OPENSHIFT ADMIN PRUNE(1)

NAME

openshift admin prune images - Remove unreferenced images

SYNOPSIS

openshift admin prune images [OPTIONS]

DESCRIPTION

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.

OPTIONS

--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
    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=""
    Username to impersonate for the operation.

--client-certificate=""
    Path to a client certificate file for TLS.

--client-key=""
    Path to a client key file for TLS.

--cluster=""
    The name of the kubeconfig cluster to use

--config=""
    Path to the config file to use for CLI requests.

--context=""
    The name of the kubeconfig context to use

--google-json-key=""
    The Google Cloud Platform Service Account JSON Key to use for authentication.

--insecure-skip-tls-verify=false
    If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.

--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.

--server=""
    The address and port of the Kubernetes API server

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

--user=""
    The name of the kubeconfig user to use

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 admin prune images --keep-tag-revisions=3 --keep-younger-than=60m
      # To actually perform the prune operation, the confirm flag must be appended
      openshift admin 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 LimitRanges ('openshift.io/Image')
      openshift admin prune images --prune-over-size-limit
      # To actually perform the prune operation, the confirm flag must be appended
      openshift admin prune images --prune-over-size-limit --confirm
