envvar:`roundcube__fqdn`

    Yes, a string

    roundcube__local_config_map

    :envvar:`roundcube__configuration`

    Yes

    roundcube__group_local_config_map

    :envvar:`roundcube__group_configuration`

    Yes

    roundcube__host_local_config_map

    :envvar:`roundcube__host_configuration`

    Yes

    roundcube__git_dest

    :envvar:`roundcube__git_dir`

    No

    roundcube__git_checkout

    :envvar:`roundcube__git_dest`

    No

    :envvar:`roundcube__default_plugins`

    The same

    Yes, check variable

    Due to the change in the installation method, the Roundcube installation needs to be done from scratch. Before the role can work correctly, you should remove (or move aside) the source and installation directories. In the default setup you can run on a host:

    rm -rf /srv/www/sites/roundcube/public /usr/local/src/roundcube

    This will remove the installation and source directories, after which the role should be able to install Roundcube without issues. Remember to create backups in case of errors, especially if you use the SQLite database as backend since by default it is located inside of the installation directory.

v1.2.0 (2019-12-01)

Role configuration changes

  • In the :ref:`debops.dnsmasq` role, :ref:`dnsmasq__ref_interfaces` variable configuration, the router_enabled parameter has been renamed to the router_state parameter, with changed value type.
  • In the :ref:`debops.golang` role, the golang__*_packages variables are used to define Go packages instead of simple list of APT packages, with entirely new syntax. Existing roles that rely on these variables might need to be updated. See the :ref:`golang__ref_packages` documentation for more details.

Inventory variable changes

v1.1.0 (2019-08-25)

GPG key management changes

The :ref:`debops.keyring` centralizes management of the APT keyring and various GPG keyrings in unprivileged UNIX accounts. Various DebOps roles have been modified to use this role instead of performing the GPG key management on their own. If you use custom Ansible playbooks with these roles, you will need to update them to include the :ref:`debops.keyring` role.

List of modified DebOps roles:

NodeJS and NPM changes

  • By default, the :ref:`debops.nodejs` role will install the NodeJS and NPM packages from the OS (Debian or Ubuntu) repositories. On the Debian Oldstable release (currently Stretch), the packages backported from the Stable release will be used. The role supports an automatic upgrade to the upstream NodeJS package when the support for NodeSource repositories is enabled using the :envvar:`nodejs__node_upstream` variable.

    On existing installations, status of the upstream APT repository should be preserved, however note that the Ansible local fact name that tracks this has been changed to ansible_local.nodejs.node_upstream, along with the default variable name. You might want to update the Ansible inventory to reflect the desired status of the NodeJS and NPM upstream support.

Inventory variable changes

  • The :ref:`debops.rsnapshot` role has been redesigned and all of its rsnapshot_* variables have been renamed to rsnapshot__* to contain them in their own namespace. You will have to update your inventory.

    The configuration of the hosts to back up has also been redesigned; the role does not use Ansible inventory groups to define the hosts to back up implicitly; you now have to explicitly specify hosts to back up using the :ref:`rsnapshot__ref_hosts` variables. There is a way to replicate the previous usage of inventory groups to define hosts to back up as well, see the provided examples.

  • The debops.docker role has been renamed to :ref:`debops.docker_server`. The docker__* variables have been renamed to docker_server__*. You will have to update your inventory variables and move all hosts to the new inventory group [debops_service_docker_server] to continue using this role.

    Also, the Docker server no longer listens on a TCP port by default, even if :ref:`debops.pki` is enabled. You must set docker_server__tcp to True and configure an IP address whitelist in docker_server__tcp_allow if you want to connect to the Docker server over a network. It is recommended to use :ref:`debops.pki` to secure the connection with TLS.

  • The :ref:`debops.lxc` role uses different names of the container configuration options depending on the LXC version used on the host. The name parameters used in the configuration might change unexpectedly between LXC versions, which might lead to wrong configuration entries being merged and broken LXC configuration.

