Deploy the caretta helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Caretta Helm chart on an Amazon EKS cluster, you need to follow these steps:

1. **Create an EKS cluster**: You'll need a running Kubernetes cluster on EKS for which you can use Pulumi's EKS package.
2. **Deploy the Helm chart**: Once you have the cluster, you will use Pulumi's Kubernetes provider to deploy your Helm chart to the EKS cluster.

Below is a Pulumi program written in TypeScript which sets up an EKS cluster and deploys the Caretta Helm chart to it. This example assumes that the Caretta Helm chart is publicly available in a Helm repository.

You need to replace `YOUR_HELM_REPO_URL` with the actual Helm repository URL and `YOUR_CHART_VERSION` with the version of the Caretta chart you want to deploy. If the Helm chart is not in a remote repository and is instead stored locally, you'll want to use the `path` option rather than `repo` and `chart`.

```typescript
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 version for the cluster
    version: "1.21",
    // Deploy the cluster with the default configuration
    // For production use, you should customize the configuration.
    // Refer to the EKS Cluster documentation for details:
    // https://www.pulumi.com/registry/packages/eks/api-docs/cluster/
});

// Once the cluster is up and ready, we can create a Kubernetes Provider pointing to the cluster's kubeconfig.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the Caretta Helm chart using Kubernetes provider.
const carettaChart = new k8s.helm.v3.Chart("caretta", {
    chart: "caretta-chart-name", // Replace with the Caretta chart name in the repository
    version: "YOUR_CHART_VERSION", // Specify the version of the Caretta chart
    repo: "YOUR_HELM_REPO_URL", // Specify the Helm repository URL here
    // You can pass any required values for your Helm chart here
    // For this example, we are not passing any values, assuming default values would suffice.
    // You can define values like this: values: { key: "value" },
}, { provider: k8sProvider });

// Export the kubeconfig and the cluster's name
export const kubeconfig = cluster.kubeconfig;
export const clusterName = cluster.core.cluster.name;

// Run 'pulumi up' to deploy the EKS cluster and the Caretta Helm chart
```

This Pulumi program will create a new EKS cluster and deploy the Caretta Helm chart. Remember to run `pulumi up` to initiate the deployment process.

Please ensure you have AWS credentials configured on your environment where Pulumi CLI will run. For the EKS creation, you would need appropriate permissions to create related resources on AWS.

These steps demonstrate how Pulumi can be used for deploying Helm charts on an EKS cluster. Since Pulumi is an Infrastructure as Code tool, these additional benefits come along:

- Version control for your infrastructure.
- Reusability of code across deployments.
- The ability to define your infrastructure alongside your application code for better integration and collaboration between development and operations teams.
