FastAPI is a web framework for building APIs with Python \u2265v3.6 that is based on standard Python-type hints. What makes FastAPI stand out is its focus on modern Python, high performance, and ease of use. But, you might be wondering how Docker containers come into the FastAPI conversation.<\/p>\"Fast\n

Imagine that you\u2019re building a REST API and you need to use PostgreSQL, Redis, Celery, RabbitMQ, and a bunch of other dependencies. The first problem you\u2019d run into is configuring all those dependencies on your machine. This setup process could be a hassle, however, there is another, more pressing problem.<\/p>\n

What if you\u2019re developing on Linux, but your colleague develops on Windows? You have to keep in mind that some dependencies that work well on Linux don\u2019t work well on Windows. And even if you somehow manage to get past the development phase, what if your development environment isn\u2019t consistent with your deployment environment? All these problems sum up to one thing, portability.<\/p>\n

To make your project more portable, you could develop in an isolated environment that has the project code and all the dependencies installed, which is exactly what Docker containers does.<\/p>\n

Docker isn\u2019t exclusive to FastAPI; we can use Docker to containerize most projects<\/a> regardless of what languages or frameworks are used. In this article, we\u2019ll learn how to containerize a FastAPI application with Docker.<\/p>\n
