1. Deploy the rke2-canal helm chart on Kubernetes

    TypeScript

    To deploy an RKE2 Canal Helm chart on a Kubernetes cluster using Pulumi, you will write a program in TypeScript that leverages the Pulumi Kubernetes provider. This program will create a Helm chart resource referencing the RKE2 Canal Helm chart within a specified namespace on your Kubernetes cluster.

    Here's the breakdown of the steps we'll follow in the Pulumi program:

    1. Import required Pulumi and Kubernetes packages.
    2. Create an instance of Chart which Pulumi will use to apply the RKE2 Canal Helm chart to the Kubernetes cluster.
    3. Set the chart name to rke2-canal and provide the necessary configuration, such as the version of the Helm chart and any custom values you wish to specify.
    4. Export any necessary stack outputs, such as the status of the deployed Helm chart.

    Now, let's proceed with the Pulumi TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // Create a Kubernetes provider instance. The provider uses the kubeconfig file to connect to a Kubernetes cluster. const provider = new kubernetes.Provider("k8s-provider", { // If you have multiple kubeconfig files, specify the appropriate one here using `kubeconfig` field. }); // Deploy the RKE2 Canal Helm chart in the 'default' namespace // Replace `<version>` with the desired chart version. const rke2CanalChart = new kubernetes.helm.v3.Chart("rke2-canal", { chart: "rke2-canal", version: "<version>", // specify the chart version here namespace: "default", // modify if you want to deploy in a different namespace // If you need to pass any specific values to the Helm chart, define them here in the `values` field. }, { provider }); // (Optional) Export the status of the deployed Helm chart export const helmChartStatus = rke2CanalChart.status;

    In this program:

    • We begin by importing the necessary Pulumi and Kubernetes JavaScript packages to interact with the Kubernetes API.
    • We create a Pulumi Kubernetes provider that serves as the bridge between the Pulumi program and the targeted Kubernetes cluster. The provider configuration would usually default to using the local kubeconfig file for authentication, but you can specify another file if necessary.
    • We define a Chart resource provided by the Pulumi Kubernetes Helm Chart package to deploy the RKE2 Canal Helm chart onto our cluster. You'll need to specify the chart's version that you want to deploy. Helm charts are typically hosted in chart repositories, and you can also provide the chart's repository in the configuration if it's not in the default Helm repository.
    • Optionally, we export an output variable to observe the status of the deployed Helm chart, which can provide insights into the deployment's result.

    Remember to replace the <version> placeholder with the correct version number of the RKE2 Canal Helm chart you intend to deploy. You can look up the chart version from the rancher/charts GitHub repository or directly from the Helm repository where the chart is hosted.

    To run this Pulumi program, save the code to a index.ts file and use the Pulumi CLI to create a new stack and update your cloud infrastructure:

    pulumi stack init dev pulumi up

    The pulumi up command will compile the TypeScript program to JavaScript, prompt you for a preview of the operations it will perform, and upon confirmation, will proceed to deploy the Helm chart to your Kubernetes cluster.

    For further details on Helm chart usage with Pulumi, you may refer to the Pulumi API Documentation for Helm charts.
