我已经建立了一个基于 Flask sing 的站点eb（Elastic Beanstalk v3.1 的终端客户端）。

部署我的站点的新版本时，我收到“更新环境操作已完成，但出现错误。有关更多信息，请参阅故障排除文档。” 信息。

我有.ebextensions/aws.config档案

container_commands:
  01_migrate:
    command: "application.py db upgrade"
    leader_only: true

我尝试ignoreErrors: true对命令使用不同的组合，但没有成功。有什么想法可以解决这个问题或摆脱迁移升级吗？

版本：

alembic==0.7.4
awsebcli==3.1
cement==2.4.0
Flask==0.10.1
Flask-Migrate==1.3.0
Flask-Script==2.0.5
Flask-SQLAlchemy==2.0
itsdangerous==0.24
Jinja2==2.7.3
jmespath==0.6.1
Mako==1.0.1
MarkupSafe==0.23
psycopg2==2.6
python-dateutil==2.4.0
PyYAML==3.11
six==1.9.0
SQLAlchemy==0.9.8
Werkzeug==0.10.1

Eerything 在运行 Python 3.4 的 64 位 Debian jessie v1.2.0 上使用 Python 3.4 部署（预配置 - Docker）

编辑：拼写错误修复事件消息后：

[Instance: i-a1627aab Module: AWSEBAutoScalingGroup ConfigSet: null] Command failed on instance. Return code: 1 Output: [CMD-AppDeploy/AppDeployStage0/EbExtensionPostBuild] command failed with error code 1: Error occurred during build: Command 01_migrate failed.

这些是来自 Elastic Beanstalk 的日志

@dnuske

请注意，您使用的解决方案堆栈是基于 Docker 的解决方案堆栈。因此，您的 eb-extensions 不会在 docker 上下文中运行，而是在主机中运行。

要执行您需要的操作，您需要更新 python dockerfile ( https://github.com/aws/aws-eb-python-dockerfiles/blob/master/3.4.2-aws-eb-onbuild/Dockerfile )将升级步骤添加为该 docker 文件的一部分。完成此操作后，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进行。

请让我知道这是否回答了您的问题。

谢谢，丹维

确保您处于迁移所需的 python 虚拟环境中。在我的实例中，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

检查PYTHONPATH您的 EB 环境配置/软件/环境属性。我的是/var/app/venv/staging-LQM1lest/bin

manage.py是包含类似内容的文件

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()
