1. Deploy the scheduler-plugins helm chart on Kubernetes

    TypeScript

    To deploy a Helm chart using Pulumi, you can leverage the Chart resource available in Pulumi's Kubernetes provider. In the context of this task, I'm going to assume that you have the scheduler-plugins Helm chart available either in a public Helm repository or you have the chart files available locally.

    Firstly, you'd need to install the Pulumi CLI and set up your Kubernetes cluster. I'm assuming you've already done so and have your Kubernetes cluster context correctly configured.

    Next, let's go through the process step-by-step:

    1. Initialize a New Pulumi Project: This is typically done using the Pulumi CLI with commands such as pulumi new; however, in the interest of focusing purely on the code, we'll assume the project is already set up.

    2. Import the Necessary Packages: This includes both pulumi itself and the Kubernetes provider @pulumi/kubernetes.

    3. Write the Deployment Script: The script defines a Chart resource, which represents the Helm chart you want to deploy. You'll need to provide the chart's name and additional parameters such as the repository or path (if local), and any configurations required by the chart packaged in the values property.

    4. Export Any Necessary Outputs: This is useful for retrieving any information about the deployed resources that you may need, such as an endpoint.

    Now, let's proceed with the actual Pulumi TypeScript program:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Helm Chart for the scheduler-plugins. // You need to specify the repository and chart name, or if it's local, specify the path. // You may also need to specify a version number and any custom values which "scheduler-plugins" requires. const schedulerPluginsChart = new k8s.helm.v3.Chart("scheduler-plugins", { // Assuming 'scheduler-plugins' is in a Helm repo repo: "my-helm-repo", // Replace with the actual repository name chart: "scheduler-plugins", // Specify the chart version (optional but recommended for production to ensure repeatable deployments) version: "1.0.0", // Replace with the actual chart version needed // Override default configuration values // These are chart specific and could include things like the image tag, resources, and more. values: { // Here the configuration values go. E.g.: // image: { // repository: "my-repo/scheduler-plugins", // tag: "latest" // }, }, // Specify the namespace where this chart will be installed (optional, defaults to 'default') namespace: "kube-system", // Replace with your desired namespace }); // Export any needed values from the Helm chart that might be needed. // For instance, if your chart creates a LoadBalancer service and you want to export its external IP: export const schedulerPluginsServiceIP = schedulerPluginsChart.getResourceProperty("v1/Service", "my-service", "status") .apply(status => status.loadBalancer.ingress[0].ip); // Note: Ensure the service, its name 'my-service', and the properties align with your actual Helm chart's resources

    This code demonstrates how to deploy a Helm chart called scheduler-plugins. It specifies the required repository (this should be the name of the Helm repository where scheduler-plugins is hosted), the chart name, optional values you might want to override, and the Kubernetes namespace to deploy to.

    Finally, it exports an IP address of a potentially resulting service; you will need to replace "my-service" with the actual name of the service created by your Helm chart if you wish to export such values.

    To execute this Pulumi program:

    • Save this code to a file named index.ts in the root of your Pulumi project directory.
    • Run pulumi up from the command line to preview and then apply the changes. Your CLI will interactively show you the resources that will be created and prompt you for confirmation before applying.
