1. Deploy the flink-kubernetes-operator helm chart on Google Kubernetes Engine (GKE)


    Deploying the flink-kubernetes-operator Helm chart on Google Kubernetes Engine (GKE) involves several steps. Before you begin, you need to have Pulumi installed, an account on Google Cloud Platform, and you should have gcloud configured to authenticate with your Google Cloud account.

    Here's an overview of the steps you'll take in this Pulumi program:

    1. Create a new GKE cluster or use an existing one.
    2. Configure Kubernetes provider to connect to the created GKE cluster.
    3. Deploy the flink-kubernetes-operator chart using Pulumi's helm.v3.Chart resource.

    We'll start by importing necessary Pulumi libraries and initializing the GKE cluster. Then, we'll proceed to set up the Helm chart deployment.

    The following TypeScript program demonstrates how to accomplish the goal:

    import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a new GKE cluster const cluster = new gcp.container.Cluster("flink-operator-cluster", { initialNodeCount: 2, minMasterVersion: "latest", // Use the latest version of GKE nodeVersion: "latest", nodeConfig: { machineType: "e2-standard-4", oauthScopes: [ // Set the minimum required scopes "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" ], }, }); // Step 2: Configure the Kubernetes provider to connect to the GKE cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), // Extract kubeconfig from created GKE cluster }); // Step 3: Deploy the flink-kubernetes-operator helm chart const flinkOperatorChart = new k8s.helm.v3.Chart("flink-operator-chart", { chart: "flink-kubernetes-operator", // Ensure that the chart name is correct fetchOpts: { repo: "https://<repository-url>", // Replace with the Helm repository URL that hosts the flink-kubernetes-operator chart }, version: "0.1.0", // Specify the chart version you wish to deploy // Include any necessary Helm values here // values: { // image: { // repository: "<image-repo>", // tag: "<tag>", // }, // ... // }, }, { provider: k8sProvider }); // Export the Cluster name and kubeconfig export const clusterName = cluster.name; export const kubeConfig = cluster.kubeconfig;

    In this program:

    • We create a new GKE cluster with two nodes and use the latest version for both the master and nodes. The machine type e2-standard-4 is selected for the nodes, which is a balance between performance and cost. You can adjust these values based on your workload requirements.

    • We obtain the kubeconfig from the created GKE cluster which is needed to communicate with the Kubernetes cluster.

    • We then proceed to deploy the flink-kubernetes-operator Helm chart using Pulumi's k8s.helm.v3.Chart class. Note that you will need to replace <repository-url> with the actual Helm repository URL where the flink-kubernetes-operator chart is hosted, and you may also need to specify the chart version and image values.

    The final step exports the GKE cluster name and kubeconfig, which you can use to interact with your Kubernetes cluster using kubectl or other Kubernetes tools.

    Keep in mind that when providing values that are sensitive (like passwords or private keys), you should use Pulumi secrets to encrypt those values.

    After writing this code in a TypeScript file (e.g., index.ts), you can deploy the resources by running the following commands:

    pulumi stack init dev pulumi up

    This will prompt you for confirmation before provisioning the resources on GCP. Make sure your Pulumi CLI is logged in and configured with the correct cloud provider credentials before you execute the commands.
