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.

Preparing node images

As we did in Chapter 3, Reach for the Cloud, we will now be preparing an AMI for the worker nodes in our cluster. However, we will improve this process by automating it with Packer. Packer is a tool that makes it simple to build machine images on AWS (and other platforms).

Installing Packer

Just like Terraform, Packer is distributed as a single binary that just needs to be copied to a location on your path. You can find detailed installation instructions on the Packer website at https://www.packer.io/intro/getting-started/install.html.

Once you have installed Packer, you can run packer version to check that you have correctly copied it into to your path.
