python - docker 中的 django 迁移权限被拒绝

Question

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

一切都很好，即使 django 容器已启动并运行到我想要 makemigrations 它会随着 django-celery-beat 停止

Migrations for 'django_celery_beat':
django_1        |   /usr/local/lib/python2.7/site-packages/django_celery_beat/migrations/0005_auto_20190512_1531.py
django_1        |     - Alter field event on solarschedule
django_1        | Traceback (most recent call last):

django_1        |   File "/usr/local/lib/python2.7/site-packages/django/core/management/commands/makemigrations.py", line 232, in write_migration_files

虽然用户模型是在迁移时写下来的，它应该是从 django 本身的 AbstractUser 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 但实际上我无法使用 sudo 权限运行此命令

那么我应该怎么做，我应该在 docker 中使用 virtualenv 运行图像，还是有任何调整来修复这个问题

Docker文件

今天遇到了同样的问题。我使用 docker 创建了一个项目，当我第一次尝试运行 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 makemigrations 解决了这个问题，指定了应用程序名称(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"
