Containerizing Python Web APIs with Docker and FastAPI

Packaging and deploying web applications can often lead to the classic "it works on my machine" dilemma. Containerization solves this by ensuring your code runs exactly the same way in development, testing, and production. In this course, you will learn how to containerize Python web applications built with FastAPI using Docker. You will start with the fundamental concepts of containerization before moving on to writing efficient configuration files and managing images. What you'll learn: - Understand core containerization concepts, including the difference between images and containers - Write optimized Dockerfiles for Python applications using multi-stage builds - Manage modern Python dependencies inside containers using virtual environments - Configure environment variables and secure your FastAPI applications for production - Build, run, and debug Docker containers locally using command-line tools - Apply best practices for keeping container images small, secure, and lightweight You will begin by exploring the basic terminology of Docker and the architecture of FastAPI. Then, you will progress through structured text-based lessons that guide you in writing Dockerfiles, building images, and running containers. This course is designed for beginner Python developers and web creators looking to understand containerization. No prior experience with Docker is required.