    If you have configured :ref:`lxc__ref_configuration` variables in the Ansible inventory, review them before applying the role configuration on LXC hosts. You can check the :envvar:`lxc__default_configuration` variable to see which name parameters can change.

  • The lxc__net_interface_fqdn variable has been renamed to :envvar:`lxc__net_fqdn` to conform to the variable naming scheme for domain and FQDN names used in different DebOps roles. The new variable defines the FQDN name of the lxcbr0 interface. The :envvar:`lxc__net_domain` variable which has done that previously is now used to define the DNS domain for the internal LXC subnet, and the new :envvar:`lxc__net_base_domain` variable defines the base DNS domain for the lxc. subdomain.

  • The :ref:`debops.ipxe` role default variables have been renamed to move them to their own ipxe__* namespace; you will have to update the Ansible inventory.

  • The core__keyserver variable and its corresponding local fact have been replaced by the :envvar:`keyring__keyserver` with a corresponding local fact.

  • The :ref:`debops.nginx` role no longer defaults to limiting the allowed HTTP request methods to GET, HEAD and POST on PHP-enabled websites. Use the item.php_limit_except parameter if you want to keep limiting the request methods.

  • The nodejs__upstream* variables in the :ref:`debops.nodejs` role have been renamed to nodejs__node_upstream* to better indicate their purpose and differentiate them from the nodejs__yarn_upstream* variables.

  • The dokuwiki__main_domain variable has been renamed to :envvar:`dokuwiki__fqdn` to fit the naming scheme in other DebOps roles.

v1.0.0 (2019-05-22)

Redesigned OpenLDAP support

  • The :ref:`debops.slapd` role has been redesigned from the ground up, everything is new. Existing OpenLDAP servers/clusters will break if the new role is applied on them, don't do it. Set up a new OpenLDAP server/cluster and import the LDAP directory afterwards. See the role documentation for more details.

Changes to the UNIX group and account management

  • The :ref:`debops.users` Ansible role has been modernized and it now uses the custom Ansible filter plugins included in DebOps to manage the UNIX groups and accounts. The group and account management now uses the same merged list of entries, which means that two new parameters have been added to control when groups or accounts are created/removed. You might need to update your inventory configuration if you use the role to create UNIX groups without corresponding accounts, or you put UNIX accounts in shared primary groups.

    By default, :ref:`debops.users` will create user private groups if item.group parameter is not specified; if you want to add accounts to the users primary group, you need to specify it explicitly.

    The user parameter can be used to disable the account management, so that only UNIX group is created. The private_group parameter controls the management of the UNIX group for a given configuration entry. See the role documentation for more details.

  • The users__default_system variable has been removed from the :ref:`debops.users` role. The UNIX groups and accounts created by the role on hosts with the LDAP support will be normal accounts, not "system" accounts, and will use UID/GID >= 1000. This can be controlled per-user/per-group using the item.system parameter.

  • The item.createhome parameter has been renamed to item.create_home in accordance with the renamed parameter of the user Ansible module.

  • The users__resources, users__group_resources and users__host_resources variables have been removed. Their functionality has been reimplemented as the item.resources parameter of the users__*_accounts variables. See the role documentation for more details.

  • The management of the admin accounts has been removed from the :ref:`debops.users` role and is now done in the :ref:`debops.system_users` role. See the :envvar:`system_users__default_accounts` for a list of the default admin accounts created on the remote hosts.

Inventory variable changes

v0.8.1 (2019-02-02)

Subordinate UID/GID ranges for root

  • The :ref:`debops.root_account` role will register a set of UID/GID ranges for the root account in the :file:`/etc/subuid` and :file:`/etc/subgid` databases. Depending on the OS distribution and release, these databases might contain existing UID/GID ranges which might interfere with the default set of 100000-165536 UID/GID range selected for the root account.

