# Deploy Meshkee CMS API (Debian VM)

Stack: Docker (Postgres + Redis) → Node build on server → PM2 → Nginx + Let's Encrypt.

App path on server: `/opt/meshkee/app`

API domain: `api.meshkee.com` → `https://api.meshkee.com/api/v1`

Per-business API aliases (same Nest app on this VM): `api.{apex}` e.g. `api.sanihome.ir` → `https://api.sanihome.ir/api/v1`. Storefronts still pass the **website apex** in paths (`/tenants/sanihome.ir/...`); only the API hostname changes.

> **Deploy path:** push to `git.meshkee.com` (`Meshkee/backend`), then on the API VM `git fetch` + `reset --hard origin/main` + build + `pm2 restart`. Do **not** rsync the app as the normal update path. The API VM uses a read-only SSH deploy key (`meshkee-api-vm-deploy`). Pin `sharp@0.33.5` — this VM CPU lacks x64-v2 required by sharp 0.35+.

## Prerequisites

- Debian VM with SSH access
- Domain `A` record pointing at the VM (for HTTPS)
- Git remote with this codebase (private repo → deploy key)
- Production secrets (JWT, Postgres password, S3 keys)

## 1. Server packages

```bash
sudo apt update && sudo apt upgrade -y
sudo apt install -y ca-certificates curl gnupg git nginx ufw

# Docker
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
sudo usermod -aG docker "$USER"
# log out/in (or newgrp docker) so docker works without sudo

# Node.js 20 LTS
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs
sudo npm install -g pm2

# Certbot (after Nginx is installed)
sudo apt install -y certbot python3-certbot-nginx
```

Firewall:

```bash
sudo ufw allow OpenSSH
sudo ufw allow 'Nginx Full'
sudo ufw --force enable
```

## 2. Clone the app

```bash
sudo mkdir -p /opt/meshkee
sudo chown "$USER:$USER" /opt/meshkee
cd /opt/meshkee
git clone <YOUR_GIT_REMOTE_URL> app
cd app
```

Private repo: create an SSH deploy key on the VM (`ssh-keygen -t ed25519 -C "meshkee-deploy"`), add the public key as a read-only deploy key on GitHub/GitLab, clone via SSH URL.

## 3. Production env

```bash
cp .env.example .env
nano .env   # set strong secrets — never commit this file
```

Required production values:

- Strong `POSTGRES_PASSWORD` and matching `DATABASE_URL`
- Long random `JWT_ACCESS_SECRET` / `JWT_REFRESH_SECRET`
- Real `S3_ACCESS_KEY_ID` / `S3_SECRET_ACCESS_KEY`
- `PORT=3000`
- `SMS_ENABLED` as needed

## 4. Database + Redis

```bash
cd /opt/meshkee/app
docker compose up -d
docker compose ps
```

First Postgres volume init runs SQL under `database/migrations/` automatically.

Later schema updates:

```bash
./database/migrate.sh
```

## 5. Build and run (on the server)

```bash
cd /opt/meshkee/app
npm ci
npm run prisma:generate
npm run build
```

Production seed (super admin only — skip sample data):

```bash
./database/seed.sh database/seeds/002_super_admin_user.sql
# optional reference data:
# ./database/seed.sh database/seeds/004_iran_cities.sql
# ./database/seed.sh database/seeds/005_business_categories.sql
```

Start with PM2:

```bash
pm2 start ecosystem.config.js
pm2 save
pm2 startup   # run the command it prints (usually with sudo)
```

Health check locally on the VM:

```bash
curl -s http://127.0.0.1:3000/api/v1/ | head
# or hit a known public route such as tenant resolve
```

## 6. Nginx + HTTPS

### DNS (per business website domain)

On the **business domain** DNS (e.g. zone `sanihome.ir`), add a subdomain that points at this **API VM** (same target as `api.meshkee.com`):

| Type | Name / host | Value | Notes |
|------|-------------|-------|--------|
| **A** (preferred) | `api` | `<API_VM_PUBLIC_IP>` | Resolves `api.sanihome.ir` → API server |
| **CNAME** (alternative) | `api` | `api.meshkee.com` | Same effect if your DNS panel allows CNAME on subdomains |

Do **not** point `api.{apex}` at the websites VM or dashboards VM — only the Nest API VM.

Repeat for each storefront apex (`api.ali-mohammadi.ir`, etc.). Central Meshkee DNS already has `api.meshkee.com` → this VM.

### Nginx

Create `/etc/nginx/sites-available/meshkee-api`:

```nginx
server {
    listen 80;
    # Central + per-business aliases (add more api.{apex} as domains go live)
    server_name api.meshkee.com api.sanihome.ir;

    client_max_body_size 15M;

    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
```

Enable and get certificates:

```bash
sudo ln -sf /etc/nginx/sites-available/meshkee-api /etc/nginx/sites-enabled/
sudo rm -f /etc/nginx/sites-enabled/default
sudo nginx -t && sudo systemctl reload nginx
sudo certbot --nginx -d api.meshkee.com -d api.sanihome.ir
# later, when another business goes live:
# sudo certbot --nginx -d api.meshkee.com -d api.sanihome.ir -d api.other-site.ir
```

API base URLs (identical Nest routes):

- Central: `https://api.meshkee.com/api/v1`
- Alias example: `https://api.sanihome.ir/api/v1`

### Website API docs (global link for storefront teams)

After deploy, these are public (no auth):

- Hub: `https://api.meshkee.com/docs/website`
- OpenAPI: `https://api.meshkee.com/docs/website/openapi.json`
- Postman: `https://api.meshkee.com/docs/website/Meshkee-Website-API.postman_collection.json`
- AI brief: `https://api.meshkee.com/docs/website/AI_PROMPT.md`

Files live in `docs/website-api/` and are served by Nest from process cwd. Keep that folder on the VM when deploying.

### Automated cert host list (API VPS)

After deploy, a sync agent on this VM can pull names to cover:

```bash
curl -s -H "X-SSL-Sync-Token: $SSL_SYNC_TOKEN" \
  https://api.meshkee.com/api/v1/internal/ssl/api-hosts
# → { "hosts": ["api.ali-mohammadi.ir", "api.meshkee.com", "api.sanihome.ir", ...] }
```

Dashboards VPS keeps using `GET /api/v1/internal/ssl/hosts` (`business.` / `customer.` / `manage`) — do not mix the two lists.

## Ongoing updates (git only)

From your laptop:

1. Commit and **push** to `origin/main` (`git.meshkee.com/Meshkee/backend`).
2. Deploy on the API VM from that commit (never rsync the tree as the primary path):

```bash
ssh -i ~/.ssh/id_ed25519 root@185.164.72.119 'bash -s' <<'REMOTE'
set -euo pipefail
cd /opt/meshkee/app
git fetch origin
git reset --hard origin/main
./database/migrate.sh
npm ci
npm run prisma:generate
npm run build
pm2 restart meshkee-api
REMOTE
```

Preserve `/opt/meshkee/app/.env` on the server. App remote must be SSH: `git@git.meshkee.com:Meshkee/backend.git` with the VM deploy key registered as a **read-only deploy key** on the repo.

## Useful commands

```bash
pm2 status
pm2 logs meshkee-api
docker compose logs -f postgres
```
