python - 如何为烧瓶 azure Web 应用程序设置启动命令

问题描述

我创建了一个简单的烧瓶 Web 应用程序，并设法使用 CI/CD 从 azure devops 将其发布到 azure Web 应用程序。除了启动我的应用程序外，管道都在工作。

如果我查看 webapp 中的日志文件，就会出现 -

日志文件 default_docker.log：

我的简化应用程序树视图看起来像这样 -

    test_app/
      venv/
      application/
        templates/
        __init__.py
        routes.py
        errors.py
        models.py
        forms.py
      app.py

我在 azure 门户“常规设置”中尝试了不同的启动命令，但没有解决方案

gunicorn --bind=0.0.0.0 --timeout 600  app:application

编辑：添加 app.py 和init .py

应用程序.py：

from application import app, db
from application.models import User, Post

@app.shell_context_processor
def make_shell_context():
    return {'db': db, 'User': User, 'Post': Post, 'Classrooms' : Classrooms, 'ClassSession' : ClassSession, 'Teacher' : Teacher}

初始化.py

from flask import Flask
from config import Config
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
from flask_login import LoginManager
from logging.handlers import RotatingFileHandler
import os
from flask_bootstrap import Bootstrap
import logging

app = Flask(__name__)
app.config.from_object(Config)
db = SQLAlchemy(app)
migrate = Migrate(app, db)
login = LoginManager(app)
login.login_view = 'login'
bootstrap = Bootstrap(app)

from application import routes, models, errors

if __name__ == '__main__':
    # * --- DEBUG MODE: --- *
    app.run(host='127.0.0.1', port=5000, debug=True)

谁能指出我可以解决这个愚蠢问题的方向。多谢！！

解决方案

gunicorn 命令实际上并不指向 WSGIapp对象。试试这个：

gunicorn --bind=0.0.0.0 --timeout 600  application:app
