1. Deploy the flink-kubernetes-operator helm chart on Kubernetes


    To deploy the Flink Kubernetes Operator using a Helm chart with Pulumi, we'll leverage the Helm Chart resource from the kubernetes provider. The resource enables us to deploy a chart from a specified repository, manage configurations, and control the versioning of the chart, entirely through code. The Flink Kubernetes Operator chart will help manage Flink applications on a Kubernetes cluster.

    Below is a step-by-step Pulumi TypeScript program that performs the following actions:

    1. Imports the necessary Pulumi and Kubernetes packages.
    2. Specifies the chart repository and name, and version of the Flink Kubernetes Operator Helm chart.
    3. Utilizes the Chart resource from the @pulumi/kubernetes/helm/v3 package to deploy the chart onto the Kubernetes cluster.
    4. Sets any additional configurations, if needed, via the values property.

    Before you run the Pulumi program, ensure:

    • Pulumi CLI is installed and logged in to the desired account and workspace.
    • Kubernetes cluster is up and running and kubectl is configured to connect to it.
    • Access to the Helm chart repository for Flink Kubernetes Operator is available.

    Here's a Pulumi program that accomplishes the deployment:

    import * as k8s from '@pulumi/kubernetes'; // Define the Helm chart version and the repository URL const flinkOperatorChartVersion = 'x.y.z'; // Replace with a specific chart version const flinkOperatorChartRepo = 'https://flink-operator-repo/flink-helm-chart'; // Replace with the Flink operator's Helm chart repository URL // Deploy the Flink Kubernetes Operator using Helm const flinkOperatorChart = new k8s.helm.v3.Chart('flink-kubernetes-operator', { chart: 'flink-kubernetes-operator', version: flinkOperatorChartVersion, fetchOpts: { repo: flinkOperatorChartRepo, } // If you have custom values you'd like to set, you can define them here // For instance: // values: { // key: value, // } }); // Export the resources deployed export const flinkOperator = flinkOperatorChart.resources;

    In this code:

    • We import the Kubernetes package from Pulumi.
    • We specify the Helm chart's name (flink-kubernetes-operator), the version we want to deploy (replace x.y.z with the actual chart version), and the repository where the chart is located (replace https://flink-operator-repo/flink-helm-chart with the actual URL).
    • The Chart resource in Pulumi corresponds to a Helm chart. It's a high-level abstraction that allows deploying applications defined by a Helm chart. Here, we use it to deploy the Flink Kubernetes Operator.
    • Replace key: value with actual values you might want to set for your deployment. These values would typically be documented by the Helm chart and allow you to customize the installation.
    • Lastly, we export the list of resources created by the Helm chart for easy access to their details (like deployed service names, URLs, etc.).

    To run this Pulumi program, you need to save it in a file named index.ts, initialize a Pulumi project with pulumi new, install the npm dependencies (the @pulumi/kubernetes package, in this case), and finally run pulumi up to execute the deployment.
