Oier Bravo Urtasun 67d1f82e6a refactor!: unify into one compose, drop airgap/mirror/dnsmasq/avahi/blessingskin
Collapse the override-file matrix into a single docker-compose.yml holding the
whole stack: drasl, minecraft, mc-backup, caddy, nmsr, uptime-kuma. Bring-up is
now just `docker compose up -d --build`.

Removed features (dead-ends for this deployment):
- airgap / full asset mirror (mirror-airgap.sh, mirror-mods.sh, 20-mirror.caddy,
  caddy local-CA export, /ca.crt)
- dnsmasq + avahi/mDNS + dns-records.sh + mdns-host-setup.sh + ENABLE_MDNS;
  DNS is now handled outside this repo (HOST_LAN_IP dropped)
- Blessing Skin auth variant (compose + 00-core-blessingskin.caddy + BS_* env)
- host-nginx-static variant (docker-compose.nginx.yml, nginx/ulicraft.conf.tmpl)
- build-stack.sh and its run modes (online/airgap/core)

Production ingress is the only path now: host nginx terminates TLS (LE certs)
in front of caddy on a localhost-only port; caddy routes every vhost by Host
header. Launcher downloads move mirror/launcher -> launcher/.

Docs: README, deploy skill, and plan/ rewritten to match; obsolete plan docs
(dnsmasq, blessing-skin, assets-mirror, full-airgap-mirror, dns-and-run-modes)
deleted.

Deployment — redeploy to cochi

Production host for the Ulicraft stack.

Host cochi (SSH alias)
Path /home/ubuntu/mc/ulicraft-server-v1
Branch main
Compose single docker-compose.yml (no overrides)
Auth Drasl (password login)
Ingress host nginx (Let's Encrypt TLS) → caddy → services (see 15-letsencrypt.md)
Restart hard (compose downcompose up --build) — brief full downtime

Routine redeploy

ssh cochi
cd /home/ubuntu/mc/ulicraft-server-v1
git pull --ff-only
tooling/render-config.sh        # re-render drasl/nmsr/pack configs from .env
docker compose down --remove-orphans
docker compose up -d --build

Or as a one-shot from your workstation:

ssh cochi 'set -e
  cd /home/ubuntu/mc/ulicraft-server-v1
  git pull --ff-only
  tooling/render-config.sh
  docker compose down --remove-orphans
  docker compose up -d --build'

render-config.sh re-renders configs (and render-pack.sh for the packwiz pack) from .env before the stack comes back up.

What survives a hard restart

Named volumes persist — world and auth data are safe:

  • mc_data — world + installed NeoForge/mods
  • drasl_state — Drasl accounts/skins
  • kuma_data — Uptime Kuma config/history
  • backups/ — mc-backup snapshots

down removes containers, not volumes. Players are disconnected during the restart (a few minutes); they reconnect once minecraft is healthy again.

Prerequisites (one-time, on cochi)

  • SSH access as the cochi alias.
  • .env present and complete: BASE_DOMAIN, RCON_PASSWORD, CADDY_HTTP_PORT, CADDY_HTTP_BIND, DISTRIBUTION_WEB_ROOT, and the Let's Encrypt block (render-config.sh halts on an unset BASE_DOMAIN).
  • Docker + compose plugin, packwiz, envsubst, git.
  • Host nginx + Let's Encrypt certs installed once — see 15-letsencrypt.md.
  • First deploy only — online prep (build landing, fetch launcher, fetch authlib into runtime/). Not needed for routine redeploys.

Verify

docker compose ps      # caddy, drasl, minecraft, mc-backup, nmsr, uptime-kuma up
docker compose logs -f minecraft   # watch for "Done"
curl -fsS "https://auth.$(grep '^BASE_DOMAIN=' .env | cut -d= -f2)/" >/dev/null && echo "auth ok"

Rollback

git log --oneline -5            # find the last-good commit
git checkout <sha>              # or: git reset --hard <sha>
docker compose down --remove-orphans
docker compose up -d --build

Notes

  • Production needs internet on cochi at restart: the server installs/re-syncs NeoForge + mods over the network.
  • All ingress goes through host nginx → caddy. After a redeploy, nginx config is unchanged; only re-run tooling/render-nginx.sh --install if BASE_DOMAIN / CADDY_HTTP_PORT changed (see 15-letsencrypt.md).
