1. Deploy the yace-exporter helm chart on AWS EKS

    TypeScript

    Deploying the yace-exporter Helm chart on AWS EKS involves several steps. We will first need to set up an EKS cluster and then deploy the Helm chart onto it. To accomplish this, we'll use the Pulumi EKS package to create the cluster and the Pulumi Kubernetes package to deploy the Helm chart.

    Here is a step-by-step program written in TypeScript:

    1. Set up an EKS Cluster: We'll define an EKS cluster using the eks.Cluster class from Pulumi's EKS package. This will provision all the necessary AWS resources, including the EKS control plane and worker nodes.

    2. Deploy the Helm Chart: After the cluster is up and running, we'll deploy the yace-exporter chart using the Chart class from the Pulumi Kubernetes package. Helm charts are a great way to deploy and manage applications on Kubernetes.

    Below is the Pulumi program to deploy the yace-exporter on AWS EKS:

    import * as eks from "@pulumi/eks";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Create an EKS Cluster
const cluster = new eks.Cluster("my-cluster", {
    desiredCapacity: 2, // Desired number of worker nodes
    minSize: 1, // Minimum number of worker nodes
    maxSize: 3, // Maximum number of worker nodes
    // Other properties like instanceType, VPC configuration, etc., can be set here
});

// Export the Cluster's kubeconfig
export const kubeconfig = cluster.kubeconfig;

// Step 2: Deploy the yace-exporter Helm Chart onto the EKS cluster
const yaceExporterChart = new k8s.helm.v3.Chart("yace-exporter", {
    chart: "yace-exporter", // The name of the Helm chart
    version: "x.y.z", // Specify the version of the chart you want to deploy
    namespace: "monitoring", // Specify the namespace where the chart should be deployed
    fetchOpts: {
        repo: "http://path-to-your-helm-chart-repository/", // URL to the Helm repository
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig }) });

// Export the Helm chart deployment status
export const yaceExporterDeploymentName = yaceExporterChart.getResourceProperty("v1/Service", "my-yace-exporter-service", "metadata").apply(m => m.name);

    Make sure to replace the "x.y.z" placeholder with the actual version of the yace-exporter Helm chart you wish to deploy, and "http://path-to-your-helm-chart-repository/" with the real URL of your chart's repository.

    Explanation:

    • EKS Cluster: The EKS cluster is created with a desired capacity of 2 worker nodes and is allowed to scale between 1 and 3 worker nodes to handle workload changes. Additional properties for the cluster can be specified according to your requirements.
    • kubeconfig: Exporting kubeconfig allows you to interact with your cluster using kubectl and other Kubernetes tooling outside of Pulumi.
    • Helm Chart: The yace-exporter Helm chart is deployed into the monitoring namespace on the EKS cluster. The fetchOpts.repo is where the Helm chart repository is located; it needs to be set to the location where your chart is hosted.
    • Kubernetes Provider: We create a new Kubernetes provider with the kubeconfig from the EKS cluster so that Pulumi knows where and how to deploy the Helm chart.

    To run this Pulumi program:

    • Save the code in a file with a .ts extension.
    • Run pulumi up to preview and deploy the changes.
    • Check the output for the exported kubeconfig and yaceExporterDeploymentName values.

    Make sure you have Pulumi installed and configured with the appropriate AWS credentials before running the program. If you are new to Pulumi, visit the Pulumi Get Started guide for AWS to set up your environment.
