Functions

func AssertDeletedStorageFiles added in v3.6.1 

func AssertDeletedStorageFiles(deleted, expected *RegistryStorageFiles) error

AssertDeletedStorageFiles compares lists of deleted files against expected. An error will be generated for each entry present in just one of these sets.

func BuildAndPushChildImage added in v3.6.1 

func BuildAndPushChildImage(
	oc *exutil.CLI,
	dClient *dockerclient.Client,
	parent string,
	name, tag string,
	numberOfNewLayers int,
	outSink io.Writer,
	removeBuiltImage bool,
) (string, string, error)

BuildAndPushChildImage tries to build and push an image of given name and number of layers. It instructs Docker daemon directly. Built image is stored as an image stream tag <name>:<tag>. Returned is an image digest, its ID (docker daemon's internal representation) and an error if any.

func BuildAndPushImageOfSizeWithBuilder 

func BuildAndPushImageOfSizeWithBuilder(
	oc *exutil.CLI,
	dClient *dockerclient.Client,
	namespace, name, tag string,
	size uint64,
	numberOfLayers int,
	shouldSucceed bool,
) error

BuildAndPushImageOfSizeWithBuilder tries to build an image of wanted size and number of layers. Built image is stored as an image stream tag <name>:<tag>. If shouldSucceed is false, a build is expected to fail with a denied error. Note the size is only approximate. Resulting image size will be different depending on used compression algorithm and metadata overhead.

func BuildAndPushImageOfSizeWithDocker 

func BuildAndPushImageOfSizeWithDocker(
	oc *exutil.CLI,
	dClient *dockerclient.Client,
	name, tag string,
	size uint64,
	numberOfLayers int,
	outSink io.Writer,
	shouldSucceed bool,
	removeBuiltImage bool,
) (string, string, error)

BuildAndPushImageOfSizeWithDocker tries to build an image of wanted size and number of layers. It instructs Docker daemon directly. Built image is stored as an image stream tag <name>:<tag>. If shouldSucceed is false, a push is expected to fail with a denied error. Note the size is only approximate. Resulting image size will be different depending on used compression algorithm and metadata overhead. Returned is an image digest, its ID (docker daemon's internal representation) and an error if any.

func ConfigureRegistry added in v3.8.0 

func ConfigureRegistry(oc *exutil.CLI, desiredState RegistryConfiguration) error

ConfigureRegistry re-deploys the registry pod if its configuration doesn't match the desiredState. The function blocks until the registry is ready.

func DoesRegistryAcceptSchema2 added in v3.8.0 

func DoesRegistryAcceptSchema2(oc *exutil.CLI) (bool, error)

DoesRegistryAcceptSchema2 returns true if the integrated registry is configured to accept manifest V2 schema 2.

func EnsureRegistryAcceptsSchema2 added in v3.8.0 

func EnsureRegistryAcceptsSchema2(oc *exutil.CLI, accept bool) error

EnsureRegistryAcceptsSchema2 checks whether the registry is configured to accept manifests V2 schema 2 or not. If the result doesn't match given accept argument, registry's deployment config will be updated accordingly and the function will block until the registry have been re-deployed and ready for new requests.

func GetDockerRegistryURL 

func GetDockerRegistryURL(oc *exutil.CLI) (string, error)

GetDockerRegistryURL returns a cluster URL of internal docker registry if available.

func GetImageLabels 

func GetImageLabels(c imagetypedclientset.ImageStreamImageInterface, imageRepoName, imageRef string) (map[string]string, error)

GetImageLabels retrieves Docker labels from image from image repository name and image reference

func GetRegistryPod added in v3.8.0 

func GetRegistryPod(podsGetter kcoreclient.PodsGetter) (*kapiv1.Pod, error)

GetRegistryPod returns the youngest registry pod deployed.

func GetRegistryStorageSize added in v3.8.0 

func GetRegistryStorageSize(oc *exutil.CLI) (int64, error)

GetRegistryStorageSize returns a number of bytes occupied by registry's data on its filesystem.

func IsBlobStoredInRegistry 

func IsBlobStoredInRegistry(
	oc *exutil.CLI,
	dgst godigest.Digest,
	repository string,
) (bool, bool, error)

IsBlobStoredInRegistry verifies a presence of the given blob on registry's storage. The registry must be deployed with a filesystem storage driver. If repository is given, the presence will be verified also for layer link inside the ${repository}/_layers directory. First returned bool says whether the blob is present globally in the registry's storage. The second says whether the blob is linked in the given repository.

func IsEmptyDigest 

func IsEmptyDigest(dgst godigest.Digest) bool

IsEmptyDigest returns true if the given digest matches one of empty blobs.

func LogRegistryPod added in v3.8.0 

func LogRegistryPod(oc *exutil.CLI) error

LogRegistryPod attempts to write registry log to a file in artifacts directory.

func MirrorBlobInRegistry 

func MirrorBlobInRegistry(oc *exutil.CLI, dgst godigest.Digest, repository string, timeout time.Duration) error

MirrorBlobInRegistry forces a blob of external image to be mirrored in the registry. The function expects the blob not to exist before a GET request is issued. The function blocks until the blob is mirrored or the given timeout passes.

Types

type CleanUpContainer added in v3.6.1 

type CleanUpContainer struct {
	OC *exutil.CLI
	// contains filtered or unexported fields
}
