1. Deploy the yace-exporter helm chart on Opensshift

    TypeScript

    Deploying a Helm chart on an OpenShift cluster with Pulumi involves several steps. Here we will create a program that uses Pulumi's Kubernetes provider to achieve this. We'll utilize the kubernetes.helm.v3.Chart resource to deploy the yace-exporter Helm chart, which is presumably a chart for deploying the Yet Another Cloudwatch Exporter (YACE) on Kubernetes/OpenShift.

    First, let's set up the Pulumi Kubernetes provider to interact with the OpenShift cluster. With Pulumi, you would typically already have kubectl configured to point to your OpenShift cluster, and Pulumi will use that same configuration.

    Here's what the Pulumi program in TypeScript looks like, including the installation of the yace-exporter Helm chart on OpenShift:

    import * as k8s from "@pulumi/kubernetes";

// Create an OpenShift cluster instance. This assumes you have a kubeconfig file set up to connect to your OpenShift cluster.
const openshiftCluster = new k8s.Provider("openshiftCluster", {
    // Pulumi automatically uses the current context in your kubeconfig file.
    // If you need to override this behavior to point to a specific context, use the 'kubeconfig' property.
});

// Deploy yace-exporter Helm chart on the OpenShift cluster using the Helm Chart resource.
// This example assumes that 'yace-exporter' is available in a public Helm chart repository.
// If it's in a private repository, you'll need additional configuration for repository access.
const yaceExporter = new k8s.helm.v3.Chart("yace-exporter", {
    repo: "yace-repo", // Replace with your Helm chart's repository name.
    chart: "yace-exporter", // The chart name, which we're assuming is 'yace-exporter'.
    // Optional: specify the chart version you want to deploy.
    version: "0.1.0", // Replace with your desired chart version.
    // Optional: 'values' is an object that allows you to override key-value pairs defined in the chart's 'values.yaml'.
    values: {
        // Replace these with actual configuration values required by 'yace-exporter', based on its documentation.
        serviceAccount: {
            create: true,
            name: "yace-exporter-sa",
        },
        // Add any other values that are required for configuring the YACE exporter.
    },
}, { provider: openshiftCluster }); // Pass the OpenShift provider instance.

// Export the service endpoint as an output of the Pulumi program.
// Supply the appropriate resource attributes to retrieve the correct endpoint.
// For example, if the service type is LoadBalancer, then you would export the load balancer's ingress:
export const yaceExporterEndpoint = yaceExporter.getResourceProperty("v1/Service", "yace-exporter", "status").apply(status => status.loadBalancer.ingress[0].ip);

    This Pulumi program will deploy the yace-exporter Helm chart to your OpenShift cluster:

    1. It imports the Pulumi Kubernetes library which contains necessary classes and functions.
    2. A Provider instance is created, which encapsulates the connection to the OpenShift cluster.
    3. A Chart instance is created which declares the deployment of the yace-exporter Helm chart using the OpenShift provider.
    4. The repo parameter specifies the name of the repository containing the yace-exporter Helm chart.
    5. The chart parameter specifies the precise name of the Helm chart to deploy.
    6. The values parameter is a map that can override default values in the chart's values.yaml. Here, the service account details are supplied to match OpenShift security context constraints.
    7. Finally, it exports the endpoint of the deployed service to access the exporter, assuming that the chart creates a LoadBalancer service.

    Make sure to replace the placeholder values for repo, chart, version, and the relevant items inside the values map with actual values suitable for your situation. The comments guide you on which parts of the code to customize for your Helm chart and OpenShift configuration.
