1. Deploy the ceph helm chart on AWS EKS


    Deploying a Ceph Helm chart on AWS EKS with Pulumi involves several steps. First, you need to create an EKS cluster, and then deploy the Helm chart onto that cluster. For the purpose of deploying the Helm chart, you'll require access to a Kubernetes kubeconfig file that allows you to interact with the EKS cluster.

    Here's an overview of the process:

    1. Create EKS Cluster: Using eks.Cluster which simplifies creating an EKS cluster and its dependencies (EKS Cluster Documentation).
    2. Setup Helm Release: You will also use the helm.v3.Release resource class from @pulumi/kubernetes which allows you to deploy Helm charts in a Pulumi program (Helm Release Documentation).

    Below is a comprehensive Pulumi TypeScript program that will:

    • Create an EKS cluster
    • Install the Ceph Helm chart onto the cluster

    Please make sure you have Pulumi installed and configured for AWS access.

    import * as eks from "@pulumi/eks"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create a VPC for our cluster. const vpc = new eks.Cluster("myCluster"); // Export the VPC's kubeconfig. export const kubeconfig = vpc.kubeconfig; // Create an instance of the Kubernetes Provider using the kubeconfig from the EKS cluster. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: vpc.kubeconfig.apply(JSON.stringify), }); // Deploy the Ceph Helm chart. const cephChart = new k8s.helm.v3.Chart("ceph", { chart: "ceph", version: "x.x.x", // Replace with the desired chart version fetchOpts: { repo: "https://helm.ceph.com/", // Replace with the Ceph Helm chart repo if different }, }, { provider: k8sProvider }); // Export any desired outputs from the Helm chart. export const cephEndpoints = cephChart.getResourceProperty('v1/Service', 'ceph', 'spec').apply(spec => spec.clusterIP);


    • eks.Cluster: This class creates a managed EKS cluster. It will configure the necessary AWS resources such as the VPC, subnets, and the EKS cluster itself. The output kubeconfig is used to communicate with the Kubernetes cluster.

    • k8s.Provider: This class provides a way for Pulumi to communicate with the Kubernetes API server. It uses the kubeconfig output from the eks.Cluster to establish this communication.

    • k8s.helm.v3.Chart: This Pulumi resource is used to deploy Helm charts into the Kubernetes cluster. The chart parameter specifies the name of the Helm chart, the version specifies the specific chart version to install, and the fetchOpts is used for defining the Helm repository URL.

    Before running this program with Pulumi (pulumi up), you may need to install the @pulumi/eks and @pulumi/kubernetes libraries using npm if you haven't already:

    npm install @pulumi/eks @pulumi/kubernetes

    After initializing your Pulumi project, running the pulumi up command in the directory containing this code will create the AWS EKS cluster and deploy the Ceph Helm chart defined in the program.

    Always make sure to use appropriate versions and configurations that are compatible with your environment and requirements.
