* `/etc/ansible/foreman.ini`
* Current directory of your inventory script.
* `FOREMAN_INI_PATH` environment variable.

Variables and Parameters

The data returned from Foreman for each host with a "openshift-role" host parameter is stored in a OpenShift ansible inventory group structure. The groupnames are created from the "openshift-role" comma seperated values, for example: openshift-role=masters,etcd,nodes
