# This playbook is used to clean up any host and service entries in IPA
# when a stack is deleted.  It should be run on the undercloud against the
# inventory generated by tripleo-ansible-inventory.
#
# In particular, we expect the node on which this playbook is run to be an
# IPA client and to have a valid keytab
