Cannot use kubectl after kk create cluster #371

Open LinuxSuRen opened 3 years ago

LinuxSuRen commented 3 years ago

When I finished the cluster creating task via kk create cluster --with-kubesphere --with-kubernetes v1.17.9

I try to execute a simple command which is kubectl get ns. But errors happend. You can see the output below:

Unable to connect to the server: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kubernetes")

A special case that is worth noticing. I run the below commands many times on my machine.

sudo kk create cluster --with-kubesphere --with-kubernetes v1.17.9
sudo kk delete cluster

You can try to execute kubectl get ns --kubeconfig /etc/kubernetes/admin.conf. If the above command can work, it is possible that kubeconfig was not updated.

As you said. It works well via kubectl get ns --kubeconfig /etc/kubernetes/admin.conf.

I did more tests. First, delete the .kube directory via rm -rf ~/.kube. Then install it again. After the installation was done. I got the following errors: The connection to the server localhost:8080 was refused - did you specify the right host or port?

Guest what? I don't have the .kube directory. So I guess this should be a bug exists.

OK, We'll check this issue later.
