how to install and configure private Openstack for launch HDP cluster through Cloudbreak?

[#1]

I installed openstack(queen version) and cloudbreak on 2 different VM. As per the hortonworks document created credentials as well, but while launching the cluster getting this error: image copy failed.

I followed this URL as it is to installed Openstack : https://www.tecmint.com/openstack-installation-guide-rhel-centos/

After reviewing above URL please do let me know what all the steps I am missing or what is the right way to create Private cloud to launch HDP cluster?

Seems the issue is the image is not available in your openstack installation. I don't know where are the official images are located, but you can burn your own any time. For more information please check https://github.com/hortonworks/cloudbreak-images
