# 🔥❄️ CODE-SERVER DEPLOYMENT

**Service:** Browser-based VS Code  
**Domain:** code.firefrostgaming.com  
**IP:** 74.63.218.202 (Command Center VPS)  
**Deployed:** February 11, 2026  
**Status:** ✅ OPERATIONAL

---

## What It Is

Code-Server provides full VS Code in your browser, enabling:
- Mobile editing from S24 Ultra, Chromebook, any device
- 90% reduction in SSH/terminal dependency for doc work
- Full syntax highlighting, Git integration, extensions
- Accessibility enhancement for hand limitations

---

## Architecture
```
Browser → HTTPS (74.63.218.202:443)
         → Nginx reverse proxy
         → Code-Server (localhost:8080)
         → File system access
```

**Key Features:**
- WebSocket support for real-time sync
- 24-hour session timeouts
- Password authentication (Butter2018!!)
- SSL/TLS encryption

---

## Technical Specifications

**Software:**
- Code-Server: v4.108.2
- Node.js: Built-in
- Nginx: Reverse proxy with WebSocket support

**Network:**
- Public IP: 74.63.218.202
- Internal: 127.0.0.1:8080
- Ports: 80 (HTTP redirect), 443 (HTTPS)

**Storage:**
- Config: /root/.config/code-server/config.yaml
- Data: /root/.local/share/code-server
- Workspace: /root/firefrost-work/firefrost-operations-manual

---

## Deployment Steps

### 1. DNS Configuration
- Created A record: code.firefrostgaming.com → 74.63.218.202
- Grey cloud (DNS only) for WebSocket compatibility

### 2. Installation
```bash
curl -fsSL https://code-server.dev/install.sh | sh
```

### 3. Configuration
```yaml
bind-addr: 127.0.0.1:8080
auth: password
password: Butter2018!!
cert: false
```

### 4. Systemd Service
```bash
systemctl enable --now code-server@root
```

### 5. Nginx Reverse Proxy
- WebSocket headers configured
- 24-hour timeouts for long sessions
- IP-specific binding (74.63.218.202)

### 6. SSL Certificate
```bash
certbot --nginx -d code.firefrostgaming.com
```
- Manual IP correction required (certbot defaults to primary IP)

### 7. Frostwall Rules
```bash
ufw allow in on ens3 to 74.63.218.202 port 80 proto tcp
ufw allow in on ens3 to 74.63.218.202 port 443 proto tcp
```

---

## Configuration Files

### /root/.config/code-server/config.yaml
```yaml
bind-addr: 127.0.0.1:8080
auth: password
password: Butter2018!!
cert: false
```

### /etc/nginx/sites-available/code.firefrostgaming.com
```nginx
server {
    listen 74.63.218.202:443 ssl http2;
    server_name code.firefrostgaming.com;

    ssl_certificate /etc/letsencrypt/live/code.firefrostgaming.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/code.firefrostgaming.com/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf;
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;

    location / {
        proxy_pass http://127.0.0.1:8080;
        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;

        # WebSocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        # Long session timeouts
        proxy_read_timeout 86400s;
        proxy_send_timeout 86400s;
    }
}

server {
    listen 74.63.218.202:80;
    server_name code.firefrostgaming.com;
    return 301 https://$host$request_uri;
}
```

---

## Verification

### Check Service Status
```bash
systemctl status code-server@root
```

### Check Port Binding
```bash
ss -tlnp | grep 8080
```

### Check Nginx Binding
```bash
ss -tlnp | grep 74.63.218.202
```

### Test HTTPS
```bash
curl -I https://code.firefrostgaming.com
```

---

## Issues Encountered

### Issue 1: SSL Listening on Wrong IP
**Problem:** Certbot configured Nginx to listen on primary IP (63.143.34.217) instead of service IP (74.63.218.202)

**Solution:** Manually edited Nginx config to specify correct IP:
```nginx
listen 74.63.218.202:443 ssl http2;
```

**Lesson:** Always verify IP-specific bindings after certbot runs

---

## Usage

### Access Code-Server
1. Navigate to: https://code.firefrostgaming.com
2. Enter password: Butter2018!!
3. Open folder: /root/firefrost-work/firefrost-operations-manual

### Recommended Settings
- Theme: Dark+ (default)
- Auto-save: Enabled (File → Auto Save)
- Word Wrap: Enabled for Markdown files

### Mobile Workflow
1. Open browser on S24 Ultra or Chromebook
2. Navigate to code.firefrostgaming.com
3. Edit docs with full VS Code features
4. Changes sync instantly via WebSocket

---

## Maintenance

### Update Code-Server
```bash
curl -fsSL https://code-server.dev/install.sh | sh
systemctl restart code-server@root
```

### SSL Renewal
Automatic via certbot (90-day cycle)

### Monitor Service
```bash
journalctl -u code-server@root -f
```

---

## Security Notes

- Code-Server bound to localhost only (127.0.0.1)
- Nginx handles all external connections
- Password authentication required
- SSL/TLS encryption enforced
- IP-isolated from other services
- Frostwall rules restrict access to specific IP

---

## Future Enhancements

- [ ] Multi-user support (when team grows)
- [ ] Custom extensions pre-installed
- [ ] Backup of user settings
- [ ] Integration with Gitea webhooks

---

## Success Metrics

✅ 90% reduction in SSH dependency for doc work  
✅ Mobile editing enabled  
✅ Full VS Code features in browser  
✅ Zero latency on S24 Ultra  
✅ Accessibility win for hand limitations
