1. Deploy the terraform-cloud helm chart on Rancher


    To deploy the Terraform Cloud Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we can take the following approach:

    1. Helm Chart: The Helm chart we’re interested in is the Terraform Cloud. Helm charts define a package of pre-configured Kubernetes resources.

    2. Rancher: Rancher is an open-source multi-cluster management platform that allows managing Kubernetes clusters across different cloud providers from a single pane of glass.

    3. Pulumi with Rancher: Pulumi offers a Rancher2 provider which can manage resources in Rancher 2.x, including deploying Helm charts on Kubernetes clusters managed by Rancher.

    To get started with deploying a Helm chart to Rancher using Pulumi, you first need a Rancher cluster set up and accessible. You are also expected to have a Pulumi project with the required configuration to communicate with your Rancher setup.

    Here's an overview program, articulated in TypeScript, illustrating how to deploy the Terraform Cloud Helm chart on a Rancher-managed Kubernetes cluster.

    First, ensure you have Pulumi installed and configured for TypeScript, and then follow these steps:

    1. Initialize a new Pulumi project if you haven't already.
    2. Install the necessary Pulumi providers, which for Rancher would be @pulumi/rancher2.
    3. Write the Pulumi code that describes the desired state of your infrastructure.

    Below is a tailor-made program for your requirement:

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; // Variables to hold the configuration for your cluster. // These will need to be changed to match your actual cluster's values. const rancherClusterId = "<RANCHER_CLUSTER_ID>"; const terraformHelmRepoName = "hashicorp"; const terraformHelmRepoUrl = "https://helm.releases.hashicorp.com"; // Create a new rancher2 provider instance const rancher2Provider = new rancher2.Provider("rancherProvider", { apiVersion: "v1", bootstrap: true, // Set 'true' in order to initialize the `rancher2` provider }); // Add Terraform's Helm chart repository to Rancher const terraformHelmRepo = new rancher2.CatalogV2("terraformHelmRepo", { clusterId: rancherClusterId, name: terraformHelmRepoName, url: terraformHelmRepoUrl, helmVersion: "v3", }, { provider: rancher2Provider }); // Use the Kubernetes provider to deploy Terraform Cloud Helm chart via Rancher const terraformHelmChart = new k8s.helm.v3.Chart("terraform-cloud", { chart: "terraform-cloud", version: "0.1.0", // Specify the version of the Helm chart you want to deploy namespace: "default", // Namespace where you want to deploy the Helm chart fetchOpts: { repo: terraformHelmRepoUrl, }, }, { provider: new k8s.Provider("k8s", { kubeconfig: rancher2Provider.kubeconfig }) }); // Export the Helm chart deployment name export const terraformCloudHelmChartName = terraformHelmChart.metadata.name;

    In the above program:

    1. We're importing the @pulumi/rancher2 and @pulumi/kubernetes modules to interact with Rancher and Kubernetes, respectively.

    2. We then create a new Rancher provider instance that will allow us to interact with our Rancher server.

    3. The terraformHelmRepo creates a CatalogV2 resource which registers the HashiCorp Helm repository with the Rancher cluster indicated by rancherClusterId.

    4. We declare a terraformHelmChart using Pulumi's Helm package in the Kubernetes provider to deploy the Terraform Cloud Helm chart into the Rancher-managed Kubernetes cluster using the newly added Helm repository's details.

    5. The terraformHelmChart resource's chart parameter is set to "terraform-cloud", which specifies the name of the Helm chart we wish to deploy.

    6. Finally, we export the Helm chart deployment name for easy reference and querying on the cluster.

    Please ensure that you replace the placeholders (<RANCHER_CLUSTER_ID>, chart version, and other necessary configuration values) with the correct values that correspond to your environment and needs.

    Ensure that you run npm install to install the dependencies once the Pulumi.yaml has been configured. Then, you can deploy your stack with pulumi up. Pulumi will print out the status of the resources it's creating. Once it’s done, it will output any stack exports you’ve specified.
