1. Deploy the datadog_helpers helm chart on AWS EKS


    To deploy the datadog_helpers Helm chart on an AWS EKS cluster using Pulumi, we need to follow these steps:

    1. Set up an EKS cluster using the aws.eks.Cluster resource.
    2. Install the Helm chart on the cluster using the kubernetes.helm.v3.Chart resource.

    Here's how you can do this with Pulumi in TypeScript:

    Setting Up the EKS Cluster

    First, we'll create an EKS cluster. We need an IAM role for the EKS cluster and a VPC configured appropriately for EKS. For this example, we'll assume an existing VPC is used, which will be identified by its ID.

    Installing Helm Chart onto the EKS Cluster

    After the cluster setup, we'll proceed to install the Helm chart. For that, we must configure Pulumi to use the Kubernetes provider to communicate with the EKS cluster we've set up.

    Here's the complete program:

    import * as pulumi from '@pulumi/pulumi'; import * as aws from '@pulumi/aws'; import * as eks from '@pulumi/eks'; import * as k8s from '@pulumi/kubernetes'; // Create an EKS cluster. const cluster = new eks.Cluster('my-eks-cluster', { // Specify the IAM role here // Assume an existing VPC vpcId: '<VPC-ID>', subnetIds: ['<SUBNET-ID-1>', '<SUBNET-ID-2>'], // replace with the actual subnet IDs instanceType: 't2.micro', // or any other desired instance type desiredCapacity: 2, minSize: 1, maxSize: 3, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Set up a Kubernetes provider using the EKS cluster's kubeconfig. const provider = new k8s.Provider('k8s-provider', { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the `datadog_helpers` Helm chart. const datadogHelpersChart = new k8s.helm.v3.Chart('datadog-helpers', { chart: 'datadog_helpers', // Specify repository if the helm chart is not in the stable repository. fetchOpts: { repo: 'https://<your-helm-chart-repo>' }, // replace with actual Helm chart repository URL // Specify the namespace if required, defaults to 'default' // namespace: '<namespace>', // Values to pass to the Helm chart. values: { // ... Provide actual values for the `datadog_helpers` chart }, }, { provider }); // Export the Helm chart name and version export const chartName = datadogHelpersChart.chart; export const chartVersion = datadogHelpersChart.version;


    • First, we've imported the necessary Pulumi packages which include AWS, EKS, Kubernetes, and the main Pulumi SDK.
    • Then, we are creating an EKS cluster in a given VPC and subnet(s). Make sure to replace <VPC-ID>, <SUBNET-ID-1>, and <SUBNET-ID-2> with the actual VPC and subnet IDs.
    • After defining the cluster, we export the kubeconfig which allows us to interact with the cluster through kubectl or any Kubernetes client.
    • We've created a Kubernetes provider pointing to the new EKS cluster; this provider is used to communicate with the Kubernetes API server.
    • Next, we've declared the Datadog Helpers Helm chart, specifying the chart name, optionally the repository URL if it's not a standard Helm repository, and any values that the chart requires.
    • We've exported the Helm chart name and version as outputs for easy reference.

    To run the program, you'll first need to have Pulumi installed and the AWS CLI configured. Then, you will place this code in a TypeScript file, e.g., index.ts, and run the following commands:

    pulumi up

    This will prompt Pulumi to perform the deployment according to the code above. The CLI will display the progress and any errors that might occur.

    If you're trying to deploy a chart that is not available in the public Helm chart repositories, remember to add the fetchOpts property to the Chart resource's argument object, specifying the URL where your chart can be found.

    Remember to replace placeholder values with actual ones from your AWS and Helm chart configurations.
