1. Deploy the simple-grafana helm chart on AWS EKS


    In order to deploy the simple-grafana Helm chart on AWS Elastic Kubernetes Service (EKS), we’ll go through several steps:

    1. Setup an EKS Cluster: We'll create an EKS cluster where our Grafana Helm chart will be deployed. This requires creating the necessary roles and VPC configuration.

    2. Create an ECR Repository (optional): If you need to manage container images, you might optionally want to set up an Elastic Container Registry (ECR) repository. This, however, isn't directly required for deploying a standard Helm chart.

    3. Deploy the Helm Chart: Once our Kubernetes cluster is ready, we will deploy the simple-grafana Helm chart to the EKS cluster.

    I’ll provide a TypeScript program for Pulumi which you can use to deploy the simple-grafana Helm chart on an AWS EKS cluster. The program will include comments to explain the steps.

    Let’s start building this out.

    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', { version: '1.18', // Specify your desired Kubernetes version here instanceType: 't2.medium', // Specify your desired instance type here desiredCapacity: 2, // Specify the number of worker nodes minSize: 1, maxSize: 3, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Deploy the simple-grafana Helm chart to the EKS cluster const grafanaChart = new k8s.helm.v3.Chart('simple-grafana', { repo: 'grafana', // Ensure this is the correct Helm repo for simple-grafana chart: 'grafana', version: '6.1.9', // Specify your desired chart version here namespace: 'default', // Specify the namespace if you're not using the default one }, { provider: cluster.provider }); // Export the Grafana service URL by querying the service object and finding its load balancer URL export const grafanaUrl = grafanaChart.getResourceProperty('v1/Service', 'simple-grafana', 'status') .apply(status => status.loadBalancer.ingress[0].hostname);

    This is the basic structure of how you could use Pulumi and TypeScript to create an EKS cluster and deploy the simple-grafana Helm chart onto it.

    Here's what each piece of the code does:

    • eks.Cluster: Provisions a new EKS cluster with the specified Kubernetes version, instance type, and scaling parameters.

      • The version is the desired Kubernetes version.
      • The instanceType is the AWS EC2 instance type for your worker nodes.
      • desiredCapacity, minSize, maxSize control the scaling of your worker nodes.
      • The kubeconfig output allows you to interact with your cluster using tools like kubectl.
    • k8s.helm.v3.Chart: Deploys a Helm chart onto the Kubernetes cluster.

      • The repo, chart, and version parameters specify the details of the Helm chart you want to deploy.
      • Set provider: cluster.provider to ensure the Helm chart is installed on the newly created EKS cluster.
    • grafanaUrl: Exports the URL on which Grafana can be reached after it has been deployed.

    Make sure you have the Pulumi CLI installed and are logged in to the AWS console with appropriate permissions. You would run this script using the Pulumi CLI, and it would handle the creation and deployment of these resources for you.

    Remember that deploying real infrastructure may incur costs in AWS. Always review the resources and understand the billing implications before deployment.
