The server JVM agent (runtime/authlib-injector.jar, mounted at /extras) is gitignored and was previously fetched by the deleted build-stack.sh prep. A fresh checkout had no jar, so minecraft crashlooped with "Error opening zip file or JAR manifest missing". Add a standalone fetch tool: resolves the latest release asset, downloads, and verifies it's a real zip/jar (PK magic) before trusting it. Idempotent (skips if valid, --force to re-download). Wire it into the deploy skill and README launch steps. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

description: Redeploy the Ulicraft Minecraft stack to the production host `cochi` — git pull on main then a hard restart (compose down + up). Use when the user says "deploy", "redeploy", "deploy to cochi", "push to prod", "ship it", or "restart the server" for this project. Causes brief Minecraft downtime.

# Deploy Ulicraft to `cochi`
|
|
|
|
Redeploy the running stack on the production host. Full reference:
|
|
`plan/14-deploy.md`.
|
|
|
|
## Fixed parameters
|
|
|
|
- Host: `cochi` (SSH alias)
|
|
- Path: `/home/ubuntu/mc/ulicraft-server-v1`
|
|
- Branch: `main`
|
|
- Stack: single unified `docker-compose.yml` (drasl, minecraft, mc-backup,
|
|
caddy, nmsr, uptime-kuma)
|
|
- Auth: Drasl
|
|
- Restart: **hard** (down → up) — players are disconnected for a few minutes
|
|
|
|
## Procedure
|
|
|
|
This is an outward-facing, downtime-causing action on production. The user
|
|
invoking this skill is the authorization to proceed, but:
|
|
|
|
1. **Pre-check (read-only).** See what would change before tearing anything down:
|
|
```bash
|
|
ssh cochi 'cd /home/ubuntu/mc/ulicraft-server-v1 && git fetch && git log --oneline HEAD..@{u}'
|
|
```
|
|
Report the incoming commits. If the list is empty, tell the user the host is
|
|
already up to date and ask whether to restart anyway (they may want a plain
|
|
restart). If `git fetch` fails (host unreachable, auth), STOP and report.
|
|
|
|
2. **Pull + hard restart** (single SSH session, halts on any error):
|
|
```bash
|
|
ssh cochi 'set -e
|
|
cd /home/ubuntu/mc/ulicraft-server-v1
|
|
git pull --ff-only
|
|
tooling/render-config.sh
|
|
tooling/fetch-authlib.sh
|
|
docker compose down --remove-orphans
|
|
docker compose up -d --build'
|
|
```
|
|
- `--ff-only` refuses to merge — if the pull is not a fast-forward, STOP and
|
|
report (local changes on the host need manual resolution).
|
|
- `render-config.sh` re-renders drasl/nmsr/packwiz configs from `.env`
|
|
(needs `.env` complete: `BASE_DOMAIN`, `RCON_PASSWORD`,
|
|
`DISTRIBUTION_WEB_ROOT`, `CADDY_HTTP_*`).
|
|
- `fetch-authlib.sh` ensures `runtime/authlib-injector.jar` exists (gitignored;
|
|
skips if already valid). Missing jar = minecraft crashloops with "Error
|
|
opening zip file or JAR manifest missing".
|
|
|
|
3. **Verify.**
|
|
```bash
|
|
ssh cochi 'cd /home/ubuntu/mc/ulicraft-server-v1 && docker compose ps'
|
|
```
|
|
Confirm `caddy`, `drasl`, `minecraft`, `mc-backup`, `nmsr`, `uptime-kuma` are
|
|
Up. Tail the minecraft log briefly and confirm it reaches `Done` (server
|
|
ready):
|
|
```bash
|
|
ssh cochi 'cd /home/ubuntu/mc/ulicraft-server-v1 && timeout 120 docker compose logs -f minecraft' 2>/dev/null | grep -m1 "Done"
|
|
```
|
|
|
|
## Guardrails
|
|
|
|
- Never `git reset --hard` or discard changes on `cochi` without telling the user
|
|
first — there may be host-local edits.
|
|
- Volumes (`mc_data`, `drasl_state`, `kuma_data`) persist across `down`; the
|
|
world and monitors are safe. Do NOT pass `-v`/`--volumes` to `down`.
|
|
- If a step fails, STOP and surface the exact error + the failing command. Do not
|
|
improvise recovery on production.
