Overview of this book

Docker is an open source tool used for creating, deploying, and running applications using containers. With more than 100 self-contained tutorials, this book examines common pain points and best practices for developers building distributed applications with Docker. Each recipe in this book addresses a specific problem and offers a proven, best practice solution with insights into how it works, so that you can modify the code and configuration files to suit your needs. The Docker Cookbook begins by guiding you in setting up Docker in different environments and explains how to work with its containers and images. You’ll understand Docker orchestration, networking, security, and hosting platforms for effective collaboration and efficient deployment. The book also covers tips and tricks and new Docker features that support a range of other cloud offerings. By the end of this book, you’ll be able to package and deploy end-to-end distributed applications with Docker and be well-versed with best practice solutions for common development problems.

Introduction

In previous chapters, we have been fiddling a lot with Docker commands to work with Docker images, containers, volumes, and networks. One of the hallmarks of Docker is the amazing user experience it provides through its easy-to-remember and well-structured commands. With a single Docker command, we can spin a very useful microservice or utility container. However, behind the scenes, the Docker client translates our request into multiple API calls in order to fulfill it. These APIs are called Docker Engine APIs, and they are designed using the REST paradigm.

Note: REST (aka RESTful) stands for REpresentational State Transfer, which is a web standard for data communication over the HTTP protocol.

The Docker Engine API is documented using the OpenAPI (formerly known as Swagger) specification. As a result, we can access API help through any standard OpenAPI editor. In...
