# Deploying the app

End-to-end runbook: domain → DNS → server → live, plus Google login.

This document is written to be executed in order. Steps marked **[you]** require
logging into a third-party account (Cloudflare, GoDaddy, Google) — those must be
done by a human; they are not automated here. Steps marked **[server]** run on
the host over SSH.

---

## ⚠️ FIRST: confirm the domain name

The request said **`buildmymcp.com`**. But the open GoDaddy tab and this
repository are both named **`buildmymcpserver.com`** — that is the domain you
appear to actually own.

**These are two different domains.** Decide which one before doing anything:

- If the live domain is **`buildmymcpserver.com`** — do a find-and-replace of
  `buildmymcp.com` → `buildmymcpserver.com` across this file and
  `.env.production.example` before you start. `api.buildmymcp.com` becomes
  `api.buildmymcpserver.com`, etc.
- If you intend to register and use the shorter **`buildmymcp.com`** — register
  it at GoDaddy first, then this file is correct as written.

Every hostname below uses `buildmymcp.com` as a placeholder. It must match the
domain you put into Cloudflare in step 1.

## 0. What you are deploying

Five services, defined in `docker-compose.prod.yml`:

| Service     | Role                                              | Network        |
|-------------|---------------------------------------------------|----------------|
| `postgres`  | Primary database                                  | bridge → loopback |
| `redis`     | Queue + cache                                     | bridge → loopback |
| `api`       | Fastify control plane + OAuth server (port 4000)  | host           |
| `generator` | BullMQ worker — builds & runs generated MCP images| host           |
| `web`       | Next.js front end (port 3001)                     | host           |

`api` and `generator` mount the Docker socket: the API removes generated
containers, the generator builds and runs them as host siblings on ports
4100–4999.

**The stack binds nothing on ports 80/443.** It is safe to run alongside the
other apps already on the box. A reverse proxy terminates TLS in front of it
(step 7).

### Server

Per `~/Desktop/DayZ/server_remote/README.md`, the box is a Hetzner machine at
`213.239.213.217`, Linux, root SSH. **Other production apps already run on it —
treat ports 80/443 and existing services as occupied until proven otherwise.**

> **Gitea / pipeline — unverified.** The request mentioned deploying "via the
> Gitea pipeline like the other projects." Nothing in the repo or the DayZ
> server repo confirms Gitea runs on this box, and the DayZ deploy workflow
> there is a manual `scp` + `systemctl` flow with no CI. Step 6 below gives a
> Gitea path **and** a plain `git`/`rsync` path — use whichever matches what is
> actually installed. Confirm with `ssh root@213.239.213.217 "docker ps | grep -i gitea"`.

## 1. Cloudflare — create the zone **[you]**

1. Log in to <https://dash.cloudflare.com> (your account — do this yourself).
2. **Add a site** → `buildmymcp.com` → pick the **Free** plan.
3. Cloudflare scans existing DNS. **Before changing anything, write down every
   record it finds.** If `buildmymcp.com` currently points anywhere, those
   records must be recreated here or that service goes dark.
4. Note the **two nameservers** Cloudflare assigns (e.g. `xxx.ns.cloudflare.com`).
   You need them in step 3.

### DNS records to create in Cloudflare

| Type | Name  | Content              | Proxy        |
|------|-------|----------------------|--------------|
| A    | `@`   | `213.239.213.217`    | Proxied (🟠) |
| A    | `api` | `213.239.213.217`    | Proxied (🟠) |
| A    | `www` | `213.239.213.217`    | Proxied (🟠) |

> If you issue TLS certificates with Let's Encrypt HTTP-01 (step 7, optional
> Traefik), set the records to **DNS only (grey cloud)** first, issue the cert,
> then switch to **Proxied**. With a Cloudflare Origin Certificate this is not
> needed — see step 7.

**SSL/TLS mode:** set to **Full (strict)** once the origin has a real
certificate. Use **Full** in the interim. Never use **Flexible**.

