1. Deploy the prometheus-federation helm chart on AWS EKS

    TypeScript

    To deploy the Prometheus Federation Helm chart on AWS EKS, we will carry out the following steps:

    1. Create an EKS cluster on AWS using aws.eks.Cluster which will be our Kubernetes environment.
    2. Create an IAM role for EKS with the required policies using aws-iam.EKSRole.
    3. Deploy the Prometheus Federation Helm chart on the EKS cluster, using kubernetes.helm.v3.Chart.

    Here's how we can define our Pulumi program in TypeScript:

    import * as aws from '@pulumi/aws'; import * as awsx from '@pulumi/awsx'; import * as eks from '@pulumi/eks'; import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create an EKS cluster const cluster = new eks.Cluster("eksCluster", { // Define the desired version for your EKS cluster. version: "1.21", // Specify additional settings like VPC configuration, IAM roles, etc., as needed. }); // Step 2: Create an IAM Role for EKS const eksRole = new aws.iam.Role("eksRole", { assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal(aws.iam.Principals.EksPrincipal), }); const servicePolicyAttachment = new aws.iam.RolePolicyAttachment("eks-service-policy", { role: eksRole, policyArn: aws.iam.ManagedPolicies.AmazonEKSServicePolicy, }); const clusterPolicyAttachment = new aws.iam.RolePolicyAttachment("eks-cluster-policy", { role: eksRole, policyArn: aws.iam.ManagedPolicies.AmazonEKSClusterPolicy, }); // Step 3: Deploy the Helm chart for Prometheus Federation to the EKS cluster const prometheusFederationChart = new k8s.helm.v3.Chart("prometheusFederation", { chart: "prometheus-federation", // The version of the Helm chart. Make sure to specify a version to prevent updates from inadvertently // being applied when the chart is updated in the repository. version: "x.y.z", // Replace with the actual chart version namespace: "monitoring", // Specify the namespace for deployment, this needs to be created if not already present. fetchOpts:{ // Define repository options, like the repository URL, if it's not a part of the default Helm repo list. repo: "https://prometheus-community.github.io/helm-charts", }, // Set values to configure your Prometheus Federation setup. values: { // Define values for chart configurations like resource limits, affinity, annotations etc. }, }, { provider: cluster.provider, // This ensures that Helm chart is installed on the created EKS cluster. }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeconfig;

    Each step is marked with comments to guide you through what each section is doing. Here's an overview of the Pulumi resources used in the above program:

    • eks.Cluster: This creates the AWS EKS cluster where your Kubernetes resources will run.
    • aws.iam.Role and aws.iam.RolePolicyAttachment: These create an IAM role and attach the necessary policies to allow the EKS service to manage resources on your behalf.
    • k8s.helm.v3.Chart: This represents a Helm chart, which in this scenario deploys the Prometheus Federation chart to your cluster.

    Please replace "x.y.z" with the actual version of the Prometheus Federation Helm chart you intend to deploy.

    Lastly, we export the kubeconfig of the cluster so you can interact with your Kubernetes cluster using kubectl or other Kubernetes tools after deployment.

    To apply this Pulumi program:

    1. Save the above code to a file named index.ts.
    2. Run pulumi up to preview and deploy the changes. Ensure you have authenticated with both Pulumi and AWS.
    3. After the deployment is successful, the output will display the generated kubeconfig. You can use this to interact with your newly created EKS Kubernetes cluster.

    Make sure to review AWS EKS, AWS IAM Role, and Helm Chart in the Pulumi Registry for more details on configurable properties and usage.
