1. Deploy the u4a-component helm chart on AWS EKS


    To deploy the u4a-component Helm chart on Amazon EKS (Elastic Kubernetes Service), you will need to first create an EKS cluster, and then deploy the Helm chart onto this cluster. Below I will guide you through creating an EKS cluster using Pulumi with the @pulumi/eks package, which provides convenient higher-level abstractions for working with EKS. After the cluster is set up, I'll show you how to deploy a Helm chart using the @pulumi/kubernetes package.

    First, let's create the EKS cluster. We'll start by defining the role for the EKS cluster, the VPC (if not using an existing one), and the EKS cluster itself. Please note that you should have AWS access configured, either by setting the access keys as environment variables or by configuring the AWS CLI.

    Here's how to define these resources in Pulumi using TypeScript:

    import * as aws from "@pulumi/aws"; import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. const cluster = new eks.Cluster("u4a-cluster", { instanceType: "t2.medium", // Choose the right instance type for your needs 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 }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig;

    After the cluster is created, you will have a kubeconfig file that allows you to interact with your cluster using kubectl.

    The second step is to deploy the u4a-component Helm chart to the EKS cluster we just created:

    // Create a Kubernetes Provider instance that uses our EKS cluster's kubeconfig. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the u4a-component Helm chart into our EKS cluster. const u4aHelmChart = new k8s.helm.v3.Chart("u4a-component-chart", { chart: "u4a-component", // Assuming the Helm chart is in a repository; specify the repository details fetchOpts: { repo: "http://<helm-chart-repository-url>", }, }, { provider }); // Export the resources created by the Helm chart. export const helmResources = u4aHelmChart.resources;

    Make sure to replace <helm-chart-repository-url> with the actual URL of your Helm chart's repository. This piece of code sets up a new Helm chart resource using the Pulumi Kubernetes provider, which is configured to deploy onto the cluster we set up.

    In order to run this code:

    1. Save it in a .ts file in a Pulumi project directory.
    2. Install necessary dependencies by running npm install @pulumi/aws @pulumi/eks @pulumi/kubernetes.
    3. Run pulumi up to preview and deploy the changes.

    Next steps:

    • You will need to configure AWS access for Pulumi as per your organization's security practices.
    • If you wish to customize the chart configuration you can define a values property in the Chart args.
    • Monitor your deployment with the Pulumi CLI or the AWS Management Console to ensure everything is running smoothly.

    Remember, EKS clusters may incur costs in your AWS account, and it's always a good practice to review AWS's pricing documentation and stay within the free tier limits if possible.
