1. Deploy the zookeeper-3Nodes helm chart on Rancher


    To deploy the zookeeper-3Nodes Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we'll follow these steps:

    1. Ensure we have access to a Rancher-managed Kubernetes cluster.
    2. Use the Pulumi rancher2 package to interact with the Rancher API.
    3. Use the rancher2.AppV2 resource to deploy a Helm chart from a catalog.

    First, you need to have the Pulumi CLI installed and be authenticated with both Pulumi and Rancher. You should also have kubectl configured to interact with your Rancher cluster. Please refer to the Pulumi installation guide and the Rancher documentation for setup details.

    Next, we will write a Pulumi program in TypeScript to deploy the zookeeper-3Nodes Helm chart. Before running this Pulumi program, you need to have the Helm chart available in a Rancher catalog. If it's a public Helm chart, you might need to add the Helm chart repository to your Rancher catalogs through the Rancher UI or API.

    Here's the detailed Pulumi program that will perform the deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; const config = new pulumi.Config(); const rancherUrl = config.require("rancherUrl"); const tokenKey = config.requireSecret("tokenKey"); // Rancher provider configuration const rancherProvider = new rancher2.Provider("rancherProvider", { apiUrl: rancherUrl, tokenKey: tokenKey, }); // Reference an existing Rancher Cluster to deploy the chart const cluster = rancher2.getCluster({ name: "my-rancher-cluster", }, { provider: rancherProvider }); // Deploy zookeeper-3Nodes Helm chart using rancher2.AppV2 const zookeeperApp = new rancher2.AppV2("zookeeper-3nodes-app", { clusterId: cluster.id, // Ensure you specify the correct cluster ID namespace: "default", // Specify the namespace where to deploy repoName: "helm", // Make sure this repoName matches with your Rancher Catalog name chartName: "zookeeper-3Nodes", chartVersion: "x.y.z", // Replace x.y.z with the specific chart version you want to deploy values: ` replicaCount: 3 resources: requests: memory: "1Gi" cpu: "500m" # Define other values you need for your zookeeper-3Nodes chart `, }, { provider: rancherProvider }); // Export the name of the app export const zookeeperAppName = zookeeperApp.metadata[0].name;

    In this Pulumi program, you need to replace "my-rancher-cluster" with the name of your Rancher cluster. Additionally, specify the correct chartVersion of the zookeeper-3Nodes chart you want to deploy.

    When you run this Pulumi program using the Pulumi CLI, it will interact with your Rancher-managed Kubernetes cluster to deploy the Helm chart.

    Remember to save the above code in a file with a .ts extension, such as index.ts, and run pulumi up to deploy your resources. Make sure you have the required NodeJS dependencies installed, including @pulumi/pulumi and @pulumi/rancher2.

    For more details and options for configuring the AppV2 resource or the rancher2 provider, you can refer to the official Pulumi documentation for rancher2.AppV2 and rancher2.Provider.

    Please note that you will need to have the necessary permissions and authentication configured for the Pulumi rancher2 Provider to interact with your Rancher instance-API. This often involves generating API tokens within Rancher that are then supplied to Pulumi, as demonstrated in the program above.
