如何通过 eb cli (django postgres) 迁移 AWS RDS 数据库？
How can I migrate AWS RDS database through eb cli (django postgres)?
我有一个使用 elastic beanstalk CLI 部署的 django 项目。
我添加了一个postgres数据库（AWS RDS），连接是运行nning.
我的数据库还是空的。我如何 运行 迁移命令或 eb shell 中的“python manage.py createsuperuser”？
当我打开 eb ssh <env> 并尝试 ls 时，没有任何显示。使用 cd .. 后退一个目录并再次 ls 显示 ec2-user、healthd 和 网络应用。我没有进入这些文件夹的权限。在 eb ssh 中使用 运行 python 命令是不可能的吗？
我也试过容器命令，.ebextensions/db-migrate.config:
container_commands:
01_makemigrations:
command: "python manage.py makemigrations"
leader_only: true
02_migrate:
command: "python manage.py migrate --first main initial && python manage.py migrate"
leader_only: true
option_settings:
aws:elasticbeanstalk:application:environment:
DJANGO_SETTINGS_MODULE: <app>.settings
使用 eb deploy 再次提交和部署后，出现此错误：
eb deploy
Creating application version archive "app-xxxx".

为什么命令失败？任何建议表示赞赏。顺便说一句，我用本地 sql db.
部署没有问题
更新：
eb-engine.log 让我参考 cfn-init.log。这是输出：
2021-02-22 16:49:43,624 [ERROR] Command 01_makemigrations (python
manage.py makemigrations) failed

在路径中我看到 python 2.7 (?) 但实际上 Python 3.7 在 64 位亚马逊上 运行ning Linux 2. 我也尝试执行命令与“python3”。
问题是此时没有加载 django。
解决方案：
container_commands:
01_migrate:
command: |
source $PYTHONPATH/activate
pipenv run python ./manage.py migrate
将您引向 eb-engine.log 和 cfn-init.log 的日志，但我在 cfn-init-cmd.log 中找到了最后的提示：
2021-02-23 11:08:34,019 P5022 [INFO] ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
我也尝试过“createsuperuser”。完全没有错误，但也没有创建新用户。没有活动的命令行输入 username/password。如果我找到了 createsuperuser 的解决方案，我会尝试更新我的答案。
我可以提出一个替代方法：
与其从 eb shell 中使用 运行ning Django 管理命令，不如将本地 Django 项目的 DATABASE settings 调整到远程数据库，并从本地终端执行管理命令。
这对于 运行 临时命令很有用，例如 createsuperuser，但对于日常维护命令，例如 migrate，您需要坚持使用container_commands 作为部署过程一部分的方法。
最后，如果您决定 运行 createsuperuser，特别是在 eb shell 中，那么您可以使用 container_commands 以非交互方式执行此操作, 配置了一些额外的设置。来自 Django Docs:
When run interactively, this command will prompt for a password for the new superuser account. When run non-interactively, you can provide a password by setting the DJANGO_SUPERUSER_PASSWORD environment variable. Otherwise, no password will be set, and the superuser account will not be able to log in until a password has been manually set for it.
In non-interactive mode, the USERNAME_FIELD and required fields (listed in REQUIRED_FIELDS) fall back to DJANGO_SUPERUSER_<uppercase_field_name> environment variables, unless they are overridden by a command line argument. For example, to provide an email field, you can use DJANGO_SUPERUSER_EMAIL environment variable.
