Kubernetes suddenly stopped being able to connect to server

I was successfully able to connect to the kubernetes cluster and work with the services and pods. At one point this changed and everytime I try to connect to the cluster I get the following error:

PS C:\Users\xxx> kubectl get pods
Unable to connect to the server: error parsing output for access token command "C:\\Program Files (x86)\\Google\\Cloud SDK\\google-cloud-sdk\\bin\\gcloud.cmd config config-helper --format=json": yaml: line 4: could not find expected ':'

I am unsure of what the issue is. Google unfortunately doesn't yield any results for me either.

I have not changed any config files or anything. It was a matter of it working one second and not working the next.

Thanks.

It looks like the default auth plugin for GKE might be buggy on windows. kubectl is trying to run gcloud to get a token to authenticate to your cluster. If you run kubectl config view you can see the command it tried to run, and run it yourself to see if/why it fails.

As Alexandru said, a workaround is to use Google Application Default Credentials. Actually, gcloud container has built in support for doing this, which you can toggle by setting a property:

gcloud config set container/use_application_default_credentials true Try running this or set environment variable

%CLOUDSDK_CONTAINER_USE_APPLICATION_DEFAULT_CREDENTIALS% to true.

Referenced from here

The workaround for this issue being:

gcloud container clusters get-credentials <cluster-name> If you dont know your cluster name find it by gcloud container clusters list Finally, if those don't have issues, do gcloud auth application-default login and login with relative details
