1. Deploy the rook-operator helm chart on Kubernetes


    To deploy the rook-operator Helm chart on Kubernetes using Pulumi, you'd typically leverage the @pulumi/kubernetes library. This library provides a way to declare Kubernetes resources, including Helm charts, using TypeScript. Here, we will use the Chart resource, which represents a Helm chart.

    Before we get started with the code, make sure you have the following prerequisites completed:

    • Pulumi CLI installed and set up with an appropriate backend.
    • Kubernetes cluster configured and the kubeconfig file is correctly set up on your machine.
    • Helm chart information for rook-operator is known, such as the chart name and the repository it resides in.

    Below is a Pulumi program in TypeScript that deploys the rook-operator Helm chart to a Kubernetes cluster.

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes namespace for Rook Operator if you want to isolate it. const rookNamespace = new k8s.core.v1.Namespace("rook-ns", { metadata: { // You can add additional metadata if needed name: "rook-operator", }, }); // Deploy the Rook Operator Helm chart in the Kubernetes cluster. const rookOperatorChart = new k8s.helm.v3.Chart("rook-operator-chart", { chart: "rook-ceph", version: "v1.5.9", // Use the correct chart version namespace: rookNamespace.metadata.name, // Deploy to the created namespace // Specify the Helm repository that contains the Rook Operator chart fetchOpts: { repo: "https://charts.rook.io/release", }, // If you need to provide custom values to the chart, you can specify them here. // Otherwise, you can omit the 'values' field to use the defaults. values: { // Replace with the necessary chart values }, }); // Export the Namespace name and the Chart name export const namespaceName = rookNamespace.metadata.name; export const chartName = rookOperatorChart.metadata.name;

    Here is what's happening in the program:

    • We start by importing the Pulumi Kubernetes SDK.
    • We create a new Kubernetes Namespace resource called rook-ns. Namespaces are a way to divide cluster resources between multiple users.
    • We define a Chart resource to deploy the rook-operator chart from the specified Helm chart repository. Replace v1.5.9 with the correct version of the rook-operator chart you wish to deploy.
    • You can also specify configuration options according to your needs inside the values object. For instance, you can customize storage options and versions.
    • We export the namespace and chart names to use them easily with Pulumi CLI or in automated CI/CD pipelines.

    To apply this Pulumi program, save it to a file named index.ts, and run the following commands in the same directory as the file:

    pulumi up

    This command will prompt you with a summary of the deployment plan. Confirm the plan to proceed with the deployment to your Kubernetes cluster. Pulumi will use your local kubeconfig to communicate with your Kubernetes cluster and deploy the Helm chart.

    Pulumi provides a declarative approach to manage cloud resources, which includes managing Kubernetes resources through code, allowing easy tracking of resource changes in version control, systematic deployments, and repeatability across environments.
