Abhishek Kumar commented on RANGER-5514:
----------------------------------------
Bringing up ranger-admin container is documented here:
[https://hub.docker.com/r/apache/ranger]
hostname is an arg that is passed to docker run, have you tried using different
hostname when bringing up the ranger container?
> Ranger Admin expects hostname ranger-admin.rangernw

> {{localhost}} to access itself during setup.
