Functions

func DecodeLabel

func DecodeLabel(image imgutil.Image, label string, v interface{}) error

func FromLayoutPath

func FromLayoutPath(parentPath string) (v1.Image, string, error)

FromLayoutPath takes a path to a directory (such as <layers>/extended/run) containing a single image in "sparse" OCI layout format, and returns a v1.Image along with the path of the image (such as <layers>/extended/run/sha256:<sha256>) or an error if the image cannot be loaded. The path is helpful for locating the image when we only know the digest of the config, such as for local images.

func SyncLabels

func SyncLabels(sourceImg imgutil.Image, destImage imgutil.Image, test func(string) bool) error

Types

type Handler

type Handler interface {
	InitImage(imageRef string) (imgutil.Image, error)
	Kind() string
}

func NewHandler

func NewHandler(docker client.CommonAPIClient, keychain authn.Keychain, layoutDir string, useLayout bool) Handler

NewHandler creates a new Handler according to the arguments provided, following these rules: - WHEN layoutDir is defined and useLayout is true then it returns a LayoutHandler - WHEN a docker client is provided then it returns a LocalHandler - WHEN an auth.Keychain is provided then it returns a RemoteHandler - Otherwise nil is returned
