I am following step written it the official tutorial Try out Halyard on GKE

I am trying the deployment step but the hal deploy apply is not working.

I ran this command and it returned no error like below.

hal config deploy edit     --account-name my-k8s-account     --type distributed

+ Get current deployment
  Success
+ Get the deployment environment
  Success
- No changes supplied.

After this command, I ran this command hal deploy apply. But the Prep deployment fails and return this error.

! ERROR Unable to communicate with your Kubernetes cluster: Failure
  executing: GET at: https://35.200.120.197/api/v1/namespaces. Message: 
  Forbidden!
  User gke_helm-gke-test_asia-northeast1-b_helm-test doesn't have permission.
  namespaces is forbidden: User "client" cannot list namespaces at the cluster
  scope: Unknown user "client"..

How can I solve this problem?

My hal version is

$ hav -v
0.48.1-20180413145934
