stern seems to be incompatible with GCP Kubernetes auth about stern HOT 4 CLOSED

Hi,

Stern should work with GKE clusters because GKE uses the client-go credential plugins mechanism. I have tested stern v1.25.0 with gke-gcloud-auth-plugin 0.5.3 on my GKE cluster, and it worked successfully.

Could you please try running gcloud container clusters get-credential to see if it fixes the issue? Your kubeconfig might not have been updated after installing the plugin.

gcloud container clusters get-credentials <CLUSTER> --region <REGION> --project <PROJECT>

from stern.

I checked ~/.kube/config and the settings seemed to be correct.
I ran gcloud container clusters get-credentials <CLUSTER>. It seems to have done a refresh.

❯ gcloud container clusters get-credentials apod-api                  
Fetching cluster endpoint and auth data.
kubeconfig entry generated for apod-api.

Now stern is working.

I'm glad the issue has been resolved 🎉

I believe that your old kubeconfig was likely using the deprecated gcp auth-provider as follows. The gcp auth-provider was removed in client-go 1.26.

- name: gke_api-project-xxxx
  user:
    auth-provider:
      name: gcp # removed in client-go 1.26

I think your new kubeconfig now correctly uses the new plugin mechanism exec.

- name: gke_api-project-xxxx
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1beta1
      args: null
      command: gke-gcloud-auth-plugin
      # ...

I am closing this as the issue has been resolved. If there are any further problems, please reopen.
