Don't use the FQDN name
There's not much value in using the fqdn for docker instance resolving because all docker instances are usually on the same host machine. And they can resolve each other with the short hostnames.
OTOH, relying on the fqdn has caused problems in environments where a DNS Domain Name is provided, like for example the instances on Microsoft Azure environment, which provide their Azure domain names. This creates invalid OBS host name instances.
