If we override the default value and retag the preload after loading, we can change even the existing releases.

--image-repository=registry.k8s.io

docker tag k8s.gcr.io/pause:3.2 registry.k8s.io/pause:3.2

But it will go in a separate PR, since it is a separate feature. Changing the current releases is a good start...

The binaries were changed here, to use dl.k8s.io:

• Download binaries from dl.k8s.io instead of GCS #15840

@afbjorklund I believe this PR been replaced by #16029 and we could safely close this one, if you agree

[spowelljr]

Due to #16017 we're always going to be using the new registry so this PR is no longer needed. Superseded by #16029

[afbjorklund]

It was mostly if you wanted a more fine-grained report on when kubeadm default was bumped ?

But it should be safe to supply the kubernetes registry as a parameter, even when it is the default...
