Manage Openstack with salt/ansible.

I am plaining to work on automating tasks which admin generally performs after deploying Openstack.For ex. create/delete/manage instances/volumes/network/heat-stack etc.

But, I am bit confused in between salt and ansible. Which one is mature for my usecase with good documentation? Can anyone suggest me the better option and examples if available?

Have you looked at the included modules both have?

https://docs.saltstack.com/en/latest/topics/cloud/openstack.html

Thanks for reply. I have deployed newton setup and currently I am playing with ansible modules. It seems to be ansible is handy here as there are lots of ansible modules than saltstack states. I might be wrong.

Pratik.
