Overview of this book

Kubernetes has emerged as the de facto standard for container orchestration, with recent developments making it easy to deploy and handle a Kubernetes cluster. However, a few challenges such as networking, load balancing, monitoring, and security remain. To address these issues, Amazon EKS offers a managed Kubernetes service to improve the performance, scalability, reliability, and availability of AWS infrastructure and integrate with AWS networking and security services with ease. You’ll begin by exploring the fundamentals of Docker, Kubernetes, Amazon EKS, and its architecture along with different ways to set up EKS. Next, you’ll find out how to manage Amazon EKS, encompassing security, cluster authentication, networking, and cluster version upgrades. As you advance, you’ll discover best practices and learn to deploy applications on Amazon EKS through different use cases, including pushing images to ECR and setting up storage and load balancing. With the help of several actionable practices and scenarios, you’ll gain the know-how to resolve scaling and monitoring issues. Finally, you will overcome the challenges in EKS by developing the right skill set to troubleshoot common issues with the right logic. By the end of this Kubernetes book, you’ll be able to effectively manage your own Kubernetes clusters and other components on AWS.

Deploying a sample Kubernetes application with Helm

In the previous chapter, we deployed the NGINX ingress controller using the following command:

$ kubectl create -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/I

If we want to install it using Helm, we need to perform the following tasks:

  1. Add the public stable repository to your Helm configuration:
    $ helm repo add nginx-stable https://helm.nginx.com/stable
  2. Refresh the repository information:
    $ helm repo update
  3. We can then show the charts in the repository:
    $ helm search repo nginx-stable
  4. One of the charts will be nginx-ingress, which can be installed using the following command:
    $ helm install my-release nginx-stable/nginx-ingress
  5. The chart release can be viewed using either of these commands:
    $ helm list
    $ helm history my-release
  6. You can also view the Kubernetes resources using the following command:
    $ kubectl api-resources --verbs=list -o name | xargs -n 1 kubectl get --show-kind -l app...
