Expected behavior
Docker finds a valid DNS configuration
Actual behavior
After boot all works fine. After some time (i don’t know what causes it, it’s not the sleep state), docker will output “No upstream DNS configured” to the log. All other networking on OSX is working without the reconnect (including DNS resolution using dig).
Somehow it seems to be related to, if the first DNS entry on OSX is an IPv6 Address. At least if i change the DNS Config to an V4 Address it works again. But also if i reboot with an V6 Address still on the top.
