Why is he right? Docker is good software but it's not that good. The implementation is all over the place and there are several implementations of the docker image registry for absolutely no good reason. Implementation defined standards are not a good thing and as it stands docker is an implementation defined standard. The larger community wins if there is an open and documented standard and that's exactly what the CoreOS guys are doing. Vendors of container related software should be competing on features and not trying to reverse engineer each others' implementations.
