1. Deploy the kamaji-etcd helm chart on Rancher


    Deploying a Helm chart on Rancher using Pulumi involves several steps. First, you need to ensure that you have a Kubernetes cluster managed by Rancher and then deploy the desired Helm chart to that cluster. Pulumi provides resource types through its various providers for managing both Rancher and Kubernetes resources.

    Below is a TypeScript program that uses Pulumi to deploy a Helm chart on a Kubernetes cluster managed by Rancher. The program will first set up a Rancher cluster (if you don't already have one) and then use the helm.v3.Chart resource from the @pulumi/kubernetes package to deploy the kamaji-etcd Helm chart.

    This program assumes that you have set up the Pulumi CLI, authorized access to your Rancher instance, and configured your local environment to manage your Kubernetes cluster through Pulumi.

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Step 1: Set up a Rancher2 Cluster (this is an example, make sure to replace the values to fit your setup) const rancherCluster = new rancher2.Cluster("my-rancher-cluster", { // Add required configuration parameters according to Rancher cluster documentation // Refer to: https://www.pulumi.com/registry/packages/rancher2/api-docs/cluster/ }); // Step 2: Obtain a k8s provider for the above cluster const k8sProvider = new kubernetes.Provider("my-k8s-provider", { kubeconfig: rancherCluster.kubeConfig, // assuming `kubeConfig` is an output from the `rancher2.Cluster` resource }); // Step 3: Deploy the kamaji-etcd Helm chart using helm.v3.Chart from the Pulumi Kubernetes provider const kamajiEtcdChart = new kubernetes.helm.v3.Chart("kamaji-etcd", { // Replace with the actual chart values chart: "kamaji-etcd", version: "YOUR_CHART_VERSION", // Replace with the version of kamaji-etcd Helm chart fetchOpts: { repo: "REPO_URL", // Replace with the repository URL where the helm chart is hosted }, }, { provider: k8sProvider }); // Ensure it uses the k8s provider that we created pointing to Rancher // Export any pertinent resource outputs export const chartName = kamajiEtcdChart.metadata.name;

    This program consists of the following parts:

    1. Rancher2 Cluster Setup: This section initializes a new Rancher cluster configuration. You need to replace placeholder values with your specific cluster parameters as per your Rancher setup.

    2. Kubernetes Provider Setup: This part creates a Pulumi Kubernetes provider configured to interact with the Kubernetes cluster created by Rancher.

    3. Helm Chart Deployment: In this step, you declare a new helm.v3.Chart which is the core Pulumi resource to deploy Helm charts. It requires specifying the chart name, version, and repository URL.

    Remember that this program only illustrates a generic deployment; specific details like chart version, repository URL, and other Helm chart configurations must be provided to match the kamaji-etcd chart's requirements.

    After defining your Pulumi program, you typically run it using the following steps:

    • Install Pulumi CLI and login to your backend (if not already done).
    • Ensure you have access to your Rancher instance and have configured any necessary credentials.
    • Run pulumi up via the command line to preview and deploy your resources.

    Keep in mind that this example assumes you have a cluster managed by Rancher. If you have an existing cluster or different configuration parameters, you'll need to adjust the program accordingly. Always refer to the official Pulumi documentation for the Rancher2 provider for all configurable options and definitions.
