4.6 Service Dependencies and Startup Order

Critical Path Dependencies:

• PostgreSQL→ Authentik, Paperless, Vikunja, Nextcloud
• MariaDB→ BookStack
• Traefik→ All web services (SSL termination)
• Authentik→ Services requiring authentication

Startup Recommendations:

• Deploy infrastructure stack (Traefik, databases)
• Deploy authentication stack (Authentik)
• Deploy application stacks
• Deploy monitoring and management tools

Health Check Patterns: Most services include automatic health checks and restart policies:

deploy:
  restart_policy:
    condition: any
    delay: 5s
    max_attempts: 3
