So far, we have discussed a few practical examples to clearly articulate the nitty-gritty of Docker containers. In this section, we'll introduce a few basic as well as a few advanced command structures for meticulously illustrating how the Docker containers can be managed.
The Docker Engine enables you to start, stop, and restart a container with a set of docker subcommands. Let's begin with the docker stop subcommand, which stops a running container.
