docker 中的 Django 迁移权限被拒绝

Question

我正在使用 docker compose with django - postgres - rabbitmq

一切顺利，即使 django 容器已经启动运行我想要的点 makemigrations 它会随着 django-celery-beat

停止

Migrations for 'django_celery_beat':

虽然用户模型是在迁移时写下来的，它应该是从 AbstractUser 在 django 本身继承的，但那里没有引发权限错误

django_1        | Migrations for 'users':
django_1        |   users/migrations/0001_initial.py
django_1        |     - Create model UserAccount
django_1        |     - Create model Branch
django_1        |     - Create model Organization
django_1        |     - Add field organization to branch
django_1        |     - Add field bills_groups to useraccount
django_1        |     - Add field branch to useraccount
django_1        |     - Add field groups to useraccount
django_1        |     - Add field user_permissions to useraccount

所以我尝试将 sudo 用户添加到 python-2.7 alpine，但实际上我未能运行使用 sudo 权限执行此命令

那么我该怎么办，我应该运行在 docker 中使用 virtualenv 图像，还是有任何调整来修复这个

Answer 1

今天遇到同样的问题。我使用 docker 创建了一个项目，当第一次尝试运行 makemigrations 时，出现了这个错误：

PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.7/site-packages/django/contrib/admin/migrations/0004_auto_20190515_1649.py'

我通过运行宁 makemigrations 解决了它指定应用程序名称（核心是应用程序名称），如下所示：

docker-compose run web_app sh -c "python manage.py makemigrations core"

Answer 2

我刚刚在 docker 中使用了 virtualenv 并将对环境 site-packages dir

的所有权授予我的用户

RUN pip install virtualenv && virtualenv -p python /app/venv
RUN /app/venv/bin/pip install -r req.txt
RUN /app/venv/bin/python /app/code/manage.py makemigrations

和完成

Answer 3

我在 Linux，在我的情况下，这只是转到存储迁移的文件夹并为文件夹本身提供足够权限的情况。

例如：

chmod . 666

docker 中的 Django 迁移权限被拒绝

Permission denied with django migrations in docker
