vars/

This directory contains variable definition files for the svc-db-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. meta/services.yml

The role’s service config (file root IS the services map keyed by <entity_name>). For svc-db-mariadb this carries the entity-keyed image, version, and hostname:

  • 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.
