Overview

Package image implements evaluators of usage for imagestreams and images. They are supposed to be passed to resource quota controller and origin resource quota admission plugin.

Functions

func NewImageQuotaRegistry

func NewImageQuotaRegistry(isInformer imageinternalversion.ImageStreamInformer, imageClient imageclient.ImageStreamTagsGetter) quota.Registry

NewImageQuotaRegistry returns a registry for quota evaluation of OpenShift resources related to images in internal registry. It evaluates only image streams and related virtual resources that can cause a creation of new image stream objects.

func NewImageQuotaRegistryForAdmission

func NewImageQuotaRegistryForAdmission(isInformer imageinternalversion.ImageStreamInformer, imageClient imageclient.ImageStreamTagsGetter) quota.Registry

NewImageQuotaRegistryForAdmission returns a registry for quota evaluation of OpenShift resources related to images in internal registry. It evaluates only image streams and related virtual resources that can cause a creation of new image stream objects. This is different that is used for reconciliation because admission has to check all forms of a resource (legacy and groupified), but reconciliation only has to check one.

func NewImageStreamEvaluator

func NewImageStreamEvaluator(store imageinternalversion.ImageStreamLister) kquota.Evaluator

NewImageStreamEvaluator computes resource usage of ImageStreams. Instantiating this is necessary for resource quota admission controller to properly work on image stream related objects.

func NewImageStreamImportEvaluator

func NewImageStreamImportEvaluator(store imageinternalversion.ImageStreamLister) kquota.Evaluator

NewImageStreamImportEvaluator computes resource usage for ImageStreamImport objects. This particular kind is a virtual resource. It depends on ImageStream usage evaluator to compute image numbers before the the admission can work.

func NewImageStreamTagEvaluator

func NewImageStreamTagEvaluator(store imageinternalversion.ImageStreamLister, istGetter imageclient.ImageStreamTagsGetter) kquota.Evaluator

NewImageStreamTagEvaluator computes resource usage of ImageStreamsTags. Its sole purpose is to handle UPDATE admission operations on imageStreamTags resource.
