This project explores how to dockerize a next 14 app.

Go to directory /etc/nginx/sites-enabled and create a file named <your-domain.com>

for example /etc/nginx/sites-enabled/next-docker.donis3.com

# Define upstream server (your Docker container)

# Main server block
server {
    listen 80;

    # App Url
    server_name next-docker.donis3.com;

    # Location block for handling requests
    location / {
        proxy_pass http://localhost:3000; # Proxy requests to upstream server
        proxy_http_version 1.1;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

After this initial setup , run nginx -t to verify config is correct.

We may now continue with certbot installation

Following commands will install certbot and configure ssl for all sites at /etc/nginx/sites-enabled/

sudo snap install --classic certbot

sudo ln -s /snap/bin/certbot /usr/bin/certbot

sudo certbot --nginx

sudo certbot renew --dry-run
