1. Deploy the ca-clusterissuer helm chart on Rancher


    To deploy the ca-clusterissuer Helm chart on a Rancher-managed Kubernetes cluster, you'll use Pulumi's Rancher 2 provider to interact with your Rancher instance. This provider allows you to define and manage resources in your Rancher environment using infrastructure as code.

    First, you will need to install the @pulumi/rancher2 package to make use of the Rancher 2 provider in your Pulumi program. You can do this by running the following command in your project directory:

    npm install @pulumi/rancher2

    Once you have installed the required package, you can write a Pulumi program in TypeScript to deploy the ca-clusterissuer Helm chart. We'll proceed with the following assumptions:

    1. You have already configured the Pulumi Rancher 2 provider with the necessary credentials to communicate with your Rancher API.
    2. You know the name of the Rancher-managed Kubernetes cluster where you will deploy the Helm chart.
    3. You have the ca-clusterissuer Helm chart available in a chart repository or local directory.

    In the program below, you will see how to deploy a Helm chart to your Rancher cluster. You need to replace the placeholder values with actual information corresponding to your Rancher configuration and the ca-clusterissuer Helm chart details.

    We'll use the rancher2.App resource to deploy the Helm chart. This resource is responsible for applications in Rancher which correspond to Helm charts that can be deployed to Kubernetes clusters managed by Rancher.

    Here's the program that demonstrates how to achieve this:

    import * as pulumi from "@pulumi/pulumi"; import * as rancher2 from "@pulumi/rancher2"; // Define your cluster where the Helm chart will be deployed. // Replace 'your-cluster-id' with the actual id of your Rancher-managed Kubernetes cluster. const clusterId = 'your-cluster-id'; // Create an instance of the App resource to deploy the ca-clusterissuer Helm chart. const caClusterIssuer = new rancher2.App("ca-cluster-issuer", { // Provide the cluster ID where the app will be installed clusterId: clusterId, // The namespace where the `ca-clusterissuer` Helm chart will be deployed // Replace this with the desired namespace if it needs to be specific namespaceId: "default", // Name of the Helm chart to deploy // If it's from a chart repository or Rancher's library, provide // the chart name and repository URL. Otherwise, for a local chart, // provide the path to the chart directory targetNamespace: "cert-manager", projectId: "<project-id>", // Specify the Rancher Project ID externalId: "catalog://?<catalog-name>/<chart-name>:<version>", // For example, for a Helm chart available at a URL: // catalog://?catalog=helm&template=ca-clusterissuer&version=1.0.0 // Chart values can be provided here. These values correspond to the // settings that can be customized for the Helm chart. The format is // equivalent to the values.yaml file from Helm. values: `{ "service": { "type": "ClusterIP" }, "replicaCount": 1 }` // You can provide additional options here such as setString, setFile, etc. // These are used to customize chart values in different ways // setString: [{'name':'service.type','value':'ClusterIP'}], }); // To retrieve info like the app's name export const appName = caClusterIssuer.name;

    In the above program, replace the dummy values (your-cluster-id, <chart-name>, <version>, etc.) with actual values corresponding to your setup. The externalId property is how you reference the chart in Rancher. If the chart is part of the built-in library, it needs to include the catalog as well. If your chart has a custom values.yaml, you would convert the contents to a JSON string and pass them to the values field.

    After writing your Pulumi program, you can deploy it by running the following commands:

    pulumi stack init dev # Initializes a new stack called 'dev' pulumi up # Deploys your Pulumi program to Rancher

    These commands initiate a Pulumi stack, which represents an isolated environment for your app's resources, and then deploy those resources as specified in your Pulumi program.

    If you are new to Pulumi or the concept of infrastructure as code, I recommend exploring the Pulumi documentation to get familiar with the core concepts, and specifics around configuration, running updates, and managing stacks.
