# Core Infrastructure Services
# These services form the foundation of the homelab and should always be running
# Place in /opt/stacks/core/docker-compose.yml

# RESTART POLICY GUIDE:
# - unless-stopped: Core infrastructure services that should always run
# - no: Services with Sablier lazy loading (start on-demand)
# - See individual service comments for specific reasoning

  # Sablier - Lazy loading service for Docker containers
  # Controls startup/shutdown of lazy-loaded services, must always run
  # REQUIREMENTS FOR DOCKER API ACCESS:
  # 1. Docker daemon must be configured to listen on TCP port 2376 with TLS
  # 2. DOCKER_HOST environment variable must point to accessible Docker API endpoint
  # 3. Firewall must allow TCP connections to Docker API port (2376)
  # 4. TLS certificates must be mounted and environment variables set
  # 5. Ensure dockerproxy service is running and accessible
