> A common way to specify a Docker image with the docker engine is through
> {{repo:tag}}, which is convenient and sufficient for most people in most
> scenarios. However this combination is neither precise nor immutable.
> For this reason, it's possible when an image with a {{repo:tag}} already
> cached locally on an agent host and a task requiring this {{repo:tag}}
> arrives, it's using an image that's different than the one the user intended.
> Docker CLI already supports referring to an image by {{repo@id}}, where the
> ID can have two forms:
> * v1 Image ID
> * digest
> Native Mesos provisioner should support the same for Docker images. IMO it's
> fine if image discovery by ID is not supported (and thus still requiring
> {{repo:tag}} to be specified) (looks like [v2
> registry|http://docs.docker.com/registry/spec/api/] does support it) but the
> user can optionally specify an image ID and match it against the cached /
> newly pulled image. If the ID doesn't match the cached image, the store can
> re-pull it; if the ID doesn't match the newly pulled image (manifest), the
> provisioner can fail the request without having the user unknowingly running
> its task on the wrong image.
