The command 'docker run --rm' is used to automatically remove the container once it has stopped running. This is particularly useful for temporary containers that are not intended to persist beyond their execution. When the --rm flag is specified, Docker performs a cleanup operation, ensuring that the container’s resources are freed and that it does not clutter your environment with stopped containers.

This functionality is beneficial in scenarios where you run short-lived tasks, such as testing or one-off commands, as it eliminates the need for manual cleanup after the container's work is done. The automatic removal feature helps maintain a clean working directory, making it easier to manage containers without manually deleting them after they are no longer in use.

While the other options present various aspects of Docker functionality, they do not accurately describe the purpose of the '--rm' flag in the context of container management.
