Docker on VM with Traefik + Homepage

Overview

Deploy Docker services on the VM (Pop!_OS). Web services go behind Traefik (port 80) and register on Homepage (dashboard at /).

• Access domain: vm.local (mDNS) — use for app CMD_DOMAIN/BASE_URL, NOT vm
• Network: traefik-proxy (external bridge) — all web containers must join
• Crane: ~/go/bin/crane (NOT on PATH)
• Compose: docker compose (plugin at ~/.docker/cli-plugins/). Must cd into service dir — -f flag broken
