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.

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.
