Figure 3. I love the command line, but these search results are frustrating.

Once you install a role, it is immediately available for you to use in your own playbooks, because it’s installed in the system-wide roles folder. In my case, that’s /etc/ansible/roles (Figure 4). So now, if I create a playbook like this:

---

- hosts: cadlab

roles:

- geerlingguy.apache

Apache will be installed on all my cadlab computers, regardless of what distribution they’re using. If you want to see how the role (which is just a bunch of tasks, handlers and so forth) works, just pick through the folder structure inside /etc/ansible/roles/geerlingguy.apache/. It’s all right there for you to use or modify.
