OPENSHIFT CLI ADM PRUNE(1)

NAME

openshift cli adm prune images - Remove unreferenced images

SYNOPSIS

openshift cli adm prune images [OPTIONS]

DESCRIPTION

Remove image stream tags, images, and image layers by age or usage

This command removes historical image stream tags, unused images, and unreferenced image layers from the integrated registry. It prefers images that have been directly pushed to the registry, but you may specify --all to include images that were imported (if registry mirroring is enabled).

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.

OPTIONS

--all=false
    Include images that were not pushed to the registry but have been mirrored by pullthrough. Requires --registry-url

--certificate-authority=""
    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.

--confirm=false
    If true, specify that image pruning should proceed. Defaults to false, displaying what would be deleted but not actually deleting anything.

--keep-tag-revisions=3
    Specify the number of image revisions for a tag in an image stream that will be preserved.

--keep-younger-than=0
    Specify the minimum age of an image for it to be considered a candidate for pruning.

--prune-over-size-limit=false
    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.

--registry-url=""
    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.

OPTIONS INHERITED FROM PARENT COMMANDS

--api-version=""
    DEPRECATED: The API version to use when talking to the server

--as=""

--log-flush-frequency=0
    Maximum number of seconds between log flushes

--match-server-version=false
    Require server version to match client version

-n, --namespace=""
    If present, the namespace scope for this CLI request

--request-timeout="0"
    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.

--token=""
    Bearer token for authentication to the API server

--user=""

EXAMPLE

      # See, what the prune command would delete if only images more than an hour old and obsoleted
      # by 3 newer revisions under the same tag were considered.
      openshift cli adm prune images --keep-tag-revisions=3 --keep-younger-than=60m

      # To actually perform the prune operation, the confirm flag must be appended
      openshift cli adm prune images --keep-tag-revisions=3 --keep-younger-than=60m --confirm

      # See, what the prune command would delete if we're interested in removing images
      # exceeding currently set limit ranges ('openshift.io/Image')
      openshift cli adm prune images --prune-over-size-limit

      # To actually perform the prune operation, the confirm flag must be appended
      openshift cli adm prune images --prune-over-size-limit --confirm
