Google App Engine 不为我在 app.yaml 中定义的入口点提供服务

Question

Google App Engine will not serve my defined entrypoint on python37 runtime. GAE still try to serve a main.py file.

Project structure

/backend/__init__.py
/backend/views.py
/backend/models.py
app.yaml

app.yaml

service: backend
runtime: python37
entrypoint: gunicorn -b :$PORT backend:app
handlers:
  - url: /.*
    script: auto
    secure: always
    redirect_http_response_code: 301

/backend/ init .py

from flask import Flask
...
app = Flask(__name__)
...
import backend.models
import backend.views
if __name__ == '__main__':
    app.run()

GAE error message

File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked: ModuleNotFoundError: No module named 'main'

Answer 1

If you specify a custom entrypoint in your app.yaml file with gunicorn you have to install gunicorn in your requirements.txt . That did the trick for me and solved this issue!

Answer 2

You need to configure gunicorn to look at the directory where your init.py is located. There are two ways to do this on your entrypoint:

entrypoint: gunicorn -b :$PORT --chdir backend init:app 

or

entrypoint: gunicorn -b :$PORT backend.init:app
