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


    To deploy the Terracotta helm chart on Google Kubernetes Engine (GKE) using Pulumi, you'll perform several steps. I will guide you through each of them, providing explanations and code to achieve your goal.

    1. Set up a GKE cluster: First, you need a running Kubernetes cluster on GKE. Pulumi allows you to create a GKE cluster by defining appropriate resources.

    2. Install the Helm chart: After your cluster is up and running, you will need to use the Pulumi Kubernetes Provider to install the Terracotta helm chart.

    Step 1: Create a GKE Cluster

    The google-native.container/v1.Cluster resource is used from the google-native Pulumi provider to create a GKE cluster. This resource allows you to define your cluster's properties like its location, node pools, network policies, etc.

    Step 2: Deploying the Helm Chart

    Once the cluster is in place, you'll use the Pulumi Helm Release resource from the Kubernetes Provider to deploy the Terracotta helm chart onto your cluster. You need to set up a Kubernetes provider that points to the created GKE cluster to use the Kubernetes resources.

    Now let's look at the full Pulumi TypeScript program that combines these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision a GKE cluster const cluster = new gcp.container.Cluster("terracotta-cluster", { // Specify the location for your cluster location: "us-central1", minMasterVersion: "latest", // Use the latest GKE version initialNodeCount: 2, // Define the node configuration 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", ], }, }); // Expose the Kubeconfig for the GKE cluster 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: Create a Kubernetes provider instance using the GKE cluster's kubeconfig const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Step 3: Deploy the Terracotta Helm chart using the Kubernetes provider const terracottaChart = new k8s.helm.v3.Chart("terracotta", { chart: "terracotta", version: "x.y.z", // replace with the desired chart version fetchOpts: { repo: "http://path.to/your/helm/repo", }, }, { provider: k8sProvider }); // Export the Terracotta Helm deployment's status export const terracottaStatus = terracottaChart.status;


    • GKE Cluster: We create a GKE cluster with a specified name, location, GKE version, and node configuration, including machine type and OAuth scopes.
    • Kubeconfig Output: We create a Kubeconfig file that will be used to interact with our GKE cluster outside of Pulumi, for instance using kubectl.
    • Kubernetes Provider: We instantiate a Kubernetes provider that uses the created Kubeconfig to interact with our GKE cluster.
    • Helm Chart Deployment: We deploy the Terracotta helm chart to the GKE cluster using the Kubernetes provider.

    This program creates a GKE cluster and deploys the Terracotta helm chart to it. Replace x.y.z with the chart version you wish to deploy and http://path.to/your/helm/repo with the Terracotta Helm repository URL.

    You'll need to run this code using the Pulumi CLI. Make sure you have Pulumi installed and configured to access your GCP account. If you don't have a helm repo for Terracotta, you'll need to locate one or create your helm chart.

    To proceed, save this code to a file (e.g., index.ts), run pulumi up via the terminal in the directory containing your new Pulumi project, and follow the prompts to deploy your infrastructure.
