-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: username.rolename, x: 42 }
+         - { role: docker_auth }
       vars:
          - { sso_url: "auth.example.org" }
          - { ldap_url: "ldap.example.org" }
