Cannot kill container: foo: Container foo is not running

Perhaps kill is incorrect terminology, or I'm at least using it incorrectly.

How do I destroy docker containers? Put them in the trash. Delete. Remove. Erase.

docker container kill $(docker ps -a -q | awk '{print $1}')

doesn't quite work:

Error response from daemon: Cannot kill container: 06e44d24ba8d: Container 06e44d24ba8d3df83e10a1829f04755cb9053faa68ab3dabccd10c3ee1c80322 is not running

docker kill will not destroy containers, it will just kill (stop) the running containers. But docker ps -a will show also the non-running containers, so you get an error for all these non-running containers.

Leave out the -a to kill only all running containers:

docker kill $(docker ps -q)

Use docker stop instead of docker kill if you want the processes to first try to terminate themselves (SIGTERM) instead of killing directly (SIGKILL).

Or use docker rm to remove (destroy) containers:

docker rm --force $(docker ps -a -q)

--force or -f is needed to also rm running containers.

Note:
this will remove all containers.

Use docker container prune to remove all stopped containers.

Please read the docs or run docker help to get more information about all the commands.
