Deploy the auditbeat helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the Auditbeat helm chart on a Rancher Kubernetes cluster using Pulumi, you need to follow several steps including setting up the Rancher provider, selecting the appropriate cluster, and then deploying the chart via a Helm Release.

First, let's describe the Pulumi resources that we will use:

- `rancher2.Cluster`: This will be used to select the Rancher Managed Kubernetes cluster where you want to deploy the Auditbeat helm chart.
- `Helm Chart`: Since Pulumi does not include direct support for Rancher's Helm implementations, we will use the native Kubernetes provider to install the Helm chart on the cluster after it becomes ready.

Here's a step by step TypeScript program that shows how you might deploy the Auditbeat helm chart in a Rancher-managed Kubernetes cluster:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";

// Assume you have already configured the Rancher2 provider with the required credentials.
// For details, check the provider configuration documentation here:
// https://www.pulumi.com/registry/packages/rancher2/installation-configuration/

// First, select your Rancher2 Kubernetes cluster using rancher2.Cluster resource.
const cluster = new rancher2.Cluster("my-cluster", {
  // Replace this with the actual properties to match your Rancher Kubernetes cluster configuration
  // If your cluster already exists, and you want to import an existing cluster configuration,
  // You would use `import` method with the resource ID.
});

// Wait for the cluster to be imported and then ready to instantiate Kubernetes resources on it.
const kubeConfig = pulumi.output(cluster.kubeConfig).apply(JSON.stringify);

// Instantiate the Kubernetes provider with the kubeConfig from the Rancher Managed cluster.
const k8sProvider = new k8s.Provider("my-k8s-provider", {
  kubeconfig: kubeConfig,
});

// Finally deploy the Auditbeat helm chart in your Kubernetes cluster
const auditbeatChart = new k8s.helm.v3.Chart("auditbeat", {
  chart: "auditbeat",
  version: "7.12.0", // Specify the chart version you want to deploy
  fetchOpts: {
    repo: "https://helm.elastic.co",
  },
}, { provider: k8sProvider });

// Export the KubeConfig and Auditbeat service URL as stack outputs
export const kubeConfigOut = kubeConfig;
export const auditbeatServiceUrl = auditbeatChart.getResourceProperty("v1/Service", "auditbeat", "status").apply(s => `http://${s.loadBalancer.ingress[0].ip}`);
```

This program first uses the `rancher2.Cluster` resource to select your Rancher-managed Kubernetes cluster. Then, it gets the kubeconfig from the cluster which is required to communicate with the Kubernetes API. A Pulumi Kubernetes provider is instantiated using this kubeconfig.

Then, using the Kubernetes provider and the Helm Chart resource from the `@pulumi/kubernetes` package, it deploys the Auditbeat Helm chart onto the selected cluster. You will need to adjust the properties such as the chart version and repo URL based on your requirements. The chart version used here (`7.12.0`) is for illustration purposes and may need to be updated to reflect the version you intend to deploy.

Finally, it exports the kubeconfig and the service URL of the deployed Auditbeat service as stack outputs. These outputs can be used to interact with the Auditbeat service or to further configure the system.

It is important to note that this code assumes you have set up and configured the Pulumi Rancher2 provider with the appropriate credentials, which is not covered in this script. If you need information on configuring the provider, please refer to the official Pulumi documentation: [Rancher2 Provider Configuration](https://www.pulumi.com/registry/packages/rancher2/installation-configuration/).
