nomad init example does not expose redis port

[ghost]

This may be related to a misreading of issue #185 or how the nomad init example file is supposed to work, however when scheduling the nomad init example redis instance port 6379 is not actually exposed on the docker host. Is this a placeholder example designed to just run the instance but not expose anything? Running example with count = 3 on a nomad 3 host cluster using master.

No hosts are actually forwarding through to 6379. If this is by design it would probably be helpful to update the example with an image setup to forward through as it's a bit confusing. I'm of the understanding from issue #185 that my container process must read an environment variable to bind properly.
