Deploying Python with Flask

This example runs Flask with a production WSGI server. Use the equivalent production command for Django, FastAPI, or another Python framework.

Review the Python deployment path, the focused Flask deployment page, or the Flask template before applying this configuration to an existing project.

Configuration

Create an adios.yaml file in the root of your project:

name: my-flask-api
build_cmd: pip install -r requirements.txt
start_cmd: gunicorn app:app --bind 0.0.0.0:$PORT

runtime:
  name: python@3.13
  port: 8000
  health_path: /healthz

env:
  FLASK_ENV: production

secrets:
  SECRET_KEY: secret://SECRET_KEY

Deploy

Before deploying, make sure to set your secrets using the CLI:

adios secret set SECRET_KEY

Then you can run the deployment command:

adios up
