Dockerizing FastAPI Applications
Learn to containerize your FastAPI service using Docker, creating efficient and portable deployment images.
Docker & FastAPI: Why Containerize?
Welcome! In this lesson, we'll learn how to package your FastAPI application using Docker. This makes your app incredibly consistent and easy to deploy anywhere.
- What is Docker? It's a platform that uses OS-level virtualization to deliver software in packages called containers.
- Why use it for FastAPI? It solves the "it works on my machine" problem by packaging your app and its dependencies together.
Docker's Core: Images & Containers
Before we dive into Dockerizing, let's understand two key concepts:
- Docker Image: Think of an image as a blueprint or a template. It's a static, immutable file that contains your application code, libraries, dependencies, and configuration.
- Docker Container: A container is a runnable instance of an image. It's an isolated environment where your application runs, completely separate from your host system.
You build an image, then run a container from it.
