	if (image.contains(":")) {
	String imageName = image.split(":")[0];
	String imageVersion = image.split(":")[1];
	return Optional.of(new ServiceLocator.Service(

Images can, and should be specified using digest, rather than tags. Tags are mutable, so they aren't secure. Digests are immutable, and always point to the same image.

Full container path can look like: domain.org/dir-1/dir-n/name:tag@sha256:deadbeef

Below image names are valid and working:

• quay.io/cardil/wathola-forwarder:v0.7.0@sha256:5130875b448f6d4a8d1d422e83358c8a56a21466cbd51492e7ff4d5ebddb7d26
• quay.io/cardil/wathola-forwarder@sha256:5130875b448f6d4a8d1d422e83358c8a56a21466cbd51492e7ff4d5ebddb7d26
• quay.io/cardil/wathola-forwarder:v0.7.0

Now Judge-d looks only for tagged images. It should properly parse image address.
