I was setting up my new Mac for my eks environment. After the installation of kubectl, aws-iam-authenticator and the kubeconfig file placement in default location. I ran the command kubectl command and got this error mentioned below in command block.
My cluster uses v1alpha1 client auth api version so basically i wanted to use the same one in my Mac as well.
I tried with latest version (1.23.0) of kubectl as well, still the same error. Whereas When i tried to do with aws-iam-authenticator (version 0.5.5) I was not able to download lower version.
Can someone help me to resolve it?
% kubectl version
Client Version: version.Info{Major:"1", Minor:"20", GitVersion:"v1.20.0", GitCommit:"af46c47ce925f4c4ad5cc8d1fca46c7b77d13b38", GitTreeState:"clean", BuildDate:"2020-12-08T17:59:43Z", GoVersion:"go1.15.5", Compiler:"gc", Platform:"darwin/amd64"}
Unable to connect to the server: getting credentials: exec plugin is configured to use API version client.authentication.k8s.io/v1alpha1, plugin returned version client.authentication.k8s.io/v1beta1
Thanks and Regards, Saravana
I have the same problem
You're using aws-iam-authenticator 0.5.5, AWS changed the way it behaves in 0.5.4 to require v1beta1.
It depends on your configuration, but you can try to change the K8s context you're using to v1beta1
by checking your kubeconfig file (usually in ~/.kube/config) from client.authentication.k8s.io/v1alpha1 to client.authentication.k8s.io/v1beta1
Otherwise switch back to aws-iam-authenticator 0.5.3 - you might need to build it from source if you're using the M1 architecture as there's no darwin-arm64 binary built for it
