在Google App Engine上运行Alembic迁移

问题描述

我有一个使用SQLAlchemy（Flask-SQLAlchemy）和Alembic（Flask-Migrate）的Flask应用程序。该应用在Google App Engine上运行。我想使用Google Cloud SQL。

在我的机器上运行 python manage.py db upgrade 来运行我的本地数据库迁移。由于GAE不允许运行任何shell命令，我如何在其上运行迁移？

解决方案

将本地计算机的IP列入白名单：

创建用户：

为实例指定一个外部IP地址：

使用以下SQLAlchemy连接URI： SQLALCHEMY_DATABASE_URI ='mysql：// user：pw @ ip：3306 / DBNAME'

请记住随后发布IP，因为每个小时都会收取费用。

I have a Flask app that uses SQLAlchemy (Flask-SQLAlchemy) and Alembic (Flask-Migrate). The app runs on Google App Engine. I want to use Google Cloud SQL.

On my machine, I run python manage.py db upgrade to run my migrations against my local database. Since GAE does not allow arbitrary shell commands to be run, how do I run the migrations on it?

解决方案

• Whitelist your local machine's IP: https://console.cloud.google.com/sql/instances/INSTANCENAME/access-control/authorization?project=PROJECTNAME
• Create an user: https://console.cloud.google.com/sql/instances/INSTANCENAME/access-control/users?project=PROJECTNAME
• Assign an external IP address to the instance: https://console.cloud.google.com/sql/instances/INSTANCENAME/access-control/ip?project=PROJECTNAME
• Use the following SQLAlchemy connection URI: SQLALCHEMY_DATABASE_URI = 'mysql://user:pw@ip:3306/DBNAME'
• Remember to release the IP later as you are charged for every hour it's not used
