Ansible Role: Nexus 3 OSS

This role installs and configures Nexus Repository Manager OSS version 3.x.

All configuration can be updated by re-running the role, except for the blobstores related settings, which are immutable in nexus.

History / Credits

This role is a fork of ansible-nexus3-oss by @savoirfairelinux after they announced end of maintenance. You can have a look at the following tickets in the original repository for explanations:

We would like to thank the original authors for the work done.

Requirements

Fairly Up-to-date version of ansible. We follow ansible versions during maintenance/development and will take advantage of new features if needed (and update meta/main.yml for minimum version)
Compatible OS. This role is tested through travis CI on CentOS 7, Ubuntu Xenial (16.04) and Bionic (18.04), Debian Jessie and stretch for time being.
Java 8 (mandatory)
- Oracle Java 8 is the official supported platform by Sonatype
- openjdk8 is know to work and is used for deployment test on travis on the corresponding platform docker images.
- For more information see nexus3 system requirements
Apache HTTPD (optional)
- Used to setup a SSL reverse-proxy
- The following modules must be enabled in your configuration: mod_ssl, mod_rewrite, mod_proxy, mod_proxy_http, mod_headers.

(see Dependencies section below for matching roles on galaxy)

Role Variables

Ansible variables, along with the default values (see default/main.yml) :

General variables

    nexus_version: ''
    nexus_timezone: 'UTC'
    nexus_download_url: "http://download.sonatype.com/nexus/3"

The role will install latest nexus available version by default. You may fix the version by setting the nexus_version variable. See available versions at https://www.sonatype.com/download-oss-sonatype.

If you fix the version and change it to a different one, the role will try to upgrade your installation. Make sure to change to a later version in release history. Downgrading will fail (unless you re-install from scratch using the nexus_purge special var)

If you don't fix the version and play the role on an existing installation, the current installed version will be used (detecting target of {{ nexus_installation_dir }}/nexus-latest). If you want to upgrade nexus, you will have to pass the special var nexus_upgrade=true on the ansible-playbook command line. See Upgrade nexus to latest version

If you use an older version of nexus than the lastest, you should make sure you do not use features which are not available in the installed release (e.g. yum hosted repositories for nexus < 3.8.0, git lfs repo for nexus < 3.3.0, etc.)

nexus_timezone is a Java Timezone name and can be useful in combination with nexus_scheduled_tasks cron expressions below.

You may change the download site for packages by tuning nexus_download_url (e.g. closed environment, proxy/cache on your network...). In this case, the automatic detection of the latest version will most likelly fail and you will have to fix the version to download. If you still want to take advantage of automatic latest version detection, a call to <your_custom_location>/latest-unix.tar.gz must return an HTTP 302 redirect to the latest available version in your cache/proxy.

Download dir for nexus package

    nexus_download_dir: '/tmp'

Directory on target where the nexus package will be downloaded.

Nexus port and context path

    nexus_default_port: 8081
    nexus_default_context_path: '/'

Port and context path of the java nexus process. nexus_default_context_path has to keep the trailing slash when set, for ex. : nexus_default_context_path: '/nexus/'.

Nexus OS user and group

    nexus_os_group: 'nexus'
    nexus_os_user: 'nexus'

User and group used to own the nexus files and run the service, those will be created by the role if absent.

    nexus_os_user_home_dir: '/home/nexus'

Allow to change the nexus user default home directory

Nexus instance directories

    nexus_installation_dir: '/opt'
    nexus_data_dir: '/var/nexus'
    nexus_tmp_dir: '/tmp/nexus'

Nexus directories, nexus_installation_dir contains the installed executable(s), nexus_data_dir contains all configuration, repositories and uploaded artifacts. Note: custom blobstores paths outside of nexus_data_dir can be configured, see nexus_blobstores below.

Nexus JVM Ram setting

    nexus_min_heap_size: "1200M"
    nexus_max_heap_size: "{{ nexus_min_heap_size }}"
    nexus_max_direct_memory: "2G"

These are the defaults for Nexus. Please do not modify those values unless you have read the memory section of nexus system requirements and you understand what you are doing.

As a second warning, here is an extract from the above document:

Increasing the JVM heap memory larger than recommended values in an attempt to improve performance is not recommended. This actually can have the opposite effect, causing the operating system to thrash needlessly.

Admin password

    nexus_admin_password: 'changeme'

The 'admin' account password to setup. This works only on first time install by default. Please see Change admin password after first install if you want to change it later with the role.

It is strongly advised that you do not keep your password in clear text in you playbook and use ansible-vault encryption (either inline or in a separate file loaded with include_vars for example)

Default anonymous access

    nexus_anonymous_access: false

Allow anonymous access to nexus.

Public hostname

    public_hostname: 'nexus.vm'

The fully qualified domain name under which the nexus instance will be accessible to its clients.

