I created it using the consul api (https://github.com/hashicorp/consul/blob/v1.6.2/api/session.go#L72)

I suspect that the node is always in the Leaving state, which causes the `reconcilemember` function to be unable to execute all the time, as a result, the node serfHealth...

I encountered a similar problem, when I modified the controlplane replica from 1 to 3, it failed. KCP logs show: ``` I0707 00:32:51.445862 1 controller.go:350] controller-runtime/manager/controller/kubeadmcontrolplane "msg"="Scaling up control plane"...

I ensure the NTP is good. However, In the same environment, after testing, alpha3(should be v0.3.11) is ok, alpha4(v0.3.16) not.

All commands behave the same way. For beginners, there should be more friendly prompts for some commands, e.g.: `kubeadm config ...` Simple ideas :smiley: :

yes.

Thanks. I will do it.
