computer-playbook/roles/sys-stk-back-stateful/README.md
Kevin Veen-Birkenbach 6ea8301364 Refactor: migrate cmp/* and srv/* roles into sys-stk/* and sys-svc/* namespaces 
- Removed obsolete 'cmp' category, introduced 'stk' category (fa-bars-staggered icon).
- Renamed roles:
  * cmp-db-docker → sys-stk-back-stateful
  * cmp-docker-oauth2 → sys-stk-back-stateless
  * srv-domain-provision → sys-stk-front
  * cmp-db-docker-proxy → sys-stk-full-stateful
  * cmp-docker-proxy → sys-stk-full-stateless
  * cmp-rdbms → sys-svc-rdbms
- Updated all include_role references, vars, templates and README.md files.
- Adjusted run_once comments and variable paths accordingly.
- Updated all web-app roles to use new sys-stk/* and sys-svc/* roles.

Database Docker Composition

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

Features

  • Central RDBMS Integration
    Includes the sys-svc-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/sys-svc-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 sys-svc-rdbms role to provision the database, backups, and users.
