flask - 使用 Elastic Beanstalk 设置 Flask 数据库迁移

Question

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

部署网站的新版本时，我收到“更新环境操作已完成，但出现错误。有关详细信息，请参阅故障排除文档”。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 和不同的命令组合，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

在运行 Python 3.4 的 64 位 Debian jessie v1.2.0 上使用 Python 3.4 部署的所有东西(预配置 - Docker)

编辑:拼写错误修复后事件消息:

[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

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 将不会在 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 ) 以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，并且您的步骤将根据需要进行。

如果这能解答您的问题，请告诉我。

谢谢，丹维
