1. Deploy the flask-note helm chart on AWS EKS


    To deploy the flask-note Helm chart on AWS Elastic Kubernetes Service (EKS), you will need to follow these steps:

    1. Set up an EKS cluster: Use the Pulumi EKS package to create and configure your EKS cluster appropriately.
    2. Deploy the Helm chart: Use the Pulumi Kubernetes provider to deploy the flask-note Helm chart to your EKS cluster.

    We'll create a Pulumi program in TypeScript, which will include:

    • Creating an EKS cluster with all necessary configurations.
    • Deploying the flask-note Helm chart to the EKS cluster.

    EKS Cluster Creation

    We start by creating an EKS cluster. This involves creating a VPC (or specifying an existing one), defining subnets, and setting up the necessary IAM roles for EKS. We will use the high-level eks.Cluster resource, which simplifies this process.

    Helm Chart Deployment

    After setting up the EKS cluster, we will deploy the Helm chart. The chart should be available in a Helm repository or a local path. For illustration purposes, I'll assume you have added the chart to a Helm repository.

    Here's the Pulumi program that accomplishes these steps:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster with the default configuration const cluster = new eks.Cluster("flask-note-cluster", {}); // Create a Kubernetes provider instance using the kubeconfig from the EKS cluster const k8sProvider = new k8s.Provider("flask-note-k8sProvider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy the flask-note helm chart to the EKS cluster const flaskNoteChart = new k8s.helm.v3.Chart("flask-note-chart", { chart: "flask-note", version: "1.0.0", // replace with the actual chart version fetchOpts: { repo: "http://your-helm-chart-repository", // replace with the actual Helm chart repository URL }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the Helm chart deployment status export const kubeconfig = cluster.kubeconfig; export const chartStatus = flaskNoteChart.status;

    Detailed Explanation:

    • @pulumi/eks is the Pulumi EKS package that handles the creation of EKS clusters easily.
    • eks.Cluster allows us to create an EKS cluster. It abstracts away many of the underlying resources needed and provides sane defaults.
    • @pulumi/kubernetes is the Pulumi Kubernetes provider that allows us to interact with the cluster, including deploying Helm charts.
    • k8s.Provider is used to create a Kubernetes provider object. This allows Pulumi to communicate with the EKS cluster we've created to deploy applications.
    • k8s.helm.v3.Chart represents a Helm chart for deployment, which we're using to deploy the flask-note application onto our EKS cluster.

    Follow-up Steps:

    After deploying this Pulumi program with pulumi up, Pulumi will output the kubeconfig needed to interact with your EKS cluster directly via kubectl or other Kubernetes tooling.

    Your flask-note application should now be running on an AWS EKS cluster! You can verify its presence by using the Kubernetes tools (kubectl) to check the deployed services, pods, and more within the specified namespace of the Helm chart release.

    Remember to check the official Pulumi EKS documentation and Pulumi Kubernetes documentation for more details on using EKS and Kubernetes with Pulumi.
