Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

    - hosts: servers
      roles:
         - role: indigo-dc.galaxycloud
           GALAXY_ADMIN_EMAIL: "admin@elixir-italy.org"
           GALAXY_ADMIN_USERNAME: "admin"
           GALAXY_VERSION: "release_17.05"
           galaxy_instance_key_pub: "your_public_key"
           galaxy_instance_description: "INDIGO-CNR test"

Install Galaxy setting postgresql passwords:

    - hosts: servers
      roles:
         - role: indigo-dc.galaxycloud
           GALAXY_ADMIN_EMAIL: "admin@elixir-italy.org"
           GALAXY_ADMIN_USERNAME: "admin"
           GALAXY_VERSION: "release_17.05"
           galaxy_instance_key_pub: "your_public_key"
           galaxy_instance_description: "INDIGO-CNR test"
           set_pgsql_random_password: false
           galaxy_db_passwd: 'galaxy'
           set_proftpd_random_password: false
           proftpd_db_passwd: 'galaxy'

Setup Galaxy Docker container. The role, using ansible, automatically recognize the virtual platform (virtual machine or Docker contanier).

    - hosts: servers
      roles:
         - role: indigo-dc.galaxycloud
           GALAXY_ADMIN_EMAIL: "admin@elixir-italy.org"
           GALAXY_ADMIN_USERNAME: "admin"
           GALAXY_VERSION: "release_17.05"
           galaxy_instance_key_pub: "your_public_key"
           galaxy_instance_description: "INDIGO-CNR test"
           supervisor_manage_postgres: "True"
