[Bug 1121100] New: allow docker run --net=none --hostname=....

[Red Hat Bugzilla]

https://bugzilla.redhat.com/show_bug.cgi?id=1121100

            Bug ID: 1121100
           Summary: allow docker run --net=none --hostname=....
           Product: Fedora EPEL
           Version: el6
         Component: docker-io
          Severity: medium
          Assignee: lsm5(a)fedoraproject.org
          Reporter: gilles.gouaillardet(a)gmail.com
        QA Contact: extras-qa(a)fedoraproject.org
                CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org,
                    hushan.jia(a)gmail.com, jperrin(a)centos.org,
                    lsm5(a)fedoraproject.org, mattdm(a)redhat.com,
                    mgoldman(a)redhat.com, s(a)shk.io, vbatts(a)redhat.com



Currently, docker run will fail if both --net=none and --hostname=... options
are used.

This has been fixed in the docker git repository :
https://github.com/ggouaillardet/docker/commit/f411f8bfc5d04aed6499dfc90e...

could you please backport this fix to docker-io for epel-6 ?

Thanks and regards,

Gilles

Hi Gilles,

This will be available once version v1.1.1 (or later) will be packaged for
EPEL6. Or is there a plan to backport it? Lokesh?

Bug 1118603 does track some new dependencies which are needed for 1.1.1 which
will need to get completed.

Vincent: ping

Hi Marek and all,

the latest CentOS 7 (and hence RHEL 7 i guess) also does not support both
--net=none and --hostname=...

as a side note, and thought i was able to rebuild docker on CentOS 7, i
initially failed rebuilding docker-io on CentOS 6 :

# rpmbuild -ba SPECS/docker-io.spec 
error: Failed build dependencies:
    golang(github.com/gorilla/mux) >= 0-0.13 is needed by
docker-io-1.0.0-7.el6.x86_64
    golang(github.com/kr/pty) >= 0-0.19 is needed by
docker-io-1.0.0-7.el6.x86_64
    golang(github.com/coreos/go-systemd) >= 2-1 is needed by
docker-io-1.0.0-7.el6.x86_64
    golang(github.com/syndtr/gocapability/capability) >= 0-0.7 is needed by
docker-io-1.0.0-7.el6.x86_64

if i rpmbuild --nodeps ..., docker fails to start a container
(error message is "Invalid argument")

if i update from the required packages from epel-testing repo, then it works
fine.

i initially tried to workaround this issue by using --lxc-conf="lxc.utsname =
..." instead of --hostnane=... but the first option had no effect (e.g. the
host name was automatically generated by docker)

--- Comment #4 from Gilles Gouaillardet <gilles.gouaillardet(a)gmail.com&gt; ---
one more note ...
after applying the patch, the /etc/hosts of the container is invalid :
the ip address of the host is a dynamic one (e.g. the one that would have been
used without --net=none --lxc-conf= ...) instead of the one passed on the
command line with --lxc-conf="lxc.network.ipv4 = a.b.c.d"

as a work around, i configured a dns and the container /etc/nsswitch.conf to
use dns only

Gilles, could you check if docker 1.1.2 takes care of this bug?

docker 1.1.2 does take care of the initially reported bug

that being said, the /etc/hosts is incorrectly generated.
if run several times in a row
docker run ... grep myhostname /etc/hosts

then i always get a different result/ip which is different from the one i
requested via --lxc-conf="lxc.network.ipv4=..."
