Installing and configuring Nexus Sonatype using the infrastructure as code approach

Sonatype Nexus is an integrated platform that allows developers to proxy, store, and manage Java (Maven) dependencies, Docker, Python, Ruby, NPM, Bower, RPM packages, gitlfs, Apt, Go, Nuget, and distribute their software security.

Why do you need Sonatype Nexus?

• To store private artifacts;
• For caching artifacts that are downloaded from the Internet;

Artifacts supported in the base distribution of Sonatype Nexus:

• Java, Maven (jar)
• Docker
• Python (pip)
• ruby (gem)
• NPM
• bower
• Yum (rpm)
• gitlfs
• Raw
• Apt (deb)
• Go
• nuget

Role Variables

Role Variables

Variables with default values ​​(see default/main.yml):

General variables

    nexus_version: ''
    nexus_timezone: 'UTC'

By default, the role will install the latest version of Nexus available. You can fix the version by changing the variable nexus_version. See available versions at https://www.sonatype.com/download-oss-sonatype.

If you change to a newer version, the role will attempt to update your installed Nexus.

If you are using an older version of Nexus than the latest, you must ensure that you are not using features that are not available in the installed release (e.g. hosting yum repositories available for nexus greater than 3.8.0, git lfs repo for nexus greater than 3.3.0 etc.)

nexus timezone is the Java time zone name, which can be useful in combination with the following cron expressions for nexus_scheduled tasks.

Nexus port and context path

    nexus_default_port: 8081
    nexus_default_context_path: '/'

The port and context path of the Java connection process. nexus_default_context_path must contain a slash when set, e.g.: nexus_default_context_path: '/nexus/'.

Nexus OS user and group

    nexus_os_group: 'nexus'
    nexus_os_user: 'nexus'

The user and group used to own the Nexus files and run the service will be created by the role, if not present.

    nexus_os_user_home_dir: '/home/nexus'

Allow changing default home directory for nexus user

Nexus instance directories

    nexus_installation_dir: '/opt'
    nexus_data_dir: '/var/nexus'
    nexus_tmp_dir: "{{ (ansible_os_family == 'RedHat') | ternary('/var/nexus-tmp', '/tmp/nexus') }}"

Nexus directories.

• nexus_installation_dir contains installed executables
• nexus_data_dir contains all configuration, repositories and downloaded artifacts. Custom blobstore paths nexus_data_dir can be customized, see below nexus_blobstores.
• nexus_tmp_dir contains all temporary files. The default path for redhat has been moved from /tmp to overcome potential problems with automatic cleaning procedures. See #168.

Setting Nexus JVM Memory Usage

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

These are the default settings for the Nexus. Please do not change these values. If you haven't read nexus system requirements memory section and don't know what they're doing.

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

It is not recommended to increase the JVM heap beyond the recommended values ​​in an attempt to improve performance. It can actually have the opposite effect, causing the operating system to run unnecessarily.

Administrator password

    nexus_admin_password: 'changeme'

Account password "admin" for configuration. This only works on first install by default. Please see [Change admin password after first install](# change-admin-password-after-first-install) if you want to change it later with a role.

It is highly recommended not to store your password in cleartext in the playbook, but to use [ansible-vault encryption] (https://docs.ansible.com/ansible/latest/user_guide/vault.html) (either built-in or in a separate file loaded, for example, using include_vars)

Anonymous access by default

    nexus_anonymous_access: false

Anonymous access is disabled by default. More about anonymous access.

Public hostname

    nexus_public_hostname: 'nexus.vm'
    nexus_public_scheme: https

The fully qualified domain name and scheme (https or http) by which the Nexus instance will be accessible to its clients.

API access for this role

    nexus_api_hostname: localhost
    nexus_api_scheme: http
    nexus_api_validate_certs: "{{ nexus_api_scheme == 'https' }}"
    nexus_api_context_path: "{{ nexus_default_context_path }}"
    nexus_api_port: "{{ nexus_default_port }}"

These variables control how the role connects to the Nexus API for provisioning.
For advanced users only. Chances are you don't want to change these default settings.

