1. Deploy the konnectivity-agent helm chart on Opensshift


    To deploy the konnectivity-agent Helm chart on an OpenShift cluster using Pulumi, you can leverage the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts in a Kubernetes cluster.

    Below is a step-by-step guide on how to use Pulumi with TypeScript to achieve the deployment of the konnectivity-agent Helm chart onto an OpenShift cluster. For this example, I'll be using placeholder values for certain parameters like the chart name and namespace, which you'd replace with the actual values for your specific use case.

    1. Setting up the Pulumi Program: Ensure Pulumi CLI is installed and set up on your machine.
    2. Defining the Cluster: Since we're targeting an OpenShift cluster, make sure you have the kubeconfig file set up correctly, pointing to your OpenShift cluster. Pulumi uses this to communicate with your Kubernetes cluster.
    3. Creating a New Project: Start by creating a new Pulumi project using the following command: pulumi new kubernetes-typescript.
    4. Installing Dependencies: Ensure you have the @pulumi/kubernetes package installed using npm or yarn before running the program.
    5. Implementing the Deployment: Write the TypeScript code that defines the deployment of the Helm chart.

    Here's the TypeScript program for your Pulumi project that would deploy the konnectivity-agent Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Deploy the konnectivity-agent Helm chart on the OpenShift cluster. const konnectivityAgentChart = new k8s.helm.v3.Chart("konnectivity-agent", { // Replace with the correct repository URL and chart name. // Typically a Helm repo is added with `helm repo add` and referenced here. chart: "konnectivity-agent", version: "0.0.1", // Replace with the chart version you intend to deploy. namespace: "default", // Replace with the namespace where you want the chart to be deployed. // If required, you can provide custom values to the Helm chart. // values: { // key1: value1, // key2: value2, // }, }, { provider: openshiftProvider }); // `openshiftProvider` should be configured with your OpenShift cluster's details. // Export the base URL for the konnectivity service, if applicable export const konnectivityUrl = konnectivityAgentChart.getResourceProperty( "v1/Service", "konnectivity-agent", "status" ).apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    In the above program:

    • We import the @pulumi/kubernetes module to interact with Kubernetes resources.
    • We use k8s.helm.v3.Chart to define a Helm chart resource representing the konnectivity-agent chart.
    • You need to specify the Helm chart name and optionally its version.
    • The namespace parameter is where you define which namespace the Helm chart should be deployed into.
    • The values field is optional and allows you to override the default values in the Helm chart.
    • The provider field is used to specify the Pulumi provider that corresponds to the OpenShift cluster; in the code, I've referred to it as openshiftProvider, which you will need to configure with the details of your cluster.
    • Lastly, we have an export statement that can be used to export the IP or hostname of the konnectivity service if your Helm chart exposes such a service.

    Remember, this example assumes that you've already configured your Pulumi environment with access to your OpenShift cluster, such as authenticating via a kubeconfig file. Replace placeholder values with actual values pertinent to your scenario before running this Pulumi program. Once you've set up your Pulumi.yaml file and the index.ts file as shown above, you can deploy the chart using pulumi up in your CLI.
