OpenStack is picking up a lot of steam these days, but getting it installed can be a hassle. Lots of puppet-based installers have popped up to automate this arduous task. Using Foreman, however, administrators can not only configure and install OpenStack using puppet, but provision & add new compute nodes at their fancy.
The Foreman is a Ruby on Rails application that does configuration management with puppet and provisioning. We’ll use both of these features to make using & administering OpenStack easier. Our installer leverages PackStack, which includes great puppet modules for setting up OpenStack. Combining these to setup and manage OpenStack Grizzly is a breeze!
- At least three machines running RHEL 6.4 with an active subscription to RHEL OpenStack Platform or Red Hat Cloud Infrastructure.. We recommend your OpenStack Compute & Controller nodes run on bare metal.
- Each machine needs to have a resolvable FQDN
- Each machine needs to be subscribed to a proper RHEL subscription
- The Foreman server should have its firewall configured to allow inbound network traffic on TCP ports 80, 443 and 8140 for Foreman and Puppet to function correctly
- The host running Foreman may be running selinux in Enforcing mode, but you must first install the ruby193-foreman-selinux package. Both the OpenStack controller and compute nodes can also run in enforcing mode if you install the openstack-selinux package. You must also manually set a boolean on the controller node: setsebool -P httpd_can_network_connect on
