If you have a lot of them, it can be really tedious to remove them, but lucky for us Docker has a few commands to help us eliminate dangling images. In older versions of Docker (and this still works today), you can delete dangling images on their own by running docker rmi -f $(docker images -f "dangling=true" -q) .
