--- Comment #4 from Bill C. Riemers <briemers(a)redhat.com> ---
Darn. "yum downgrade docker-io" won't work because the previous version is
no
longer in the official repository. For comparison I tried on a server I with
a different version of docker-io:
-bash-4.1$ rpm -qa |grep docker-io
docker-io-1.0.0-3.el6.x86_64
-bash-4.1$ sudo docker run fedora cat /etc/resolv.conf
[sudo] password for briemers:
; search domain for
devlab.redhat.com on
sfa-docker.devlab.redhat.com
search
devlab.redhat.com redhat.com
nameserver 10.7.142.20
nameserver 10.7.142.21
options timeout:1
-bash-4.1$ cat /etc/resolv.conf
; search domain for
devlab.redhat.com on
sfa-docker.devlab.redhat.com
search
devlab.redhat.com redhat.com
nameserver 10.7.142.20
nameserver 10.7.142.21
options timeout:1
So it looks like the 1.0.0-3 version simply copied /etc/resolv.conf directly.
I don't really know what the 1.0.0-8 version did, but whatever it did it also
worked on my laptop. Even the 1.0.0-3 version behavior is preferable to the
1.0.0-9 version, in that at least that only requires special docker-io
configuration when one is running their own dns server. In most cases, the
1.0.0-3 version should simply work out of the box, as expected.
