1. Deploy the kube-metrics-adapter helm chart on Rancher


    To deploy the kube-metrics-adapter Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we'll follow these steps:

    1. Set up the necessary Rancher 2.x provider and authenticate with your Rancher instance.
    2. Deploy the Helm chart to your Kubernetes cluster using the Pulumi resource Chart from the @pulumi/kubernetes package.

    Here's a step-by-step guide, along with the corresponding TypeScript program:

    Step 1: Set Up the Rancher 2.x Provider

    Install the Pulumi Rancher 2 package using npm:

    npm install @pulumi/rancher2

    Now authenticate with Rancher. Pulumi will respect the RANCHER_ACCESS_KEY, RANCHER_SECRET_KEY, and RANCHER_SERVER_URL environment variables to facilitate this. Ensure they are set in your environment before running your Pulumi program.

    Step 2: Install the Helm Chart

    Next, we will use the helm.Chart resource from the @pulumi/kubernetes package to deploy the kube-metrics-adapter Helm chart. This assumes that you have already set up your Pulumi program to communicate with a Kubernetes cluster managed by Rancher.

    If you haven't done so, install the Pulumi Kubernetes package using npm:

    npm install @pulumi/kubernetes

    You will also need to configure your Pulumi Kubernetes provider to communicate with the Kubernetes cluster. This usually involves setting up a kubeconfig file that Pulumi can use.

    Here's a simple program that demonstrates how to deploy the kube-metrics-adapter Helm chart:

    import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Initialize a Kubernetes provider using Rancher's kubeconfig obtained via the Rancher API or other means. const k8sProvider = new k8s.Provider("rancher-k8s", { kubeconfig: "<YOUR_KUBECONFIG_CONTENT>", }); // Deploy kube-metrics-adapter using the Helm Chart const kubeMetricsAdapterChart = new k8s.helm.v3.Chart("kube-metrics-adapter", { fetchOpts:{ repo: "https://github.com/zalando-incubator/kube-metrics-adapter", }, chart: "kube-metrics-adapter", // Specify the version of the chart you wish to deploy version: "1.1.0", // Values to pass to the helm chart, this would be where you can configure the chart. values: { // Replica count, image, resources, etc. would be configured here as needed. }, }, { provider: k8sProvider });

    The kubeMetricsAdapterChart instance creates a Helm release on your Rancher Kubernetes cluster. To specify the version of the Helm chart, you can replace 1.1.0 with the desired chart version.

    Remember to fill in <YOUR_KUBECONFIG_CONTENT> with the actual contents of your kubeconfig file or a path to the file. This tells the Kubernetes provider how to communicate with your Rancher-managed cluster.

    When you run this Pulumi program using the pulumi up command, it interacts with Rancher using the Rancher provider and deploys the kube-metrics-adapter Helm chart to your Kubernetes cluster.

    Make sure you have the Helm repository with the kube-metrics-adapter Helm chart. You may need to adjust the repo URL to the correct repository where the chart is hosted.

    Additional Information

    This should give you a solid starting point for deploying Helm charts on a Rancher-managed cluster with Pulumi.
