Rework deployment of services with backup in my personal infra

[Its-Alex]

Context

Backups are set up by leveraging sidecar containers, activated through Jinja:

  ...
  postgres:
    image: postgres:17-alpine
    restart: unless-stopped
    volumes:
      - ./postgres/data/:/var/lib/postgresql/data/
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "miniflux"]
      interval: 10s
      start_period: 30s
{% if miniflux_enable_s3_backup_postgres | bool %}
  pg_back:
    ...
{% endif %}
  ...

However, restoration via sidecars isn't possible with this configuration. I'd like to modify it to support restoration—even when backups are ongoing.

Todo

• Investigate:
  • service profile
  • ansible docker compose service
• Implement the preferred solution in the repository
