What is the purpose of the docker rm command?

The primary function of the docker rm command is to remove one or more stopped containers. When a container is no longer needed, perhaps after its task has been completed, it can be removed to free up system resources and maintain a clutter-free environment.

Using this command helps manage the lifecycle of containers, allowing you to clean up those that are not actively running. It's important to note that this command only affects stopped containers; it will not remove containers that are currently running.

This functionality is essential for effective container management, especially in development and production environments where numerous containers may be created and destroyed frequently.
