1. Deploy the kube-aws helm chart on AWS EKS


    To deploy the kube-aws Helm chart on an AWS EKS cluster, we will perform the following steps:

    1. Create an EKS cluster using the eks.Cluster resource, which provides a high-level abstraction for creating and managing an AWS EKS cluster.
    2. Once the EKS cluster is set up, we'll use the kubernetes.helm.sh/v3.Chart resource from Pulumi's Kubernetes provider to deploy the kube-aws Helm chart on that cluster.

    Let's start with the creation of the AWS EKS Cluster:

    • We'll instantiate an EKS cluster with default settings, but you can customize the configuration to include specific settings like the node instance type, desired capacity, VPC configuration, and more.
    • We'll use the eks.Cluster resource (eks.Cluster documentation) to simplify this process.

    Once the cluster is created, we'll configure Pulumi to use the Kubernetes provider to connect to the created EKS cluster. This involves setting up the kubeconfig so Pulumi can interact with our EKS cluster.

    After that, we deploy the kube-aws Helm chart using the kubernetes.helm.sh/v3.Chart Pulumi resource (kubernetes.helm.sh/v3.Chart documentation), which handles the deployment of Helm charts in Kubernetes clusters.

    Here's how the Pulumi program in TypeScript will look:

    import * as eks from "@pulumi/eks"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. const cluster = new eks.Cluster("my-cluster", { desiredCapacity: 2, // Specify the desired number of worker nodes minSize: 1, // Specify the minimum number of worker nodes maxSize: 3, // Specify the maximum number of worker nodes instanceType: "t2.medium", // Specify the instance type for the worker nodes }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes Provider instance with the kubeconfig from the created EKS cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the kube-aws Helm chart on the EKS cluster using the Kubernetes provider. const kubeAwsChart = new k8s.helm.v3.Chart("kube-aws", { chart: "kube-aws", // You might need to specify the repository where the kube-aws Helm chart is located, like this: // repo: "my-helm-repo", // You can also set version and values for the Helm chart as needed. }, { provider: k8sProvider }); // Export relevant URLs or other outputs for your stack export const kubeAwsEndpoint = pulumi.interpolate`${kubeAwsChart.status}`;

    In this program:

    • We define an EKS cluster named "my-cluster". You can change the parameters as per your requirements.
    • The kubeconfig is exported so that you can use it with kubectl to interact with your cluster from your local machine.
    • We're setting up a new Kubernetes provider to point to our newly created EKS cluster by giving it the kubeconfig.
    • Then, we deploy the kube-aws chart onto this cluster using the Helm Chart resource. We're using placeholder values for the chart and repo; you'll need to replace "kube-aws" and uncomment repo with the actual Helm chart name and repository URL.

    Make sure you have the Pulumi CLI and AWS CLI installed and configured, and that you are logged into your Pulumi account. Run the program with the following commands:

    pulumi up

    This will begin deploying the resources defined above. After the command completes, you will have an EKS cluster running with the kube-aws Helm chart deployed on it.
