marthon 1.7 mesos-dns default json #533

Closed f1-outsourcing closed 5 years ago

f1-outsourcing commented 5 years ago

Sorry for asking maybe the obvious I am having a test setup and just upgraded to mesos 1.7 and marathon 1.7. Marathon is now running as uid marathon. And I have probably problems launching the mesos-dns because of the low port 53 in the mesos-dns.json. (If I change it to 2053 it deploys)

How should I resolve this issue? I guess I need to have the 53 port.

@f1-outsourcing did you found a solution?

yes run as root, all ports below 1024 require it, otherwise you need to do something with port forwarding etc etc.
