1. Deploy the kube-admission-controller-starter helm chart on Rancher


    Deploying a Helm chart on a Kubernetes cluster managed by Rancher can typically involve a few steps:

    1. Import or create a Kubernetes cluster in Rancher.
    2. Install and configure the Helm CLI to work with the cluster.
    3. Deploy the Helm chart to the cluster.

    In the context of using Pulumi to automate this process, you would need to define the infrastructure as code using Pulumi's programming model. However, based on the Pulumi Registry Results provided, there is no direct representation of Helm resources for Rancher. Instead, we can leverage the Kubernetes provider from Pulumi to deploy Helm charts to a Kubernetes cluster that is managed by Rancher.

    Here, I will provide you with a program that uses Pulumi's kubernetes package to deploy the kube-admission-controller-starter Helm chart to a Kubernetes cluster. Note that this assumes you have a Kubernetes cluster already set up and managed by Rancher, and that you have configured your kubeconfig file to point to this cluster. You must also have Helm installed on your local machine or in your environment.

    The following program is written in TypeScript:

    import * as k8s from "@pulumi/kubernetes"; // Create a new Kubernetes provider instance that uses the kubeconfig from your environment. const provider = new k8s.Provider("k8s", { kubeconfig: process.env.KUBECONFIG, }); // Define the release for the kube-admission-controller-starter Helm chart. const kubeAdmissionControllerRelease = new k8s.helm.v3.Release("kube-admission-controller-starter", { chart: "kube-admission-controller-starter", // Replace with the actual repository where the chart is located, if different. repositoryOpts: { repo: "https://charts.yourchartrepo.com/", }, // Define values for the Helm chart as needed. values: { // ... any chart specific values }, }, { provider }); // Export the name of the chart deployment export const chartName = kubeAdmissionControllerRelease.name;

    Here's a breakdown of what the code is doing:

    1. The @pulumi/kubernetes package is imported to use the Kubernetes provider.
    2. A new Kubernetes provider instance is created with kubeconfig from your environment (you should ensure the KUBECONFIG environment variable is set with the path to your kubeconfig file).
    3. The kubeAdmissionControllerRelease is a Pulumi resource that represents the deployment of the Helm chart. You need to specify the:
      • Name of the Helm chart (kube-admission-controller-starter).
      • Repository where the Helm chart is located.
      • Any values specific to the chart that you would like to override.
    4. Lastly, the deployment name is exported so you can easily identify the Helm release in your cluster.

    Make sure you have Pulumi installed and configured to use with your cloud provider. Also, make sure Helm CLI is installed and that your kubeconfig file is correctly set up to communicate with your Kubernetes cluster managed by Rancher.

    With this program, running pulumi up will attempt to deploy the kube-admission-controller-starter Helm chart to your Kubernetes cluster. Make sure to replace the placeholder for the chart repository with the actual repository's URL where the chart is hosted. Also, include any values you want to customize within the values property.
