1. Deploy the hadoop-yarn helm chart on AWS EKS


    To deploy the Hadoop-YARN Helm chart on an Amazon EKS cluster using Pulumi, you'll need to perform a few steps:

    1. Create an EKS cluster on AWS.
    2. Deploy the Hadoop-YARN Helm chart on the cluster.

    I'll provide you with a Pulumi program that accomplishes this. The program will first define the EKS cluster and then use the Helm chart resource from Pulumi's Kubernetes provider to deploy Hadoop-YARN.

    Here is a step-by-step walkthrough of what you'll do:

    1. We'll use the eks.Cluster class from the @pulumi/eks package to create an EKS cluster. This class abstracts away the complexity and allows for easy EKS cluster creation.

    2. Once the cluster is up and running, we'll obtain the required kubeconfig to interact with the cluster.

    3. Lastly, we'll use the kubernetes.helm.v3.Chart class from @pulumi/kubernetes to deploy the Hadoop-YARN chart from the Helm repository, with the configuration necessary for your cluster.

    Keep in mind you need to have pulumi, awscli, and kubectl installed and configured on your machine to run this program successfully. You should also have the necessary AWS credentials configured to create and manage EKS clusters.

    Now, here's the detailed Pulumi TypeScript program that creates the EKS cluster and deploys Hadoop-YARN using a Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as eks from "@pulumi/eks"; 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; // Create a Kubernetes provider instance that uses our cluster from above. const provider = new k8s.Provider("provider", { kubeconfig: cluster.kubeconfig, }); // Deploy Hadoop-YARN Helm chart using the Kubernetes provider. const hadoopChart = new k8s.helm.v3.Chart("hadoop-yarn", { repo: "stable", // Assuming the Helm chart is in the "stable" repository; replace with actual repo if different. chart: "hadoop", version: "1.0.0", // Replace with the desired chart version. namespace: "default", // Change accordingly if you wish to deploy in a different namespace. }, { provider }); // Export the Helm chart status export const helmChartStatus = hadoopChart.status;

    This program will perform the following actions:

    • It declares a new EKS cluster with default settings.
    • It exports the generated kubeconfig to enable kubectl to interact with the cluster.
    • It sets up a Kubernetes provider that points to the new EKS cluster.
    • It deploys the Hadoop-YARN Helm chart to the default namespace using the specified version and repository.

    You will need to replace stable with the actual repository where the Hadoop-YARN chart is hosted and 1.0.0 with the correct version of the chart you wish to install.

    Once you have this code in a TypeScript file (e.g., index.ts), you can run the following commands to preview and deploy your infrastructure:

    pulumi up

    This command will prompt you to review the infrastructure plan and confirm the deployment. After the deployment successfully completes, you will see the exported kubeconfig in the Pulumi stack outputs, which you can use with kubectl to manage your cluster.
