Cloud Run API kubectl compatibility fix

This is an experimental repository and is not meant to be used.

This client-side tool patches the currently incomplete parts of the Cloud Run (fully hosted) API (that is {region}-run.googleapis.com) by running a proxy server locally.

This proxy will works by:

• Kubernetes discovery API requests (/api, /apis etc) are proxied to a Cloud Run on GKE cluster (hardcoded address) that offers them publicly.

• other requests about managing these resources are forwarded to us-central1-run.googleapis.com.

To run this proxy, simply compile and execute the Go program and copy the CA certificate into the kubeconfig file. Running the program starts a local kube-apiserver proxy at :6443 on HTTPS using a self-signed certificate (which you need to trust in your kubeconfig).

Example kubeconfig file to point kubectl to this local proxy server:

apiVersion: v1
kind: Config
current-context: gcp_cloudrun_us-central1
clusters:
-  name: gcp_cloudrun_us-central1
   cluster:
    certificate-authority-data: "" # PASTE FROM THE COMMAND OUTPUT
    server: https://localhost:6443
contexts:
- name: gcp_cloudrun_us-central1

    cluster: gcp_cloudrun_us-central1