    In that case you should either disable this functionality, or recreate the host, at which point the UID/GID ranges for root will be reserved first, and any new accounts created by the system will use subsequent UIDs/GIDs. You can also update the UID/GID ranges manually, or select different UID/GID ranges for the root account in the role defaults.

Changes to Redis support in GitLab

  • The Redis support has been removed from the :ref:`debops.gitlab` playbook. Since GitLab still requires Redis to work properly, you need to enable :ref:`debops.redis_server` role explicitly for the GitLab host. GitLab installation instructions have been updated to reflect this fact.
  • To manage Redis on existing GitLab installations, you should enable the :ref:`debops.redis_server` role on them and run the Redis and GitLab playbooks afterwards. The existing Redis instance will be stopped and new Redis instance will be set up, with the same TCP port and password. Since the database will be empty, Gitaly service might stop working. After running the Redis Server and GitLab playbooks, restart the entire GitLab slice to re-populate Redis. You might expect existing GitLab sessions to be invalid and users to have to log in again.
  • The :ref:`debops.redis_server` role will configure APT preferences on Debian Stretch to install Redis from the stretch-backports repository. The playbook run on existing installations will not upgrade the packages automatically, but you might expect it on normal system upgrade.

Changes related to packet forwarding in firewall and sysctl

  • The :ref:`debops.ifupdown` role now uses :ref:`debops.sysctl` role directly as a dependency to generate forwarding configuration for each managed network interface that has it enabled. This might impact packet forwarding on existing systems; run the role with Ansible --diff --check options first to review the planned changes to the host.

  • The :ref:`debops.ferm` role will no longer enable packet forwarding on all network interfaces. Existing :file:`/etc/sysctl.d/30-ferm.conf` configuration file can be removed using the :ref:`debops.debops_legacy` role.

    The :ref:`debops.ferm` role will remove firewall rules that enabled forwarding between "external" and "internal" network interfaces, named forward_external_in, forward_external_out and forward_internal. They are redundant with the similar firewall rules generated by the :ref:`debops.ifupdown` role and their removal shouldn't impact connectivity, however you should check the modifications to the firewall just in case.

Redesigned DNSmasq support

  • The :ref:`debops.dnsmasq` role has been redesigned from the ground up. The configuration is now merged from multiple sources (role defaults, Ansible inventory), role defines separate subdomains for each of the network interfaces, and automatically enables support for local Consul DNS service or LXC subdomain if they are detected on the host.
  • Most of the dnsmasq__* default variables that defined the :command:`dnsmasq` configuration have been removed. Their functionality is exposed either as parameters of network interface configuration, or can be easily changed via the main configuration pipeline. See the documentation of :ref:`dnsmasq__ref_configuration` or :ref:`dnsmasq__ref_interfaces` for more details. If you use DNSmasq on a host managed by DebOps, you will have to modify your Ansible inventory.
  • The generated :command:`dnsmasq` configuration has been split from a single 00_main.conf configuration file into multiple separate files stored in the :file:`/etc/dnsmasq.d/` directory. The old 00_main.conf configuration file will be automatically removed if found, to avoid issues with duplicated configuration options.
  • The role provides an easy to use way to define DHCP clients with IP address reservation, as well as DNS resource records. See :ref:`dnsmasq__ref_dhcp_dns_entries` documentation for examples and more details.
  • The configuration of TCP Wrappers for the TFTP service has been removed from the :ref:`debops.dnsmasq` role, and is now done via the :ref:`debops.tcpwrappers` Ansible role and its dependent variables.

Inventory variable changes

  • The :ref:`debops.grub` role was redesigned, most of the grub_* default variables have been removed and the new configuration method has been implemented. The role variables have been namespaced, the role now uses grub__* variable naming scheme. Check the role documentation for details about configuring GRUB via Ansible inventory.

