Run Docker Container In Detached Mode

Why We Use Port Mapping?

The network services of a container are made accessible to the host or external network through port mapping in Docker. Docker containers can only communicate with other containers on the same Docker network and run by default in isolation from the host and external networks.

The port is not actually published by the EXPOSE command.
