Functions ¶

func GetID ¶

func GetID(image string) string

GetID returns the md5sum based ID for given image. If a recognized ID is passed, it is returned.

func GetPath ¶

func GetPath(name string) string

GetPath returns the path for given image name or id.

func Inspect ¶

func Inspect(images []string, format string) (string, error)

Inspect will return a JSON or a formatted string describing the input images.

func Pull ¶

func Pull(image string, quiet bool) (string, error)

Pull will pull a given image and save it to ImageDir. This function uses github.com/google/go-containerregistry/pkg/crane to pull the image's manifest, and performs the downloading of each layer separately. Each layer is deduplicated between images in order to save space, using hardlinks. If quiet is specified, no output nor progress will be shown.
