1. Deploy the nginx-gateway-fabric helm chart on AWS EKS

    TypeScript

    To deploy the nginx-gateway-fabric Helm chart on an AWS EKS cluster using Pulumi, we will perform the following tasks:

    1. Create an EKS cluster.
    2. Deploy the nginx-gateway-fabric Helm chart on the EKS cluster.

    We will use the following Pulumi resources:

    • aws.eks.Cluster: This represents an EKS cluster in AWS. It is used to create and manage the Kubernetes cluster.
    • kubernetes.helm.v3.Chart: This represents a Helm chart for deploying applications on Kubernetes.

    Here's an outline of the steps we'll take in the Pulumi program:

    1. Set up the EKS cluster.
    2. Deploy the Helm chart on the cluster.

    Let's write the Pulumi TypeScript program:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an EKS cluster const cluster = new eks.Cluster("nginx-fabric-eks", { instanceType: "t2.medium", desiredCapacity: 2, minSize: 1, maxSize: 3, storageClasses: "gp2", // AWS-specific storage class for EBS volumes deployDashboard: false // We will not deploy the Kubernetes dashboard }); // Step 2: Deploy the nginx-gateway-fabric Helm chart on the EKS cluster const nginxGatewayFabric = new k8s.helm.v3.Chart("nginx-gateway-fabric", { chart: "nginx-gateway-fabric", version: "1.0.0", // Specify the version of the Helm chart fetchOpts: { repo: "https://charts.example.com/" }, // Replace with the actual repo URL }, { provider: cluster.provider }); // Export the cluster's kubeconfig and the service endpoint export const kubeconfig = cluster.kubeconfig; export const nginxServiceEndpoint = nginxGatewayFabric.getResourceProperty("v1/Service", "nginx-gateway-fabric", "status");

    Explanation:

    1. We create an EKS cluster named nginx-fabric-eks with the desired number of instances and instance types suitable for our application needs, which we set to t2.medium. We specify the storage class gp2 for EBS volumes and disable the deployment of the Kubernetes dashboard as it's optional.

    2. We deploy the nginx-gateway-fabric Helm chart using the k8s.helm.v3.Chart resource. We need to specify the name of the chart and the version; also the repository from where the Helm chart needs to be fetched must be specified (replace "https://charts.example.com/" with the actual repository URL).

      We associate the chart with the EKS cluster's provider to ensure that Pulumi knows to create this Helm chart in our EKS cluster.

    3. We export the kubeconfig for the EKS cluster so that we can interact with our cluster using kubectl or other Kubernetes tools outside of Pulumi.

    4. We attempt to export the service endpoint of the NGINX service; however, given the dynamic nature of Kubernetes resources, this may need additional logic to handle the async resource provisioning and may not always immediately have the expected value.

    To use this program, you would need to save it as index.ts in a Pulumi project directory, ensure you have AWS credentials configured for Pulumi, and then run pulumi up to create the resources. This will set up a new EKS cluster and deploy the specified Helm chart on it.

    Make sure to replace the placeholder Helm chart repository with the actual URL that hosts the nginx-gateway-fabric chart. If there are any configurations required for the chart, you need to define them in the values property of the Helm chart resource.
