1. Deploy the ceph-provisioners helm chart on Google Kubernetes Engine (GKE)


    Deploying a Helm chart on a Google Kubernetes Engine (GKE) cluster typically involves several steps:

    1. Create a GKE Cluster: You would first need to create a GKE cluster where you want the Helm chart to be deployed.

    2. Helm Installation and Configuration: Once the GKE cluster is up and running, Helm needs to be installed and configured to manage Kubernetes applications.

    3. Deploy Helm Chart: After Helm is configured, you can then deploy the ceph-provisioners Helm chart onto the GKE cluster.

    Using Pulumi to automate this, it would involve writing code that will define the desired state for each of these steps. Below is an example TypeScript program that shows how you could use Pulumi to create a GKE cluster and deploy the ceph-provisioners Helm chart onto that cluster.

    Please ensure you have Pulumi installed and configured to access Google Cloud Platform before running this code.

    First, let's write a detailed explanation of each part of the program:

    • We will use the @pulumi/gcp package to create the GKE cluster.
    • We will use the @pulumi/kubernetes package to interact with the Kubernetes API, which is needed for the deployment of the Helm chart.
    • The KubernetesProvider resource is used to interact with the created GKE cluster specifically.
    • The helm.v3.Chart resource is used to deploy the ceph-provisioners Helm chart using the configured Kubernetes provider.

    Here's the Pulumi program written in TypeScript:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a GKE cluster const cluster = new gcp.container.Cluster("my-gke-cluster", { initialNodeCount: 2, minMasterVersion: "latest", nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-2", // or any other preferred machine type oauthScopes: [ "https://www.googleapis.com/auth/cloud-platform", // oAuth scopes that are required by the `ceph-provisioners` ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Step 2: Configure the Kubernetes provider using the created GKE cluster creds const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw, }); // Step 3: Deploy the `ceph-provisioners` helm chart using the Kubernetes provider const cephProvisionersChart = new k8s.helm.v3.Chart("ceph-provisioners", { chart: "ceph-provisioners", // Specify the Helm chart version if needed // version: "<CHART_VERSION>", // Include any custom values file (yaml) or configuration needed // values: {...}, }, { provider: k8sProvider }); // Export the status of the Helm release export const cephProvisionersStatus = cephProvisionersChart.status;

    To run this program:

    1. Save the code to a file named index.ts.
    2. Run pulumi up from the command line to create the GKE cluster and deploy the Helm chart.

    The output of the pulumi up command will show you a preview of the resources that Pulumi plans to create. If everything looks good, you can proceed to apply the changes.

    Make sure you have the necessary permissions and roles granted in your GCP account for creating and managing GKE clusters, and that you've correctly set up your gcloud CLI and Pulumi configuration. Additionally, ensure Helm is available in your execution environment if you intend to modify or interact with Helm charts beyond the scope of this deployment.

    Keep in mind that the ceph-provisioners Helm chart must be available in the Helm repository you're using, and it might require specific configuration options based on your cluster setup and needs.