  • Variables related to :command:`dhcp_probe` in the :ref:`debops.dhcpd` role have been replaced with the variables from the :ref:`debops.dhcp_probe` role. They are now namespaced and mostly with the same value types.

    The new :ref:`debops.dhcp_probe` role utilizes :command:`systemd` templated instances, and might not work correctly on older Debian/Ubuntu releases.

  • The variables related to packet forwarding in the :ref:`debops.ferm` role and related roles have been removed:

    • ferm__forward
    • ferm__forward_accept
    • ferm__external_interfaces
    • ferm__internal_interfaces
    • libvirtd__ferm__forward
    • lxc__ferm__forward

    The related Ansible local fact ansible_local.ferm.forward has also been removed.

    You can use the :ref:`debops.ifupdown` role to configure packet forwarding per network interface, in the firewall as well as via the kernel parameters.

  • Host and domain management has been removed from the debops.bootstrap role. This functionality is now done via the :ref:`debops.netbase` role, included in the bootstrap playbook. Some of the old variables have their new equivalents:

    Old variable name

    New variable name

    Changed value

    bootstrap__hostname_domain_config_enabled

    :envvar:`netbase__hostname_config_enabled`

    No

    bootstrap__hostname

    :envvar:`netbase__hostname`

    No

    bootstrap__domain

    :envvar:`netbase__domain`

    No

    bootstrap__etc_hosts

    Removed

    No

    bootstrap__hostname_v6_loopback

    Removed

    No

    Support for configuring IPv6 loopback address has been removed entirely. This was required when some of the DebOps roles relied on the ansible_fqdn value for task delegation between hosts. Since then, task delegation has been updated to use the inventory_hostname values and ensuring that the IPv6 loopback address resolves to a FQDN address of the host is no longer required.

  • The netbase__*_hosts variables in the :ref:`debops.netbase` role have been redesigned to use YAML lists instead of dictionaries. See :ref:`netbase__ref_hosts` for more details.

  • 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 :envvar:`resources__group_templates`. If you need to use a specific group update the :envvar:`resources__group_templates` accordingly. Read the documentation about :ref:`resources__ref_templates` for more details on templating with debops.resources.

Changes related to LXC containers

  • The :ref:`debops.lxc` role will configure new LXC containers to attach to the lxcbr0 bridge by default. Existing LXC containers will not be modified. You can change the default bridge used on container creation using the :ref:`lxc__ref_configuration` variables.

  • The :ref:`debops.lxc` role has been updated to use the :command:`systemd` lxc@.service instances to manage the containers instead of using the :command:`lxc-*` commands directly. Existing LXC containers should not be affected, but it is recommended to switch them under the :command:`systemd` control. To do that, you should disable the container autostart in the :file:`/var/lib/lxc/<container>/config` configuration files:

    lxc.start.auto = 0

    This will make sure that the containers are not started by the lxc.service service on boot. Next, after stopping the running containers, enable and start the containers via the :command:`systemd` instance:

    systemctl enable lxc@<container>.service
systemctl start lxc@<container>.service

    This should ensure that the containers are properly shut down and started with the host system.

v0.8.0 (2018-08-06)

UNIX account and group configuration

GitLab :command:`gitaly` installation

  • The :ref:`debops.gitlab` role will now build and install the :command:`gitaly` service using unprivileged git UNIX account instead of root. To perform the update correctly, you might need to remove directories

    /usr/local/src/gitlab/gitlab.com/gitaly.git/
/var/local/git/gitaly/

    Some files in these directories are owned by root and that can prevent the correct build of the Go binaries. You might also want to stop the gitlab-gitaly.service service and start it afterwards.

    The above steps shouldn't impact new GitLab installations.

UTF8 encoding in MariaDB

Inventory variable changes

  • The console_preferred_editors list has been removed, configuration of the preferred :command:`vim` editor is now done in the :ref:`debops.apt_install` role which also installs it.

