i try use Application Factories in this docker.
main.py is :

from flask import Flask
from flask import current_app, Blueprint, render_template
admin = Blueprint('admin', name, url_prefix='/')
@admin.route('/')
def hello():
return "Hello World test "
def create_app():
app = Flask(name)
app.register_blueprint(admin)
return app
if name == "main":
app = create_app()
app.run(host='0.0.0.0', debug=True, port=80)

work great on pycharm.
not work in this docker.
is supported?

file：
.:
app
Dockerfile

./app:
main.py

Dockerfile：
FROM tiangolo/uwsgi-nginx-flask:python3.6-alpine3.7
COPY ./app /app

Hmm, I'm not sure if I understand your issue.

Could you please create a repository that replicates your problem? That way I can check it and try to see the issue.

Your app is only being created when you call the file directly.

That's because of the:

if __name__ == "__main__":

You need to create your app before that section. That way, uWSGI can import and call it.

That's why the error log shows:

zzcld_1  | unable to load app 0 (mountpoint='') (callable not found or import error)
zzcld_1  | *** no app loaded. GAME OVER ***
zzcld_1  | 2018-11-09 17:23:49,112 INFO exited: uwsgi (exit status 22; not expected)
zzcld_1  | 2018-11-09 17:23:50,114 INFO gave up: uwsgi entered FATAL state, too many start retries too quickly

I just sent you the fix as a PR: https://github.com/jackadam1981/testflask/pull/1
