Description Lokesh Mandvekar 2015-10-15 10:47:18 EDT

+++ This bug was initially created as a clone of Bug #1270529 +++

Description of problem:

Docker can't start containers that use supplemental groups but do not have an /etc/groups file in their filesystem.  

The bug has been fixed in runc:

https://github.com/opencontainers/runc/pull/313

And there is a patch for the Red Hat docker:

https://github.com/rhatdan/docker/pull/127

Version-Release number of selected component (if applicable):

1.8

How reproducible:

Create a busybox container and set supplemental groups on it:

docker run --group-add=[123] -it busybox id -G

Actual results:

Container fails

Expected results:

Container starts and prints '123'
