1. Deploy the openunison-k8s-cluster-management-by-group helm chart on Rancher


    To deploy the openunison-k8s-cluster-management-by-group Helm chart on a Kubernetes cluster managed by Rancher using Pulumi, we will follow these steps:

    1. Setting up a Rancher Cluster: We will create or use an existing Rancher-managed Kubernetes cluster in which we will deploy our Helm chart.

    2. Installing Helm: Helm is a package manager for Kubernetes that allows us to easily deploy and manage applications. We'll be using the Helm Pulumi library for this purpose.

    3. Deploying the Helm Chart: We will describe how to deploy the openunison-k8s-cluster-management-by-group chart into our cluster.

    Here is a basic TypeScript program that uses Pulumi to perform these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Please ensure your Pulumi configuration is correctly set up for the Rancher provider. // Step 1: Setting up a Rancher Cluster // This code assumes the Rancher cluster is already set up and we are just going to obtain a reference to it. // If you need to create a new cluster, you can use the rancher2.Cluster resource. // Replace 'my-rancher-cluster' with the actual Rancher Cluster ID const cluster = rancher2.getCluster({ name: "my-rancher-cluster" }); // Step 2: Installing Helm // We don't have to install Helm separately as Pulumi handles that for us behind the scenes. // Instead, we just need to instantiate the Helm chart resource. // Step 3: Deploying the Helm Chart // Replace 'NAMESPACE' with the actual Kubernetes namespace where you want to deploy the chart. // If the namespace does not exist, you can create it using the k8s.core.v1.Namespace resource. const openunisonChart = new k8s.helm.v3.Chart("openunison-k8s-cluster-management-by-group", { chart: "openunison-k8s-cluster-management-by-group", version: "CHART_VERSION", // Specify the chart version you wish to deploy namespace: "NAMESPACE", // Replace with the target namespace }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfig }) }); // We use the Rancher2 provider to get the kubeconfig of our cluster, // which is then fed to the Kubernetes provider to manage the resources in that cluster. // The Helm chart is deployed within the specified namespace on the Kubernetes cluster managed by Rancher. export const openunisonChartName = openunisonChart.metadata.name;


    • Rancher Cluster: The above program assumes that you already have a Rancher-managed Kubernetes cluster. The rancher2.getCluster function is used to retrieve the existing cluster details from Rancher. If you need to create a new Rancher-managed cluster, you must use the rancher2.Cluster resource. Please replace my-rancher-cluster with your actual cluster ID.

    • Helm: Pulumi's Kubernetes provider understands Helm and abstracts away the need to manually install Helm. Instead, we use the k8s.helm.v3.Chart class to declare our Helm chart.

    • The openunison-k8s-cluster-management-by-group Helm Chart: You will need to know the version of the chart you want to install and the Kubernetes namespace where it should be installed. Replace CHART_VERSION with the correct chart version, and NAMESPACE with the target namespace where the chart will be deployed.

    • Providers: Pulumi providers allow us to interact with different cloud services. In this case, we are using both the Rancher and Kubernetes providers. The Kubernetes provider needs a kubeconfig file to interact with the Kubernetes cluster, which we obtain from our Rancher cluster using the Rancher2 provider.

    After setting up this program, you run it using the Pulumi command-line interface (CLI) to perform the deployment. Make sure to install the required Pulumi packages by running npm install or yarn add.