Reverse proxy setup

    httpd_setup_enable: false
    httpd_server_name: "{{ nexus_public_hostname }}"
    httpd_default_admin_email: "[email protected]"
    httpd_ssl_certificate_file: 'files/nexus.vm.crt'
    httpd_ssl_certificate_key_file: 'files/nexus.vm.key'
    # httpd_ssl_certificate_chain_file: "{{ httpd_ssl_certificate_file }}"
    httpd_copy_ssl_files: true

Set SSL Reverse Proxy.
To do this, you need to install httpd. Note: when for httpd_setup_enable set valuetrue, nexus binds to 127.0.0.1:8081, so not being directly accessible on HTTP port 8081 from an external IP address.

The default hostname to use is nexus_public_hostname. If you need different names for whatever reason, you can set httpd_server_name with a different meaning.

С httpd_copy_ssl_files: true (default) The above certificates must exist in your playbook directory and will be copied to the server and configured in apache.

If you want to use existing certificates on the server, install httpd_copy_ssl_files: false and provide the following variables:

    # 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"
    # httpd_ssl_cert_chain_file_location: "{{ httpd_ssl_cert_file_location }}"

httpd_ssl_cert_chain_file_location is optional and should be left unset if you don't want to customize the chain file

    httpd_default_admin_email: "[email protected]"

Set default admin email address

LDAP Configuration

LDAP connections and security scope disabled by default

    nexus_ldap_realm: false
    ldap_connections: []

Removing repositories from the original Nexus default configuration. This step is only performed during the first installation (when nexus_data_dir empty).

    nexus_delete_default_blobstore: false

Delete the default blobstore from the nexus install initial default configuration. This can only be done 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).

Deleting blob storage (binary artifacts) is disabled by default from the initial configuration. To remove blob storage (binary artifacts), turn off nexus_delete_default_repos: true. This step is only performed during the first installation (when nexus_data_dir empty).

Scheduled Tasks for settings. typeId and task-specifictaskProperties/booleanTaskProperties you can either guess:

• from the Java type hierarchy org.sonatype.nexus.scheduling.TaskDescriptorSupport
• validating the task creation HTML form in your browser
• from viewing AJAX requests in the browser while manually configuring the task.

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

• taskProperties for all string properties (i.e. repository names, repository names, time periods...).
• booleanTaskProperties for all boolean properties (i.e. basically checkboxes in the GUI of the nexus creation task).

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)

The backup will not be configured until you switch nexus_backup_configure в true.
In this case, the script scheduled task will be configured to run on the Nexus
at the interval specified in nexus_backup_cron (default 21:00 every day).
See the [groovy template for this task](templates / backup.groovy.j2) for details.
This scheduled task is independent of others nexus_scheduled_taskswhich you
announce in your playbook.

If you want to rotate/delete backups, install nexus_backup_rotate: true and set the number of backups you would like to keep with nexus_backup_keep_rotations (default 4).

When using rotation, if you want to save extra disk space during the backup process,
You can install nexus_backup_rotate_first: true. This will set up pre-rotation/removal before backup. By default, rotation occurs after the backup is created. Note than in this case old backups
will be deleted before the current backup is made.

Recovery procedure

Run playbook with parameter -e nexus_restore_point=<YYYY-MM-dd-HH-mm-ss>
(for example, 2017-12-17-21-00-00 for December 17, 2017 at 21:00

Removing nexus

Warning: this will completely delete the current data. Be sure to back up earlier if needed

Use a variable nexus_purgeif you need to restart from scratch and reinstall the nexus instance with all data removed.

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

Change administrator password after first installation

    nexus_default_admin_password: 'admin123'

This should not be changed in your playbook. This variable is populated with the default Nexus admin password on first install and ensures that we can change the admin password to nexus_admin_password.

If you want to change the administrator password after the first installation, you can temporarily change it to the old password from the command line. After the change nexus_admin_password in your playbook you can run:

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