Functions ¶
func ExtractUniqueOCIRefs ¶
ExtractUniqueOCIRefs extracts and deduplicates the container images of the standard workloads in the given manifests. Images of custom resources are ignored, even when the resource embeds a pod spec.
func SplitOCIRef ¶
SplitOCIRef breaks an OCI reference into registry, repository, and tag/digest.
Types ¶
type ImageMirror ¶
type ImageMirror struct {
// contains filtered or unexported fields
}
ImageMirror handles image replacement and OCI artifact replication for configured registry mirrors.
func NewImageMirror ¶
func NewImageMirror(ctx context.Context, k8sClient client.Client, config *RegistryMirrorConfig, namespace string) (*ImageMirror, error)
NewImageMirror creates an ImageMirror with credentials from the configured Secret.
func NewImageMirrorForTest ¶
func NewImageMirrorForTest(config *RegistryMirrorConfig, auth authn.Authenticator, fetcher func(ref string, opts ...crane.Option) ([]byte, error)) *ImageMirror
NewImageMirrorForTest creates an ImageMirror for testing with explicit auth and manifest fetcher.
func (*ImageMirror) BuildImageTransformations ¶
func (m *ImageMirror) BuildImageTransformations(manifestSets ...string) []ImageTransform
BuildImageTransformations extracts image refs from the given rendered manifest sets and returns the upstream-to-mirror rewrites for them, skipping refs that already point at a mirror and deduplicating across sets.
func (*ImageMirror) EnsureChartReplicated ¶
func (m *ImageMirror) EnsureChartReplicated(ctx context.Context, ociRef string) (replicatedRef string, manifest []byte, err error)
EnsureChartReplicated warms the pull-through cache for a chart on a mirror domain.
func (*ImageMirror) EnsureImageReplicated ¶
func (m *ImageMirror) EnsureImageReplicated(ctx context.Context, ociRef string) (replicatedRef string, manifest []byte, err error)
EnsureImageReplicated warms the pull-through cache for a container image, including upstream refs.
func (*ImageMirror) ReplicateOCIArtifacts ¶
func (m *ImageMirror) ReplicateOCIArtifacts(ctx context.Context, alreadyReplicated []string, manifestSets ...string) ([]string, error)
ReplicateOCIArtifacts triggers replication for OCI artifacts found in the given manifest sets, skipping already-replicated refs and deduplicating across sets.
type ImageTransform ¶
ImageTransform represents an upstream-to-mirror image reference rewrite.
type RegistryMirror ¶
type RegistryMirror struct {
BaseDomain string `yaml:"baseDomain"`
SubPath string `yaml:"subPath"`
}
RegistryMirror represents a single registry mirror configuration.
type RegistryMirrorConfig ¶
type RegistryMirrorConfig struct {
PrimaryMirror string `yaml:"primaryMirror"`
RegistryMirrors map[string]RegistryMirror `yaml:"registryMirrors"`
SecretName string `yaml:"secretName,omitempty"`
}
RegistryMirrorConfig represents the registry mirror configuration structure.
func GetRegistryMirrorConfig ¶
func GetRegistryMirrorConfig(ctx context.Context, k8sClient client.Reader, orgName string) (*RegistryMirrorConfig, error)
GetRegistryMirrorConfig retrieves and parses the registry mirror configuration from the Organization's ConfigMap. Registry mirrors redirect image pulls from original registries to mirror registries.
func (*RegistryMirrorConfig) ResolveOCIRef ¶
func (c *RegistryMirrorConfig) ResolveOCIRef(imageRef string) *ResolvedOCIRef
ResolveOCIRef looks up the mirror configuration for an OCI reference.
type ResolvedOCIRef ¶
type ResolvedOCIRef struct {
Registry string
Mirror RegistryMirror
Repository string
TagOrDigest string
}
ResolvedOCIRef holds the result of resolving an OCI reference against a mirror configuration.
