In the new version of Docker, commands are updated, and some management commands are added:

docker container ls

It is used to list all the running containers.

docker container ls -a

And then, if you want to clean them all,

docker rm $(docker ps -aq)

It is used to list all the containers created irrespective of its state.

And to stop all the Docker containers (force)

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