Explanation

docker rm permanently removes containers and their writable layers. By default, it only removes stopped containers. The -f flag first sends a SIGKILL to stop them. This command helps keep Docker environments clean.

Common Use Cases

  • Clean up stopped containers
  • Force remove crashed or stuck containers

Best Practices

  • Use --rm in docker run to auto-remove short-lived containers
  • Run docker ps -a before deletion

Common Mistakes to Avoid

  • Removing containers that hold important data without volumes

Troubleshooting

Problem: Cannot remove running container

Solution: Add -f flag to force removal.

Examples

Remove stopped container

docker rm my_container

Force remove running container

docker rm -f my_container
