1. Deploy the redis-cart helm chart on AWS EKS


    To deploy the redis-cart Helm chart on AWS EKS using Pulumi, we'll follow these steps:

    1. Create an EKS Cluster: We'll use the eks.Cluster component from the eks package to create a managed Kubernetes cluster on AWS. This resource abstracts away a lot of the details needed to set up an EKS cluster and makes it very simple to get a cluster up and running.

    2. Define EKS Role: You will need to set up the necessary IAM roles for EKS with the aws-iam.EKSRole resource from the aws-iam package. This typically includes a role that the EKS service will assume to create AWS resources such as EC2 instances for the Kubernetes nodes.

    3. Create Node Group: We'll add a node group to the EKS cluster using the eks.NodeGroup resource to define the EC2 instances that will serve as worker nodes for the Kubernetes cluster.

    4. Deploy Helm Chart: Finally, we’ll use the helm.v3.Chart resource to deploy the redis-cart Helm chart on the EKS cluster that we've created.

    Below is the TypeScript program that accomplishes this. Each step includes inline comments explaining what the code does:

    import * as pulumi from '@pulumi/pulumi'; import * as aws from '@pulumi/aws'; import * as awsx from '@pulumi/awsx'; 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-eks-cluster', {}); // Exports the kubeconfig to connect to the cluster export const kubeconfig = cluster.kubeconfig; // Deploy the `redis-cart` helm chart on the EKS cluster const redisCartChart = new k8s.helm.v3.Chart('redis-cart', { chart: 'redis-cart', version: '1.2.3', // replace with the specific chart version you want to deploy fetchOpts: { repo: 'http://charts.myhelmrepo.com', // replace with the actual helm chart repository URL }, }, { provider: cluster.provider }); // Export the endpoint of the EKS cluster export const clusterEndpoint = cluster.core.endpoint; // We must export the cluster's kubeconfig so that a client can easily access our cluster. export const kubeconfig = pulumi.secret(cluster.kubeconfig); // Run `pulumi up` to deploy the resources and helm chart // The `kubeconfig` will be printed as an output that you can use with `kubectl` to interact with your EKS cluster // The `clusterEndpoint` is the entry point for your EKS cluster's API server, useful for connecting Kubernetes tools such as `kubectl`

    Make sure the version and the repo in the redisCartChart declaration accurately reflect the version and repository of the Helm chart you wish to deploy.

    After running the pulumi up command, Pulumi will provision the required AWS and Kubernetes resources and deploy your chart.

    Once the command completes successfully, it will output the kubeconfig that you can use to manage your Kubernetes cluster with kubectl. To ensure the security of your cluster, remember to treat your kubeconfig with the same caution and security considerations as you would with any other credential.
