1. Deploy the volcano helm chart on Google Kubernetes Engine (GKE)


    To deploy the Volcano Helm chart on Google Kubernetes Engine (GKE), you would need to perform the following high-level steps:

    1. Set up a GKE cluster: Provide the necessary configuration to define and provision a GKE cluster.
    2. Install Helm and Tiller: Ensure Helm and Tiller are set up in the cluster. However, if you're using Helm 3, Tiller is not needed.
    3. Add the Volcano Helm chart repository: Volcano Helm chart must be located in a repository that you add for Helm to manage your applications.
    4. Deploy Volcano with Helm: Use Helm to deploy the Volcano Helm chart to the GKE cluster.

    Here is a Pulumi TypeScript program that demonstrates these steps:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Set up a GKE cluster const cluster = new gcp.container.Cluster("volcano-gke-cluster", { initialNodeCount: 1, // The following are default values and could be tuned depending on your needs: minMasterVersion: "latest", // Optionally set the minimum Kubernetes master version nodeVersion: "latest", // Optionally set the Kubernetes node version nodeConfig: { machineType: "n1-standard-1", // Standard machine type, you can change this based on your needs oauthScopes: [ // Set the proper OAuth scopes for the VM instances "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/service.management.readonly", "https://www.googleapis.com/auth/servicecontrol", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring", ], }, }); // Step 2: Install Helm and Tiller // For Helm 3, Tiller is not required. You would use the Helm CLI to set up Volcano directly. // This step can be skipped if you're using Helm 3. // Step 3: Set up Kubernetes provider to install the Volcano Helm Chart const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw, // Use the kubeconfig from the generated GKE cluster }); // Step 4: Deploy Volcano using Helm const volcanoChart = new k8s.helm.v3.Chart("volcano", { chart: "volcano", // Name of the Helm Chart version: "1.0.1", // Version of the Helm Chart, verify the version number fetchOpts: { repo: "https://volcano-sh.github.io/charts", // The repository containing Volcano Helm Charts }, }, { provider: k8sProvider }); // Export the Cluster name and Kubeconfig export const clusterName = cluster.name; export const kubeConfig = cluster.kubeConfigRaw;

    In this program:

    • We first declare our GKE cluster resource called volcano-gke-cluster, specifying initial settings including the count of nodes, versions of Kubernetes master and node, and the machine type.

    • We create a provider that establishes how to communicate with the GKE cluster (k8sProvider) using the kubeconfig.

    • We then use the k8s.helm.v3.Chart resource to deploy the Volcano Helm Chart. We specify the chart name, version, and the repo where the Helm chart can be found. Ensure to check the correct version number as needed.

    • Finally, we export the cluster name and kubeconfig which can be used to access the Kubernetes cluster outside of Pulumi.

    For full documentation on the resources used here, you can refer to:

    Please make sure you have Pulumi installed and configured with GCP credentials. You will also need to have kubectl and Helm installed on your machine to work with the Kubernetes cluster and deploy the Helm chart, respectively. After running the program with pulumi up, you can use pulumi stack output kubeConfig to get the kubeconfig file for accessing your cluster with kubectl.
