我遇到的错误是，我想在 Docker 机器中执行“更改目录”命令，但每次在 Dockerfile 中执行 RUN 指令时，它都会删除实际容器（中间容器）。

Dockerfile

当我从上面执行 Dockerfile 时会发生这种情况

我怎样才能阻止 Docker 这样做呢？

I\xc2\xb4m 尝试使用 Django 登录没有密码的用户，到目前为止我已经创建了这个：

无密码.py

class PasswordlessAuthBackend(ModelBackend):\n   \n    def authenticate(self, username=None):\n        try:\n            return User.objects.get(username=username)\n        except User.DoesNotExist:\n            return None\n\n    def get_user(self, user_id):\n        try:\n            return User.objects.get(pk=user_id)\n        except User.DoesNotExist:\n            return None\n

视图.py

from .Nopassword import PasswordlessAuthBackend\nuser = User()\np = PasswordlessAuthBackend()\nuser.username = p.get_user(user_id=None)\nuser = p.authenticate(username=user.username)\n\n\ndef home(request):\n    login(request, user)\n

问题是，当我运行 web 应用程序时，我\xc2\xb4m 收到此错误：
