Every service now has an explicit container_name, eliminating the
htpc-download-box_ prefix/suffix that compose derived from the directory.
Disambiguated duplicates follow type_context naming:
postgres_resume / postgres_famapp / postgres_authentik
minio_resume / minio_famapp
redis_authentik
Also updates CLAUDE.md and the homelab-ssh skill to reflect:
- compose v2 (docker compose, space) replacing the old v1.27.4 standalone
- dc alias updated to docker compose
- htpc-download-box directory is now clean (legacy cruft removed)
Server-side migration steps (docker-compose-plugin apt install, alias
update, Docker Engine upgrade, old binary removal) are documented in
the session but not yet applied — run apply-compose.ps1 -Compose after
completing them.
