我已经在Flask sing eb（Elastic Beanstalk v3.1的终端客户端）上建立了一个站点。
当部署我的网站的新版本时，我会收到"更新环境操作已完成，但有错误。有关详细信息，请参阅疑难解答文档。"消息。
我有.ebextensions/aws.config文件
container_commands:
01_migrate:
command: "application.py db upgrade"
leader_only: true
我尝试使用ignoreErrors: true和不同的组合来执行命令，但没有成功。有什么想法可以解决这个问题或通过迁移升级逃脱惩罚吗？

编辑：在拼写错误修复之后事件消息：

这些是来自Elastic Beanstalk 的日志

请注意，您使用的解决方案堆栈是基于Docker的解决方案栈。因此，您的eb扩展将不会在docker上下文中运行，而是在主机中运行。
要执行所需操作，您需要更新python dockerfile(https://github.com/aws/aws-eb-python-dockerfiles/blob/master/3.4.2-aws-eb-onbuild/Dockerfile），以将升级步骤添加为该docker文件的一部分。完成后，您可以将docker文件与应用程序捆绑在一起，您的步骤将根据需要工作。
如果这能回答你的问题，请告诉我。
谢谢，Dhanvi
确保您处于迁移所需的python虚拟环境中。在我的例子中，我发现以下内容适用于Flask Migrate:
container_commands:
01_migrate:
command: "source /var/app/venv/staging-LQM1lest/bin/activate; flask db upgrade"
leader_only: true
将此文件添加到项目目录的根目录：
.ebextensions/migration.config
container_commands:
01_migrate:
command: "source /var/app/venv/staging-LQM1lest/bin/activate && python3 manage.py db upgrade"
leader_only: true
在EB环境配置/软件/环境属性中检查PYTHONPATH。我的是/var/app/venv/staging-LQM1lest/bin
manage.py是包含类似的内容的文件
import os
from flask_script import Manager
from flask_migrate import Migrate, MigrateCommand
from application import application, db
application.config.from_object(os.environ['APP_SETTINGS'])
migrate = Migrate(application, db)
manager = Manager(application)
manager.add_command('db', MigrateCommand)
if __name__ == '__main__':
manager.run()