Branding capabalities

    nexus_branding_header: ""
    nexus_branding_footer: "Last provisionned {{ ansible_date_time.iso8601 }}"

Header and footer branding, those can contain HTML.

Audit capability

    nexus_audit_enabled: false

The Auditing capability of nexus is off by default. You can turn it on by switching this to true. Please note that the audit data is stored in nexus db, persits accross reboots and is not automatically rotated/cleared.

Reverse proxy setup

    httpd_setup_enable: false
    httpd_ssl_certificate_file: 'files/nexus.vm.crt'
    httpd_ssl_certificate_key_file: 'files/nexus.vm.key'

Setup an SSL Reverse-proxy, this needs httpd installed. Note : when httpd_setup_enable is set to true, nexus binds to 127.0.0.1:8081 thus not being directly accessible on HTTP port 8081 from an external IP.

    httpd_copy_ssl_files: true  # Default is false
    # These specifies to the vhost where to find on the remote server file
    # system the certificate files.
    httpd_ssl_cert_file_location: "/etc/pki/tls/certs/wildcard.vm.crt"
    httpd_ssl_cert_key_location: "/etc/pki/tls/private/wildcard.vm.key"

Use already existing SSL certificates on the server file system for the https reverse proxy

    httpd_default_admin_email: "admin@example.com"

Set httpd default admin email address

Blobstores and repositories

    nexus_delete_default_repos: false

Delete the repositories from the nexus install initial default configuration. This step is only executed on first-time install (when nexus_data_dir has been detected empty).

    nexus_delete_default_blobstore: false

Delete the default blobstore from the nexus install initial default configuration. This can be done only if nexus_delete_default_repos: true and all configured repositories (see below) have an explicit blob_store: custom. This step is only executed on first-time install (when nexus_data_dir has been detected empty).

    nexus_blobstores: []
    # example blobstore item :
    # - name: separate-storage
    #   type: file
    #   path: /mnt/custom/path
    # - name: s3-blobstore
    #   type: S3
    #   config:
    #     bucket: s3-blobstore
    #     accessKeyId: "{{ VAULT_ENCRYPTED_KEY_ID }}"
    #     secretAccessKey: "{{ VAULT_ENCRYPTED_ACCESS_KEY }}"

Blobstores to create. A blobstore path and a repository blobstore cannot be updated after initial creation (any update here will be ignored on re-provisionning).

Configuring blobstore on S3 is provided as a convenience and is not part of the automated tests we run on travis. Please note that storing on S3 is only recommended for instances deployed on AWS.

      - name: private-release
        version_policy: release
        write_policy: allow_once  # one of "allow", "allow_once" or "deny"

Maven hosted repositories configuration. Negative cache config is optionnal and will default to the above values if omitted.

    nexus_repos_maven_group:
      - name: public
        member_repos:
          - central
          - jboss

Maven group repositories configuration.

All three repository types are combined with the following default values :

    _nexus_repos_maven_defaults:
      blob_store: default # Note : cannot be updated once the repo has been created
      strict_content_validation: true
      version_policy: release # release, snapshot or mixed

      negative_cache_enabled: true # Nexus gui default. For proxies only
      negative_cache_ttl: 1440 # Nexus gui default. For proxies only

Docker, Pypi, Raw, Rubygems, Bower, NPM, Git-LFS and yum repository types: see defaults/main.yml for these options:

      nexus_config_pypi: false
      nexus_config_docker: false
      nexus_config_raw: false
      nexus_config_rubygems: false
      nexus_config_bower: false
      nexus_config_npm: false
      nexus_config_gitlfs: false
      nexus_config_yum: false

These are all false unless you override them from playbook / group_var / cli, these all utilize the same mechanism as maven.

Note that you might need to enable certain security realms if you want to use other repository types than maven. These are false by default

nexus_nuget_api_key_realm: false
nexus_npm_bearer_token_realm: false
nexus_docker_bearer_token_realm: false  # required for docker anonymous access

The Remote User Realm can also be enabled with

nexus_rut_auth_realm: true

and the header can be configured by defining

nexus_rut_auth_header: "CUSTOM_HEADER"

