1. Deploy the h2-database helm chart on Google Kubernetes Engine (GKE)


    To deploy the h2-database Helm chart on a Google Kubernetes Engine (GKE) cluster, you'll first need to make sure that you have a GKE cluster running. Pulumi allows you to describe and create infrastructure as code (IaC). If you haven't created a GKE cluster yet, you can do this with Pulumi as well.

    In our scenario, we'll assume you already have a GKE cluster in place. If not, you can use Pulumi to create one by using the google-native.container/v1.Cluster resource (documentation).

    After confirming that you have a Kubernetes cluster, we'll move on to deploying the h2-database Helm chart. For this, we'll utilize Pulumi's kubernetes.helm.v3.Chart class, which is part of Pulumi's @pulumi/kubernetes package (documentation).

    Here's what you'll need to deploy the Helm chart:

    1. Import necessary modules from the Pulumi SDK.
    2. Create a Helm Chart resource that points to the h2-database Helm chart.

    Below is a detailed TypeScript program that demonstrates deploying the h2-database Helm chart on an existing GKE cluster:

    import * as kubernetes from "@pulumi/kubernetes"; import * as gcp from "@pulumi/gcp"; // Initialize a new Pulumi Kubernetes provider that targets our GKE cluster. const gkeK8sProvider = new kubernetes.Provider("gkeK8s", { kubeconfig: gcp.container.getCluster({ name: "your-gke-cluster-name", location: "your-cluster-location", project: "your-gcp-project-id", }).then(cluster => cluster.kubeconfig), }); // Deploy the h2-database Helm chart. const h2DatabaseChart = new kubernetes.helm.v3.Chart("h2-database", { chart: "h2-database", // Specify the chart version you want to deploy. version: "desired-chart-version", // If the chart requires configuration values, specify them here. values: { // ... specify your values here. }, }, { provider: gkeK8sProvider }); // Export the public IP of the h2-database service for easy access. export const h2DatabaseServiceIp = h2DatabaseChart.getResourceProperty("v1/Service", "h2-database", "status") .then(status => status.loadBalancer.ingress[0].ip);

    What's happening in this program is straightforward:

    • It initializes a Pulumi Kubernetes provider that targets a specific GKE cluster. This provider is configured with the cluster's kubeconfig, which Pulumi retrieves using the gcp.container.getCluster function call. You'll need to replace "your-gke-cluster-name", "your-cluster-location", and "your-gcp-project-id" with your actual GKE cluster's name, location, and GCP project ID.

    • It then declares a Helm chart resource named h2-database using Pulumi's Kubernetes package. This resource represents the Helm chart that we want to deploy. The chart property signifies the name of the chart, and version is where you can specify which version of the chart you would like to install. If there are specific values that you need to provide to your Helm chart, such as custom configuration settings, these can be passed in using the values property.

    • Lastly, we're exporting the public IP address once the h2-database service is deployed, assuming that it is exposed externally via a LoadBalancer type of service. This makes the IP address easily retrievable after you run pulumi up.

    Please ensure that the Helm chart name h2-database and version desired-chart-version match what is available in the Helm repository you are using. If h2-database is not a chart in a public repository, you will need to add repo property within the Chart arguments that points to the custom Helm repository URL.

    Replace the placeholders as necessary to match your environment. After you run this Pulumi program with pulumi up, Pulumi will deploy the specified Helm chart to your existing GKE cluster.
