Welcome Vipul,

no big prefaces, I'd like the idea with blue/green deployment because we 
have to bridge downtime when DevStack is re-installing, requirement is 
once a week (day). And we have to pick a way return if DevStack 
installation failed. The reason for this is more DevStack specific 
because we want to use master branch with the newest changes.
I have gained some experience with LXD containter and want to push the 
topic a little bit forward. The draft of my idea is here: 
https://github.com/eumel8/translation_checksite/blob/container/translation_check_container.jpg
There are 2 container with DevStack installation + translation 
checksite. In front of the container is some magic, called Watchdog for 
installing the stuff and guarding the installation. Traffic will be 
route to the last available container version. Container installation is 
a little bit described here: 
http://docs.openstack.org/developer/devstack/guides/lxc.html But needs 
to adapt for LXD 2.0.
And we have to persuade the infra team to provide 16.04 VM :-)
Let me know what do you think.

kind regards

Frank
