Types ¶
type BlobPruneFunc ¶
func DeletingBlobPruneFunc ¶
func DeletingBlobPruneFunc(registryClient *http.Client) BlobPruneFunc
type ImagePruneFunc ¶
ImagePruneFunc is a function that is invoked for each image that is prunable.
func DeletingImagePruneFunc ¶
func DeletingImagePruneFunc(images client.ImageInterface) ImagePruneFunc
DeletingImagePruneFunc returns an ImagePruneFunc that deletes the image.
type ImagePruner ¶
type ImagePruner interface {
// Run prunes images and layers.
Run(pruneImage ImagePruneFunc, pruneStream ImageStreamPruneFunc, pruneLayer LayerPruneFunc, pruneBlob BlobPruneFunc, pruneManifest ManifestPruneFunc)
}
ImagePruner knows how to prune images and layers.
func NewImagePruner ¶
func NewImagePruner(keepYoungerThan time.Duration, tagRevisionsToKeep int, images *imageapi.ImageList, streams *imageapi.ImageStreamList, pods *kapi.PodList, rcs *kapi.ReplicationControllerList, bcs *buildapi.BuildConfigList, builds *buildapi.BuildList, dcs *deployapi.DeploymentConfigList) ImagePruner
NewImagePruner creates a new ImagePruner.
Images younger than keepYoungerThan and images referenced by image streams and/or pods younger than keepYoungerThan are preserved. All other images are candidates for pruning. For example, if keepYoungerThan is 60m, and an ImageStream is only 59 minutes old, none of the images it references are eligible for pruning.
tagRevisionsToKeep is the number of revisions per tag in an image stream's status.tags that are preserved and ineligible for pruning. Any revision older than tagRevisionsToKeep is eligible for pruning.
images, streams, pods, rcs, bcs, builds, and dcs are the resources used to run the pruning algorithm. These should be the full list for each type from the cluster; otherwise, the pruning algorithm might result in incorrect calculations and premature pruning.
The ImagePruner performs the following logic: remove any image contaning the annotation openshift.io/image.managed=true that was created at least *n* minutes ago and is *not* currently referenced by:
- any pod created less than *n* minutes ago - any image stream created less than *n* minutes ago - any running pods - any pending pods - any replication controllers - any deployment configs - any build configs - any builds - the n most recent tag revisions in an image stream's status.tags
When removing an image, remove all references to the image from all ImageStreams having a reference to the image in `status.tags`.
Also automatically remove any image layer that is no longer referenced by any images.
type ImageStreamPruneFunc ¶
type ImageStreamPruneFunc func(stream *imageapi.ImageStream, image *imageapi.Image) (*imageapi.ImageStream, error)
func DeletingImageStreamPruneFunc ¶
func DeletingImageStreamPruneFunc(streams client.ImageStreamsNamespacer) ImageStreamPruneFunc
type LayerPruneFunc ¶
func DeletingLayerPruneFunc ¶
func DeletingLayerPruneFunc(registryClient *http.Client) LayerPruneFunc
DeletingLayerPruneFunc returns a LayerPruneFunc that uses registryClient to send a layer deletion request to the regsitry.
The request URL is http://registryURL/admin/<repo>/layers/<digest> and it is a DELETE request.
type ManifestPruneFunc ¶
func DeletingManifestPruneFunc ¶
func DeletingManifestPruneFunc(registryClient *http.Client) ManifestPruneFunc
