1. Deploy the medusa helm chart on AWS EKS

    TypeScript

    Deploying a Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster involves several steps:

    1. Creating the EKS Cluster: We need an EKS cluster to host our Kubernetes resources.
    2. Deploying the Helm Chart: Once the cluster is up, we can deploy applications using Helm, a Kubernetes package manager.

    Here is a program in TypeScript using Pulumi to deploy the Medusa Helm chart on an AWS EKS cluster.

    Step 1: Set up the EKS cluster:

    We will use the eks.Cluster resource from the @pulumi/eks package (documentation) to create an EKS cluster. We also need to set up the associated VPC and subnets for the cluster, but the eks.Cluster resource simplifies this by providing sensible defaults.

    Step 2: Deploy the Helm chart:

    After the EKS cluster is running, we will use the @pulumi/kubernetes package to deploy the Medusa Helm chart on the cluster. We'll utilize the helm.v3.Chart resource (documentation) for this purpose.

    Now let's begin with the TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; 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"); // Once the cluster is created, we can use the kubeconfig it provides to configure the Kubernetes provider. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Now we can deploy Medusa Helm chart to the EKS cluster. const medusaChart = new k8s.helm.v3.Chart("medusa-helm-chart", { chart: "medusa", version: "insert-chart-version-here", // Specify the chart version you wish to deploy fetchOpts:{ repo: "insert-helm-chart-repository-url-here", // Specify the Helm repository URL }, }, { provider }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig;

    Detailed explanation:

    • We start by importing the required packages: @pulumi/pulumi for the Pulumi engine itself, @pulumi/awsx and @pulumi/eks for creating AWS resources including the EKS cluster, and @pulumi/kubernetes for managing Kubernetes resources like the Helm chart.

    • eks.Cluster: This creates our EKS cluster with defaults that are suitable for many use cases.

    • k8s.Provider: This tells Pulumi how to communicate with the Kubernetes cluster by using the kubeconfig that the EKS cluster resource outputs.

    • k8s.helm.v3.Chart: This deploys the Helm chart representing the Medusa application. Note that you will need to replace "insert-chart-version-here" with the actual chart version you wish to deploy, and "insert-helm-chart-repository-url-here" with the Helm repository URL where the Medusa chart is located.

    • kubeconfig: We export the kubeconfig so you can interact with your Kubernetes cluster using kubectl or other Kubernetes tools.

    You need to replace placeholders with actual values pertinent to the Medusa Helm chart you wish to deploy. This program will create a new EKS cluster and deploy the specified Helm chart to that cluster. After running this Pulumi program, you will have a running instance of the Medusa application on AWS EKS.
