Error: no Auth Provider found for name "gcp"

[cig0]

Hi,

I got this error message when trying to list the namespaces of my GKE cluster; please find below a sanitised version of ~/.kube/config:

% cat ~/.kube/config
apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: blah
    server: https://localhost:6443
  name: default
- cluster:
    certificate-authority-data: blah
    server: https://1.2.3.4
  name: gke_cluster
contexts:
- context:
    cluster: gke_cluster
    namespace: default
    user: gke_cluster
  name: gke_cluster
- context:
    cluster: default
    user: default
  name: minikube
current-context: gke_cluster
kind: Config
preferences: {}
users:
- name: default
  user:
    password: blah
    username: blah
- name: gke_cluster
  user:
    auth-provider:
      config:
        access-token: token_blah
        cmd-args: config config-helper --format=json
        cmd-path: /Users/cig0/Applications/google-cloud-sdk/bin/gcloud
        expiry: "blah"
        expiry-key: '{.credential.token_expiry}'
        token-key: '{.credential.access_token}'
      name: gcp

It is worth noting that I'm able to work with this context/cluster using kubectl or other CLI tools.

% kubecm version
Version: 0.13.0
GoOs: darwin
GoArch: amd64

Thanks! 🙏

Did this error occur in older versions?
This error is thrown by client-go.

[sunny0826]

for your kubeconfig, your context named gke_cluster, Can you describe your operation in detail?

Hi @sunny0826,

There's no much more to say about it, really.

The configuration I reproduce here is a sanitized version of that config file, where I only removed the tokens and trimmed the tail of gke_cluster to remove sensible information -- everything else is exactly the same.

I realize tho that I haven't provided the command I issued when I got the error nor the full error output, so here it goes:

~ ✖1 ❯ k get ns

This issue appears to be an authentication issue with client-go, thank you for the tip, I will try to fix this.

[sunny0826]

This problem looks very similar to kubernetes/client-go#242, but I don't have GKE to test whether following the approach in ISSUE solves the problem.

[cig0]

I could help you with that part, let me know if you need me to test anything.

Incidentally if you happen to have access to GCP, you should be able to open a free-tier account: https://cloud.google.com/free

Thanks for the tip, Happy new year!

[sunny0826]

I've just tried to fix this on the master branch, can you pull the code from the master branch, compile and test it?

[sunny0826]

You can try the v0.13.1 version and look forward to your feedback.
