Describe the solution you'd like
[A clear and concise description of what you want to happen.]
It seems capz is not using --config for kubelet parameters currently. Is it in the roadmap?

Flag --container-runtime-endpoint has been deprecated, This parameter should be set via the config file specified by the Kubelet's --config flag

@lzhecheng this might be a better question for the kubeadm folks. CAPZ is not configuring kubelet, only using kubeadm init and kubeadm join to join the nodes.

is container-runtime-endpoint getting set as an extra kubelet arg in the template you're using in this context?

No, this job is using standard capz cluster template. So args should be only azure-container-registry-config and cloud-provider. I don't know where this arg comes from...

It gets set by kubeadm https://github.com/kubernetes/kubernetes/blob/714e77595c8b19b693925bda2a96ab80c307d38f/cmd/kubeadm/app/phases/kubelet/flags.go#L79

looks like this is already tracked in kubernetes/kubeadm#2902
