## Step 1: Create Digital Ocean Droplet

### Recommended Specifications

**Minimum (Testing):**
- **Size:** Basic Droplet - $12/month
- **RAM:** 2GB
- **CPU:** 1 vCPU
- **Storage:** 50GB SSD
- **Region:** Choose closest to your users

**Recommended (Production):**
- **Size:** General Purpose - $24/month
- **RAM:** 4GB
- **CPU:** 2 vCPUs
- **Storage:** 80GB SSD
- **Region:** Choose closest to your users

### Create Droplet

1. Go to [Digital Ocean](https://cloud.digitalocean.com/droplets/new)
2. **Choose Image:** Ubuntu 24.04 LTS x64
3. **Choose Size:** Select based on recommendations above
4. **Choose Region:** Select closest region
5. **Authentication:** SSH keys (recommended) or password
6. **Hostname:** `vip-coordinator`
7. **Tags:** `production`, `vip-coordinator`
8. **Backups:** Enable weekly backups (recommended)
9. Click **Create Droplet**

## Step 2: Initial Server Setup

### SSH into Droplet

```bash
ssh root@YOUR_DROPLET_IP
```

### Update System

```bash
apt update && apt upgrade -y
```

### Create Non-Root User

```bash
adduser vipcoord
usermod -aG sudo vipcoord
usermod -aG docker vipcoord  # Will add docker group later
```

### Configure Firewall (UFW)

```bash
# Enable UFW
ufw default deny incoming
ufw default allow outgoing

# Allow SSH
ufw allow OpenSSH

# Allow HTTP and HTTPS
ufw allow 80/tcp
ufw allow 443/tcp

# Enable firewall
ufw enable

# Check status
ufw status
```

## Step 3: Install Docker

```bash
# Install Docker
curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh

# Add user to docker group
usermod -aG docker vipcoord

# Install Docker Compose
apt install docker-compose-plugin -y

# Verify installation
docker --version
docker compose version
```

## Step 4: Configure Gitea Registry Access

### Option A: Public Gitea (Recommended)

If your Gitea is publicly accessible:

```bash
# Login to Gitea registry
docker login YOUR_PUBLIC_GITEA_URL:3000 -u kyle
# Enter your Gitea token: 2f4370ce710a4a1f84e8bf6c459fe63041376c0e
```

### Option B: Gitea on LAN (Requires VPN/Tunnel)

If your Gitea is on LAN (192.168.68.53):

**Solutions:**
1. **Tailscale VPN** (Recommended)
   - Install Tailscale on both your local machine and Digital Ocean droplet
   - Access Gitea via Tailscale IP

2. **SSH Tunnel**
   ```bash
   # On your local machine
   ssh -L 3000:192.168.68.53:3000 root@YOUR_DROPLET_IP
   ```

3. **Expose Gitea Publicly** (Not Recommended for Security)
   - Configure port forwarding on your router
   - Use dynamic DNS service
   - Set up Cloudflare tunnel

### Option C: Alternative - Push to Docker Hub

If Gitea access is complex, push images to Docker Hub instead:

```bash
# On your local machine
docker tag 192.168.68.53:3000/kyle/vip-coordinator/backend:latest kyle/vip-coordinator-backend:latest
docker tag 192.168.68.53:3000/kyle/vip-coordinator/frontend:latest kyle/vip-coordinator-frontend:latest

docker push kyle/vip-coordinator-backend:latest
docker push kyle/vip-coordinator-frontend:latest
```

Then update `docker-compose.digitalocean.yml` to use Docker Hub images.

## Step 5: Deploy Application

### Copy Files to Droplet

```bash
# On your local machine
scp docker-compose.digitalocean.yml root@YOUR_DROPLET_IP:/home/vipcoord/
scp .env.digitalocean.example root@YOUR_DROPLET_IP:/home/vipcoord/
```

### Configure Environment

```bash
# On droplet
cd /home/vipcoord

# Copy and edit environment file
cp .env.digitalocean.example .env.digitalocean
nano .env.digitalocean
```

**Update these values:**
```env
# If using LAN Gitea via Tailscale
GITEA_REGISTRY=100.x.x.x:3000

# If using public Gitea
GITEA_REGISTRY=gitea.yourdomain.com:3000

# If using Docker Hub
# Comment out GITEA_REGISTRY and update image names in docker-compose

# Strong database password
POSTGRES_PASSWORD=YOUR_STRONG_PASSWORD_HERE

# Auth0 configuration (same as before)
AUTH0_DOMAIN=dev-s855cy3bvjjbkljt.us.auth0.com
AUTH0_CLIENT_ID=JXEVOIfS5eYCkeKbbCWIkBYIvjqdSP5d
AUTH0_AUDIENCE=https://vip-coordinator-api
AUTH0_ISSUER=https://dev-s855cy3bvjjbkljt.us.auth0.com/
```

