Open Stack

Hi Dmitriy, Thanks for the response.  Sorry, I forgot to mention that i
used kolla ansible for deployment. As per kolla docs, glance-api container
runs only in one controller. So i am looking from kolla perspective if it
can automatically switch it over other available controllers.

Regards
Pradeep
