Launching An EKS Cluster With eksctl

Elastic Kubernetes Service (EKS) is a fully managed Kubernetes service from AWS. In this lab, you will work with the AWS command-line interface and console, using command-line utilities like `eksctl` and `kubectl` to launch an EKS cluster, provision a Kubernetes Deployment and Pod running instances of `nginx`, and create a `LoadBalancer` Service to expose your application over the internet.

  1. Challenge

    Log In to the Provided EC2 Instance

    Log in to the EC2 instance provided in the lab environment using the public IP address, cloud_user username, and password provided in the lab interface.

  2. Challenge

    Provision an EKS Cluster

    Use eksctl to provision an EKS cluster with three worker nodes in us-east-1. Use Kubernetes version 1.16 or later.

  3. Challenge

    Create a Deployment on Your EKS Cluster

    Using kubectl and the provided Service and Deployment definition files provided in the EKS Basics GitHub repository:

    • Create a LoadBalancer Service.
    • Check the status of your LoadBalancer Service using kubectl.
    • Create an NGINX Deployment.
    • Check the status of your cluster, Deployment, and Pods using kubectl.
    • When NGINX is up and running, check that you can access your application using the DNS name of the LoadBalancerprovided in the kubectl get service output.

  4. Challenge

    Test the High Availability Features of Your EKS Cluster

    1. In the EC2 console, terminate all the worker nodes.
    2. Check the status of your cluster, Deployment, and Pods using kubectl. After a few minutes, you should see EKS launching new instances to keep your Service running.
    3. When the cluster is back to a steady state, check that your application is up and running using curl.
