Docker for Serverless Applications. Containerize and orchestrate functions using OpenFaas, OpenWhisk, and Fn

Serverless applications have gained a lot of popularity among developers and are currently the buzzwords in the tech market. Docker and serverless are two terms that go hand-in-hand.This book will start by explaining serverless and Function-as-a-Service (FaaS) concepts, and why they are important.

• Then, it will introduce the concepts of containerization and how Docker fits into the Serverless ideology.

• Then, this book will discuss how to set up and operate a production-grade Docker cluster.

It will explore the architectures and components of three major Docker-based FaaS platforms, how to deploy and how to use their CLI. We will cover all concepts of FaaS frameworks with practical use cases, followed by deploying and orchestrating these serverless systems using Docker.

Finally, we will also explore advanced topics and prototypes for FaaS architectures in the last chapter.By the end of this book, you will be in a position to build and deploy your own FaaS platform using Docker.
