Description Paul Morie 2015-10-10 18:04:34 UTC

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'

Comment 1 Fedora Update System 2015-10-15 14:36:46 UTC

docker-io-1.8.2-2.gitcb216be.fc21 has been submitted as an update to Fedora 21. https://bodhi.fedoraproject.org/updates/FEDORA-2015-891d60ea2b

Comment 2 Fedora End Of Life 2015-11-04 15:54:50 UTC

This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '21'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 21 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 3 Fedora Update System 2015-11-08 10:19:36 UTC

docker-io-1.8.2-2.gitcb216be.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report.
