BUG REPORT

Versions

kubeadm version (use kubeadm version): v1.14

Environment:

• Kubernetes version (use kubectl version): v1.14
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
• Kernel (e.g. uname -a):
• Others:

What happened?

It is unable to customize readOnlyPort via kubeadm init phase upload-config kubelet --config kubeadm.yaml.

What you expected to happen?

readOnlyPort should be customizable via kubeadm init phase upload-config.

How to reproduce it (as minimally and precisely as possible)?

kubeadm init phase upload-config kubelet --config kubeadm.yaml

apiVersion: kubelet.config.k8s.io/v1beta1
kind: KubeletConfiguration
readOnlyPort: 10255

Anything else we need to know?

This is caused by kubeadm's default behaviour. But I think it would be better not to default the configurations on kubeadm side (even if it will be deprecated in the future), otherwise, it will break users' expectation.
