1. Deploy the cluster-api-provider-hetzner helm chart on Kubernetes


    To deploy the cluster-api-provider-hetzner Helm chart on a Kubernetes cluster using Pulumi, you will first need to set up a Kubernetes cluster. Once the cluster is ready, you can use Pulumi's Kubernetes provider to deploy Helm charts.

    Pulumi allows you to declare infrastructure as code using programming languages. In this case, we'll use TypeScript, which is a strongly-typed language that builds on JavaScript giving you better tooling at any scale.

    We'll be using the @pulumi/kubernetes package to interact with Kubernetes, and specifically the Chart resource to deploy a Helm chart. The Chart resource is a high-level abstraction that deploys a Helm chart from a repository.

    Here's the program that deploys the cluster-api-provider-hetzner Helm chart on Kubernetes:

    import * as k8s from '@pulumi/kubernetes'; // The name of the Helm chart const chartName = "cluster-api-provider-hetzner"; // The repository where the Helm chart is located const chartRepo = "https://registry.pulumi.com/"; // Define the Helm chart version const chartVersion = "0.3.4"; // Replace with the desired chart version // Create a Kubernetes Provider instance. // This should point to the intended Kubernetes cluster. // This assumes that you've already configured kubectl to point to your Kubernetes cluster. const provider = new k8s.Provider("k8s-provider", { kubeconfig: "<your-kubeconfig>", // You can manually specify your kubeconfig or omit if it's already configured through the environment. }); // Deploy the cluster-api-provider-hetzner Helm chart to the Kubernetes cluster. const hetznerChart = new k8s.helm.v3.Chart(chartName, { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo }, // If you need to specify any custom values for the chart, // provide them here. For example: // values: { // key1: value1, // key2: value2, // ... // }, }, { provider: provider }); // Export the Helm chart name and version export const deployedChartName = hetznerChart.chart; export const deployedChartVersion = hetznerChart.version;

    Here's a breakdown of what the above program does:

    • We import the necessary modules from the Pulumi Kubernetes package.
    • We define constants for the chart name, chart repository, and chart version. You need to use the actual version of the chart you intend to deploy.
    • We create a Kubernetes provider instance pointing to our intended Kubernetes cluster. This utilizes kubeconfig which is a configuration file for accessing the Kubernetes API. Typically, this is set up when you create your Kubernetes cluster, and your local kubectl would be configured to interact with this cluster.
    • We instantiate a new Chart which is Pulumi's representation of a Helm chart. In the options passed to the Chart constructor, we specify the repo for the Helm chart as well as any custom values that you might want to override in the Helm chart. You can adjust the values dictionary to include any configuration overrides required for your specific setup.
    • We export the name and version of the deployed chart as stack outputs, which can be used to verify the deployment.

    Remember to replace <your-kubeconfig> with your actual Kubernetes configuration file contents if you're not using the default location that kubectl automatically detects. If you're running this in an environment where it's already set (like a CI/CD pipeline), you can omit the kubeconfig to use the ambient configuration.

    To run this code, you need to save it in a .ts file and use Pulumi CLI to deploy it. Make sure you have installed Pulumi and configured it with the cloud provider credentials you need. Then run pulumi up to deploy your infrastructure. If you're new to Pulumi, check out the Pulumi's Getting Started guide for more details.
