Expose Mesos DNS API on master node under /mesos_dns

[jonas]

Motivation

Fix dcos node ssh --master and dcos node ssh --slave=X to work.

Input

dcos node ssh command does not work since it requires that the Mesos DNS API is exposed on one of the externally accessible nodes in the cluster under /mesos_dns.

$ dcos node ssh --master
Error while fetching [http://master.mesos:5050/mesos_dns/v1/hosts/leader.mesos.]: HTTP 404: Not Found

• Mesosphere's nginx router scripts: https://github.com/mesosphere/adminrouter-public

Output

• Mesos DNS API exposed on one of the externally accessible node(s) under /mesos_dns.
