[rdo-list] tripelo installation

Few questions about tripleo: I got a requirement from my boss to create a production environment of openstack, usually I'm using packstack since he is very easy and robust installer, The issue is that the repos of the release kept for 3 versions only which breaks packstack My questions is: * Can I freeze versions with tripleo or there is any downloads from the net in the deployments? * How difficult is to upgrade versions * Can someone redirect me to a guide that explain how to build the topology and how to add compute / publish configuration change to the environment? Thanks,