### Start Services

```bash
# Start all services
docker compose -f docker-compose.digitalocean.yml --env-file .env.digitalocean up -d

# Check status
docker compose -f docker-compose.digitalocean.yml ps

# View logs
docker compose -f docker-compose.digitalocean.yml logs -f
```

## Step 6: Set Up Reverse Proxy with SSL

### Option A: Caddy (Recommended - Easiest)

Create `Caddyfile`:

```bash
nano Caddyfile
```

```caddy
your-domain.com {
    reverse_proxy localhost:80
}
```

Run Caddy:

```bash
docker run -d \
  --name caddy \
  -p 80:80 \
  -p 443:443 \
  -v /home/vipcoord/Caddyfile:/etc/caddy/Caddyfile \
  -v caddy_data:/data \
  -v caddy_config:/config \
  --restart unless-stopped \
  caddy:latest
```

Caddy automatically handles:
- SSL certificate from Let's Encrypt
- HTTP to HTTPS redirect
- Certificate renewal

### Option B: Traefik

Create `docker-compose.traefik.yml`:

```yaml
version: '3.8'

services:
  traefik:
    image: traefik:v2.10
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--entrypoints.web.address=:80"
      - "--entrypoints.websecure.address=:443"
      - "--certificatesresolvers.letsencrypt.acme.email=your@email.com"
      - "--certificatesresolvers.letsencrypt.acme.storage=/letsencrypt/acme.json"
      - "--certificatesresolvers.letsencrypt.acme.httpchallenge.entrypoint=web"
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "./letsencrypt:/letsencrypt"
    restart: unless-stopped
```

## Step 7: Configure Auth0

Update Auth0 application settings:

1. Go to [Auth0 Dashboard](https://manage.auth0.com/)
2. Select your application
3. **Allowed Callback URLs:** Add `https://your-domain.com`
4. **Allowed Web Origins:** Add `https://your-domain.com`
5. **Allowed Logout URLs:** Add `https://your-domain.com`
6. Click **Save Changes**

## Step 8: Database Backups

### Automated Daily Backups

Create backup script:

```bash
nano /home/vipcoord/backup-db.sh
```

```bash
#!/bin/bash
BACKUP_DIR="/home/vipcoord/backups"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)

mkdir -p $BACKUP_DIR

docker exec vip-coordinator-postgres pg_dump -U vip_user vip_coordinator | gzip > $BACKUP_DIR/vip_coordinator_$TIMESTAMP.sql.gz

# Keep only last 7 days
find $BACKUP_DIR -name "vip_coordinator_*.sql.gz" -mtime +7 -delete
```

Make executable and add to cron:

```bash
chmod +x /home/vipcoord/backup-db.sh

# Add to crontab (daily at 2 AM)
crontab -e
# Add this line:
0 2 * * * /home/vipcoord/backup-db.sh
```

## Step 9: Monitoring and Logging

### View Logs

```bash
# All services
docker compose -f docker-compose.digitalocean.yml logs -f

# Specific service
docker compose -f docker-compose.digitalocean.yml logs -f backend

# Last 100 lines
docker compose -f docker-compose.digitalocean.yml logs --tail=100 backend
```

### Check Container Health

```bash
docker ps
docker compose -f docker-compose.digitalocean.yml ps
```

### Monitor Resources

```bash
# Real-time resource usage
docker stats

# Disk usage
df -h
docker system df
```

## Step 10: Updating Application

When you push new images to Gitea:

```bash
# On droplet
cd /home/vipcoord

# Pull latest images
docker compose -f docker-compose.digitalocean.yml pull

# Restart with new images
docker compose -f docker-compose.digitalocean.yml down
docker compose -f docker-compose.digitalocean.yml up -d

# Verify
docker compose -f docker-compose.digitalocean.yml ps
docker compose -f docker-compose.digitalocean.yml logs -f
```

## Troubleshooting

### Application Not Accessible

1. Check firewall: `ufw status`
2. Check containers: `docker ps`
3. Check logs: `docker compose logs -f`
4. Check Auth0 callback URLs match your domain

### Database Connection Issues

```bash
# Check postgres is running
docker exec vip-coordinator-postgres pg_isready -U vip_user

# Check backend can connect
docker compose logs backend | grep -i database
```

### SSL Certificate Issues

```bash
# Caddy logs
docker logs caddy

# Force certificate renewal
docker exec caddy caddy reload --config /etc/caddy/Caddyfile
```
