Dokploy injects 'networks' into all compose services for Traefik routing,
which is mutually exclusive with 'network_mode: service:supabase-kong'.
Changes:
- Remove network_mode from app service
- App server-side Supabase URL: http://supabase-kong:8000 (Docker DNS)
- App browser-side Supabase URL: ${API_EXTERNAL_URL} (external domain)
- Kong catch-all route: app:3000 instead of localhost:3000
Dokploy deployment fixes:
- Remove all host port bindings (Kong 8000/8443/3000, Studio 54323, Inbucket 54324,
DB 5432) — Traefik handles external routing in Dokploy, host ports conflict
with other services on the shared server
- Add idempotent ALTER ROLE password commands to db-migrate service — ensures
role passwords are set even when DB volume persists across deployments
(docker-entrypoint-initdb.d only runs on empty data dirs)
- Add catch-all app route to Kong config — proxies / to localhost:3000
(Next.js app via network_mode: service:supabase-kong)
