Hi,
 I am a maintainer of the Zun project. From my perspective, I would like to
 have Zun supported by different deployment tools to minimize complexities
 for installing and managing the service. If TripleO community interests to
 add support for Zun, I am happy to provide necessary supports.
 
Because TripleO relies on modulus maintained by Puppet OpenStack project to
manipulate configurations,
you'd need to start with creating a new puppet module (puppet-zun) for it.
Also, we need distro packages to support zun in Puppet OpenStack and
TripleO.
Puppet-openstack relies on packages to install services , and TripleO
relies on RDO in CI.
I quickly checked RDO but it seems there are no zun packages there.
Also Ubuntu has zunclient packaged[2] but no packages available for server
side.

 @Lokendra, if you are open to consider alternative tools, I would suggest Kolla [1]. Its
support for Zun is quite solid and has CI to cover some basic senario. Another tool is
OpenStack Ansible [2]. I didn't try that one myself but it has Zun support based on
their document [3]. Lastly, the Zun community maintains an installation guide [4] which
you can refer if you want to install it manually.
