func ConvertImageRegistryOverrideStringToMap ¶

func ConvertImageRegistryOverrideStringToMap(envVar string) map[string][]string

ConvertImageRegistryOverrideStringToMap translates the environment variable containing registry source to mirror mappings back to a map[string]string structure that can be ingested by the registry image content policies release provider

func ConvertOpenShiftImageRegistryOverridesToCommandLineFlag ¶

func ConvertOpenShiftImageRegistryOverridesToCommandLineFlag(registryOverrides map[string][]string) string

ConvertOpenShiftImageRegistryOverridesToCommandLineFlag converts a map of image registry sources and their mirrors into a string

func ConvertRegistryOverridesToCommandLineFlag ¶

func ConvertRegistryOverridesToCommandLineFlag(registryOverrides map[string]string) string

ConvertRegistryOverridesToCommandLineFlag converts a map of registry sources and their mirrors into a string

func GetControlPlaneOperatorImage ¶

func GetControlPlaneOperatorImage(ctx context.Context, hc *hyperv1.HostedCluster, releaseProvider releaseinfo.Provider, hypershiftOperatorImage string, pullSecret []byte) (string, error)

GetControlPlaneOperatorImage resolves the appropriate control plane operator image based on the following order of precedence (from most to least preferred):

1. The image specified by the ControlPlaneOperatorImageAnnotation on the HostedCluster resource itself
2. The hypershift image specified in the release payload indicated by the HostedCluster's release field
3. The hypershift-operator's own image for release versions 4.9 and 4.10
4. The registry.ci.openshift.org/hypershift/hypershift:4.8 image for release version 4.8

If no image can be found according to these rules, an error is returned.

func GetControlPlaneOperatorImageLabels ¶

func GetControlPlaneOperatorImageLabels(ctx context.Context, hc *hyperv1.HostedCluster, controlPlaneOperatorImage string, pullSecret []byte, imageMetadataProvider ImageMetadataProvider) (map[string]string, error)

GetControlPlaneOperatorImageLabels resolves the appropriate control plane operator image labels based on the following order of precedence (from most to least preferred):

1. The labels specified by the ControlPlaneOperatorImageLabelsAnnotation on the HostedCluster resource itself
2. The image labels in the medata of the image as resolved by GetControlPlaneOperatorImage

func GetPayloadImage ¶

func GetPayloadImage(ctx context.Context, releaseImageProvider releaseinfo.Provider, hc *hyperv1.HostedCluster, component string, pullSecret []byte) (string, error)

func GetPayloadImageFromRelease ¶

func GetPayloadImageFromRelease(ctx context.Context, releaseImageProvider releaseinfo.Provider, release string, component string, pullSecret []byte) (string, error)

func GetPayloadVersion ¶

func GetPayloadVersion(ctx context.Context, releaseImageProvider releaseinfo.Provider, hc *hyperv1.HostedCluster, pullSecret []byte) (*semver.Version, error)

func GetRegistryOverrides ¶

func GetRegistryOverrides(ctx context.Context, ref reference.DockerImageReference, source, mirror string) (*reference.DockerImageReference, bool, error)

func GetRepoSetup ¶

func GetRepoSetup(ctx context.Context, imageRef string, pullSecret []byte) (distribution.Repository, *reference.DockerImageReference, error)

GetRepoSetup connects to a repo and pulls the imageRef's docker image information from the repo. Returns the repo and the docker image.

func HCControlPlaneReleaseImage ¶

func HCControlPlaneReleaseImage(hcluster *hyperv1.HostedCluster) string

func HCPControlPlaneReleaseImage ¶

func HCPControlPlaneReleaseImage(hcp *hyperv1.HostedControlPlane) string

func ImageLabels ¶

func ImageLabels(metadata *dockerv1client.DockerImageConfig) map[string]string

ImageLabels returns labels on a given image metadata. Labels may be recorded on either Config or ContainerConfig depending on how the image was built, so fall back to ContainerConfig when Config carries no labels. Returning Config.Labels unconditionally (even when nil) would silently drop labels that live on ContainerConfig, which can turn a present capability label into a spurious "absent" and, for the AWS default worker security group capability, flip an AWSMachineTemplate hash and roll all workers (OCPBUGS-105464).

func LookupMappedImage ¶

func LookupMappedImage(ctx context.Context, ocpOverrides map[string][]string, image string, pullSecretBytes []byte, getMetadataFn GetMetadataFn) (string, error)

LookupMappedImage looks up a mapped image based on OCP overrides by allowing tests to control the image availability check without reaching out to actual registries
