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.

Pushing Docker images to ECR

Currently, the most commonly adopted way to store and deliver Docker images is through Docker Registry, an open source application by Docker that hosts Docker repositories. This application can be deployed on-premises, as well as used as a service from multiple providers, such as Docker Hub, Quay.io, and AWS ECR.

The application is a simple, stateless service, where most of the maintenance work involves making sure that storage is available, safe, and secure. As any seasoned system administrator knows, that is far from an easy ordeal, especially, if there is a large data store. For that reason, and especially if you're just starting out, it is highly recommended to use a hosted solution and let someone else deal with keeping your images safe and readily available.
