1. Deploy the pgbench helm chart on AWS EKS


    To deploy a pgbench Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster using Pulumi, we will follow these steps:

    1. Create an EKS cluster.
    2. Deploy the pgbench Helm chart to the EKS cluster.

    For step 1, we create an EKS cluster, which involves setting up the necessary AWS infrastructure, including specifying the VPC configuration and IAM role for the EKS cluster.

    For step 2, once the EKS cluster is running, we deploy the Helm chart by referencing it within our Pulumi program. We use the kubernetes.helm.v3.Chart resource, which allows us to deploy Helm charts into a Kubernetes cluster managed by our Pulumi program.

    pgbench is a benchmarking tool for PostgreSQL. To deploy it on EKS using a Helm chart, we first need to ensure there is a Helm chart available for pgbench. For this example, we'll assume such a chart is available in a known Helm repository.

    Below is a Pulumi program in TypeScript that illustrates these steps:

    import * as eks from '@pulumi/eks'; import * as kubernetes from '@pulumi/kubernetes'; // Create an EKS cluster. const cluster = new eks.Cluster('my-cluster', { // Specify the desired Kubernetes version version: '1.21', // Other properties like instance type, VPC configuration, IAM roles, etc. }); // Once the cluster is provisioned, we configure k8s provider to deploy Helm chart into the cluster. const provider = new kubernetes.Provider('k8s-provider', { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the pgbench Helm chart to the EKS cluster using the k8s provider. const pgbenchChart = new kubernetes.helm.v3.Chart('pgbench-chart', { // Referencing the chart from a known Helm repository. // Ensure the repo and chart exists or else pulumi up will fail. chart: 'pgbench', version: 'latest', // replace with a specific chart version fetchOpts: { // Assuming 'my-helm-repo' is the name of the Helm repo where pgbench exists. repo: 'https://charts.example.com/my-helm-repo', }, }, { provider }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig;

    In this program, we:

    • Import eks from @pulumi/eks, which simplifies creating an AWS EKS cluster.
    • Import kubernetes from @pulumi/kubernetes, which allows us to interact with Kubernetes resources.
    • Create an EKS cluster with a desired Kubernetes version and other configurations.
    • Set up a Kubernetes provider with the kubeconfig of the created EKS cluster.
    • Deploy the pgbench Helm chart into the cluster using the Kubernetes provider. Note that you should replace 'https://charts.example.com/my-helm-repo' with the actual URL of the Helm repository containing the pgbench chart.
    • Export the kubeconfig of the cluster for management purposes.

    To run this Pulumi program, save the above code to a file with a .ts extension, for example, index.ts. Be sure you have the AWS CLI configured with the necessary credentials, Pulumi CLI installed, and a Pulumi account set up to store your state information.

    Navigate to the program's directory in the terminal and then:

    • Run pulumi stack init to create a new stack.
    • Run pulumi up to execute the Pulumi program.

    This will provision your AWS EKS cluster and deploy the pgbench Helm chart to it. After completion, you'll receive the kubeconfig as an output that you can use to interact with your Kubernetes cluster, for example using kubectl.
