Comment 3 lkuchlan 2016-03-22 09:21:50 UTC

Emilien, can you please provide how to deploy multiple back-ends in single deployment using OSPD?

Comment 4 Mike Burns 2016-03-22 12:07:55 UTC

The description of how is in bug 1269990

Comment 6 lkuchlan 2016-03-23 13:41:10 UTC

Tested using:
openstack-puppet-modules-7.0.15-1.el7ost.noarch

Verification flow:
