openshift cli adm prune images — Remove unreferenced images
openshift cli adm prune images [Options]
Prune images no longer needed due to age and/or status
By default, the prune operation performs a dry run making no changes to internal registry. A --confirm flag is needed for changes to be effective.
Only a user with a cluster role system:image-pruner or higher who is logged-in will be able to actually delete the images.
The path to a certificate authority bundle to use when communicating with the managed Docker registries. Defaults to the certificate authority data from the current user's config file.
Specify that image pruning should proceed. Defaults to false, displaying what would be deleted but not actually deleting anything.
Specify the number of image revisions for a tag in an image stream that will be preserved.
Specify the minimum age of an image for it to be considered a candidate for pruning.
Specify if images which are exceeding LimitRanges (see 'openshift.io/Image'), specified in the same namespace, should be considered for pruning. This flag cannot be combined with --keep-younger-than nor --keep-tag-revisions.
The address to use when contacting the registry, instead of using the default value. This is useful if you can't resolve or reach the registry (e.g.; the default is a cluster-internal URL) but you do have an alternative route that works.

If present, the namespace scope for this CLI request
The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.
