1. Deploy the supertubes-control-plane helm chart on Opensshift


    To deploy the supertubes-control-plane Helm chart on an OpenShift cluster using Pulumi, we can utilize the kubernetes provider that Pulumi offers. First, make sure you have access to your OpenShift cluster and kubectl is configured to connect to it. Pulumi's Kubernetes provider will use the configuration from kubectl by default.

    Below is a Pulumi program written in TypeScript to deploy the supertubes-control-plane Helm chart. In this example, we will use the Chart class from Pulumi's Kubernetes provider to specify the chart we wish to install. You need to specify the chart name and the repository from which it can be fetched if it's not a stable Helm chart that's available by default.

    Before you run the code, you should have Pulumi installed and setup on your computer, and be logged into an account where your Pulumi state will be saved. Also, make sure that Helm is installed and configured for use with your cluster, as Pulumi interacts with Helm to deploy charts.

    Here is the Pulumi program:

    import * as kubernetes from "@pulumi/kubernetes"; // Create an instance of the Kubernetes provider connected to the existing OpenShift cluster. const provider = new kubernetes.Provider("openshift-provider", { // You can customize provider settings here, such as setting the kubeconfig explicitly. }); // Define the Helm chart for the supertubes-control-plane application. const supertubesControlPlaneChart = new kubernetes.helm.v3.Chart("supertubes-control-plane", { // Specify the chart name, repository, and version if necessary. chart: "supertubes-control-plane", // Replace with the correct repository containing the supertubes-control-plane chart. fetchOpts: { repo: "https://your-helm-chart-repository.com/" }, // Specify which namespace the chart should be installed into. namespace: "supertubes-control-plane-namespace", // Include additional configuration here if needed. values: { // Provide any specific configuration required by the supertubes-control-plane chart. }, }, { provider }); // Pass the provider to let Pulumi know which cluster to deploy to. export const chartName = supertubesControlPlaneChart.name;

    To explain the code:

    • We import the Kubernetes package provided by Pulumi, which allows us to work with Kubernetes resources.
    • We instantiate a Provider that represents the OpenShift cluster. This will use the current context set in your local kubectl configuration.
    • We create a new Helm Chart resource, specifying the name supertubes-control-plane. We also need to provide the repository where the chart is hosted, the namespace we want to install it to, and any values that customize our installation. The fetchOpts property is used to specify the Helm chart's repository.
    • The provider option is passed to the chart to specify which Kubernetes provider to use for deploying the Helm chart. Here we connect it to the OpenShift cluster.
    • We export the chart name using a Pulumi output variable. This isn't necessary but can be useful if you need to reference the deployed chart from other code.

    Before running this program, be sure to replace "https://your-helm-chart-repository.com/" with the actual repository URL where your supertubes-control-plane Helm chart is located.

    To deploy this chart:

    1. Save the code to a file named index.ts.
    2. Run pulumi up in the same directory as your index.ts file. Pulumi will perform a preview of the deployment and ask for confirmation before proceeding.
    3. Confirm the action, and Pulumi will deploy the Helm chart to your OpenShift cluster.

    Remember that pulumi up will result in real changes to your infrastructure based on the code you've written. Always review the preview before confirming the deployment.