  • The console_custom_files variable has been removed along with the functionality in debops.console role. Use the :ref:`debops.resources` role variables to copy custom files instead. The role is also included in the common playbook, although a bit earlier, which shouldn't impact normal use cases.

  • The management of the :file:`/etc/hosts` file has been removed from the debops.console role and is now done via the :ref:`debops.netbase` role which has to be enabled through the Ansible inventory. The variables have been renamed:

    Old variable name

    New variable name

    Changed value

    console_hosts

    :envvar:`netbase__hosts`

    No

    console_group_hosts

    :envvar:`netbase__group_hosts`

    No

    console_host_hosts

    :envvar:`netbase__host_hosts`

    No

  • Configuration of the APT autoremove options has been moved from the :ref:`debops.apt` role to the :ref:`debops.apt_mark` role, because the latter role has more specific scope. The variable names as well as their default values have been changed to correctly reflect the meaning of the corresponding APT configuration options:

    Old variable name

    New variable name

    Changed value

    apt__autoremove_recommends

    :envvar:`apt_mark__autoremove_recommends_important`

    Yes, to True

    apt__autoremove_suggests

    :envvar:`apt_mark__autoremove_suggests_important`

    Yes, to True

    By default the APT packages installed via Recommends or Suggests dependencies will not be considered for autoremoval. If the user sets any package configuration via :ref:`debops.apt_mark` role, the autoremoval will be enabled automatically.

  • The bootstrap__sudo and bootstrap__sudo_group variables have been removed from the debops.bootstrap role. The bootstrap.yml playbook now uses the :ref:`debops.sudo` role to configure :command:`sudo` service on a host, use its variables instead to control the service in question.

  • The bootstrap__admin_groups variable will now use list of UNIX groups with root access defined by the :ref:`debops.system_groups` via Ansible local facts.

  • The contents of the sshd__allow_groups variable have been moved to the new sshd__default_allow_groups variable. The new variable also uses the :ref:`debops.system_groups` Ansible local facts as a data source.

  • The bootstrap__raw and bootstrap__mandatory_packages variables have been removed. See the :ref:`debops.python` role documentation for their equivalents.

  • The apt_install__python_packages variable has been removed from the :ref:`debops.apt_install` role. Use the :ref:`debops.python` Ansible role to install Python packages.

  • The nodejs__upstream_version variable has been renamed to :envvar:`nodejs__node_upstream_release` to better represent the contents, which is not a specific NodeJS version, but a specific major release.

  • The gitlab_domain variable, previously used to set the FQDN of the GitLab installation, now only sets the domain part; it's value is also changed from a YAML list to a string.

    The :envvar:`gitlab__fqdn` variable is now used to set the GitLab FQDN and uses the gitlab_domain value as the domain part.

v0.7.2 (2018-03-28)

No changes.

v0.7.1 (2018-03-28)

X.509 certificate changes

  • The :ref:`debops.pki` role now generates the default X.509 certificate for the domain PKI realm with a wildcard entry for the host's FQDN (for example, *.host.example.org). This will be true by default on new hosts introduced to the cluster; if you want your old hosts to have the new X.509 certificates, you need to recreate the domain PKI realm by removing the :file:`/etc/pki/realms/domain/` directory on the remote hosts and re-running the :ref:`debops.pki` role against them.

    The change is done in the :envvar:`pki_default_realms` variable, if you redefined it in the Ansible inventory, you might want to update your version to include the new SubjectAltName entry.

  • The latest :program:`acme-tiny` Python script uses ACMEv2 API by default, and the :ref:`debops.pki` role is now compatible with the upstream changes. The ACME certificates should work out of the box in new PKI realms, after the :program:`acme-tiny` installation is updated.

    The existing PKI realms will stop correctly regenerating Let's Encrypt certificates, because their configuration is not updated automatically by the role. The presence of the :file:`acme/error.log` file will prevent the :program:`acme-tiny` script from requesting the certificates to not trip the Let's Encrypt rate limits.

