Tip: kube-apiserver can't start after adding a parameter


We add a new oidc parameter for kube-apiserver to integrate with openID Dex.

The parameter is  --oidc-groups-prefix=oidc:

After that, kubelet can't start kube-apiserver static pod, and no obvious error reported


The issue is to ":"  which is special character. It prevents kubelet to parse the parameter.

The right way is to quote it.  "--oidc-groups-prefix=oidc:" See more details in this github thread
