1. Deploy the nats-server helm chart on AWS EKS


    To deploy the nats-server Helm chart on AWS EKS using Pulumi, we'll need to perform several steps:

    1. Set up an EKS cluster: This involves creating an EKS cluster in AWS which will manage our Kubernetes workloads.
    2. Deploy the Helm chart: Once the cluster is ready, we will use Pulumi's Helm chart support to deploy nats-server onto the EKS cluster.

    We will be using the following Pulumi resources:

    Here is a Pulumi program in TypeScript that demonstrates how to do this:

    import * as eks from "@pulumi/eks"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", {}); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Once the EKS cluster is up and running, we can use the kubeconfig // to deploy the nats-server helm chart to the cluster. const natsChart = new k8s.helm.v3.Chart("nats", { chart: "nats", // You might need to specify a repository here if the nats Helm chart // isn't in the default Helm repository. // e.g., repo: "https://nats-io.github.io/k8s/helm/charts/", version: "0.8.0", // Use the correct version for nats-server Helm chart here. namespace: "default", // Specify the namespace if other than default. }, { provider: cluster.provider }); // Export the deployment name of the chart. export const helmDeploymentName = natsChart.urn;

    This program:

    • Initializes a new EKS cluster with a default configuration.
    • Deploys the nats-server Helm chart to the created EKS cluster using the Pulumi Kubernetes provider and the cluster's kubeconfig.
    • Exports the cluster's kubeconfig and the Helm deployment URN (Uniform Resource Name), which you can use to reference the deployment in further commands.

    Make sure you have the correct version of the nats-server Helm chart. You might also want to customize the Helm chart deployment with additional settings, which you can specify in the values property of the Helm chart resource.

    To run this Pulumi program, you will need to:

    • Install Pulumi and configure the AWS provider. You can find instructions here.
    • Place the code in a file called index.ts.
    • Run pulumi up to create the resources described above. The command will show you a preview and prompt you for confirmation before making any changes to your cloud resources.
    • Once applied, your EKS cluster and nats-server should be running in the specified AWS region.

    Remember to clean up resources with pulumi destroy when you're done to avoid unnecessary charges on your AWS account.
