Kubernetes on AWS

By: Ed Robinson

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

Kubernetes is a powerful tool; it is very effective at achieving much higher usage of compute resources than would ever be possible by manually scheduling applications to machines. It is important that you learn how to allocate resources to your pods by setting the correct resource limits and requests; if you don't, your applications can become unreliable or starved of resources.

By understanding how Kubernetes assigns Quality of Service classes to your pods based on the resource requests and limits that you assign them, you can have precisely control how your pods are managed. By ensuring your critical applications, such as web servers and databases, run with the Guaranteed class, you can ensure that they will perform consistently and suffer minimal disruption when pods need to be rescheduled. You can improve the efficiency of your cluster by setting limits on lower...
