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

Storing State

This chapter is all about utilizing the deep integration that Kubernetes has with the AWS native storage solution Elastic Block Store (EBS). Amazon EBS provides network attached storage as a service, and is the primary solution used to provide block storage to EC2 instances.

Nearly every EC2 instance launched is backed by an EBS root volume (created from an AMI machine image). Because EBS storage is network attached, if an underlying machine hosting an EC2 instance fails in some way, the data stored on the volume is safe as it is automatically replicated across multiple physical storage devices.

In addition to being used to store the root filesystem of EC2 instances, additional EBS volumes can be attached to EC2 instances and mounted on demand via the AWS API. Kubernetes integration with AWS EBS makes use of this to provide persistent volumes that can be used by...
