# Ulicraft Server
|
||
|
||
Self-hosted modded Minecraft (NeoForge 1.21.1) for a LAN party. Runs **online**
|
||
(internet present) or **fully air-gapped** (offline). Self-hosted auth/skins
|
||
(Drasl), a packwiz modpack, a guest landing page, and a transparent mirror of
|
||
Mojang/launcher/NeoForge assets so guest laptops need no internet.
|
||
|
||
## Stack
|
||
|
||
| Service | Image | Role |
|
||
|---|---|---|
|
||
| `minecraft` | itzg/minecraft-server | NeoForge 1.21.1 server, `:25565` |
|
||
| `drasl` | unmojang/drasl | Yggdrasil auth + skins (password login) |
|
||
| `caddy` | caddy:alpine | ingress: landing, auth/packwiz proxy, asset mirror (`tls internal`) |
|
||
| `mc-backup` | itzg/mc-backup | world backups every 6h via RCON |
|
||
|
||
Optional layers: `avahi` (mDNS `.local`), `dnsmasq` (turnkey DNS) — only if you
|
||
don't run your own DNS.
|
||
|
||
Config lives in `.env`: `BASE_DOMAIN` (default `ulicraft.lan`), `HOST_LAN_IP`,
|
||
`RCON_PASSWORD`, `ENABLE_MDNS`. Services are subdomains: `auth.`, `packwiz.`,
|
||
`mc.`, plus the apex landing page.
|
||
|
||
## DNS (pick one)
|
||
|
||
Names must resolve to `HOST_LAN_IP`. Use **your own party DNS server** (recommended):
|
||
|
||
```sh
|
||
tooling/dns-records.sh online # service names only (internet present)
|
||
tooling/dns-records.sh airgap # + Mojang/launcher/NeoForge spoofs (offline)
|
||
```
|
||
Paste the printed records into your DNS. **Use `.lan`, not `.local`** — `.local`
|
||
is intercepted by mDNS and won't resolve via unicast DNS.
|
||
|
||
Alternatives: `ENABLE_MDNS=true` + `BASE_DOMAIN=*.local` (zero-config mDNS,
|
||
macOS/Linux native, Windows needs Bonjour) — but mDNS can't serve the air-gap
|
||
upstream spoofs. Or layer in `docker-compose.dnsmasq.yml` for a turnkey DNS.
|
||
|
||
## Prerequisites
|
||
|
||
Docker + Docker Compose; for prep also `pnpm`, `packwiz`, `jq`, `curl`,
|
||
`envsubst`, `sha1sum`.
|
||
|
||
## Launch
|
||
|
||
```sh
|
||
cp .env.example .env # set BASE_DOMAIN, HOST_LAN_IP, RCON_PASSWORD
|
||
|
||
tooling/build-stack.sh --prep # ONLINE, once: render, build landing,
|
||
# mirror mods+assets, fetch launcher +
|
||
# authlib, pre-bake the server volume
|
||
|
||
tooling/build-stack.sh --up online # internet present, no mirror
|
||
tooling/build-stack.sh --up airgap # offline; full asset mirror on :443 (default)
|
||
tooling/build-stack.sh --up core # base only (debugging)
|
||
```
|
||
|
||
`--up` prints the DNS records to add for that mode. Down:
|
||
`docker compose -f docker-compose.yml -f docker-compose.static.yml -f docker-compose.mirror.yml down`
|
||

||
## Join (guests)
|
||
|
||
1. Open `http://ulicraft.lan`, download FjordLauncherUnlocked for your OS.
|
||
2. Add an **authlib-injector** account, URL `http://auth.ulicraft.lan/authlib-injector`
|
||
(register/login at `http://auth.ulicraft.lan`).
|
||
3. **Air-gap only:** trust the local CA — download `http://ulicraft.lan/ca.crt`
|
||
and add it to your OS trust store (so the HTTPS asset mirror is trusted).
|
||
4. Import the pack: `http://packwiz.ulicraft.lan/pack.toml`.
|
||
5. Connect to **`mc.ulicraft.lan`** (no port needed).
