Here is my configurations for my project: runtime: python37 entrypoint: gunicorn -w 4 -k main:app instance_class: F2 Your python version should be above 3.6 for FastAPI to work. To freeze the requirements file: pip freeze > requirements.txt Configuring app.yaml file To install Gunicorn: pip install gunicorn Freezing Requirements FileĪfter installing every required dependencies inside virtualenv, do not forget to freeze the requirements file to update before deploying as App Engine installs dependencies from requirements.txt file. You do not need to install Gunicorn while running locally. Uvicorn includes a gunicorn worker class that means you can get set up with very little configuration. Lastly, you should also install Gunicorn as it is probably the simplest way to run and manage Uvicorn in a production setting. I prefer using uvicorn as it installs cython-based dependencies which will prevent error related to uvloop and httptools while running in production. the http protocol will be handled by httptools if possible.the event loop uvloop will be installed and used if possible.In this context, “Cython-based” means the following: ![]() This will install uvicorn with “Cython-based” dependencies (where possible) and other “optional extras”. This will install uvicorn with minimal (pure Python) dependencies. The ASGI specification fills this gap, and means we’re now able to start building a common set of tooling usable across all asyncio frameworks. Until recently Python has lacked a minimal low-level server/application interface for asyncio frameworks. Uvicorn is a lightning-fast ASGI server implementation, using uvloop and httptools. We will be using uvicorn for this article. You will also need an ASGI server, for production such as Uvicorn or Hypercorn.

Deploying FastAPI application in Google App Engine in Standard EnvironmentįastAPI is a modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints. ![]()
