# This job tests the functionality of the openstack-operator to remove a
# compute node.
#
# This job was created to satisfy:
# https://issues.redhat.com/browse/osprh-5747

# Since jobs use different names for their OpenStackDataPlaneNodeSet's, we need to dynamically
# determine the name of the currently deployed one
