Removing containers

In order to delete a container, you can use the docker rm command. If the container you want to delete is running, you can stop and delete it or use the -f option and it will do the job:

$ docker rm 3b1150b50343
Error response from daemon: You cannot remove a running container 3b1150b5034329cd9e70f90ee21531b8b1ab1d4a85141fd3a362cd40db80e193. Stop the container before attempting removal or force remove

Let's try using -f option.

$ docker rm  -f 3b1150b50343

Another trick you can use to delete all containers, both stopped and running, is the following command:

$ docker rm -f $(docker ps -qa)
830a42f2e727
00f343906df3
5e3820a43ffc
419e7ce2567e

Verify that all the containers are deleted:

$ docker ps  -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
