Cleaning Things Up

To delete individual containers use the command docker container rm [ID-OF-CONTAINER].

To list only the IDs for all containers use the command docker container ls -aq. The -aq flag specifies that all container IDs should be listed.

To delete all containers run the command docker container rm $(docker container ls -aq). Note that this is the bash command. If you are using a different shell your command may be slightly different.

Run docker container ls -a to verify that all containers are deleted.

Similarly you can list images using docker image ls and delete individual images using the command docker image rm [NAME-OF-IMAGE].

Docker prevents you from deleting images and containers that are still in use.
