CMD ["node", "server.js"]

If your project needs to listen to a specific port or hostname, you can define PORT or HOSTNAME environment variables before running server.js. For example, run PORT=8080 HOSTNAME=0.0.0.0 node server.js to start the server on http://0.0.0.0:8080

DOMAIN (DNS Resolution) -> SERVER_IP/ -> localhost:3000(reverse proxy)

proxy_set_header Host $host;

And I don't think Logs can happen.
