1. Deploy the ztncui helm chart on AWS EKS


    To deploy the ztncui Helm chart on AWS Elastic Kubernetes Service (EKS), we'll follow these steps:

    1. Set up an EKS cluster: We will create an Amazon EKS cluster, which is a managed Kubernetes service that simplifies running Kubernetes workloads without needing to install or maintain a Kubernetes control plane.
    2. Install the ztncui Helm chart: We'll deploy the ztncui application onto our EKS cluster using the Helm package manager for Kubernetes. Helm charts help define, install, and upgrade even the most complex Kubernetes applications.

    We'll use Pulumi's EKS package to create the EKS cluster and the Pulumi Kubernetes package to manage Helm charts.

    Here's the TypeScript program to perform the deployment:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. const cluster = new eks.Cluster("ztncui-cluster", { desiredCapacity: 2, // Desired number of worker nodes minSize: 1, // Minimum number of worker nodes maxSize: 3, // Maximum number of worker nodes instanceType: "t2.medium", // Instance size for worker nodes // ... other configurations such as VPC and IAM roles if needed }); // Once the cluster is created, we can get the kubeconfig for connecting to the cluster. const kubeconfig = cluster.kubeconfig.apply(JSON.stringify); // Create a Kubernetes provider using the kubeconfig from the EKS cluster. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the ztncui Helm chart onto the EKS cluster. const ztncuiChart = new k8s.helm.v3.Chart("ztncui", { chart: "ztncui", // Replace with the correct chart name if different version: "x.y.z", // Replace with the correct chart version // The repository containing the ztncui chart, this may need to be configured // with the Helm repository that houses the ztncui chart. fetchOpts: { repo: "https://helm-repository-containing-ztncui-chart.com", }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig. export const kubeconfigOutput = kubeconfig;


    • We first import the required Pulumi EKS and Kubernetes packages.
    • The eks.Cluster class is used to provision an EKS cluster. Here, you can specify the desired configuration, including the desired, minimum, and maximum size of the worker node group and the instance type for the worker nodes. You may need to configure additional settings such as VPC and IAM roles depending on your requirements.
    • The cluster.kubeconfig is a computed property that provides the kubeconfig file for connecting to the Kubernetes cluster. We apply JSON.stringify to it for proper serialization.
    • Using the kubeconfig, we create a Pulumi Kubernetes Provider, which allows us to interact with the EKS cluster.
    • With the k8s.helm.v3.Chart resource, we deploy the ztncui Helm chart to the EKS cluster. Specify the correct chart name and version, as well as the Helm repository URL where the ztncui chart is located. This might require you to first add the Helm repository to your local Helm setup.
    • We export the kubeconfig so that you can use it with kubectl to interact with your Kubernetes cluster directly, outside of Pulumi.

    Remember, before running this Pulumi program, you must have your AWS credentials configured and have Pulumi installed and configured with the correct context. Also, you should review the chart name, version, and repository values, replacing them with the correct information for the ztncui chart.
