[feature request] The k8s version problem involved in yurtadm join

[windydayc]

When using yurtadm join , the kubeadm, kubelet will be downloaded from here, and their versions will be the same as the installed kubernetes version.

However, in preflight phase, it will check kubelet version, but here the kubelet version is restricted to be above 1.21.0, that is to say, if you want to use yurtadm join, the k8s version must be above 1.21.0.

There is currently a need for a way to solve this problem.

@windydayc how about post a pull request to fix this problem at first? maybe we can define MinimumKubeletVersion to v1.18.0

The code in pkg/util/kubernetes/kubeadm is copied from the kubeadm v1.22.3 source code, from #864.

Is it feasible to directly modify the imported kubeadm source code in this way?

@windydayc yurtadm join should be used for K8s from v1.18+, so it's need to adjust it. Do you have any other solutions?

OK. I haven't thought of another solution yet.
