1. Deploy the spot-scheduler helm chart on AWS EKS


    To deploy the spot-scheduler Helm chart on AWS EKS, you will need to follow these steps:

    1. Create an EKS cluster using the aws.eks.Cluster resource.
    2. Deploy the spot-scheduler Helm chart using the kubernetes.helm.v3.Chart resource.

    I will explain each step and the corresponding code.

    Step 1: Create an EKS Cluster

    First, you define an EKS cluster. This will be the Kubernetes cluster in which your spot-scheduler will run. To create an EKS cluster, you will specify a name for the cluster, the EKS role ARN, a specific Kubernetes version, and the VPC configuration that includes the VPC ID and subnet IDs.

    The awsx.eks.Cluster resource is a high-level component that abstracts away a lot of the complexity of setting up an EKS cluster. It automatically creates and manages the underlying AWS resources such as the EKS cluster, node groups, and other networking resources.

    Step 2: Deploy the Helm Chart

    After the EKS cluster is up and running, you can deploy the spot-scheduler Helm chart. The kubernetes.helm.v3.Chart resource is used to deploy applications packaged as Helm charts on your Kubernetes cluster. You will specify the chart name, optionally the version, and the set of configurable values for the Helm chart.

    Below you'll find a Pulumi program in TypeScript that accomplishes these steps. This program assumes you have AWS credentials configured for Pulumi to use and kubectl installed and configured to interact with EKS clusters.

    import * as awsx from '@pulumi/awsx'; import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Create an EKS cluster. const cluster = new awsx.eks.Cluster('my-cluster', { // Specify the desired Kubernetes version for your EKS cluster version: '1.21', // Other optional configuration options may include role permissions, // VPC and subnet IDs for your worker nodes, etc. }); // The code for Helm chart deployment will go here. // Export the kubeconfig to access the cluster. export const kubeconfig = cluster.kubeconfig; // Inside the `create` callback, you can interact with the cluster. cluster.create(async () => { // Provide the configuration for the Helm chart deployment const spotSchedulerChart = new k8s.helm.v3.Chart('spot-scheduler', { chart: 'spot-scheduler', version: '1.0.0', // Specify the chart version you wish to deploy fetchOpts: { repo: 'https://charts.example.com/', // Replace with the actual Helm chart repository }, // If there are any configurable values for the spot-scheduler chart you wish to override, // specify them here values: { /* ... */ }, }, { provider: cluster.provider }); // You can place further k8s resources or Helm charts to deploy here. });

    This program creates an EKS cluster and deploys the spot-scheduler Helm chart to it. Make sure to replace 'https://charts.example.com/' with the actual repository URL where the spot-scheduler Helm chart is hosted.

    The kubeconfig export provides the necessary details to connect to your EKS cluster with kubectl. You can grab these details from the stack output after deploying this Pulumi program.

    For additional information, here are some relevant parts of the Pulumi documentation:

    Please note that this code serves as a base foundation, and you might need to adjust it according to your specific use case — particularly the Helm chart's configurable values and the EKS cluster's configuration parameters.
