# Deploy to the Ubuntu VM (all-in-one) — LAN / HTTP

Everything runs on **one Ubuntu VM, one Docker daemon**: Gitea, the container
registry, the build, and the ROLAC runtime. So a single Gitea Actions job (the
`ubuntu` runner) does the whole pipeline — no cross-machine pull, no Windows-runner
quirks.

```
git push main
   │
   ▼
Gitea (on the VM)  ── triggers .gitea/workflows/ci-cd-vm.yml
   │
   ▼
ubuntu runner (on the VM, same Docker daemon)
   dotnet test
   docker build ./API + ./APP      -> :latest + :<sha>
   docker push                     -> git.golife.love/chrischen/rolac-{api,app}
   docker compose up -d (TAG=<sha>)
   curl /api/health
   │
   ▼
browser  ->  http://<vm-ip>:8080
                 │ nginx edge (container, 8080->80)
                 ├── /        -> app container (Angular static)
                 └── /api/    -> api container (ASP.NET, :8080)
api  ──> existing PostgreSQL @ 192.168.68.55:49154   (not containerized)
```

No TLS yet — plain HTTP on port **8080**. Add Let's Encrypt later (see the Azure
`deploy/` files) or front it with an existing reverse proxy.

## One-time setup — on the VM

1. **Deploy dir + secrets:**
   ```bash
   sudo mkdir -p /home/chris/docker/rolac/nginx/conf.d /home/chris/docker/rolac/data/api-storage
   sudo cp /path/to/repo/deploy/vm/.env.example /home/chris/docker/rolac/.env
   sudo nano /home/chris/docker/rolac/.env    # real DB user/password + JWT_SECRET + APP_ORIGIN
   ```
   Make sure the user the runner executes as can read/write `/home/chris/docker/rolac`.

2. **Registry token** — in Gitea: Settings → Applications → new token with
   `read:package` + `write:package`. Log Docker in once on the VM:
   ```bash
   docker login git.golife.love -u ChrisChen   # paste the token
   ```

3. **Install act_runner on the VM** with the label **`ubuntu`** and access to the
   host Docker. The runner must be able to run `dotnet`, `docker`, and
   `docker compose`, and reach `/home/chris/docker/rolac`:
   ```bash
   docker run -d --restart unless-stopped --name rolac-runner \
     -v /var/run/docker.sock:/var/run/docker.sock \
     -v /home/chris/docker/rolac:/home/chris/docker/rolac \
     -e GITEA_INSTANCE_URL=https://git.golife.love \
     -e GITEA_RUNNER_REGISTRATION_TOKEN=<token> \
     -e GITEA_RUNNER_LABELS=ubuntu \
     gitea/act_runner:latest
   ```
   > The job calls `dotnet test` and `docker build` directly. If act_runner runs in
   > a container, that image needs the .NET 8 SDK + docker CLI on PATH. Simplest:
   > install act_runner as a **native binary** on the VM (it then uses the host's
   > Docker + an installed .NET SDK). Either way the label must be `ubuntu`.

4. **Gitea repo secrets** (Settings → Actions → Secrets):
   - `REGISTRY_USER` = `ChrisChen`
   - `REGISTRY_TOKEN` = the package token from step 2

5. **Enable Actions** for the repo if needed (Settings → Advanced → Actions).

## Day-to-day

`git push` to `main` → `.gitea/workflows/ci-cd-vm.yml`:
**test → build both images → push to registry → sync compose/nginx → `compose up -d` → health check.**

Open `http://<vm-ip>:8080` and log in.

Deploy pins `TAG=<git-sha>`, so the running containers match exactly the commit that
was built (the images already exist in the local Docker, so this is instant).

---

## Manual deploy (no runner yet)

On the VM, from a checkout of the repo:
```bash
docker login git.golife.love -u ChrisChen
docker build -t git.golife.love/chrischen/rolac-api:latest ./API
docker build -t git.golife.love/chrischen/rolac-app:latest ./APP
mkdir -p /home/chris/docker/rolac/nginx/conf.d /home/chris/docker/rolac/data/api-storage
cp deploy/vm/docker-compose.yml      /home/chris/docker/rolac/docker-compose.yml
cp deploy/vm/nginx/conf.d/rolac.conf /home/chris/docker/rolac/nginx/conf.d/rolac.conf
cd /home/chris/docker/rolac && docker compose up -d
curl -fsS http://localhost:8080/api/health
```

## Notes

- **First boot runs DB migrations** against `192.168.68.55` automatically
  (`Program.cs` calls `MigrateAsync()` + seed). The VM must reach that host and the
  DB user needs DDL rights; back up before the first run.
- **Uploaded files** persist under `/home/chris/docker/rolac/data/api-storage`.
- **Same Docker daemon for build + run** means `docker compose up` finds the freshly
  built `:<sha>` images locally; `docker compose pull` is unnecessary here (but
  harmless if you add it).
- To go HTTPS later: switch the edge to ports 80/443 and mount Let's Encrypt certs,
  or use the Azure `deploy/` files which already include certbot.
