1. Deploy the ccm-hetzner helm chart on Rancher


    Deploying a Helm chart on Rancher using Pulumi involves several steps. First, you need to have a Kubernetes cluster managed by Rancher, then you'll have to access Rancher's management capabilities, usually through its API, and finally use those capabilities to deploy a Helm chart.

    Since you've specified the use of the ccm-hetzner Helm chart, which is a Cloud Controller Manager for Hetzner Cloud, you'll need a Kubernetes cluster running in Hetzner Cloud that is managed by a Rancher instance.

    Below, you'll find a Pulumi TypeScript program that outlines the steps to deploy the ccm-hetzner Helm chart on a Rancher-managed Kubernetes cluster. The program assumes that you have already set up a Kubernetes cluster and a Rancher server that can manage it.

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Configure Rancher 2 provider // The Rancher 2 provider needs to be configured with the access credentials to communicate with your Rancher server. // This typically includes the Rancher API URL and an API token. const rancher2Provider = new rancher2.Provider("rancher", { apiUrl: "https://your-rancher-api-url.com/v3", tokenKey: "your-rancher-api-token", }); // Step 2: Access the Kubernetes cluster managed by Rancher // You'll need to reference the cluster in Rancher where you want to deploy the Helm chart. // For this example, we simply inquire the cluster by its ID using the rancher2.Cluster.get method. const cluster = rancher2.Cluster.get("my-cluster", "cluster-id", undefined, { provider: rancher2Provider}); // Step 3: Create a Kubernetes provider for the targeted cluster // Using the retrieved cluster information, we initialize a Kubernetes provider which allows Pulumi // to deploy resources to that specific cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfig, }); // Step 4: Deploy the ccm-hetzner Helm chart // Now that we have an appropriate Kubernetes provider for our target cluster, we can deploy // the ccm-hetzner Helm chart into it. This chart installs and configures the Hetzner Cloud Controller Manager // which is used to integrate Kubernetes with the Hetzner Cloud for node and load balancer management. const ccmHetzner = new k8s.helm.v3.Chart("ccm-hetzner-chart", { chart: "ccm-hetzner", namespace: "kube-system", // Typically, cloud controller managers are deployed in the kube-system namespace // The values here depend on the Helm chart and any specific configurations you need for your cloud controller. values: { hetzner: { // Refer to the ccm-hetzner's values.yaml file or the corresponding documentation to know the available options // and provide the necessary configuration here. For example, you need to provide an API token if required. apiToken: "your-hetzner-api-token", // ... any other custom configurations }, }, }, { provider: k8sProvider }); // Step 5: Export the name of the chart export const chartName = ccmHetzner.metadata.name;

    Make sure you replace your-rancher-api-url.com/v3, your-rancher-api-token, cluster-id, and your-hetzner-api-token with actual values from your Rancher setup and your Hetzner Cloud account.

    Here's what the program does:

    1. Configure Rancher 2 Provider: Establishes the connection with your Rancher instance by creating a Provider resource with the URL and token for the API.

    2. Access the Kubernetes Cluster Managed by Rancher: Retrieves the information about your cluster managed by Rancher. In this example, this is done via the rancher2.Cluster.get method.

    3. Create a Kubernetes Provider: Sets up a Kubernetes provider that is configured to interact with your Rancher-managed cluster.

    4. Deploy the ccm-hetzner Helm Chart: Utilizes the Kubernetes provider to deploy the specified Helm chart within your cluster in the kube-system namespace.

    5. Export Chart Name: As a final step, the program exports the name of the Helm chart for reference.

    Please note that Helm charts often require configuration through values, which are specific to the chart and the environment in which you're deploying. You'll need to refer to the ccm-hetzner chart's documentation to determine what values make sense in your case.

    This Pulumi program is a description of our desired state, Pulumi will handle the rest, making sure that the described resources are created and configured as specified.
