1. Deploy the terraform-cloud helm chart on Linode Kubernetes Engine


    To deploy a Helm chart on a Kubernetes cluster provisioned by the Linode Kubernetes Engine (LKE) using Pulumi, you'll need to perform the following steps:

    1. Provision a Kubernetes cluster with LKE. (Assuming you've done this already or have an existing cluster, we'll skip this step.)
    2. Set up the necessary configuration to connect to your LKE cluster from your local machine.
    3. Use the Pulumi Kubernetes provider to deploy the Helm chart to the LKE cluster.

    Here's a Pulumi TypeScript program that demonstrates how to deploy the Terraform Cloud Helm chart to an existing LKE cluster. Note that before running this code, you need to have Pulumi installed on your machine, have access to your LKE cluster's kubeconfig file, and have it set up to point to your cluster.

    First, let's explain what each part of the program does:

    • kubernetes.Provider: This Pulumi resource enables you to set up a Kubernetes provider to connect to your cluster. You should have the kubeconfig file for your LKE cluster ready to use.
    • kubernetes.helm.v3.Chart: This resource represents a Helm chart that you can deploy to your Kubernetes cluster. You specify the chart name, which repository it's in, and any other configuration it needs.

    Below is the Pulumi program to deploy the Terraform Cloud Helm chart to an LKE cluster:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; // Initialize a Kubernetes provider with the kubeconfig from your Linode Kubernetes Engine (LKE) cluster. const provider = new kubernetes.Provider("lkeK8sProvider", { kubeconfig: "<YOUR_LKE_CLUSTER_KUBECONFIG>", // Ensure that this kubeconfig is configured correctly to point to your LKE cluster }); // Deploy the terraform-cloud Helm chart to your LKE cluster. const terraformCloudChart = new kubernetes.helm.v3.Chart("terraform-cloud", { // Assuming the terraform-cloud chart is in a repository added to Helm, include the repo name and chart name here. // If it's a custom chart or you haven't added the repository to Helm, you may need to specify additional details like the `repo` URL. chart: "terraform-cloud", // If you know the version of the chart you want to deploy, uncomment the following line and specify the version. // version: "<CHART_VERSION>", namespace: "default", // You can specify another namespace if you wish values: { // Here you would put any specific configuration options that the chart requires to run, or any overrides you want to set. // As an example: // key: "value", }, }, { provider }); // Make sure to pass the provider that points to your LKE cluster. // Export the URL to access the deployed Helm chart service if it exposes any. // This would depend on whether the chart creates a LoadBalancer service, NodePort, etc. // If the chart does not expose any services, or you do not need any URLs, you can comment out or remove this export. export const serviceUrl = terraformCloudChart.getResourceProperty("v1/Service", "terraform-cloud", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    Steps to Run the Program

    To run the Pulumi program, follow these steps:

    1. Save the above program in a file called index.ts in a new directory.
    2. Navigate to that directory in your terminal.
    3. Run pulumi stack init <STACK_NAME> to create a new Pulumi stack, where <STACK_NAME> is the name you want to give to your stack (e.g., dev or production).
    4. Replace <YOUR_LKE_CLUSTER_KUBECONFIG> in the program with the actual kubeconfig content from your LKE cluster.
    5. If needed, adjust the Helm chart settings, such as the chart version or specific values that need to be overridden for the chart to run properly.
    6. Run pulumi up to preview and deploy the changes.

    After running pulumi up, Pulumi will reach out to your LKE cluster and deploy the requested Helm chart. Once the deployment is successful, Pulumi will output any exported values, such as the URL to access the service.

    Remember that in order to use this Pulumi program, you should have the Pulumi CLI installed and configured for use with your chosen cloud provider if you haven't done so already. Additionally, you'll need to ensure that you have Helm installed and configured on your machine if you're working with Helm charts directly. The Helm chart name and values provided in the code should match the actual chart you intend to deploy.
