1. Deploy the alert-stream-simulator helm chart on AWS EKS


    To deploy the alert-stream-simulator Helm chart on AWS EKS using Pulumi, you would first need to create an EKS cluster. Once the cluster is ready, you would use the Pulumi Kubernetes provider to deploy the Helm chart to that cluster.

    Below is a program that accomplishes this. It is written in TypeScript and designed to be used with Pulumi. The program is split into two main parts:

    1. EKS Cluster Creation: Creates an Amazon EKS cluster using the @pulumi/eks package, which is a high-level package that simplifies EKS cluster deployments.

    2. Helm Chart Deployment: Deploys the alert-stream-simulator Helm chart to the EKS cluster using Pulumi's @pulumi/kubernetes package.

    Here's a step-by-step explanation of what we're going to do:

    • Import the necessary Pulumi packages.
    • Create a new EKS cluster.
    • Define the alert-stream-simulator Helm chart using Pulumi's Kubernetes provider.
    • Export relevant data such as the EKS cluster's kubeconfig.

    Before starting, make sure you've set up your AWS and Pulumi accounts and have installed the Pulumi CLI. You should have AWS credentials configured on your system for Pulumi to access your AWS account.

    Now, let's dive into the Pulumi 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 a VPC for our cluster. const vpc = new awsx.ec2.Vpc("my-vpc", {}); // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", { vpcId: vpc.id, subnetIds: vpc.subnets.public.map(it => it.id), }); // Create a Kubernetes provider instance that uses our EKS cluster. const k8sProvider = new k8s.Provider("k8s", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the alert-stream-simulator Helm chart. const alertStreamSimulatorChart = new k8s.helm.v3.Chart("alert-stream-simulator", { chart: "alert-stream-simulator", // You need to specify the correct chart repo here if it's not part of the default Helm chart repositories. // You may also need to specify chart version and any custom values. }, { provider: k8sProvider }); // Export the EKS cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig;

    In this program:

    • We use awsx to create a new VPC, which is required by EKS.
    • We use eks to create a new EKS cluster which auto-generates a kubeconfig. The subnetIds option specifies that we want our EKS cluster to operate in the VPC's public subnets.
    • We set up a Pulumi Kubernetes provider, k8s.Provider, with the generated kubeconfig. This provider is then used for deploying the Helm chart.
    • We deploy a Helm chart named alert-stream-simulator. This assumes that the Helm chart is available in a Helm repo that has already been added to your Helm environment. If it's in a custom repo, you need to specify the repo attribute in the chart's arguments.
    • We then export the kubeconfig of the created cluster. This allows us to interact with the Kubernetes cluster using tools like kubectl.

    After writing this Pulumi code, you would run pulumi up to provision the resources. Make sure to review the execution plan Pulumi provides before confirming you want to proceed with the deployment.
