1. Deploy the pubsub-emulator helm chart on Opensshift

    TypeScript

    To deploy the pubsub-emulator Helm chart on OpenShift using Pulumi, we can utilize the kubernetes.helm.v3.Chart class from the Pulumi Kubernetes provider. This class allows you to deploy Helm charts into a Kubernetes cluster managed by OpenShift.

    Before starting with the actual Pulumi code, ensure you have the following prerequisites in place:

    1. Pulumi CLI installed on your local machine.
    2. Access to an OpenShift cluster with kubectl configured to communicate with it.
    3. Helm CLI installed if you need to customize the Helm chart before deploying through Pulumi.

    Below is a Pulumi program written in TypeScript that demonstrates how to deploy the pubsub-emulator Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Helm Chart. // This assumes you have the Helm chart information such as repository URL // or a local path to the chart. const pubsubEmulatorChart = new k8s.helm.v3.Chart("pubsub-emulator", { chart: "pubsub-emulator", // The repository where the Helm chart is located. // Change this to the actual repository URL if the chart is not in the public Helm repo. // You can also use a local path to the chart directory if needed. // repo: "<URL to your Helm chart repository>", version: "0.1.0", // Specify the version of the chart you wish to deploy. namespace: "default", // Choose the namespace where you want to deploy the chart. // If you want to pass any specific values to the Helm chart, specify them here. // values: { // key1: value1, // key2: value2, // }, // For example, if the chart has configurable port for the emulator, it can be set like this: // values: { // service: { // port: 8085 // } // } }); // Export the service name to access the pubsub-emulator once it's deployed export const pubsubEmulatorServiceName = pubsubEmulatorChart.getResourceProperty("v1/Service", "pubsub-emulator", "metadata").name;

    In the above code, replace the placeholder values with the appropriate values for your Helm chart, such as the repository URL and version. The values object inside the chart instantiation can be used to customize the deployment by overriding the default values defined in the values.yaml file of the Helm chart.

    To apply this Pulumi program:

    1. Save this code in a file with a .ts extension, such as index.ts.
    2. Run npm init in the folder where you saved the file to create a package.json.
    3. Run npm install @pulumi/kubernetes to install the necessary Pulumi Kubernetes package.
    4. Use the pulumi up command to preview and deploy the changes. Pulumi will ask for confirmation before proceeding with the actual deployment.

    Upon successful deployment, Pulumi will output the service name of the pubsub-emulator that you can use to interact with the emulator.

    Keep in mind that deploying to OpenShift might sometimes require additional configuration or permissions, depending on your OpenShift cluster setup, because OpenShift employs stricter security constraints compared to standard Kubernetes installations.
