# Deploy Warmbox with Nginx Proxy Manager (Docker)

Warmbox runs as one container on your existing **`npm_network`**. Nginx Proxy Manager (NPM) terminates HTTPS and forwards to `http://warmbox:3000`.

```text
Internet → warmbox.jonnyn.com (DNS) → NPM :443 → warmbox:3000 (Docker network)
```

No host port is published. Warmbox can run alongside `homepage` on host port 3000 — they do not conflict.

---

## Prerequisites

- Ubuntu server with Docker + Compose v2
- [Nginx Proxy Manager](https://nginxproxymanager.com/) already running on Docker network **`npm_network`**
- DNS **A** record: `warmbox.jonnyn.com` → your home public IP
- Router forwards **80** and **443** to NPM (if not already)

Confirm NPM’s network name:

```bash
docker network ls | grep npm
docker inspect <npm-container-name> --format '{{json .NetworkSettings.Networks}}' | jq
```

If your network is not `npm_network`, edit `networks.default.name` in `docker-compose.yml`.

---

## 1. Clone and configure

```bash
cd /srv/docker-configs/warmbox   # or your path
git pull                         # get latest docker-compose.yml

cp .env.example .env
nano .env
```

Required variables:

```bash
ENCRYPTION_KEY=<openssl rand -hex 32>   # never change after first deploy
API_KEY=<openssl rand -hex 24>          # dashboard login
PUBLIC_BASE_URL=https://warmbox.jonnyn.com
AI_API_KEY=sk-or-v1-...
```

**Migrating from your Mac:** use the **same** `ENCRYPTION_KEY` and copy `prisma/dev.db` (see §6).

---

## 2. Start Warmbox

```bash
cd /srv/docker-configs/warmbox

# Stop any old stack (including previous compose overrides)
docker compose down

# Build and start — joins npm_network automatically
docker compose up -d --build
```

Verify:

```bash
docker compose ps
docker compose logs -f warmbox
```

Warmbox should be **healthy**. Check it is on `npm_network`:

```bash
docker inspect warmbox --format '{{range $k,$v := .NetworkSettings.Networks}}{{$k}} {{end}}'
# should include: npm_network
```

Test from another container on the same network (e.g. NPM):

```bash
docker exec -it <npm-app-container> wget -qO- http://warmbox:3000/health
# expect: {"status":"ok"}
```

---

## 3. Nginx Proxy Manager — proxy host

Open NPM UI (usually `http://<server-ip>:81`).

**Hosts → Proxy Hosts → Add Proxy Host**

| Tab / field | Value |
|-------------|--------|
| Domain names | `warmbox.jonnyn.com` |
| Scheme | `http` |
| Forward hostname / IP | `warmbox` |
| Forward port | `3000` |
| Cache assets | off |
| Block common exploits | on |
| Websockets support | on |

**SSL** tab:

- SSL Certificate: Request a new Let's Encrypt certificate
- Force SSL: on
- HTTP/2: on

If Cloudflare proxies your A record (orange cloud), set Cloudflare SSL mode to **Full** or **Full (strict)**.

Save, then test:

```bash
curl -s https://warmbox.jonnyn.com/health
```

---

## 4. Dashboard login

1. Open `https://warmbox.jonnyn.com`
2. Enter `API_KEY` from `.env`
3. Leave **Base URL** empty (same origin in production)

---

## 5. OAuth redirect URIs

Update in Google Cloud / Azure if you use these integrations:

| Integration | Redirect URI |
|-------------|----------------|
| Google Postmaster | `https://warmbox.jonnyn.com/api/integrations/google/callback` |
| Microsoft Outlook | `https://warmbox.jonnyn.com/api/integrations/microsoft/callback` |

---

## 6. Migrate local database (optional)

```bash
# On your Mac
scp prisma/dev.db jonnyn@burke:/tmp/warmbox.db

# On server
cd /srv/docker-configs/warmbox
docker compose down
docker run --rm -v warmbox_warmbox-data:/data -v /tmp:/backup alpine \
  cp /backup/warmbox.db /data/warmbox.db
docker compose up -d
```

Use the same `ENCRYPTION_KEY` as on your Mac.

---

## 7. Day-to-day commands

```bash
cd /srv/docker-configs/warmbox

docker compose logs -f warmbox          # live logs
docker compose up -d --build              # rebuild after git pull
docker compose down                       # stop
docker compose restart warmbox            # restart app only

# Backup SQLite
docker compose exec warmbox sh -c 'cp /data/warmbox.db /data/warmbox-$(date +%F).db'
```

---

## Troubleshooting

### `port 3000 already allocated`

Your `docker-compose.yml` must **not** have a `ports:` section under `warmbox`:

```bash
grep ports docker-compose.yml
# should return nothing (or only comments)
```

Warmbox uses port 3000 **inside** the container only. `homepage` on host `0.0.0.0:3000` is unrelated.

### NPM 502 Bad Gateway

1. Warmbox running and healthy: `docker compose ps`
2. On `npm_network`: `docker inspect warmbox --format '{{json .NetworkSettings.Networks}}'`
3. NPM forward host is `warmbox` (not `localhost`, not `127.0.0.1`)
4. NPM forward port is `3000`
5. Logs: `docker compose logs warmbox`

### `network npm_network not found`

Create it or fix the name to match NPM:

```bash
docker network ls
# edit docker-compose.yml → networks.default.name
```

### Login fails

- `API_KEY` in `.env` must match what you type
- Restart after `.env` change: `docker compose up -d --force-recreate`

### Container unhealthy

```bash
docker compose logs warmbox
```

Common causes: missing `ENCRYPTION_KEY`, bad `DATABASE_URL`, migration error.

## Why only `npm_network`?

NPM and Warmbox must share a Docker network so NPM can resolve the hostname `warmbox`. A separate `warmbox_internal` network is unnecessary for this setup — one external network is enough.
