# Infrastructure Services
# SABLIER SESSION DURATION: Set to 5m for testing. Increase to 30m for production in config-templates/traefik/dynamic/sablier.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

services:
  dockerproxy:
    # Docker socket proxy for security - provides safe Docker API access, must always run
    # REQUIREMENTS FOR SABLIER INTEGRATION:
    # 1. Docker daemon must be configured to listen on TCP port 2375 (not just unix socket)
    # 2. Firewall must allow access to port 2375 from Sablier service
    # 3. Docker daemon config should include: 'hosts': ['tcp://0.0.0.0:2375', 'unix:///var/run/docker.sock']
    # 4. For security, consider restricting access to specific IP ranges or using TLS
    # 5. dockerproxy runs for additional security but doesn't expose port 2375 (handled by Docker daemon)
