• Variables
• func Image(ref name.Reference, options ...ImageOption) (v1.Image, error)
• func Write(tag name.Tag, img v1.Image) (string, error)

Variables

var GetImageLoader = func() (ImageLoader, error) {
	cli, err := client.NewEnvClient()
	if err != nil {
		return nil, err
	}
	cli.NegotiateAPIVersion(context.Background())
	return cli, nil
}

This is a variable so we can override in tests.

Functions

func Image

func Image(ref name.Reference, options ...ImageOption) (v1.Image, error)

Image provides access to an image reference from the Docker daemon, applying functional options to the underlying imageOpener before resolving the reference into a v1.Image.

func Write

func Write(tag name.Tag, img v1.Image) (string, error)

Write saves the image into the daemon as the given tag.

type ImageLoader interface {
	ImageLoad(context.Context, io.Reader, bool) (types.ImageLoadResponse, error)
}

type ImageSaver

type ImageSaver interface {
	ImageSave(context.Context, []string) (io.ReadCloser, error)
}

API interface for testing.
