Overview of this book

The small scope and self-contained nature of microservices make them faster, cleaner, and more scalable than code-heavy monolithic applications. However, building microservices architecture that is efficient as well as lightweight into your applications can be challenging due to the complexity of all the interacting pieces. Python Microservices Development, Second Edition will teach you how to overcome these issues and craft applications that are built as small standard units using proven best practices and avoiding common pitfalls. Through hands-on examples, this book will help you to build efficient microservices using Quart, SQLAlchemy, and other modern Python tools In this updated edition, you will learn how to secure connections between services and how to script Nginx using Lua to build web application firewall features such as rate limiting. Python Microservices Development, Second Edition describes how to use containers and AWS to deploy your services. By the end of the book, you’ll have created a complete Python application based on microservices.

Introduction to Docker

Let's experiment with Docker containers. Running a container that you can enter commands in is as simple as the following:

docker run --interactive --tty ubuntu:20.04 bash

With this command, we are telling Docker to run the Ubuntu image, which will be fetched from Docker Hub, a central registry of public images. We are providing a tag of 20.04 after the image name so that we download the container image that represents the Ubuntu 20.04 operating system. This won't contain everything that a regular Ubuntu installation has, but anything that's missing is installable.

We also tell Docker to run interactively—the -i argument—and to assign a tty with the -t argument, so that we can type commands inside the container. By default, Docker assumes that you want to start a container that runs in the background, serving requests. By using these two options and asking that the command bash is run inside the container, we can...
