Provision service catalog items of cluster

I learn about that out manageiq can support provisioning some complicated cluster, such as Hadoop or Openshift through service provision. This kind of provision normally need to do some configuration on each host of the cluster to after the vm provision to complete the task. So do what’s the standard procedure to provision a service catalog of cluster, especially how to do the configuration.

Peter McGowan’s book on Automation may help answer this question.
