Clojurians Log v2

Hi. I was trying pedestal with docker, and found out that even the hello world initial template wont work unless you set,

In service.clj:              ::http/host "0.0.0.0"

Would be nice to update the template’s README or the DOCKERFILE to mention this small detail.

I took a crack at updating the README https://github.com/pedestal/pedestal/pull/613
