💡 Hint

Common Mistakes

Using 'start' instead of 'rm' will try to start the container, not remove it.

Using 'run' or 'create' will create or start containers, not remove them.

The docker container rm command removes a container. Here, it removes the container named my_container.

Using '--stop' is not a valid option for removal.

Using '-d' is for detached mode, not removal.

Fix the error in the command to remove all stopped containers.

Docker

docker container rm $(docker ps -a -q [1])

Drag options to blanks, or click blank then click option'

A--filter status=created

B--filter status=running

C--filter status=exited

D--filter status=paused

💡 Hint

Common Mistakes

Using 'running' will try to remove running containers, which may fail.

Using 'paused' or 'created' will not list stopped containers.

The docker ps -a -q --filter status=exited lists all stopped containers. Removing these removes only stopped containers.

Fill both blanks to remove all running containers.

Docker

docker container rm [1] $(docker ps -a -q [2])

Drag options to blanks, or click blank then click option'

A-f

B--filter status=exited

C--filter status=running

D-a

Attempts:

💡 Hint

Common Mistakes

Not using -f will cause errors when removing running containers.

Filtering by exited will not select running containers.

The -f forces removal of running containers, and filtering by status=running selects running containers to remove.

Fill all three blanks to remove containers with names starting with 'web' that are stopped.

Docker

docker container rm $(docker ps -a -q [1] [2]=[3])

Drag options to blanks, or click blank then click option'

A--filter

Bname

Cweb

Dstatus

💡 Hint

Common Mistakes

Using 'status' instead of 'name' will filter by container state, not name.

Not using '--filter' will cause syntax errors.

Use --filter name=web to select containers with names starting with 'web'. Combined with docker ps -a -q, this lists matching containers to remove.
