One of the key features that contributes to Ansible’s popularity is its extensive ecosystem of community-contributed content, known as Ansible Galaxy. Ansible Galaxy is a hub for discovering and sharing Ansible roles, which are reusable automation components that encapsulate tasks, variables, and other Ansible functionality. These roles are created and shared by the Ansible community, allowing users to quickly find and incorporate pre-built automation into their own projects.
The Ansible Galaxy platform serves as a centralized repository where users can browse, download, and install these community-contributed roles. It provides a user-friendly interface for searching, filtering, and rating available roles, making it easy for beginners and experienced users alike to find the right automation solutions for their needs.
How can beginners use Ansible Galaxy?
As a beginner, Ansible Galaxy can be an invaluable resource for kickstarting your automation journey.
Here are some ways you can leverage Ansible Galaxy:
- Discover existing roles: Ansible Galaxy hosts thousands of roles covering a wide range of use cases, from setting up development environments to managing cloud infrastructure. Use the search functionality to find roles that address your specific needs, and review the role descriptions, documentation, and ratings to assess their suitability.
- Install and use roles: Once you’ve identified a role that fits your requirements, you can install it directly from Ansible Galaxy using the
ansible-galaxycommand-line tool. This allows you to quickly incorporate pre-built automation into your own Ansible playbooks, saving you time and effort. - Learn from role examples: Examining the structure and contents of community-contributed roles can be an excellent way for beginners to learn Ansible best practices. Studying the YAML syntax, task definitions, and variable usage in these roles can help you understand how to write your own effective Ansible playbooks.
- Contribute your own roles: As you gain more experience with Ansible, consider sharing your own automation solutions with the community by creating and publishing roles on Ansible Galaxy. This not only helps others but also reinforces your own learning and solidifies your Ansible expertise.
The ansible-galaxy command will be your cockpit for managing roles in the long run.
ansible-galaxy role init common
As always in Ansible commands, here you can use the --help option to read information.
To list the currently installed roles with setting the roles path to your project directory use the following command:
ansible-galaxy role list --roles-path ./
It is possible to search roles on Ansible Galaxy from the command line.
ansible-galaxy role search apache2
After finding a role you like you can read more info about it.

If it fits to your requirements you can install it.
ansible-galaxy role install rrandev.myapache2 --roles-path ./
When you don’t use a role anymore you can remove it.
ansible-galaxy role remove rrandev.myapache2 --roles-path ./
