1. Deploy the k8s-spot-rescheduler helm chart on AWS EKS


    To deploy the k8s-spot-rescheduler Helm chart on AWS EKS (Elastic Kubernetes Service), you will need to follow these general steps:

    1. Create an EKS cluster on AWS: This will be the Kubernetes environment where your applications will run.
    2. Deploy the Helm chart to the EKS cluster: Helm is a package manager for Kubernetes that allows you to deploy applications defined in Helm charts.

    First, you need to set up an EKS cluster. The following Pulumi program will create a basic EKS cluster using the eks package, which is a high-level component that simplifies deploying and managing EKS clusters. It automatically handles the necessary roles, security groups, and other infrastructure items that EKS requires.

    After creating the cluster, you'll use the kubernetes package to deploy the k8s-spot-rescheduler Helm chart to your EKS cluster. Note that you will need to have kubectl configured to communicate with your EKS cluster for this to work, which can be done automatically by the Pulumi eks.Cluster output.

    Below is a detailed TypeScript Pulumi program that sets up an EKS cluster and deploys the k8s-spot-rescheduler Helm chart:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create an EKS cluster with the default configuration. const cluster = new eks.Cluster("my-cluster", { desiredCapacity: 2, minSize: 1, maxSize: 3, storageClasses: "gp2", deployDashboard: false, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Use the EKS cluster's kubeconfig to create a provider. const provider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the k8s-spot-rescheduler Helm chart using the created provider. const spotReschedulerChart = new k8s.helm.v3.Chart("k8s-spot-rescheduler", { chart: "k8s-spot-rescheduler", version: "<chart version>", // replace with the desired chart version fetchOpts: { repo: "https://charts.example.com/", // replace with the Helm chart repository URL }, }, { provider }); // Export the deployment name of the spot-rescheduler. export const spotReschedulerName = spotReschedulerChart.getResourceProperty("v1/Deployment", "k8s-spot-rescheduler", "metadata", "name");

    This Pulumi program does the following:

    • Defines a new EKS cluster with the desired configuration for size and storage.
    • Exports the kubeconfig necessary to interact with the EKS cluster using kubectl.
    • Creates a Pulumi Kubernetes provider using the exported kubeconfig of the EKS cluster.
    • Deploys the k8s-spot-rescheduler Helm chart to the EKS cluster using the aforementioned Kubernetes provider.

    To prepare for running this program, you should have the following prerequisites:

    • Pulumi CLI installed and configured.
    • AWS CLI installed and configured with appropriate credentials.
    • Kubernetes CLI (kubectl) installed.
    • Helm CLI (if you need to customize or inspect the Helm chart before deployment).

    Once the program is ready, you run it using Pulumi CLI with pulumi up, which will execute the deployment. After successful deployment, the k8s-spot-rescheduler Helm chart will be running on your EKS cluster, and Kubernetes workloads on spot instances will have the appropriate scheduling support based on the configuration provided in the Helm chart.
