Kevin Veen-Birkenbach 379b1d420e Refactor MariaDB and PostgreSQL roles for Ansible 2.20 compatibility and Infinito.Nexus conventions

- Replace legacy docker_container-based MariaDB deployment with docker-compose based workflow
- Add custom Dockerfile and docker-compose templates for MariaDB
- Split MariaDB command into separate arguments to avoid entrypoint parsing errors
- Introduce MARIADB_CUSTOM_IMAGE and MARIADB_EXPOSE_LOCAL variables
- Add docker_compose_flush_handlers to ensure correct handler execution on first run
- Replace utils/once/finalize.yml with utils/once/flag.yml for new run-once semantics
- Align variable naming with Infinito.Nexus UPPERCASE conventions
- Fix PostgreSQL custom image variable name (POSTGRES_CUSTOM_IMAGE_NAME → POSTGRES_CUSTOM_IMAGE)
- Remove obsolete flush_handlers var injection in svc-db-postgres/tasks/main.yml
- General cleanup after migration from Ansible 2.18 → 2.20

feat(services): add CPU/RAM/PIDs defaults for heavy roles and align service names

defaults

Refactor DB initialization handling: externalize database_init flag for svc-db-mariadb and svc-db-postgres, remove internal auto-detection, and pass explicit init signal from sys-stk-back-stateful. Improves clarity, avoids incorrect credential lookups, and stabilizes central DB setup.

MariaDB

Overview

This Ansible role facilitates the deployment of a MariaDB server using Docker. It is designed to ensure ease of installation and configuration, with the flexibility to adapt to different environments.

Features

Dockerized MariaDB: Leverages Docker for MariaDB deployment, ensuring consistency across different environments.
Customizable Settings: Allows customization of the MariaDB instance through various Ansible variables.
Network Configuration: Includes setup of a dedicated Docker network for MariaDB.
Idempotent Design: Ensures that repeat runs of the playbook do not result in unwanted changes.
Security Focused: Implements best practices for securing the MariaDB root password.

Prerequisites

Before using this role, ensure you have the following:

Ansible installed on the control machine.
Docker installed on the target host(s).
Access to the target host(s) via SSH.

Configuration
