SSL & Reverse Proxy

Use NGINX to serve Aicser over HTTPS on port 443.

Get an SSL certificate​

Use Certbot with Let's Encrypt:

sudo apt install certbot

# Stop any service on port 80 first, then:
sudo certbot certonly --standalone -d your-domain.com

Certificates are stored at /etc/letsencrypt/live/your-domain.com/.

NGINX configuration​

Create /etc/nginx/sites-available/aicser:

server {
    listen 80;
    server_name your-domain.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name your-domain.com;

    ssl_certificate     /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;

    # Next.js client
    location / {
        proxy_pass http://localhost:3001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

    # FastAPI server
    location /api/ {
        proxy_pass http://localhost:8001;
        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 reload:

sudo ln -s /etc/nginx/sites-available/aicser /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx

Update environment​

After setting up SSL, update NEXT_PUBLIC_API_URL in deploy/.env:

NEXT_PUBLIC_API_URL=https://your-domain.com/api

Rebuild the client:

cd deploy && make ee-recreate

Automatic certificate renewal​

Let's Encrypt certificates expire every 90 days. Test automatic renewal:

sudo certbot renew --dry-run
