Description Prasanth 2016-10-25 19:02:48 UTC
+++ This bug was initially created as a clone of Bug #1388621 +++

Description of problem:

I'm seeing the following AVC's while trying to create a router:

Version-Release number of selected component (if applicable):
docker-selinux-1.10.3-46.el7.14.x86_64
docker-1.10.3-46.el7.14.x86_64
selinux-policy-3.13.1-102.el7.noarch
atomic-openshift-3.4.0.15-1.git.0.9c963ec.el7.x86_64

# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.3 (Maipo)

# uname -r
3.10.0-514.el7.x86_64

How reproducible: 100%


Steps to Reproduce:
1. # oadm router storage-project-router --replicas=1
2.
3.

Actual results: Router creation is NOT successful and AVC's are seen


Expected results: Router creation should be successful and NO AVC's should be seen

--- Additional comment from Red Hat Bugzilla Rules Engine on 2016-10-25 14:59:01 EDT ---

This bug is automatically being proposed for the current release of Red Hat Gluster Storage 3 under active development, by setting the release flag 'rhgs‑3.2.0' to '?'. 

If this bug should be proposed for a different release, please manually change the proposed release flag.

Comment 1 Daniel Walsh 2016-11-04 12:38:49 UTC
We seem to have a bad version of docker and docker-selinux in the release?

Comment 2 Prasanth 2016-11-08 06:41:00 UTC
I've re-tested this using the latest RHEL-7.3 GA bits and looks like the router creation works well with SELinux in Enforcing mode.
