Why some containers expose the port 22?

Sometimes, you need to debug inside a container that was launched using docker-compose command line instead of Visual Studio.

The whole process is described in detail in the following post.

Obviously, you can remove this port from the docker-compose configuration, or expose remote shell using a different port.
