Deploy the sonarqube-scanner helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the SonarQube scanner Helm chart on a Kubernetes cluster using Pulumi, you need to utilize the `helm.v3.Chart` resource from Pulumi’s Kubernetes provider. The `Chart` resource is a high-level component that streamlines the usage of Helm charts without the need for the Helm CLI, directly through Pulumi.

Before diving into the code, here’s a step-by-step breakdown of what the program does:

1. **Import the necessary Pulumi packages**: We begin by importing the Kubernetes package to interact with the Kubernetes resources.
2. **Create a Helm Chart Resource**: With the Kubernetes package, we use the `helm.v3.Chart` resource to deploy the SonarQube scanner.
3. **Specify Helm Chart Details**: Provide the name of the Helm chart, the repository where it's hosted, and any specific configurations (values) needed by the chart.

Below is a TypeScript program that implements the above steps. It assumes you have a running Kubernetes cluster and have configured Pulumi to use the appropriate kubeconfig file to interact with your cluster.

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

// This is the name we'll use to refer to the Helm chart, not to be confused with the actual chart name.
const chartName = "sonarqube-scanner";
const chartVersion = "X.Y.Z"; // Replace X.Y.Z with the actual chart version you want to deploy.
const helmRepoName = "sonarqube"; // Replace with the Helm repository name hosting the SonarQube chart.
const helmRepoUrl = "https://charts.sonarqube.org/"; // Replace with the Helm repository URL.

// Deploy SonarQube scanner using a Helm chart.
const sonarqubeScannerChart = new k8s.helm.v3.Chart(chartName, {
  repo: helmRepoName,
  chart: chartName,
  version: chartVersion,
  fetchOpts: {
    repo: helmRepoUrl
  }
}, { provider: clusterProvider });

// Export the front-end Service name and address where SonarQube scanner can be accessed.
export const sonarqubeServiceName = sonarqubeScannerChart.getResourceProperty("v1/Service", `${chartName}-sonarqube-scanner`, "metadata").then(metadata => metadata.name);
export const sonarqubeServiceAddress = sonarqubeScannerChart.getResourceProperty("v1/Service", `${chartName}-sonarqube-scanner`, "status").then(status => status.loadBalancer.ingress[0].ip);

```

In the program above, you need to replace the placeholders like `X.Y.Z` with the specific version of the SonarQube scanner Helm chart you want to deploy. Additionally, you should replace the `helmRepoName` and `helmRepoUrl` with the actual repository details where the SonarQube scanner chart is hosted.

At the end of the script, we export the service name and external IP address (if using LoadBalancer type) of the SonarQube scanner service, which allows you to access this deployment from outside the cluster.

To apply this Pulumi program:

1. Save the code to a file with a `.ts` extension (e.g., `deploySonarqubeScanner.ts`).
2. Run `pulumi up` from the command line in the same directory as your code file.
3. Pulumi will perform a preview run and show you the proposed changes.
4. If the preview looks good, confirm the deployment, and Pulumi will proceed to deploy the Helm chart to your Kubernetes cluster.

Remember, this program assumes that you have a Kubernetes cluster already running and kubectl is configured on your machine to interact with it. The Pulumi program leverages the existing kubeconfig to communicate with your cluster.
