Having the container running in OpenShift with a user ID from a higher range is a security good practice. The user ID won't match any user ID on the host. As an alternative to what Tim proposed you could modify your docker image and allow access to root group (0) to the necessary files. The user running the process inside the container on OpenShift is always part of this group and this group has no rights on the host.
