This is what my /etc/resolv.conf looks like:
# nameserver updated by /etc/NetworkManager/dispatcher.d/99-origin-dns.sh
# Generated by NetworkManager
search localdomain cluster.local
nameserver 10.0.0.245
That was with EC2. However, on Scaleway the line starting with search
was missing.
I believe the same installation approach was used on both.
Both have the same problem pushing to the docker registry.

Yeah, we
set OPENSHIFT_DEFAULT_REGISTRY=docker-registry.default.svc:5000 in
/etc/sysconfig/origin-master you can remove that and restart the
master and it will revert back to pushing via the service IP.
However the installer will deploy certificates, secure the registry,
and should be adding 'cluster.local' to /etc/resolv.conf so this
should all be seamless.

I saw the same thing on a new cluster. I resolved it manually by:
1) adding ‘search cluster.local’ to the node’s /etc/resolv.conf
2) adding docker-registry.default.svc and
docker-registry.default.svc.cluster.local to the docker daemon’s
insecure registries
then stopped the node service, restarted docker and started the
node service
Maybe #2 is unnecessary once you add the search directive to
resolv.conf, but didn’t try.
Scott, it seems the default is now to use the registry host name
instead of the numeric service IP. Is there a variable that
controls that?
