    Remove Docker Images

    To remove an images, Docker provides rmi option. Using this we can delete any docker images from our local system. For example use below command with changing IMAGE ID with your Docker image id.

    # docker rmi  <IMAGE ID>

    or you can simply remove images using repository name (image name)

    # docker rmi ubuntu

    In case you have two images with same name, add tag name while deletion

    # docker rmi  ubuntu:latest
    Share.
