Securely connect to your GKE control plane (master) using Tailscale

April 4, 2023

TLDR

To securely connect to you GKE control plane using private IPs only: 1) set up a Compute Engine VM, install Tailscale and advertise the route to the GKE control plane, and 2) make sure the client is in the same tailnet and fetch the cluster credentials with the --internal-ip flag.
