1. Deploy the provider-hcloud helm chart on Rancher


    To deploy a Helm chart on Rancher using the provider-hcloud (Hetzner Cloud), you will have to interact with Rancher's Kubernetes-based environment through Pulumi's rancher2 provider. The rancher2 provider allows for managing resources in a Rancher v2.x installation.

    Here's a general walkthrough of the steps you’d follow to accomplish this, along with a Pulumi program in TypeScript to demonstrate how you can implement it:

    1. Set up the Pulumi toolchain: Ensure you have Pulumi CLI installed and set up with the required cloud credentials.
    2. Install Node.js and Pulumi's TypeScript SDK: If you haven't already, install Node.js and use npm to install the @pulumi/pulumi package.
    3. Set up Rancher2 Provider: To work with Rancher2's resources, you'll need to set up the rancher2 provider. The provider needs access to Rancher's API, which can be configured using the access key and secret key.
    4. Create a Kubernetes Cluster: Use the Cluster resource to create a Kubernetes cluster in Rancher.
    5. Deploy Helm Chart: Deploy the provider-hcloud Helm chart to the cluster. This is generally done using Kubernetes' helm.v3.Chart resource, but since we're working within a Rancher-managed cluster, you’d use Rancher's App resource.

    Below is a Pulumi program in TypeScript that outlines these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Note: Configure your Pulumi program with Rancher access credentials. // This could be done via the `config` system in Pulumi, environment variables, or directly in code. // Initialize a Rancher2 provider instance with credentials to communicate with the Rancher instance const rancherProvider = new rancher2.Provider("rancherProvider", { // Set your Rancher API endpoint and access credentials here apiURL: "https://your-rancher-api-endpoint", accessKey: "your-rancher-access-key", secretKey: "your-rancher-secret-key", }); // Create a Kubernetes cluster in Rancher that you will deploy the provider-hcloud Helm chart to. // Here you would specify the details such as node count, cluster version, and other cloud-specific settings. const cluster = new rancher2.Cluster("hcloud-cluster", { // Specify the cluster configuration according to Hetzner Cloud's required parameters // and any specifics for your setup. name: "hcloud-cluster", // You need to specify the driver details specific to Hetzner Cloud rkeConfig: { // Your RKE config specific to the Hetzner Cloud goes here }, // Additional configurations and details can go here }, { provider: rancherProvider }); // Once your cluster is ready, you can deploy the provider-hcloud Helm chart. // For a Helm chart deployment, Rancher uses its catalog Apps feature. // Specify the Helm chart details, repository, and corresponding values for the chart. const hcloudApp = new rancher2.App("hcloud-helm-app", { // Set reference to the created cluster ID clusterId: cluster.id, // Set target namespace for the Helm chart within the Kubernetes cluster namespaceId: "namespace-id", // replace with actual namespace_id // Provide the details for the chart you want to install catalogName: "catalog-name", // replace with the catalog name which lists provider-hcloud chartName: "provider-hcloud", // exact chart name for Hetzner Cloud integration valuesYaml: `# Your values file in YAML format`, // Configuration for your hcloud provider chart // Other configurations such as target version, etc. go here }, { provider: rancherProvider, dependsOn: [cluster] }); // Export any necessary fields that you might need to access export const clusterName = cluster.name; export const appName = hcloudApp.name;

    The code comments within the Pulumi program provide guidance on the configuration and steps required to create the cluster and deploy a Helm chart in Rancher.

    Before running this code, make sure to replace placeholders such as https://your-rancher-api-endpoint, your-rancher-access-key, and other specifics with actual values from your Hetzner Cloud and Rancher setup. Also, adjust any resource properties to match those of your cloud provider’s specifications.

    To execute the Pulumi code, navigate to the directory with the Pulumi.yaml and TypeScript files, then run pulumi up. This command will start the deployment process as described by your Pulumi code above.

    Remember, deploying cloud resources requires appropriate permissions and may incur costs according to your cloud provider's pricing. Always review the execution plan, which Pulumi presents before the actual deployment, and ensure all configurations are correct and within your budget.
