Rust Web Programming - Second Edition

By: Maxwell Flitton

Overview of this book

Are safety and high performance a big concern for you while developing web applications? With this practical Rust book, you’ll discover how you can implement Rust on the web to achieve the desired performance and security as you learn techniques and tooling to build fully operational web apps. In this second edition, you’ll get hands-on with implementing emerging Rust web frameworks, including Actix, Rocket, and Hyper. It also features HTTPS configuration on AWS when deploying a web application and introduces you to Terraform for automating the building of web infrastructure on AWS. What’s more, this edition also covers advanced async topics. Built on the Tokio async runtime, this explores TCP and framing, implementing async systems with the actor framework, and queuing tasks on Redis to be consumed by a number of worker nodes. Finally, you’ll go over best practices for packaging Rust servers in distroless Rust Docker images with database drivers, so your servers are a total size of 50Mb each. By the end of this book, you’ll have confidence in your skills to build robust, functional, and scalable web applications from scratch.

Managing our software with Docker

So far, we have been using Docker to manage our PostgreSQL and Redis databases. When it comes to running our frontend and Rust server, we have merely been running it directly on our local computer. However, when it comes to running our applications on remote servers, it is simpler and easier to distribute. Before we get on to deploying our Docker images on servers, we need to build and run them locally, which starts with writing our Docker image file.

Writing Docker image files

Before we proceed, it must be noted that the approach carried out here is the simplest, least optimized way to build a Rust server Docker image, because we are juggling a lot of new concepts. We cover an optimized way of building Rust server Docker images in Chapter 13, Best Practices for a Clean Web App Repository. When it comes to building a Docker image, we need a Dockerfile. This is where we define the steps needed to build our image. In our web_app/Dockerfile file...
