docker-image-rm: Remove one or more images
docker-image-rm - Remove one or more images
docker image rm [OPTIONS] IMAGE [IMAGE...]
Removes (and un-tags) one or more images from the host node. 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.
This does not remove images from a registry. You cannot remove an image of a running container unless you use the -f option. To see all images on a host use the docker image ls command.
Removing an image
Here is an example of removing an image:
docker image rm fedora/httpd
