Add Kubernetes cluster created by Minikube on Windows

I want to get answers for below questions.

  • Is it possible to add an existing cluster without CA certificate like curl --insecure option.
  • I wonder below approach makes sense.
    • If yes, what I should do more?
    • If no, I want a guide for adding cluster.

The kube cluster is created by minikube on Windows. So its IP is internal like ‘’.

I installed Nginx to access my machine, and configured reverse proxy.

But it’s stuck with returning authorization problem.

There was a problem authenticating with your cluster. Please ensure your CA Certificate and Token are valid.

I tested requesting API by using curl command, and the result is like below.

So I can figure out reason, which is caused by CA certificate.

When the request is sent to my https://my_public_ip/path, nginx send it to minikube_ip through reverse proxy.

The nginx configuration is below.

server {
    listen       443 ssl;
    server_name  minikube;

    ssl_certificate      user_home_folder\.minikube\ca.crt;
    ssl_certificate_key  user_home_folder\.minikube\ca.key;
    ssl_session_cache    shared:SSL:1m;
    ssl_session_timeout  5m;

    ssl_ciphers  HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers  on;

	location /path {
		rewrite ^/path(/.*)$ $1 break;
		proxy_set_header proxied nginx;
		proxy_pass	https://minikube_ip:port/;
