Database Docker Composition

This role combines the central RDBMS role (cmp-rdbms) with Docker Compose to deliver a ready-to-use containerized database environment.

Features

• Central RDBMS Integration
  Includes the cmp-rdbms role, which handles backups, restores, user and permission management for your relational database system (PostgreSQL, MariaDB, etc.).

• Docker Compose
  Utilizes the standalone docker-compose role to define and bring up containers, networks, and volumes automatically.

• Variable Load Order

  1. Docker Compose variables (roles/docker-compose/vars/docker-compose.yml)
  2. Database variables (roles/cmp-rdbms/vars/database.yml)
     Ensures compose ports and volumes are defined before the database role consumes them.

The role will load both sub-roles and satisfy all dependencies transparently.

Task Breakdown

1. Set Fact database_application_id to work around lazy‐loading ordering.
2. Include Vars in the specified order.
3. Invoke docker-compose role to create containers, networks, and volumes.
4. Invoke cmp-rdbms role to provision the database, backups, and users.
