Docker also has some commands that allow your system to work with images. The most commonly used commands are the following:

• Listing all the images available on the host:

⋊> ~ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx latest ae513a47849c 4 weeks ago 109MB

• Removing images:

⋊> ~ docker rmi nginx
Untagged: nginx:latest
Untagged: nginx@sha256:0fb320e2a1b1620b4905facb3447e3d84ad36da0b2c8aa8fe3a5a81d1187b884
