1. Deploy the redisoperator helm chart on AWS EKS


    To deploy the redisoperator Helm chart on AWS Elastic Kubernetes Service (EKS), you'll need to create an EKS cluster, get the Helm chart, and deploy it to the cluster. Below is an overview of the steps you'll be taking in the Pulumi TypeScript program:

    1. Create an EKS Cluster: Using Pulumi's EKS package, we will instantiate a managed Kubernetes cluster. The eks.Cluster class will help create and configure an EKS cluster with sensible defaults.

    2. Deploy Helm Chart to EKS: After the cluster is up and running, we use Pulumi's kubernetes.helm.v3.Chart resource to deploy the redisoperator Helm chart onto the EKS cluster. This resource can install, manage, and uninstall Helm charts in a Kubernetes cluster.

    Below is a Pulumi program written in TypeScript that fulfills your goal:

    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-cluster", { // Specify the desired number of cluster nodes. desiredCapacity: 2, minSize: 1, maxSize: 3, // Specify the instance type to use for the cluster nodes. instanceType: "t2.medium", }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Create a Kubernetes provider instance that uses our EKS cluster. const provider = new k8s.Provider("my-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the redisoperator Helm chart to the EKS cluster. const redisOperatorChart = new k8s.helm.v3.Chart("redis-operator", { chart: "redis-operator", version: "X.Y.Z", // Replace X.Y.Z with the latest chart version fetchOpts: { repo: "https://charts.bitnami.com/bitnami", }, }, { provider }); // Export the Redis operator status export const redisOperatorStatus = redisOperatorChart.status;

    Here's an explanation of the code:

    • EKS Cluster: The eks.Cluster class is creating a Kubernetes cluster in AWS EKS. It takes parameters to configure the number of nodes (desiredCapacity, minSize, and maxSize), the type of instance (instanceType), and others. Related documentation for this resource can be found here.

    • Kubeconfig: The output kubeconfig is the configuration needed to connect to the cluster with kubectl and other tools. This is exported so that you can easily access your cluster from outside Pulumi.

    • Kubernetes Provider: The k8s.Provider resource points to our EKS cluster. It uses the kubeconfig from the EKS cluster which allows Pulumi to deploy Kubernetes resources to that cluster.

    • Helm Chart: The k8s.helm.v3.Chart class represents a Helm chart. In this case, it is used to deploy redis-operator. You'll need to replace X.Y.Z with the version number of the chart you wish to deploy. The fetchOpts.repo specifies the Helm repository URL where the chart is located. It's important to change the chart, version, and repo values based on the actual Helm chart details you want to deploy. The documentation for using Helm charts with Pulumi can be found here.

    • Redis Operator Status: Exporting the redisOperatorChart.status allows you to retrieve the deployment status of the Redis operator Helm chart. This way you can monitor when the chart has been successfully deployed.

    Please replace the placeholders, like the version number, with actual values appropriate for your deployment. Also, set up your AWS credentials and Pulumi configuration before running this program.
