BuildConfigFromConfigFile explanation missing

[marchenko1985]

Hello, I'm trying to run code copied from examples but got Unhandled Exception: k8s.Exceptions.KubeConfigException: User: X does not have appropriate auth credentials in kubeconfig

Can not find instructions in readme how should we run code locally agains google cloud kubernetes

I do have ~/.kube and commands like kubectl get pods are working as expected

cloud you please paste your config for debug?

the sdk should have same behavior as kubectl

[marchenko1985]

do you mean .kube/config here you go:

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: ****************************=
    server: https://X.X.X.X
  name: gke_project_id_europe-west1-b_cluster
contexts:
- context:
    cluster: gke_project_id_europe-west1-b_cluster
    user: gke_project_id_europe-west1-b_cluster
  name: gke_project_id_europe-west1-b_cluster
current-context: gke_project_id_europe-west1-b_cluster
kind: Config
preferences: {}
users:
- name: gke_project_id_europe-west1-b_cluster
  user:
    auth-provider:
      config:
        access-token: ******************************
        cmd-args: config config-helper --format=json
        cmd-path: /Users/mac/dev/google-cloud-sdk/bin/gcloud
        expiry: 2018-02-04T12:51:26Z
        expiry-key: '{.credential.token_expiry}'
        token-key: '{.credential.access_token}'
      name: gcp

I just replaced some thing that might be important, hope that helps. Feel free to ask me for any additional information if needed

[tg123]

auth-provider is not supported at the time.

😢

[tg123]

by the way
you may want try a workaround:
pass Token filed to sdk

[marchenko1985]

@tg123 may you please describe it it more details? it seems like it might be a good addition to readme

[tg123]

@mac2000 did not tested

get token from https://cloud.google.com/docs/authentication/production#obtaining_credentials_on_compute_engine_kubernetes_engine_app_engine_flexible_environment_and_cloud_functions first

create a client from KubernetesClientConfiguration { Host = gke_cluster , AccessToken = token above }

[marchenko1985]

Arghhh, it was painful

So from docs I we able to get default access token, so even do not need any google auth stuff

But then got macos related troubles with ssl verification

And only then I have realized what it should be done, so if you are running kubernetes inside google cloud and just wish to play around with api and wish not to configure everything all you should do:

$ kubectl proxy
Starting to serve on 127.0.0.1:8001

And in your program:

var config = new KubernetesClientConfiguration {  Host = "http://127.0.0.1:8001" };

And everything will start working immediately :)

Not sure if it should be mentioned somewhere in readme or not

[samuela]

What's the production-ready approach here? Using kubectl proxy seems fine for development but the README indicates that it's not appropriate for production.

[brendandburns]

@samuela someone needs to write support for GCP for this library.
