# Infrastructure Services
# Core services that other services depend on
# Place in /opt/stacks/infrastructure/docker-compose.yml
# NOTE: Traefik, Authelia, DuckDNS, and Gluetun have their own separate stacks
# See /opt/stacks/traefik/, /opt/stacks/authelia/, etc.

# 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
