This image aims to provide resolvable fully qualified domain names, between dynamically created docker containers on ubuntu.
By default /etc/hosts is readonly in docker containers. The usual
solution is to start a DNS server (probably as a docker container) and pass
a reference when starting docker instances: docker run -dns <IP_OF_DNS>
The guys at sequenceiq have done the fantastic job to solve this problem full credit to them.
