让非根用户在Docker中写入linux主机

I have an OpenSuse 42.3 docker container image that I created which has a single user, which we will call 'streamuser'. I would like this to be the user that is active whenever anyone creates a container from my image. I have mounted the host's home directory to the home directory of streamuser. The trouble that I'm having is that if I run the Docker container on a Linux host, streamusercan not write anything to the host directories. This is because streamuser does not share the same UID and GID as the host. Is there a clean way to resolve this issue that avoids me setting the default user account in the image to the root account? If I login as root in the container, then I can write to the linux host, but this is undesirable.I have an OpenSuse 42.3 docker container image
