Continuous Delivery with Docker and Jenkins

Ansible Galaxy

Ansible Galaxy is to Ansible what Docker Hub is for Docker-it stores common roles, so that they can be reused by others. You can browse the available roles on the Ansible Galaxy page at: https://galaxy.ansible.com/.

To install the role from Ansible Galaxy, we can use the ansible-galaxy command.

$ ansible-galaxy install username.role_name

This command automatically downloads the role. In the case of the MySQL example, we could download the role by executing:

$ ansible-galaxy install geerlingguy.mysql

The command downloads the mysql role, which can be later used in the playbook file.

If you need to install a lot of roles at the same time, you can define them in the requirements.yml file and use ansible-galaxy install -r requirements.yml ...
