Comment 3 seb 2017-05-30 14:43:52 UTC

Harish, what does QE think about this?
Thanks.

Comment 4 Harish NV Rao 2017-05-30 14:50:31 UTC

Sebastien, is this a must fix for 2.3? We just have very few days to QE completion....

Comment 5 seb 2017-05-30 16:38:11 UTC

This is not a must-fix. I'm just not sure how this is working... but seems to be working without this patch. I'm still investigating though.

Comment 6 Ken Dreyer (Red Hat) 2017-06-01 16:19:50 UTC

The hostname package is probably part of an RPM that ceph pulls in. 

rpm -qf /usr/bin/hostname
hostname-3.13-3.el7.x86_64

Try "yum remove hostname" in a running container to find out exactly what the dependency chain is.

Comment 7 seb 2017-06-02 09:59:40 UTC

This is strange, see:

[root@leseb-tarox ~]# docker run -ti --entrypoint=/bin/bash brew-pulp-docker01.web.prod.ext.phx2.redhat.com:8888/rhceph:ceph-2-rhel-7-docker-candidate-20170417171705
[root@2b84e3c1ac9a /]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.3 (Maipo)
[root@2b84e3c1ac9a /]# ceph -v
ceph version 10.2.7-6.el7cp (750b38d01c7e11bf8c9cc48664dd79085f76c94c)
[root@2b84e3c1ac9a /]# hostname
bash: hostname: command not found
[root@2b84e3c1ac9a /]# rpm -qf /usr/bin/hostname
error: file /usr/bin/hostname: No such file or directory

Comment 8 Ken Dreyer (Red Hat) 2017-06-02 12:39:43 UTC

Oh, got it, then PR 655 looks like the way to avoid installing the hostname RPM.

Comment 9 seb 2017-06-12 10:02:01 UTC

merge upstream, backport in progress

Comment 13 Vasishta 2017-09-06 14:48:41 UTC

Hi all,

Moving the BZ to VERIFIED state.

$  sudo docker exec d6153ad10e34 hostname
magna025
$  sudo docker exec d6153ad10e34 rpm -qf /usr/bin/hostname
hostname-3.13-3.el7.x86_64

Regards,
Vasishta
