# NestJS API + Next.js web on galactus (standalone Docker, Portainer endpoint 3).
#
# Standalone port of deploy/jorgecuadros-app.stack.yml — see the header of
# deploy/galactus/jorgecuadros-db.compose.yml for the Swarm keys plain compose
# silently ignores. The one that matters most here: without
# `restart: unless-stopped` neither service returns after a host reboot.
#
# Cross-stack traffic still goes over the HOST, not service DNS. db and minio
# are separate Portainer stacks, so they are on separate compose networks and
# their service names do not resolve from here. DATABASE_URL / S3_ENDPOINT must
# name galactus's own address and the published port — exactly as on cubex
# today. Do not "simplify" them to `mysql:3306`.
#
# ...which means these containers have to resolve galactus's MagicDNS name, and
# by default they CANNOT. The host runs systemd-resolved, whose 127.0.0.53 stub
# is unreachable from a container, so Docker falls back to the upstream resolver
# in /run/systemd/resolve/resolv.conf — the LAN router, which knows nothing
# about the tailnet. Routing to 100.x works fine; only the lookup fails, and the
# API dies with Prisma P1001 "can't reach database server". Pointing the
# containers at Tailscale's own resolver fixes it. 100.100.100.100 is Tailscale's
# fixed anycast MagicDNS address (identical on every tailnet); the search domain
# is this tailnet's suffix.
#
# The web image is NOT URL-baked: the browser's API origin is injected at
# runtime from API_ORIGIN (apps/web/src/app/layout.tsx), so the same image works
# for any deployment. APP_VERSION / GIT_SHA / BUILD_DATE come baked in from
# build.yml and are surfaced at GET /version (api) and in the web footer.
#
# Keep in sync with deploy/jorgecuadros-app.stack.yml when either changes.
