Deploy the puppet-forge helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Puppet Forge Helm chart on an AWS EKS cluster using Pulumi, we'll follow these steps:

1. Define the infrastructure required by an EKS cluster, including the required roles and VPC configuration.
2. Create an EKS cluster using the `eks.Cluster` class.
3. Use the `kubernetes.helm.v3.Chart` class to deploy the Puppet Forge Helm chart to the created EKS cluster.

The `eks.Cluster` class provides high-level abstractions that simplify the creation of an EKS cluster. The `kubernetes.helm.v3.Chart` class is a Pulumi resource that allows us to specify a Helm chart to deploy to our Kubernetes cluster.

Here's a program in TypeScript that accomplishes the deployment:

```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 with the default configuration
const cluster = new eks.Cluster("my-cluster", {});

// Deploy the Puppet Forge Helm chart into the EKS cluster
const puppetForgeChart = new k8s.helm.v3.Chart("puppet-forge", {
    chart: "puppet-forge",
    // The namespace in which to deploy the chart, "default" if not specified
    namespace: "default",
    // Additional chart values, if necessary
    values: {},
    // Specify the cluster where the Helm chart will be deployed
    fetchOpts: {
        repo: "https://puppet.github.io/relay-core/", // Replace with the correct Puppet Forge chart repo if this is not correct
    },
}, { provider: cluster.provider });

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

```

In this program:

- We're importing the necessary Pulumi libraries to create resources for AWS, Kubernetes, and specifically the EKS construct (`eks.Cluster`) and the Helm chart (`k8s.helm.v3.Chart`).
- We then create an EKS cluster with a default configuration. This includes default node types, VPC settings, and IAM roles.
- With the cluster available, we proceed to deploy the Puppet Forge Helm chart. Here we need to specify the correct Helm chart name and the repository where the chart is located. Remember to replace `'https://puppet.github.io/relay-core/'` with the actual repository URL of the Puppet Forge Helm chart if different.
- The `kubeconfig` is exported so that it can be used to connect to the EKS cluster with `kubectl`.

Remember to adjust the values and configurations according to your specific requirements, such as setting different namespaces, values, or node counts and types for the EKS cluster. Also, ensure that you have the necessary AWS credentials configured for Pulumi to create resources on your behalf.

To run this Pulumi program, you'll need to have Pulumi installed and configured with AWS credentials. Save this code to a file called `index.ts` in a new Pulumi project directory. Run `pulumi up` to create the EKS cluster and deploy the Puppet Forge Helm chart.
