Open Stack

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.


@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.

[3] https://docs.openstack.org/openstack-ansible-os_zun/latest/
[4] https://docs.openstack.org/zun/latest/install/







Best regards,
Hongbin
