Hi Vijay,
Thanks for reply.
Currently I am trying to create a stack using python API, The library I am
using is os_client_config, its a part of OpenstackClient.
In my last mail I explained how I am trying to create stack through
os_client_config.make_client('orchestration') object.
Can you help me with this, or is there any other library to create stack in
python.
Regards
