# Pad — production Docker Compose override
# Usage: docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
#
# Extends the base docker-compose.yml with:
# - Resource limits
# - Secure cookie settings
# - CORS configuration
# - Email (Maileroo) support
# - Named network for reverse proxy integration

services:
  pad:
    environment:
      PAD_SECURE_COOKIES: "true"
      # Override Redis URL to include password when REDIS_PASSWORD is set.
      # Without this, the pad container inherits the passwordless URL from
      # docker-compose.yml and fails to connect when Redis AUTH is enabled.

  redis:
    # noeviction, NOT allkeys-lru (BUG-2698). Pad's Redis holds the
    # session-presence registry as well as pub/sub, and evicting a live
    # session's entry is indistinguishable from its TTL lapsing: the
    # session disappears from the "push to agent" picker and a push
    # targeted at it reports delivered_sessions: 0 while it is still
    # connected. It self-repairs on the next 30s renewal, but the
    # keyspace is small — a few hundred bytes per connected session plus
    # two counters — so there is nothing to gain by evicting it. See
    # docs/deployment.md's Redis configuration notes.
