Kubernetes on AWS

Overview of this book

Docker containers promise to radicalize the way developers and operations build, deploy, and manage applications running on the cloud. Kubernetes provides the orchestration tools you need to realize that promise in production. Kubernetes on AWS guides you in deploying a production-ready Kubernetes cluster on the AWS platform. You will then discover how to utilize the power of Kubernetes, which is one of the fastest growing platforms for production-based container orchestration, to manage and update your applications. Kubernetes is becoming the go-to choice for production-grade deployments of cloud-native applications. This book covers Kubernetes from first principles. You will start by learning about Kubernetes' powerful abstractions - Pods and Services - that make managing container deployments easy. This will be followed by a guided tour through setting up a production-ready Kubernetes cluster on AWS, while learning the techniques you need to successfully deploy and manage your own applications. By the end of the book, you will have gained plenty of hands-on experience with Kubernetes on Amazon Web Services. You will also have picked up some tips on deploying and managing applications, keeping your cluster and applications secure, and ensuring that your whole system is reliable and resilient to failure.

Summary

By now, you should have a basic understanding of the stack of software that makes a modern container orchestrator like Kubernetes tick.

You should now understand the following:

  • Containers are built on top of much lower-level features in the Linux kernel, such as namespaces and Cgroups.
  • In Kubernetes a pod is a powerful abstraction that is built on top of containers.
  • Kubernetes uses control loops to build a powerful system that allows the operator to declaratively specify what should be running. Kubernetes automatically takes actions to drive the system towards this state. This is the source of Kubernetes' self-healing properties.
  • Nearly everything in Kubernetes can be given a label, and you should label your resources in order to make managing them simpler.

In the next chapter, you will gain some practical experience using the Kubernetes APIs by running a small cluster on your workstation.
