Deploy KubeSphere on GKE

KubeSphere+GKE

This guide walks you through the steps of deploying KubeSphere on Google Kubernetes Engine.

Prepare a GKE Cluster

  • A standard Kubernetes cluster in GKE is a prerequisite of installing KubeSphere. Go to the navigation menu and refer to the image below to create a cluster.

    create-cluster-gke

  • In Cluster basics, select a Master version. The static version 1.15.12-gke.2 is used here as an example.

    select-master-version

  • In default-pool under Node Pools, define 3 nodes in this cluster.

    node-number

  • Go to Nodes, select the image type and set the Machine Configuration as below. When you finish, click Create.

    machine-config

Note

  • To install KubeSphere 3.3 on Kubernetes, your Kubernetes version must be v1.19.x, v1.20.x, v1.21.x, * v1.22.x, * v1.23.x, and * v1.24.x. For Kubernetes versions with an asterisk, some features of edge nodes may be unavailable due to incompatability. Therefore, if you want to use edge nodes, you are advised to install Kubernetes v1.21.x or earlier.
  • 3 nodes are included in this example. You can add more nodes based on your own needs especially in a production environment.
  • The machine type e2-medium (2 vCPU, 4GB memory) is for minimal installation. If you want to enable pluggable components or use the cluster for production, please select a machine type with more resources.
  • For other settings, you can change them as well based on your own needs or use the default value.
  • When the GKE cluster is ready, you can connect to the cluster with Cloud Shell.

    cloud-shell-gke

Install KubeSphere on GKE

  • Install KubeSphere using kubectl. The following commands are only for the default minimal installation.

    kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.1/kubesphere-installer.yaml
    
    kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.3.1/cluster-configuration.yaml
    
  • Inspect the logs of installation:

    kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f
    
  • When the installation finishes, you can see the following message:

    #####################################################
    ###              Welcome to KubeSphere!           ###
    #####################################################
    Console: http://10.128.0.44:30880
    Account: admin
    Password: [email protected]
    NOTES:
      1. After logging into the console, please check the
        monitoring status of service components in
        the "Cluster Management". If any service is not
        ready, please wait patiently until all components
        are ready.
      2. Please modify the default password after login.

Access KubeSphere Console

Now that KubeSphere is installed, you can access the web console of KubeSphere by following the steps below.

  • In Services & Ingress, select the service ks-console.

    ks-console

  • In Service details, click Edit and change the type from NodePort to LoadBalancer. Save the file when you finish.

    lb-change

  • Access the web console of KubeSphere using the endpoint generated by GKE.

    access-console

    Tip

    Instead of changing the service type to LoadBalancer, you can also access KubeSphere console via NodeIP:NodePort (service type set to NodePort). You may need to open port 30880 in firewall rules.
  • Log in to the console with the default account and password (admin/[email protected]). In the cluster overview page, you can see the dashboard.

Enable Pluggable Components (Optional)

The example above demonstrates the process of a default minimal installation. To enable other components in KubeSphere, see Enable Pluggable Components for more details.
