Using FastAPI inside Docker containers

FastAPI is a Python web framework designed for building APIs, known for its use of modern Python-type hints, high performance, and ease of use. The framework benefits from Docker containers, which offer a solution to manage dependencies and environmental inconsistencies across different development setups, enhancing portability. By containerizing a FastAPI application, developers can create an isolated environment with all necessary dependencies, allowing for consistent deployment across various platforms. The process involves writing a Dockerfile to define the setup instructions, building a Docker image from this file, and running a container that encapsulates the application. This approach simplifies deployment and reduces configuration issues, making it easier to maintain consistent development and production environments. While Docker is a popular tool for containerization, the concept is not exclusive to FastAPI and can be applied to a wide range of projects and programming frameworks.
