This role installs and configures Nexus Repository Manager OSS version 3.x on CentOS/RHEL.
All configuration can be updated by re-running the role, except for the blobstores-related settings, which are immutable in nexus.
- This has only been tested on CentOS 7 + Ubuntu 16.04 (Xenial)
- Oracle Java 8 (mandatory)
- Apache HTTPD (optional, used to setup a SSL reverse-proxy)
(see Dependencies section below for matching roles on galaxy)
Ansible variables, along with the default values (see default/main.yml) :
nexus_version: '3.1.0-04'
nexus_timezone: 'UTC'
nexus_package: "nexus-{{ nexus_version }}-unix.tar.gz"
The nexus version and package to install, see available versions at https://www.sonatype.com/download-oss-sonatype . nexus_timezone is a Java Timezone name and can be useful in combination with nexus_scheduled_tasks cron expressions below.
nexus_download_dir: '/tmp'
Directory on target where the nexus package will be downloaded.
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_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_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_admin_password: 'changeme'
The 'admin' account password to setup. Note : admin password change subsequent to first-time provisioning/install is not implemented by this role yet.
nexus_anonymous_access: false
Allow anonymous access to nexus.

The fully qualified domain name under which the nexus instance will be accessible to its clients.
nexus_branding_header: ""
nexus_branding_footer: "Last provisionned {{ ansible_date_time.iso8601 }}"
Header and footer branding, those can contain HTML.
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.

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: []