    Easiest way to fix this is to remove the entire PKI realm (:file:`/etc/pki/realms/*/` directory) and re-run the :ref:`debops.pki` role against the host. The role will create a new PKI realm based on the previous configuration and ACME certificates should start working again. Services like :program:`nginx` that have hooks in the :file:`/etc/pki/hooks/` directory should be restarted automatically, you might need to manually restart other services as needed.

    Alternatively, you can update the Let's Encrypt API URL in the realm's :file:`config/realm.conf` file by replacing the line:

    config['acme_ca_api']='https://acme-v01.api.letsencrypt.org'

    with:

    config['acme_ca_api']='https://acme-v02.api.letsencrypt.org/directory'

    This should tell the :program:`pki-realm` script to send requests for new certificates to the correct URL. You still need to run the :ref:`debops.pki` role against the host to install the updated :program:`pki-realm` script and update the :program:`acme-tiny` script.

Role changes

  • The debops.debops role now uses the :ref:`debops.ansible` role to install Ansible instead of doing it by itself. The relevant code has been removed, see the :ref:`debops.ansible` role documentation for new variables.

  • The debops-contrib.kernel_module role has been replaced by the :ref:`debops.kmod` role. All of the variable names have been changed, as well as their usage. See the documentation of the new role for more details.

  • The :ref:`debops.proc_hidepid` role was modified to use a static GID 70 for the procadmins group to allow synchronization between host and LXC containers on that host. The role will apply changes in the :file:`/etc/fstab` configuration file, but it will not change existing :file:`/proc` mount options. You need to remount the filesystem manually, with a command:

    ansible all -b -m command -a 'mount -o remount /proc'

    The :file:`/proc` filesystem mounted inside of LXC containers cannot be remounted this way, since it's most likely mounted by the host itself. You will need to check the LXC container configuration in the :file:`/var/lib/lxc/*/config` files and update the mount point options to use the new static GID. Restart the LXC container afterwards to remount the :file:`/proc` filesystem.

    You will also need to restart all services that rely on the procadmins group, for example :command:`snmpd`, to activate the new GID.

  • The :ref:`debops.sysctl` configuration has been redesigned. The role now uses YAML lists instead of YAML dictionaries as a base value of the sysctl__*_parameters default variables. The kernel parameter configuration format has also been changed to be easy to override via Ansible inventory. Role can now configure multiple files in :file:`/etc/sysctl.d/` directory. Refer to the role documentation for details.

Inventory variable changes

  • The :ref:`debops.netbox` role has been updated, some variable names were changed:

    Old variable name

    New variable name

    Changed value

    netbox__config_netbox_username

    netbox__config_napalm_username

    No

    netbox__config_netbox_password

    netbox__config_napalm_password

    No

  • The variables that specify files to ignore in the new :ref:`debops.etckeeper` role have been renamed from their old versions in debops-contrib.etckeeper role, and their value format changed as well. See the documentation of the new role for details.

v0.7.0 (2018-02-11)

This is mostly a maintenance release, dedicated to reorganization of the DebOps :command:`git` repository and expanding documentation.

Role changes

  • The :ref:`debops.nodejs` role now installs NPM using a script in upstream :command:`git` repository. This might cause issues with already installed NPM package, because of that it will be automatically removed by the role if found. You should verify that the role behaves correctly on existing systems before applying it in production.
  • The :ref:`debops.gunicorn` role has rewritten configuration model based on :command:`systemd` instanced units. The existing configuration shouldn't interfere, however you might need to update the Ansible inventory configuration variables to the new syntax.

Inventory variable changes

v0.6.0 (2017-10-21)

This is an initial release based off of the previous DebOps roles, playbooks and tools located in separate :command:`git` repositories. There should be no changes needed between the old and the new infrastructure and inventory.
