Provide additional environment details (physical.):

List the steps to reproduce the issue:

1. create a configuration follow https://docs.docker.com/compose/django/ , (before "Build the project")
2. add privileged in docker-compose.yml or execute sudo setenforce 0 to make container cloud write file into volumes.
3. run docker-compose run web django-admin.py startproject composeexample .
4. the files generated by Django were created by 'root' user

My question is: Is there any way to make the container generated files use host user and group ?

I found a solution, just add --user 1000:1000
or add in docker-compose.yml

user: "1000:1000"
