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.

Tagging images

Whenever a Docker image is pushed to a registry, we need to identify the image with a tag. A tag can be any alphanumeric string: latest stable v1.7.3 and even c31b1656da70a0b0b683b060187b889c4fd1d958 are both perfectly valid examples of tags that you might use to identify an image that you push to ECR.

Depending on how your software is developed and versioned, what you put in this tag might be different. There are three main strategies that might be adopted depending on different types of applications and development processes that that we might need to generate images for.
