1. Deploy the ibm-apic-instance helm chart on Kubernetes


    To deploy a Helm chart on a Kubernetes cluster using Pulumi, you'll need to use the @pulumi/kubernetes package, which contains the necessary tools to interact with Kubernetes resources. In this case, you can use the Chart resource provided by the helm.sh/v3 module to deploy the ibm-apic-instance chart.

    First, ensure you have the proper set up:

    • You have a Kubernetes cluster running and have access to it with kubectl.
    • Pulumi CLI installed and you're authenticated to use it.
    • Node.js and npm or Yarn installed to work with TypeScript and install the necessary Pulumi packages.

    Here, I will guide you through writing a Pulumi program in TypeScript to deploy the ibm-apic-instance Helm chart to your Kubernetes cluster. This will include setting up the new Pulumi project, installing necessary dependencies, and crafting the TypeScript code for the deployment.

    Create a new Pulumi project and set it up to use TypeScript:

    pulumi new kubernetes-typescript

    Next, navigate to your project's directory and install the @pulumi/kubernetes package if it's not already installed:

    npm install @pulumi/kubernetes

    Now, let's write a TypeScript program that will deploy the ibm-apic-instance Helm chart. For this, you'll need to have the Helm repository added that contains the ibm-apic-instance chart, and you'll need to know the exact version of the chart you wish to deploy. If you require specific values for the Helm chart, you can provide them in a values object within the Chart resource.

    Here's how you would write the Pulumi TypeScript program to accomplish this:

    import * as k8s from "@pulumi/kubernetes"; // Create a Helm Chart resource. This example assumes you have already set up and connected to your Kubernetes // cluster, and Helm and Pulumi are configured correctly. const apicInstanceChart = new k8s.helm.v3.Chart("ibm-apic-instance", { // Use `repo` to reference the repository that contains the chart. // Replace `my-repo` with the actual Helm repository name that hosts the `ibm-apic-instance` chart. // If your chart exists in a local directory, you can also use the `path` parameter instead. repo: "my-repo", chart: "ibm-apic-instance", // If your chart needs specific configurations, provide them under `values`. // This is an empty object template as an example, place your own values as needed. values: { // Place configuration values here, e.g., size of storage, names of ConfigMaps, etc. // size: "large", // configMapName: "my-config-map", }, // Specify which namespace the chart will be installed into. // Replace this value if you need to install it into a different namespace. namespace: "default", // If the chart version is important (it usually is), then specify it. // Replace `1.2.3` with the actual version you wish to deploy. version: "1.2.3", }); // Optional: You can export the resultant deployment's properties export const deploymentName = apicInstanceChart.getResourceProperty("v1/Deployment", "ibm-apic-instance", "metadata").apply(m => m.name);

    In the code snippet provided:

    • We import the Pulumi Kubernetes package.
    • We create a new instance of a Helm chart.
    • We specify the repository name (my-repo) — you should replace this with the name of the repository containing your chart.
    • We specify the chart name (ibm-apic-instance).
    • We provide an example of how to pass custom values to the chart with the values object.
    • We define the namespace for deployment. Replace "default" with your target namespace.
    • We specify the version of the Helm chart we want to deploy. Make sure you replace 1.2.3 with the correct chart version you intend to deploy.
    • Lastly, we provide an optional export of the deployment name, which can be accessed after running pulumi up to apply the changes to your cluster.

    Now, this program can be executed using the Pulumi CLI by running pulumi up, which will perform the deployment to your Kubernetes cluster.
