1. Deploy the cvmfs helm chart on AWS EKS


    To deploy the CernVM-FS (cvmfs) Helm chart on AWS EKS (Elastic Kubernetes Service), we will proceed with the following steps:

    1. Set up an EKS cluster on AWS using the eks.Cluster component from Pulumi's EKS package, which simplifies creating and managing an EKS cluster.
    2. Once the EKS cluster is set up, we will deploy the cvmfs Helm chart using the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This resource lets us deploy Helm charts into a Kubernetes cluster.

    Before running the program, ensure that you have the following prerequisites in place:

    • Pulumi CLI installed.
    • AWS CLI installed and configured with the necessary permissions to create EKS clusters.
    • Kubernetes CLI (kubectl) installed to interact with the EKS cluster.
    • Helm CLI installed to manage Helm chart deployments (optional, as Pulumi can handle Helm charts directly).

    Below is a Pulumi TypeScript program that sets up an EKS Cluster and deploys the cvmfs Helm chart into it. Replace the chart values like namespace, repo, and chart with the appropriate details for the cvmfs Helm chart you want to deploy.

    import * as pulumi from '@pulumi/pulumi'; import * as eks from '@pulumi/eks'; import * as k8s from '@pulumi/kubernetes'; // Create a new EKS cluster. // The `eks.Cluster` is a high-level abstraction that wraps the creation of an EKS cluster. const cluster = new eks.Cluster('my-eks-cluster', { desiredCapacity: 2, minSize: 1, maxSize: 3, instanceType: 't2.medium', providerCredentialOpts: { profileName: 'your-aws-profile', // Replace with your AWS profile name }, }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Deploy the cvmfs Helm chart. // The `k8s.helm.v3.Chart` resource represents a single Helm chart deployment within a Kubernetes cluster. const cvmfsChart = new k8s.helm.v3.Chart('cvmfs', { chart: 'cvmfs', // Replace with the actual chart name. version: '1.0.0', // Specify the chart version you want to deploy. namespace: 'default', // Use the namespace where you want to deploy the chart. fetchOpts: { repo: 'https://kubernetes-charts.cern.ch', // Replace with the cvmfs chart repository. }, }, { provider: cluster.provider }); // At the end of the program, we simply export the `chart` property of the Helm deployment. // This gives us direct access to the deployment details if needed. export const chart = cvmfsChart.getResourceProperty('v1/Service', 'cvmfs', 'metadata');

    This program does the following:

    • Initializes a new EKS cluster with a specified node size and configuration.
    • Sets the AWS profile to use based on providerCredentialOpts. Replace 'your-aws-profile' with your actual AWS CLI profile name.
    • Deploys the cvmfs Helm Chart to the specified namespace within the created EKS cluster. Ensure that you replace 'https://kubernetes-charts.cern.ch' with the actual Helm repository URL for cvmfs.

    To apply this Pulumi program:

    1. Save the above code in a file named index.ts.
    2. Run pulumi up to preview and deploy the changes. Pulumi CLI will automatically handle the deployment process, provisioning all the necessary resources on AWS and then deploying the cvmfs Helm chart to the EKS cluster.

    Once the deployment is complete, you can interact with your EKS cluster using kubectl by setting the appropriate KUBECONFIG environment variable or directly through the pulumi stack output kubeconfig command, which will give you the kubeconfig output for your cluster.
