I want to change the host and port that my app runs on. I set
app.run, but the
flask run command still runs on the default
127.0.0.1:8000. How can I change the host and port that the
flask command uses?
if __name__ == '__main__': app.run(host='0.0.0.0', port=3000)
set FLASK_APP=onlinegame set FLASK_DEBUG=true python -m flask run
flask command is separate from the
flask.run method. It doesn’t see the app or its configuration. To change the host and port, pass them as options to the command.
flask run -h localhost -p 3000
--help for the full list of options.
SERVER_NAME config will not affect the command either, as the command can’t see the app’s config.
Never expose the dev server to the outside (such as binding to
0.0.0.0). Use a production WSGI server such as uWSGI or Gunicorn.
gunicorn -w 2 -b 0.0.0.0:3000 myapp:app
