The simplest way is just to include a conditional in whatever script etc you're applying via NodeExtraConfigPost, you can, for example, look at the hostname of the box to derive the role, as compute is always called overcloud-compute-N (or whatever you've set via the ComputeHostnameFormat parameter, which you can make unique for computes). There are probably several other ways you can determine the node type/role but that's one of the simplest. Hope that helps, Steve
