Managing clusters

This page describes how to manage your GKE on-prem clusters.

Before you begin

1. SSH into your admin workstation:

   ssh -i ~/.ssh/vsphere_workstation ubuntu@[IP_ADDRESS]
   

2. Log in to Google Cloud using your account credentials:

   gcloud auth login

3. Set a default project. Setting a default Google Cloud causes all gcloud CLI commands to run against the project, so that you don't need to specify your project for each command:

   gcloud config set project [PROJECT_ID]
   

   Replace [PROJECT_ID] with your project ID. (You can find your project ID in Google Cloud console, or by running gcloud config get-value project.)

Viewing your clusters

kubectl get clusters --kubeconfig [ADMIN_CLUSTER_KUBECONFIG]

Connecting to your clusters

If you want to connect to your clusters, you have two options:

• You can SSH into cluster nodes.
• Your user clusters are automatically registered to your Google Cloud project when you create them. This means you can view and log in to clusters from the Google Cloud console.

Checking cluster version

kubectl get cluster --kubeconfig [USER_CLUSTER_KUBECONFIG] -o yaml | grep bundle.gke.io/version

kubectl get pod -l api=clusterapi --kubeconfig [ADMIN_CLUSTER_KUBECONFIG] -o yaml -n kube-system | grep image:.*controller-manager
