Create Anthos GKE on-prem admin and user cluster on PowerFlex rack

  • To create the admin and user cluster, complete the following steps:

    1. SSH to the admin workstation from the deployment workstation.
    1. For the admin cluster, modify the admin-cluster.yaml file to match your environment-specific variable. For detailed information, see Admin cluster configuration file.
    2. Validate the admin cluster configuration file using gkectl check-config command.

    gkectl check-config --config admin-cluster.yaml
    1. Initialize your vSphere environment using gkectl prepare command.

    gkectl prepare --config admin-cluster.yaml --skip-validation-all
    1. Create the admin cluster using the gkectl create admin command.

    gkectl create admin --config admin-cluster.yaml
    1. For the user cluster, modify the user-cluster.yaml file to match your environment-specific variable. For detailed information, see User cluster configuration file.
    2. Validate the user cluster configuration file using gkectl check-config command.

    gkectl check-config --kubeconfig [ADMIN_CLUSTER_KUBECONFIG] --config user-cluster.yaml

    where, [ADMIN_CLUSTER_KUBECONFIG] is the path of the kubeconfig file for your admin cluster.

    1. Create the user cluster using the gkectl create cluster command.

    gkectl create cluster --kubeconfig [ADMIN_CLUSTER_KUBECONFIG] --config user-cluster.yaml
    1. Verify the successful creation of admin cluster.

    kubectl get nodes --kubeconfig [ADMIN_CLUSTER_KUBECONFIG]
    1. Verify the successful creation of user cluster.

    kubectl get nodes --kubeconfig [USER_CLUSTER_KUBECONFIG]

    Results: The user cluster would be registered with Google Cloud once the cluster is created successfully.

    1. Log in to Google cloud > Kubernetes Engine > Clusters to verify the results.

    1. Select a cluster and click Login. You are prompted to choose a method you want to use for authentication of the cluster.
      • Token
      • Basic authentication
      • Authenticate with Identity Provider configured for the cluster

    Select the method of your choice and login to view the cluster overview.

    For detailed information, see Logging in to a cluster from Cloud Console.

    1. For complete detail of the cluster, select Kubernetes cluster details > Nodes.

    Note: The Kubernetes cluster nodes for Anthos on-prem clusters are running as vSphere VMs on PowerFlex system.

    1. (Optional) Check if the Kubernetes cluster nodes in the GCP console has the same name as the worker node VMs running on PowerFlex rack.
