Images can be specified from either a local Docker daemon, or from a remote registry.
To specify a local image, prefix the image ID with 'daemon://', e.g. 'daemon://gcr.io/foo/bar'.
To specify a remote image, prefix the image ID with 'remote://', e.g. 'remote://gcr.io/foo/bar'.
If no prefix is specified, the local daemon will be checked first.

Tarballs can also be specified by simply providing the path to the .tar, .tar.gz, or .tgz file.`,
