Functions

func GuessManifestMIMEType

func GuessManifestMIMEType(manifest []byte) string

GuessManifestMIMEType guesses MIME type of a manifest and returns it _if it is recognized_, or "" if unknown or unrecognized. FIXME? We should, in general, prefer out-of-band MIME type instead of blindly parsing the manifest, but we may not have such metadata available (e.g. when the manifest is a local file).

func ManifestDigest

func ManifestDigest(manifest []byte) (string, error)

ManifestDigest returns the a digest of a docker manifest, with any necessary implied transformations like stripping v1s1 signatures.
