💡 Hint

Common Mistakes

Using 'pull' instead of 'rm' will try to download an image.

Using 'run' tries to start a container, not remove an image.

The docker image rm command removes an image by its ID or name.

medium

Complete the command to force remove a Docker image even if it is used by stopped containers.

Docker

docker image rm [1] IMAGE_ID

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

A--force

B--quiet

C--all

D--no-cache

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--all' removes all images, not just one.

Using '--quiet' only suppresses output, does not force removal.

The --force option forces removal of the image even if it is used by stopped containers.

hard

Fix the error in the command to remove all dangling images.

Docker

docker image rm $(docker images -f [1] -q)

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

Aall=true

Bdangling=false

Clabel=unused

Ddangling=true

Attempts:

💡 Hint

Common Mistakes

Using 'dangling=false' selects images that are in use.

Using 'all=true' is not a valid filter.

The filter dangling=true selects images not tagged and unused, which can be removed safely.

4fill in blank

hard

Fill both blanks to remove all images that are not used by any container.

Docker

docker image prune [1] [2]

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

A-a

B--force

C--all

D--quiet

Attempts:

3 left

💡 Hint

Common Mistakes

Using only one option may not remove all images or may ask for confirmation.

Using '--quiet' only suppresses output, does not remove images.

The -a or --all option removes all unused images, and --force skips confirmation prompts.

5fill in blank

hard

Fill both blanks to remove images by name, force removal.

Docker

docker image rm [1] [2] IMAGE_NAME

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

A--force

B--quiet

C-f

D-q

Attempts:

3 left

💡 Hint

Common Mistakes

Using both '-f' and '--force' is redundant but allowed; here the order matters.

Using '--quiet' or '-q' will cause an error as they are invalid flags.

-f and --force both force removal; using both is redundant but allowed. The command removes the image named IMAGE_NAME forcefully.
