Deploy the zipkin-stackdriver-proxy helm chart on Rancher

To deploy a Helm chart on a Rancher-managed Kubernetes cluster through Pulumi, we need to create a Pulumi program that interacts with Rancher to deploy our desired Helm chart, which in this case is zipkin-stackdriver-proxy. The Helm chart itself is not explicitly represented in the Pulumi Registry Results, but we can still use Pulumi's rancher2 provider to interact with a Rancher Kubernetes cluster.

Here’s a breakdown of the steps we would follow to achieve this in the Pulumi TypeScript programming language:

1. Set up Rancher configuration – We would require access to a Rancher server to manage Kubernetes clusters.
2. Initialize the Rancher provider – The rancher2 provider allows us to interact with Rancher resources.
3. Create a Kubernetes cluster (if it doesn't already exist) and obtain a kubeconfig to interact with it.
4. Install the Helm chart using the kubeconfig with Pulumi's Kubernetes provider.

Below is a Pulumi program in TypeScript that sets up the Rancher provider, assumes the existence of a Kubernetes cluster in Rancher, and then deploys the zipkin-stackdriver-proxy Helm chart to it. Please note that this assumes you have already set up and configured your Pulumi and Rancher environments appropriately.

import * as pulumi from '@pulumi/pulumi';
import * as k8s from '@pulumi/kubernetes';
import * as rancher2 from '@pulumi/rancher2';

// Initialize a new Rancher provider instance.
// Make sure to configure the provider with the appropriate Rancher server URL and access credentials.
const rancherProvider = new rancher2.Provider('my-rancher-provider', {
    apiVersion: 'v1',
    baseUrl: 'https://<RANCHER_SERVER>',
    accessKey: '<RANCHER_ACCESS_KEY>',
    secretKey: '<RANCHER_SECRET_KEY>',
});

// We will use the following kubeconfig to connect to our cluster.
// Replace this with your actual kubeconfig.
const kubeconfig = '<YOUR_KUBECONFIG>';

// Initialize a new Kubernetes provider instance using the kubeconfig from the Rancher cluster.
const k8sProvider = new k8s.Provider('my-k8s-provider', {
    kubeconfig: kubeconfig,
});

// We will now deploy the `zipkin-stackdriver-proxy` Helm chart.
// You will need the repository URL where the Helm chart is located.
const chart = new k8s.helm.v3.Chart('zipkin-stackdriver-proxy', {
    chart: 'zipkin-stackdriver-proxy',
    version: '<CHART_VERSION>', // Specify the chart version you want to deploy.
    fetchOpts: {
        repo: 'https://<HELM_REPO_URL>', // Replace with the Helm repository URL.
    },
}, { provider: k8sProvider });

// Export the name of the chart.
export const chartName = chart.metadata.apply(metadata => metadata.name);

In this program:

• We have imported the necessary Pulumi packages for Rancher (@pulumi/rancher2) and Kubernetes (@pulumi/kubernetes).
• We instantiated a new Rancher provider with credentials and server URL, which gives us the ability to interact with the Rancher API.
• We assumed the existence of a Kubernetes cluster managed by Rancher, and thus we already have kubeconfig for this cluster.
• We then created a Kubernetes provider instance, which is initialized using the kubeconfig from the Rancher cluster. This provider is used to manage Kubernetes resources.
• With the Kubernetes provider configured, we deployed the zipkin-stackdriver-proxy Helm chart from the specified Helm repository. Replace <CHART_VERSION> with the chart version you wish to deploy and <HELM_REPO_URL> with the URL of the Helm repository containing the chart.

Please ensure you have the correct Helm chart name, version, and repository URL before proceeding, as they will need to be supplied in place of the placeholders.

Before running this Pulumi program, make sure to replace placeholders <RANCHER_SERVER>, <RANCHER_ACCESS_KEY>, <RANCHER_SECRET_KEY>, and <YOUR_KUBECONFIG> with actual credentials and configuration for your Rancher installation and managed Kubernetes cluster.

To run this program, save the code to a file with a .ts extension, navigate to the directory containing this file in your terminal, and then execute pulumi up to preview and deploy the stack. Ensure you have the Pulumi CLI installed and are logged in to your Pulumi account. If needed, you can create a new Pulumi stack with pulumi stack init.
