vars/

This directory contains variable definition files for the docker-mariadb Ansible role. It centralizes all configurable values related to MariaDB deployment and can be adjusted without modifying task logic.

files and their purpose

1. configuration.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

  • application_id (string):

    • Default: "mariadb"

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