Dirk, Sadly I can't use localhost for all of those. 172.17.0.1 is an internal Docker IP, not the localhost address (127.0.0.1), they are there to handle two different scenarios and different ones will fail to resolve in different scenarios. Are you saying that the DNS lookup adds a timing issue to the search order? Isn't the list deterministically ordered?
