how to set up kubectl on laptop for private GKE cluster and on prem private cluster

HTTP tunnel

On prem k8s cluster set up with bastion vm

  1. Create a bastion vm in your data center or in cloud with connectivity set up (usually vpn) to the on prem data center.
  2. Install tinyproxy on the bastion vm and pick a random port as it would be too easy for spam bot with default 8888, set up as systemd service according to https://nxnjz.net/2019/10/how-to-setup-a-simple-proxy-server-with-tinyproxy-debian-10-buster/. Make sure it works by validating with curl --proxy http://127.0.0.1:<tinyproxy-port> https://httpbin.org/ip. And I don't use any user authentication for proxy, so I locked down the firewall rules with my laptop IP/32.
  3. Download the kubeconfig file for the k8s cluster to your laptop
  4. From your laptop, run
HTTPS_PROXY=<bastion-external-ip>:<tinyproxy-port> KUBECONFIG=my-kubeconfig kubectl get nodes
