I thought they didn't make private registries available because it would "fragment the ecosystem"
Here's the conversation I saw:
https://stackoverflow.com/questions/33054369/how-to-change-t...
pointing to this:

and also there was this comment:
"It turns out this is actually possible, but not using the genuine Docker CE or EE version.
You can either use Red Hat's fork of docker with the '--add-registry' flag or you can build docker from source yourself with registry/config.go modified to use your own hard-coded default registry namespace/index."
No you have misunderstood the issue. You can use any registry, just write out the domain for it, this has always worked and is very widely used. Red Hat changed the default if you don't specify a FQDN, before they decided not to ship Docker at all.
I understand that point, but it makes it harder to not "accidentally" pull from a public registry with intertwined docker images (which most people use)
