Deploy the zipkin-stackdriver-proxy helm chart on Opensshift

To deploy the zipkin-stackdriver-proxy Helm chart on OpenShift using Pulumi, you will need to use the Pulumi Kubernetes provider. The Kubernetes provider allows you to interact with Kubernetes resources in your cluster, including Helm charts. OpenShift is compatible with Kubernetes resources, so the same approach applies.

Below is a program written in TypeScript that demonstrates how to deploy a Helm chart to an OpenShift cluster. This program assumes that you have already configured your Pulumi environment to connect with your OpenShift cluster.

First, let's go over the components of the program:

1. Helm Chart: A Helm chart is a collection of pre-configured Kubernetes resources. The zipkin-stackdriver-proxy chart will be referred from a Helm repository where it is hosted.

2. Provider: The Kubernetes provider configured for OpenShift uses your kubeconfig credentials to authenticate with the OpenShift cluster.

3. Chart Resource: The kubernetes.helm.v3.Chart resource from Pulumi defines a Helm chart release. You specify the chart name, version, and any custom configuration that you require for your deployment.

Let's put this all together in a Pulumi TypeScript program:

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

// Assuming you have set up your Pulumi to authenticate with your OpenShift cluster,
// you can create a provider instance to interact with the Kubernetes resources.
const provider = new k8s.Provider('openshift-provider', {
    // You may specify explicit context, cluster, and user values from your kubeconfig.
    // If these fields are omitted, Pulumi uses the current context from the kubeconfig.
    // context: "your-openshift-cluster-context",
});

// This specifies the Helm chart repository where `zipkin-stackdriver-proxy` is hosted.
// Replace `REPO_URL` with the actual repository URL.
const repoUrl = "REPO_URL"; // Example: "https://helm.example.com/"

// If the chart is hosted in a different namespace or requires specific namespace deployment,
// specify the proper namespace value.
const namespace = "default"; // Replace with the desired namespace if needed.

// Create a Chart resource to deploy the `zipkin-stackdriver-proxy` chart.
// You may need to specify the correct chart version and repository from where it is to be fetched.
new k8s.helm.v3.Chart('zipkin-stackdriver-proxy', {
    chart: 'zipkin-stackdriver-proxy', // Chart name in the repository.
    version: 'CHART_VERSION', // Specify the chart version you wish to deploy.
    fetchOpts: {
        repo: repoUrl
    },
    namespace, // Kubernetes namespace where the chart should be deployed.
}, { provider });

// Export the deployment name, which can be useful if you need to reference the deployment
// in other parts of your Pulumi program or for querying status using `kubectl`.
export const deploymentName = 'zipkin-stackdriver-proxy';

Replace REPO_URL and CHART_VERSION with the actual repository URL and the version of the Helm chart that you want to deploy. If the Helm chart requires custom configurations, add a values property in the Chart resource definition and specify the custom values as an object.

This program will deploy the zipkin-stackdriver-proxy Helm chart when you run it using the Pulumi CLI. Make sure you have access to your OpenShift cluster via kubectl configured on your machine to ensure that Pulumi can interact with your cluster.

Please note, you may need to partner with your OpenShift cluster administrator to ensure the Pulumi service account has sufficient permissions to deploy Helm charts and work with other needed resources within the cluster.
