Description

Currently image validation is done assuming that the image's filename will have digest (SHA-512) information. This is not part of the spec
(https://github.com/appc/spec/blob/master/spec/discovery.md).

The spec specifies the tuple <image name, labels> as unique identifier for discovering an image.
