Public bug reported:
On the server the docker.service is run.
Sometimes after reboots it hands down a default resolv.conf to docker
domains (8.8.8.8 and 8.8.4.4 if I'm correct) and NOT our local
resolv.conf (which is generated from /etc/network/interfaces).
It looks like a race condition between the docker service and the status
of the hosts /etc/resolv.conf (which is a link to
/run/resolvconf/resolv.conf) since other times thing work out OK.
network-online.target should only be met after
/run/resolvconf/resolv.conf is complete in my opinion.
docker-ce service definition is:
(/lib/systemd/system/docker.service)
Wants=network-online.target
