Deploy a Flask app

This guide replaces the old “How to deploy a Flask app on DockHive” page.

With Drone (recommended)

Push your code to GitHub, start a new app, pick the repository and click Deploy with Drone. Or run hivepod deploy in the project folder.

With the Flask preset

Pick Flask. DockHive installs requirements.txt and serves your app with gunicorn.

app.py

from flask import Flask

app = Flask(__name__)

@app.get("/")
def index():
    return "Hello from DockHive"

requirements.txt

flask
gunicorn

If your app object isn’t app in app.py, set the Start Command in Advanced Settings, for example:

gunicorn --bind 0.0.0.0:$PORT "myproject:create_app()"

Tips

• Don’t use Flask’s development server (app.run()) in production.
• To pick a Python version (3.9 to 3.13; the default is 3.12), add a .python-version file containing, for example, 3.11.
• Put your database URL and secret key in environment variables.
