Deploy the sonarqube-scanner helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the SonarQube Scanner Helm chart to an AWS EKS cluster using Pulumi, we'll go through several steps:
1. Set up an EKS cluster on AWS.
2. Deploy the SonarQube Scanner Helm chart on the EKS cluster.

We'll use Pulumi's `aws` and `kubernetes` packages to accomplish this. The `aws.eks.Cluster` class from the `aws` package will help us set up the EKS cluster, while the `kubernetes.helm.v3.Chart` class from the `kubernetes` package will assist us in deploying Helm charts on that cluster.

Below is a TypeScript program that sets up an EKS cluster and deploys the SonarQube Scanner Helm chart to it. Before running this code, you need to ensure that Pulumi CLI and AWS CLI are installed and configured for the correct AWS account and region.

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

// Create an EKS cluster.
const cluster = new awsx.eks.Cluster("sonarqube-cluster", {
    desiredCapacity: 2,  // Modify based on your requirements
    minSize: 1,  // Modify based on your requirements
    maxSize: 3,  // Modify based on your requirements
    instanceType: "t3.medium",  // Choose an appropriate instance type
});

// Export the cluster's kubeconfig.
export const kubeconfig = cluster.kubeconfig;

// Create a k8s provider using the above created EKSCluster's kubeconfig
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the SonarQube Scanner Helm chart using the k8s provider.
// You need to specify the chart version and any custom values required for your setup.
const sonarqubeScannerChart = new k8s.helm.v3.Chart("sonarqube-scanner", {
    chart: "sonarqube",
    version: "x.x.x",  // Specify the chart version
    fetchOpts:{
        repo: "https://charts.sonarqube.org/", // assuming this is the chart's repository
    },
    values: {
        // Specify your custom values. As an example, the service type is set to LoadBalancer.
        service: {
            type: "LoadBalancer",
        },
    },
}, { provider: k8sProvider });

// Optionally, you can export the Helm chart deployment's status.
export const sonarqubeScannerStatus = sonarqubeScannerChart.status;
```

In this program, we declare an EKS cluster with minimum, desired, and maximum capacity settings. The `instanceType` is set to `t3.medium`, but this should be adjusted based on the demand of your SonarQube workload. The `kubeconfig` is exported so you can use it to communicate with your cluster using `kubectl` if required.

The Kubernetes provider is configured with the EKS cluster's kubeconfig to interact with the cluster. Finally, we deploy the SonarQube Scanner using Helm, specifying the chart's name, version, repository, and any additional values you want. The chart's repository is assumed here but you will need to provide the correct Helm repository URL for SonarQube.

To deploy all these resources with Pulumi, you would open your terminal, navigate to your Pulumi project directory, and run `pulumi up`.

Before running this program, be sure you've replaced `"x.x.x"` with the appropriate chart version for SonarQube. Further customization might be necessary depending on the specifics of your use case, which you can pass through the `values` field.

After deployment, you can manage your EKS cluster and SonarQube application using `kubectl` and Pulumi as required.
