Deploy the keyrock helm chart on AWS EKS

Question

Pulumi · Accepted Answer

Deploying a Helm chart on an AWS EKS cluster involves several steps, including setting up an EKS cluster, configuring Kubernetes for Helm, and then deploying the Helm chart. Below is a detailed explanation of what the TypeScript program will accomplish, followed by the program itself.

1. **EKS Cluster**: We'll set up an Amazon EKS cluster using the `eks.Cluster` resource. Amazon EKS manages the Kubernetes control plane for us and is a convenient way to run Kubernetes on AWS.
2. **Helm Chart**: To deploy the Keyrock Helm chart, we will use the `kubernetes.helm.v3.Chart` resource which is a part of Pulumi's Kubernetes provider. This resource manages Helm chart deployments to a Kubernetes cluster.

Here's a TypeScript program that deploys the Keyrock Helm chart on an AWS EKS cluster:

```typescript
import * as pulumi from '@pulumi/pulumi';
import * as aws from '@pulumi/aws';
import * as eks from '@pulumi/eks';
import * as k8s from '@pulumi/kubernetes';

// Create an EKS cluster.
const cluster = new eks.Cluster('my-cluster', {
    // Specify the desired capacity and instance types for the worker nodes.
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 2,
    instanceType: 't2.medium',
});

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

// Create a Kubernetes provider instance using the kubeconfig from the EKS cluster.
const provider = new k8s.Provider('k8s', {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy Keyrock Helm chart to the EKS cluster using the Kubernetes provider.
const keyrockChart = new k8s.helm.v3.Chart('keyrock', {
    chart: 'keyrock',
    version: 'X.Y.Z', // Specify the exact chart version you want to deploy.
    fetchOpts: {
        repo: 'https://helm.repo.url/', // Replace with the URL of the chart repository.
    },
}, { provider });

// Export the Keyrock service endpoint.
export const keyrockEndpoint = keyrockChart.getResourceProperty('v1/Service', 'keyrock', 'status').apply(status => status.loadBalancer.ingress[0].hostname);

```

Before running this program, you will need to replace `'https://helm.repo.url/'` with the actual URL for the Keyrock Helm chart repository and specify the exact version of the Keyrock chart with `'X.Y.Z'`. Additionally, the service name `'keyrock'` should match the service defined within the Keyrock Helm chart. After deploying, you can access the Keyrock service using the endpoint hostname exported by `keyrockEndpoint`.

The EKS cluster's configuration, such as the `desiredCapacity`, `minSize`, `maxSize`, and `instanceType`, can be adjusted based on your workload requirements. The instance type chosen here (`t2.medium`) is for demonstration purposes and should be selected according to the resource needs of Keyrock and your applications.

Remember that deploying an EKS cluster incurs costs, and the resources specified in the program should reflect a configuration that balances cost and performance for your specific use-case. Ensure AWS is configured with the necessary permissions, and the Pulumi CLI is set up as well. After this setup is complete, you can run the Pulumi CLI to deploy your infrastructure.
