files and their purpose

1. config/main.yml

Contains configuration values that determine which Docker image version to use and what hostname the container will be registered under.

• version (string):

  • Default: "latest"
  • The MariaDB image tag to pull (e.g. 10.6, 10.11, or latest).

• hostname (string):

  • Default: "central-mariadb"
  • The container name and DNS alias within the central_mariadb network. Used by other services (like Moodle) to connect.

Tip: Pin to a specific minor version (e.g., 10.6.12) in production to avoid breaking changes on rebuilds.

2. main.yml

Minimal file defining the application identifier for the role.

• application_id (string):

  • Default: "mariadb"
  • Logical name used in templates, notifications, or paths when multiple roles/services may coexist.
