Functions ¶
func ConvertArch ¶ added in v1.2.0
Convert CLI options GOARCH and arch variant to recognized docker arch
func ConvertReference ¶
func ConvertReference(ctx context.Context, imgCache *cache.Handle, src types.ImageReference, sys *types.SystemContext) (types.ImageReference, error)
ConvertReference converts a source reference into a cache.ImageReference to cache its blobs
func ImageDigest ¶ added in v1.0.2
func ImageDigest(ctx context.Context, uri string, sys *types.SystemContext) (digest string, err error)
ImageDigest obtains the digest of a uri's manifest
func ParseImageName ¶
func ParseImageName(ctx context.Context, imgCache *cache.Handle, uri string, sys *types.SystemContext) (types.ImageReference, error)
ParseImageName parses a uri (e.g. docker://ubuntu) into it's transport:reference combination and then returns the proper reference
Types ¶
type ImageReference ¶
type ImageReference struct {
types.ImageReference
// contains filtered or unexported fields
}
ImageReference wraps containers/image ImageReference type
func (*ImageReference) NewImageSource ¶
func (t *ImageReference) NewImageSource(ctx context.Context, sys *types.SystemContext) (types.ImageSource, error)
NewImageSource wraps the cache's oci-layout ref to first download the real source image to the cache
