Running FastAPI applications in Docker containers

Docker is a useful tool that lets developers wrap applications with their dependencies into a container. This method makes sure that the application operates reliably in different environments, avoiding the common works on my machine issue. In this recipe, we will see how to make a Dockerfile and run a FastAPI application inside a Docker container. By the end of this guide, you will know how to put your FastAPI application into a container, making it more flexible and simpler to deploy.

Getting ready

You will benefit from some knowledge of container technology, especially Docker, to follow the recipe better. But first, check that Docker Engine is set up properly on your machine. You can see how to do it at this link: https://docs.docker.com/engine/install/.

If you use Windows, it is better to install Docker Desktop, which is a Docker virtual machine distribution with a built-in graphical interface.
