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


    To deploy the ceph-client Helm chart on Google Kubernetes Engine (GKE), you will need to follow a few steps:

    1. Set up a GKE Cluster: To deploy any applications on Kubernetes, including Helm charts, you first need a Kubernetes cluster. Google Kubernetes Engine (GKE) provides a managed environment for deploying, managing, and scaling your containerized applications using Google infrastructure.

    2. Install Helm: Helm is a package manager for Kubernetes that allows you to deploy applications described in Helm charts — which are templates describing a set of Kubernetes resources.

    3. Add Helm Chart Repository: If the ceph-client chart is hosted in a Helm repository, you will need to add that repository to your Helm installation.

    4. Deploy the Helm Chart: Once you have the repository added, you can deploy the Helm chart to your cluster by running the appropriate helm install command.

    Below is a Pulumi program in TypeScript that demonstrates these steps. This program uses @pulumi/gcp for the GKE cluster creation and @pulumi/kubernetes for deploying the Helm chart.

    import * as pulumi from "@pulumi/pulumi"; 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("my-gke-cluster", { initialNodeCount: 2, minMasterVersion: "latest", nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-1", oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring" ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig to access the cluster with kubectl export const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Step 2: Set up the Kubernetes provider to deploy Helm charts to the created cluster const k8sProvider = new k8s.Provider("gke-k8s", { kubeconfig: kubeconfig, }); // Step 3: Add the Helm chart repository (This assumes the chart is in the 'ceph' repository; adjust as necessary) const cephRepo = new k8s.helm.v3.Repository("ceph-repo", { name: "ceph", url: "https://example.com/charts", // Replace with the actual repository URL }, { provider: k8sProvider }); // Step 4: Deploy the 'ceph-client' Helm chart from the repository const cephClientChart = new k8s.helm.v3.Chart("ceph-client", { chart: "ceph-client", version: "1.2.3", // Replace with the desired chart version fetchOpts: { repo: cephRepo.url, }, }, { provider: k8sProvider }); // Export the Helm chart deployment status export const cephClientChartStatus = cephClientChart.status;

    In this Pulumi program:

    • A GKE cluster is created with 2 nodes using the n1-standard-1 machine type.
    • A kubeconfig file is generated for accessing the created cluster using kubectl or any other Kubernetes client.
    • The Kubernetes provider is set up using the generated kubeconfig file.
    • A Helm chart repository is added using the cephRepo resource.
    • The ceph-client Helm chart is deployed from the added repository to the GKE cluster.

    Make sure you replace "https://example.com/charts" with the actual URL of the Helm repository where the ceph-client chart is located and use the correct version for the chart.

    When you run the above program with Pulumi, the state of your deployment is saved in Pulumi's state management system. You can track, update, or delete your deployments with simple Pulumi CLI commands.

    This program needs to be run in a directory with a Pulumi.yaml file where you have your Pulumi project set up. You also need to have Pulumi CLI installed and authenticated with a GCP account. If you want to execute the Pulumi program, you can compile it using tsc (TypeScript Compiler) and then use Pulumi CLI commands like pulumi up to perform the deployment.

    Please ensure that you consult the documentation and understand the configurations for the specific version of the ceph-client Helm chart that you are deploying, as it might require additional setup or configurations.
