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.

Summary

In this chapter, we examined the different ways you can deploy applications, starting with creating a simple Pod and building on top of this concept with deployments, services, an Ingress, and finally deploying an AWS NLB and NGINX Ingress controller to expose the service to the internet. We discussed how a Deployment and Service can provide greater resilience and abstraction on top of a Pod and how services, Ingresses, and load balancers can be used to expose a service in a secure/resilient manner outside of the cluster/VPC.

Throughout this chapter, we used a Kubernetes YAML manifest to illustrate how to build and deploy these objects using kubectl. You now have the ability to deploy applications in EKS using the basic YAML manifests and kubectl. In the next chapter, we will look at how Helm can be used to create flexible manifests that can be parametrized at deployment time to support different requirements and/or environments.
