copied!<p>As Dhaivat said, you can just use your Flask app directly with Gunicorn.</p> <p>If you still want to use Flask-Script, you will need to create a custom <code>Command</code>. I don't have any experience with Gunicorn, but I found a similar <a href="https://bitbucket.org/youngking/flask-actions/src/381d6eea3e78/flaskext/actions/server_actions.py#cl-81" rel="nofollow noreferrer">solution</a> for Flask-Actions and ported it to Flask-Script, although be warned, it's untested.</p> <pre><code>from flask_script import Command, Option class GunicornServer(Command): description = 'Run the app within Gunicorn' def __init__(self, host='127.0.0.1', port=8000, workers=4): self.port = port self.host = host self.workers = workers def get_options(self): return ( Option('-H', '--host', dest='host', default=self.host), Option('-p', '--port', dest='port', type=int, default=self.port), Option('-w', '--workers', dest='workers', type=int, default=self.workers), ) def handle(self, app, host, port, workers): from gunicorn import version_info if version_info < (0, 9, 0): from gunicorn.arbiter import Arbiter from gunicorn.config import Config arbiter = Arbiter(Config({'bind': "%s:%d" % (host, int(port)),'workers': workers}), app) arbiter.run() else: from gunicorn.app.base import Application class FlaskApplication(Application): def init(self, parser, opts, args): return { 'bind': '{0}:{1}'.format(host, port), 'workers': workers } def load(self): return app FlaskApplication().run() </code></pre> <p>You can then either register it to replace Flask's <a href="http://flask.pocoo.org/docs/api/#flask.Flask.run" rel="nofollow noreferrer">local development server</a> at <code>python manage.py runserver</code> </p> <pre><code>manager.add_command("runserver", GunicornServer()) </code></pre> <p>or register as a new command such as <code>python manage.py gunicorn</code></p> <pre><code>manager.add_command("gunicorn", GunicornServer()) </code></pre> <p><strong>Edit June 2016</strong>: With the latest version of Flask-Script, change the method <code>handle</code> with <code>__call__</code>. <a href="https://github.com/smurfix/flask-script/blob/cb36eb94d6ae992458b6a66c6c2a715cddfdc4bd/flask_script/commands.py#L138" rel="nofollow noreferrer">old flask-script</a> vs <a href="https://github.com/smurfix/flask-script/blob/master/flask_script/commands.py#L210" rel="nofollow noreferrer">new flask-script</a></p>
