title: Can't connect to container cluster: environment variable HOME or KUBECONFIG must be set when running gcloud get credentials
body: <p>For some reason I can't connect to the cluster. Having followed the instructions per google container-engine after setting up the cluster, I get the following error: </p>
  
  <p>ERROR: (gcloud.container.clusters.get-credentials) environment variable HOME or KUBECONFIG must be set to store credentials for kubectl</p>
  
  <p>When running this command:  gcloud container clusters get-credentials [my cluster name] --zone us-central1-b --project [my project name]</p>
  
  <p>Any ideas how I should be setting the variable HOME or KUBECONFIG. I couldn't find anything specific for container-engine.</p>
