Deploy the frontier-squid helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `frontier-squid` Helm chart on an AWS EKS cluster using Pulumi, you will need to perform the following steps:

1. Create an EKS cluster using the Pulumi AWS provider. In this example, we'll use the `awsx` package, which provides a higher-level abstraction over AWS resources, including EKS.
2. Use the Pulumi Kubernetes provider to deploy the `frontier-squid` Helm chart to the EKS cluster you've created.

Below is a detailed TypeScript program that demonstrates these steps:

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

// Step 1: Create an EKS cluster
// This will create an EKS cluster with the default configurations which includes a default node pool (the set of EC2 instances)
const cluster = new eks.Cluster("my-cluster");

// Step 2: Deploy the frontier-squid Helm chart
// This assumes the Helm chart is available in a reachable Helm repository
const squidChart = new k8s.helm.v3.Chart("frontier-squid", {
    // It's important to run this Helm chart within the EKS cluster we created
    // Providing the kubeconfig from the created EKS cluster is necessary for Pulumi to know where to deploy the Helm chart
    kubeConfig: cluster.kubeconfig.apply(JSON.stringify),
    chart: "frontier-squid",
    // If the chart is in a specific repository, specify it with `repo` property
    // Otherwise, Pulumi will attempt to find it in the default stable repository
    version: "desired-chart-version", // specify the chart version here
    // Values to configure the Helm chart
    values: {
        // ... any required values for the frontier-squid chart
    },
    namespace: "default" // target namespace for deployment
}, { provider: cluster.provider });

// Export the cluster's kubeconfig and the service endpoint
export const kubeconfig = cluster.kubeconfig;
export const squidServiceEndpoint = squidChart.getResourceProperty("v1/Service", "frontier-squid", "status")
    .apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);
```

This program consists of two major parts:

- `eks.Cluster`: This line creates a new EKS cluster. The `awsx` package is designed to simplify the cluster creation process by automatically setting up the VPC, subnets, and node group along with other necessary configurations.
    - You can find more information about the EKS cluster component [here](https://www.pulumi.com/docs/guides/crosswalk/aws/eks/).

- `k8s.helm.v3.Chart`: This line creates a new Helm chart deployment in the just-created EKS cluster. The `frontier-squid` chart is fetched from the specified Helm repository (if any) and deployed with the provided configuration values.
    - You can find more information about deploying Helm charts with Pulumi [here](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/).
 
The configuration values for the Helm chart would be specific to `frontier-squid` and will need to be filled in accordance with the Helm chart's documentation and your specific requirements.

After you've written this code into a `index.ts` file of a Pulumi project, you can deploy the infrastructure with the following Pulumi CLI commands:

```bash
pulumi up # Preview and deploy changes
```

Remember to configure AWS credentials and Pulumi before running the pulumi CLI. You will also need to have kubectl installed to interact with your Pulumi-managed EKS cluster directly. To access your cluster through kubectl, you can use the exported `kubeconfig` file from the pulumi stack output.
