In this article, we will discuss how to remove the docker images which are either active, not active, untagged, tagged with child images and etc.
The below command will delete the images which are in either in-active state or un-tagged state but can not delete the images which are inactive and tagged with child images
docker image prune
The below command will delete all images irrespective of the image status. It means that, clean up all images. So while performing the below command be careful. It will ask confirmation like Are you sure you want to continue? [Y/N]
So if you can confirm by pressing Y, then all images will be deleted.
docker image prune -a
We can skip the confirmation by adding the option -f
docker image prune -a -f
Output
WARNING! This will remove all images without at least one container associated to them. Are you sure you want to continue?
