我试图在docker容器上运行django应用程序。遵循https://docs.docker.com/compose/django/中提到的步骤，但是在运行命令docker-composerun webdjango-admin.pystart project comiceform之后。我面临错误PermissionError：[Errno 13]权限被拒绝：'/code/manage.py'我正在使用centos7.请帮忙

[root@localhost docker-django]# docker-compose run web django-admin.py startproject composeexample .