---

## 2. ⚠️ Order of operations — read before step 3

The single way this deploy can take a site offline:

> **Recreate ALL existing DNS records in Cloudflare (step 1) BEFORE changing the
> nameservers at GoDaddy (step 3).**

Once GoDaddy points at Cloudflare, Cloudflare's zone becomes authoritative.
Anything not copied into it stops resolving — email (MX), other subdomains,
verification TXT records, everything. Copy first, switch second.

---

## 3. GoDaddy — point the domain at Cloudflare **[you]**

Only after step 1's records exist in Cloudflare:

1. Log in to <https://dcc.godaddy.com> (your account — do this yourself).
2. Find `buildmymcp.com` → **Domain Settings** → **Nameservers** → **Change**.
3. Choose **Enter my own nameservers (custom)**.
4. Replace GoDaddy's nameservers with the two from Cloudflare (step 1.4).
5. Save. Propagation is usually minutes, up to 24 h.
6. Cloudflare's dashboard shows the zone as **Active** when it has taken over.

---

## 4. Server prep **[server]**

```bash
ssh root@213.239.213.217

# Docker + compose plugin (skip any that are already present)
docker --version || curl -fsSL https://get.docker.com | sh
docker compose version

# Confirm what already uses 80/443 — do NOT disturb it
ss -ltnp '( sport = :80 or sport = :443 )'
```

Firewall: only `22`, `80`, `443` should be open to the internet. The app ports
(`3001`, `4000`, `5440`, `6390`) must stay private — they are reachable only
over loopback / the proxy.

---

## 5. Get the code onto the server **[server]**

Pick the path that matches the box.

**Option A — Gitea pipeline** (only if Gitea is actually installed):
push this repo to the Gitea instance, then have its Actions runner (or your
existing deploy pipeline) check out the repo to `/opt/buildmymcp` and run the
commands in step 6. Mirror whatever the other projects on this box already do.

**Option B — plain git / rsync** (always works):

```bash
mkdir -p /opt/buildmymcp
# from your workstation:
rsync -az --delete --exclude node_modules --exclude .git \
  ~/Desktop/buildmymcpserver.com/ root@213.239.213.217:/opt/buildmymcp/
```

---

## 6. Configure and start the stack **[server]**

```bash
cd /opt/buildmymcp

# 1. Create the production env file from the template
cp .env.production.example .env.production
openssl rand -hex 32      # paste into SECRETS_ENCRYPTION_KEY
nano .env.production      # fill every CHANGE-ME value

# 2. Build and start
docker compose --env-file .env.production -f docker-compose.prod.yml up -d --build

# 3. Push the database schema (one-time, and after any schema change)
docker compose --env-file .env.production -f docker-compose.prod.yml \
  exec api pnpm --filter @bmm/db push

# 4. Watch it come up
docker compose --env-file .env.production -f docker-compose.prod.yml ps
docker compose --env-file .env.production -f docker-compose.prod.yml logs -f api
```

`.env.production` values that must be correct before first boot:

- `SECRETS_ENCRYPTION_KEY` — real 32-byte hex. The API **refuses to boot** in
  production on the all-zero placeholder.
- `DATABASE_URL` password must match `POSTGRES_PASSWORD`.
- `NEXT_PUBLIC_API_URL` is compiled into the web bundle — rebuild `web` if you
  change it (`up -d --build web`).
- `ANTHROPIC_API_KEY` — empty runs mock generation; set it for real Claude output.

Health check: `curl http://127.0.0.1:4000/health` → `{"ok":true,...}`.

---

## 7. Reverse proxy + TLS **[server]**

**First: is there already a proxy?**

```bash
ss -ltnp '( sport = :80 or sport = :443 )'
```

- **Something already listens** (the other live apps' proxy): add two vhosts to
  that proxy and **skip the Traefik option**:
  - `buildmymcp.com`, `www.buildmymcp.com` → `http://127.0.0.1:3001`
  - `api.buildmymcp.com` → `http://127.0.0.1:4000`

- **Nothing listens** on 80/443: use the optional Traefik in `infra/traefik/`:

  ```bash
  cd /opt/buildmymcp/infra/traefik
  cp .env.example .env          # set ACME_EMAIL
  docker compose --env-file .env -f docker-compose.traefik.yml up -d
  ```

  `dynamic.yml` already routes the three hostnames to the loopback ports.

