It's isn't obvious to me what Docker does that we haven't been able to do for some time now.

To be honest, me also. I don't even use Docker either but it helps in conversations to keep it simple.
Since it isn't obvious to your, Docker and friends also have an entire content management system (pulling, pushing, tagging images and layers) as well as a build system.
