1. Deploy the clusternet-controller-manager helm chart on AWS EKS

    TypeScript

    To deploy the clusternet-controller-manager helm chart on AWS EKS using Pulumi, we are going to undertake the following steps:

    1. Create an EKS Cluster: First, we'll set up an Amazon EKS cluster using the eks.Cluster component in Pulumi which provides a simplified way to instantiate an EKS cluster, manage its Kubernetes worker nodes, and configure the Kubernetes resources.

    2. Deploy the Helm Chart: Once we have an EKS cluster up and running, we'll deploy the clusternet-controller-manager helm chart using the kubernetes.helm.v3.Chart resource provided by Pulumi. This resource allows us to deploy Helm charts within a Kubernetes cluster.

    To accomplish this, we need to write a Pulumi program in TypeScript, which assumes that you have the necessary AWS and Pulumi credentials configured in your environment.

    Here is a program that will set up an EKS cluster and deploy the clusternet-controller-manager helm chart on it:

    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", { desiredCapacity: 2, // Number of worker nodes minSize: 1, maxSize: 3, instanceType: "t2.medium", // Instance type for the worker nodes // Other configuration options for the cluster... }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Set up the Kubernetes provider to use the kubeconfig from the EKS cluster for subsequent resources. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the clusternet-controller-manager helm chart. const clusternetChart = new k8s.helm.v3.Chart("clusternet-controller-manager", { chart: "clusternet-controller-manager", version: "0.1.0", // Use the appropriate chart version fetchOpts: { repo: "http://charts.clusternet.io", // Replace with the correct chart repository }, }, { provider: k8sProvider }); // Make sure to pass the k8s provider we set up earlier based on the EKS cluster's kubeconfig // Export any necessary outputs. // For example, you could export the Helm chart's status or any other data you would need. export const clusternetChartStatus = clusternetChart.status;

    Explanation

    • We begin by importing the necessary Pulumi packages, such as @pulumi/pulumi, @pulumi/aws, @pulumi/eks, and @pulumi/kubernetes.
    • We then create an EKS cluster by initializing a new eks.Cluster object. This step creates a VPC, security groups, an IAM role, and then deploys an AWS EKS cluster with default settings. You can modify the number of worker nodes, instance type, and other configuration options as needed.
    • We export the EKS cluster's kubeconfig which allows you to interface with your cluster using kubectl or other Kubernetes tools.
    • Next, we set up a Kubernetes provider that uses the kubeconfig from our EKS cluster to manage Kubernetes resources.
    • Afterward, we use k8s.helm.v3.Chart to deploy the clusternet-controller-manager helm chart. Note that you need to replace "0.1.0" and the repo URL with the correct version and chart repository URL for clusternet-controller-manager.
    • Lastly, we export the Helm chart's status as an output, which could be used for debugging or automation purposes.

    Remember to replace placeholders like the instance type, chart version, and chart repository with actual values that align with your intended deployment. Do not forget to install the clusternet chart only after the EKS cluster is up and running, as it requires a Kubernetes cluster to deploy to.
