1. Deploy the csi-hcloud helm chart on Kubernetes


    Deploying the csi-hcloud Helm chart on Kubernetes using Pulumi can be accomplished using the Pulumi Kubernetes provider. The csi-hcloud chart is provided by Hetzner Cloud, and it deploys the Container Storage Interface (CSI) driver for Hetzner Cloud Volumes.

    The Pulumi Kubernetes provider allows us to deploy Helm charts with great ease. We will make use of the helm.v3.Chart resource, which represents a Helm chart in a Pulumi program.

    Below is a Pulumi TypeScript program that deploys the csi-hcloud Helm chart to a Kubernetes cluster. In this example, we assume that you have already configured your Kubernetes cluster and kubeconfig file so that Pulumi can communicate with your cluster.

    import * as k8s from "@pulumi/kubernetes"; // Create a new instance of the helm.v3.Chart class that represents the csi-hcloud helm chart. const csiHcloudChart = new k8s.helm.v3.Chart("csi-hcloud", { // Specify the chart name; this must correspond to the name of the chart in the repository. chart: "csi-hcloud", // Specify the repository where the csi-hcloud chart can be found. // You need to replace `<REPO_URL>` with the actual repository URL hosting the csi-hcloud chart. repo: "<REPO_URL>", // If required, you can customize the deployment by specifying values here. // For example, set the `createStorageClass` value to true to create a default storage class. values: { createStorageClass: true, }, // It is good practice to specify the version of the chart being used to avoid any unexpected changes. version: "1.2.3", // Replace with the desired chart version. }, { provider: k8sProvider }); // Ensure you set the correct Kubernetes provider if necessary. // Export the chart name. export const chartName = csiHcloudChart.metadata.name;


    • We import the @pulumi/kubernetes package, which contains helpers for working with Kubernetes resources in Pulumi programs.

    • We then create an instance of helm.v3.Chart. This is the class that represents a Helm chart deployment on Kubernetes through Pulumi.

    • The chart property specifies the name of the chart we want to deploy, in this case, csi-hcloud.

    • The repo property should point to the Helm repository where the csi-hcloud chart is hosted. You need to replace <REPO_URL> with the actual Helm repository URL.

    • The values property is a dictionary holding configuration values for the chart. These values overwrite default settings provided by the Helm chart with custom values. In this example, we set createStorageClass to true, which creates a default storage class for provisioning storage.

    • The version property specifies the version of the Helm chart that you want to deploy. It is essential to set this to avoid unexpected changes when the chart gets updated in the repository.

    • Finally, we export chartName, which helps us identify the deployed chart in later commands or outputs, and we set the Kubernetes provider if it is different from the default one.

    Note: Before running this Pulumi program, ensure you have:

    • Installed Pulumi CLI and set up the project with the correct settings for your Kubernetes cluster.
    • A pre-configured Kubernetes cluster that you have access to.
    • Access to the Helm repository containing the csi-hcloud chart, and you need to provide the correct URL to the repo property.
    • The desired version number of the Helm chart to deploy.

    If you meet all the requirements above, you can run this program using the Pulumi CLI commands:

    1. To create a new stack that represents a deployment environment (if you haven't yet):

      pulumi stack init dev
    2. To install dependencies from package.json:

      npm install
    3. To preview the deployment plan and see the resources that will be created:

      pulumi preview
    4. To execute the Pulumi program and deploy your chart to the cluster:

      pulumi up

    Follow the prompts by the CLI to complete the deployment.
