Hi @hafe. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

by default etcd installed by kubespray, not kubeadm

need to check etcd_kubeadm_enabled==true before remove thish options

I thought the config file section controlled if kubeadm should manage etcd or not. Does anyone know?

What luckySB means is that you probably need to add a conditional thing, as this flag should only be removed when etcd_kubeadm_enabled is set to true

I understand but my question is why would that be needed?

If kubeadm is not managing etcd why would you have tell it to not update etcd?

Will etcd_version will be respected for the upgrade by kubeadm?

I believe that is determined by the kubeadm config file laid down by kubespray so yes
