We are going to use Docker's rmi command.
Docker rmi command removes (and un-tags) one or more images from the host. If an image has multiple tags, using this command with the tag as a parameter only removes the tag. If the tag is the only one for the image, both the image and the tag are removed.
$ docker rmi $(docker images <your_docker_image_name>)
Example:
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox 1.32.0 dc3bacd8b5ea 16 hours ago 1.23MB
$ docker rmi busybox
untagged: busybox:1.32.0
Multiple Tags
If you have different tags for same image name;
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
busybox 1.32.0 dc3bacd8b5ea 16 hours ago 1.23MB
busybox latest dc3bacd8b5ea 16 hours ago 1.23MB
busybox 1.31 1c35c4412082 5 months ago 1.22MB
You should use it with -q flag:
$ docker rmi $(docker images -q <your_docker_image_name>)
The -q flag returns only the matching images IDs which can be fed to docker rmi.
Error
If you encounter an error like below you have to use it with -f (force) flag:
Error response from daemon: conflict: unable to delete dc3bacd8b5ea (must be forced) - image is referenced in multiple repositories
$ docker rmi -f $(docker images -q <your_docker_image_name>)
All done!