> **Let's Encrypt + Cloudflare:** HTTP-01 issuance works most reliably while the
> Cloudflare records are **DNS only (grey cloud)**. Issue the cert, confirm
> HTTPS, then flip the records to **Proxied (orange)**.
> Alternative: generate a **Cloudflare Origin Certificate** (15-year, in the
> Cloudflare dashboard → SSL/TLS → Origin Server), drop the cert + key into the
> proxy, and skip ACME entirely. Then set Cloudflare SSL to **Full (strict)**.

> **Generated MCP servers** currently get a `http://RUNNER_HOST:<port>` URL and
> are not yet routed through the proxy by subdomain. Wiring `*.mcp.buildmymcp.com`
> to the dynamic runner ports is a follow-up before opening generated servers to
> the public internet.

## 8. Google login — Google Cloud Console **[you]**

1. Log in to <https://console.cloud.google.com> (your account — do this yourself).
2. **Create a project** — e.g. `buildmymcp`.
3. **APIs & Services → OAuth consent screen:**
   - User type: **External**.
   - App name `BuildMyMCP`, support email, developer contact.
   - Scopes: `openid`, `.../auth/userinfo.email`, `.../auth/userinfo.profile`.
   - Add yourself as a **test user**, or **Publish** the app for public sign-in.
4. **APIs & Services → Credentials → Create credentials → OAuth client ID:**
   - Application type: **Web application**.
   - **Authorized redirect URI** — must be exact:
     ```
     https://api.buildmymcp.com/v1/auth/google/callback
     ```
   - (For local testing also add `http://localhost:4000/v1/auth/google/callback`.)
5. Copy the **Client ID** and **Client secret** into `.env.production`:
   ```
   GOOGLE_OAUTH_ID=...apps.googleusercontent.com
   GOOGLE_OAUTH_SECRET=...
   ```
6. Restart the API so it picks them up:
   ```bash
   docker compose --env-file .env.production -f docker-compose.prod.yml up -d api
   ```

The redirect URI is derived from `CONTROL_PLANE_PUBLIC_URL`. If that is not
`https://api.buildmymcp.com`, the URI registered in Google must match whatever
it is. When `GOOGLE_OAUTH_ID`/`SECRET` are set, the login page shows the
**Continue with Google** button automatically; when unset it is hidden.

---

## 9. Verify live

- `https://buildmymcp.com` — landing page loads over HTTPS.
- `https://api.buildmymcp.com/health` — `{"ok":true,...}`.
- `https://buildmymcp.com/login` — magic link **and** Continue with Google.
- Sign in with Google → lands on `/dashboard`.
- `https://buildmymcp.com/admin/login` — admin login with `ADMIN_EMAIL` /
  `ADMIN_PASSWORD`.
- Create a server in the wizard → build reaches `live`.

---

## 10. Operations

```bash
cd /opt/buildmymcp
C="docker compose --env-file .env.production -f docker-compose.prod.yml"

$C ps                       # status
$C logs -f generator        # tail a service
$C up -d --build            # redeploy after a code change
$C up -d --build web        # rebuild only web (e.g. NEXT_PUBLIC_API_URL changed)
$C restart api              # restart one service
$C down                     # stop the stack (volumes/data preserved)
```

**Rollback:** `$C down` then redeploy the previous commit. Named volumes
(`bmm_pg`, `bmm_redis`, `bmm_keys`, `bmm_build_context`) survive `down`, so data
and OAuth signing keys persist. `down -v` would destroy them — do not use it.

**Back up the database before any schema change:**

```bash
$C exec postgres pg_dump -U bmm bmm > backup-$(date +%F).sql
```

## Known follow-ups (not blockers, but track them)

1. Per-server subdomain routing (`*.mcp.buildmymcp.com`) for generated MCP
   servers — not yet wired (step 7).
2. Magic-link email is printed to the API log in all environments — wire a real
   transport (Resend / SES) before relying on email sign-in in production.
3. CI/CD: if a Gitea pipeline is adopted, the deploy step is exactly the step 6
   commands.
