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.

Cluster architecture

The cluster we are going to set up in this chapter will be formed of two EC2 instances—one that will run all the components for the Kubernetes control plane and another worker node that you can use to run your applications.

Because we start from scratch, this chapter will also lay out one method for isolating your Kubernetes cluster in a private network while allowing you easy access to the machines from your own workstation.

We will achieve this by using an additional instance as a bastion host that will allow incoming SSH connections from the outside world, as shown in the following diagram. If your AWS account already has some infrastructure in place that can achieve this, then feel free to skip this section:
