Amrith, those doc doesn't reflect any post-deployment steps, even more, doc
still suggesting to use trove-cli that was deprecated long time ago. I do
agree that trove-integration project can't be used as production deployment
system, but first try-outs - more than enough.

Syed, i'd suggest to use heat-jeos
<http://docs.openstack.org/developer/heat/getting_started/jeos_building.html>
tools to build custom images for Trove. Since it doesn't forces you to
relay on any pre-baked images built for other production deployments.
 Or there's another way to accomplish Trove instances provisioning - you
are able to use cloud-init mechanism (for more information see link
<https://github.com/openstack/trove/blob/master/trove/common/cfg.py#L237-L239>
- option for Trove-taskamanger service, each cloud-init script should be
placed under {{cloud-init-script-location}}/{{datastore}}
(/etc/trove/cloud-init/mysql, etc.)