Scheduled tasks

    nexus_scheduled_tasks: []
    #  #  Example task to compact blobstore :
    #  - name: compact-docker-blobstore
    #    cron: '0 0 22 * * ?'
    #    typeId: blobstore.compact
    #    task_alert_email: alerts@example.org  # optional
    #    taskProperties:
    #      blobstoreName: {{ nexus_blob_names.docker.blob }} # all task attributes are stored as strings by nexus internally
    #  #  Example task to purge maven snapshots
    #  - name: Purge-maven-snapshots
    #    cron: '0 50 23 * * ?'
    #    typeId: repository.maven.remove-snapshots
    #    task_alert_email: alerts@example.org  # optional
    #    taskProperties:
    #      repositoryName: "*"  # * for all repos. Change to a repository name if you only want a specific one
    #      minimumRetained: "2"
    #      snapshotRetentionDays: "2"
    #      gracePeriodInDays: "2"
    #    booleanTaskProperties:
    #      removeIfReleased: true
    #  #  Example task to purge unused docker manifest and images
    #  - name: Purge unused docker manifests and images
    #    cron: '0 55 23 * * ?'
    #    typeId: "repository.docker.gc"
    #    task_alert_email: alerts@example.org  # optional
    #    taskProperties:
    #      repositoryName: "*"  # * for all repos. Change to a repository name if you only want a specific one
    #  #  Example task to purge incomplete docker uploads
    #  - name: Purge incomplete docker uploads
    #    cron: '0 0 0 * * ?'
    #    typeId: "repository.docker.upload-purge"
    #    task_alert_email: alerts@example.org  # optional
    #    taskProperties:
    #      age: "24"

Scheduled tasks to setup. typeId and task-specific taskProperties/booleanTaskProperties can be guessed either:

from the java type hierarchy of org.sonatype.nexus.scheduling.TaskDescriptorSupport
by inspecting the task creation html form in your browser
from peeking at the browser AJAX requests while manually configuring a task.

Task properties must be declared in the correct yaml block depending on their type:

taskProperties for all string properties (i.e. repository names, blobstore names, time periods...).
booleanTaskProperties for all boolean properties (i.e. mainly checkboxes in nexus create task GUI).

Backups

      nexus_backup_configure: false
      nexus_backup_cron: '0 0 21 * * ?'  # See cron expressions definition in nexus create task gui
      nexus_backup_dir: '/var/nexus-backup'
      nexus_restore_log: '{{ nexus_backup_dir }}/nexus-restore.log'
      nexus_backup_rotate: false
      nexus_backup_rotate_first: false
      nexus_backup_keep_rotations: 4  # Keep 4 backup rotation by default (current + last 3)

Backup will not be configured unless you switch nexus_backup_configure: true. In this case, a scheduled script task will be configured in nexus to run at interval specified by nexus_backup_cron (defaults to 21:00 every day). See the groovy template for this task for details. This scheduled task is independent from the other nexus_scheduled_tasks you declare in your playbook

If you want to rotate backups, set nexus_backup_rotate: true and adjust the number of rotations you would like to keep with nexus_backup_keep_rotations (defaults to 4).

When using rotation, if you want to save extra disk space during the backup process, you can set nexus_backup_rotate_first: true. This will configure a pre-rotation rather than the default post-rotation. Please note than in this case, old backup(s) is/are removed before the current one is done and successful.

Restore procedure

Run your playbook with parameter -e nexus_restore_point=<YYYY-MM-dd-HH-mm-ss> (e.g. 2017-12-17-21-00-00 for 17th of December 2017 at 21h00m00s)

Possible limitations

Blobstore copies are made directly from nexus by the script scheduled task. This has only been tested on rather small blobstores (less than 50Go) and should be used with caution and tested carefully on larger installations before moving to production. In any case, you are free to implement your own backup scenario outside of this role.

Special maintenance/debug variables

These are not present in defaults/main.yml and are meant to be used on the command line only for maintenance/debug reasons.

Purge nexus

** Warning: this will completely erase the current data. Make sure to backup previously if needed **

Use the nexus_purge variable if you need to restart from scratch and re-install a blank instance of nexus.

ansible-playbook -i your/inventory.ini your_nexus_playbook.yml -e nexus_purge=true

Force groovy scripts registration

This one is safe and will only make the playbook run longer if it wasn't needed

For performance sake, we use a little trick with several rsync to detect which maintenance groovy scripts need to be registered in Nexus. On some occasions (e.g. bad admin password, recovering a backup from a previous nexus instance with unregistered scripts...), this can lead to situation where the role will fail when attempting to run the needed groovy scripts.

The symptom: you get HTTP 404 errors when the role tries to run scripts like in the following example (use -v option for ansible playbook):

fatal: [nexus3-oss]: FAILED! => {"changed": false, "connection": "close", "content": "", "date": "Tue, 11 Sep 2018 07:57:44 GMT", "msg": "Status code was 404 and not [200, 204]: HTTP Error 404: Not Found", "redirected": false, "server": "Nexus/3.13.0-01 (OSS)", "status": 404, "url": "http://localhost:8081/service/rest/v1/script/update_admin_password/run", "x_content_type_options": "nosniff", "x_siesta_faultid": "914acef2-f644-4bd6-9a7d-ce19255ea3dd"}

In such cases, you can force the (re-)registration of the groovy scripts with the nexus_force_groovy_scripts_registration variable:

ansible-playbook -i your/inventory.ini your_playbook.yml -e nexus_force_groovy_scripts_registration=true

Change admin password after first install

    nexus_default_admin_password: 'admin123'

This should not be changed in your playbook. This var is filled with the default nexus admin password on first install and ensures we can change the admin password to nexus_admin_password.

If you want to change your admin password after first install, you can temporarily change this to your old password from the command line. After changing nexus_admin_password in your playbook, you can run:

ansible-playbook -i your/inventory.ini your_playbook.yml -e nexus_default_admin_password=oldPassword

Upgrade nexus to latest version

    nexus_upgrade: true

This variable has no effect if nexus_version is fixed in your vars

Unless you set this variable, the role will keep the current installed nexus version when running against an already provisionned host. Passing this extra var will trigger automatic latest nexus version detection and upgrade if a newer version is available.

Setting this var as part of your playbook breaks idempotence (i.e. your playbook will make changes to your system if a new version is available although no parameters have changed)

We strongly suggest to use this variable only as an extra var to ansible-playbook call

ansible-playbook -i your/inventory.ini your_playbook.yml -e nexus_upgrade=true

Dependencies

The java and httpd requirements /can/ be fulfilled with the following galaxy roles :

Feel free to use them or implement your own install scenario at your convenience.

Development, Contribution and Testing

Contributions

All contributions to this role are welcome, either for bugfixes, new features or documentation.

If you wish to contribute:

Fork the repo under your own name/organisation through github interface
Create a branch in your own repo with a meaningfull name. We suggest the following naming convention:
- feat/<someFeature> for features
- fix/<someBugFix> for bug fixes
- docfix/<someDocFix> for documentation only fixes
If starting an important feature change, open a pull request early describing what you want to do so we can discuss it if needed. This will prevent you from doing a lot of hard work on a lot of code for changes that we cannot finally merge.
If there are build error on your pull request, have a look at the travis log and fix the relevant errors.

Moreover, if you have time to devote for code review, merge for realeases, etc... drop an email to contact@thoteam.com to get in touch.

Testing

This role includes tests and CI integration through travis. At time being, we test:

groovy scripts syntax
yaml syntax and coding standard (yamllint)
ansible good practices (ansible lint)
a set of basic deployments on 5 different linux platforms
- centos7
- debian jessie
- debian stretch
- ubuntu xenial (16.04)
- ubuntu bionic (18.04)

Groovy syntax

This role contains a set of groovy files used to provision nexus.

If you submit changes to groovy files, please run the groovy syntax check locally before pushing your changes

./tests/test_groovySyntax.sh

This will ensure you push groovy files with correct syntax limiting the number of check errors on travis.

You will need the groovy package installed locally to run this test.

Molecule default-xxxx scenarii

The role is tested on travis with molecule. You can run these tests locally. The best way to achieve this is through a python virtualenv. You can find some more details in requirements.txt.

# Note: the following path should be outside the working dir
virtualenv /path/to/some/pyenv
. /path/to/some/pyenv/bin/activate
pip install -r requirements.txt
molecule [create|converge|destroy|test] -s <scenario name>
deactivate

Please have a look at molecule documentation (a good start is molecule --help) for further usage.

The current proposed scenarii refer to the tested platforms (see molecule/ directory). If you launch a scenario ans leave the container running (i.e. using converge for a simple deploy), you can access the running instance from your browser at https://localhost:. See the molecule/<scenario>/molecule.yml file for detail. As a convenience, here is the correspondence between scenarii and configured ports:

default-centos7 => https://localhost:8090
default-debian_jessie => https://localhost:8091
default-debian_stretch => https://localhost:8092
default-ubuntu_16.04 => https://localhost:8093
default-ubuntu_18.04 => https://localhost:8094

To speed up tests, molecule uses automated docker build images on docker hub:

Molecule selinux scenario

We included a second molecule selinux scenario. This one is not run on travis but can be used locally to:

test selinux integration (on centos).
run test and access the running vms under VirtualBox on you local machine.

If you wish to use this scenario you will need

VirtualBox
Vagrant
molecule

A typical workflow runs like this:

molecule create -s selinux. Once this is complete, you will see two vagrant vms (centos7 and debian-stretch) in your VirtualBox console. These Vagrant box are taken from http://vagrant.thoteam.com
molecule converge -s selinux will run the scenario test playbook against the two vms. You can pass additionnal variables to ansible on the command line to override playbook or default vars (e.g. molecule converge -s selinux -- -e nexus_backup_rotate=true). You can converge as many times as you want.
You can now access the gui with https://localhost:9101 (centos7) or https://localhost:9102 (debian-stretch). You will need to add a security exception for the self signed ssl certificate. If you did not change it with a command line var above, the default role admin password is "changeme"
When you're happy with your testing, you can recycle the used space with molecule destroy -s selinux
