docker image rm fce289e99eb9 equals docker rmi fce289e99eb9

docker run skinglzw/hello-world executes 5 times to create container

docker ps -a

docker container ls -aq enumerates all containerId similar to docker container ls -a| awk {'print$1'}

docker rm $(docker container ls -aq) Delete all containers

docker

There are 5 identical image containers deleted in batches

docker container ls -f "status=exited" List the status is exited
