replace kube-core rendering with openshift operators render #420

mfojtik · 2018-10-05T14:03:32Z

This change moves us away from kube-core renderer and use the kube-apiserver, kube-controller-manager and kube-scheduler operator renderers to gather all necessary bootstrap manifests.

@abhinavdahiya @smarterclayton this is what we want and we should make working.

@smarterclayton how are we supposed to handle this? :-) Also what is the preferred registry for our images? The RHCOS seems to have RH registry hardcoded as default, so using the :latest tag does not work and we really don't want to pin this into stable tag, otherwise we won't be able to test the changes in our operator images....

I guess we want all images in quay.io at some point but we want a knob to switch that to registry.svc.ci.openshift.org for the CI?

so the kube-core-operator installs these things in addition to api

1. kube-proxy
2. kube-dns
3. pod-checkpointer

What is the plan for these?

@sjenning this is for you. We have self-signed kubelet serving certs right now. I.e. the kube-apiserver->kubelet communication is insecure because the kubelet identity is not checked.

This is the old kube-core behaviour btw. So we are just copying that here, but should do better. I read @LiGgit commenting somewhere that up to kube 1.10 we don't support CSRs for properly signed kubelet serving certs. Has this changed upstream in 1.11 or 1.12?
