delete_shiftstack.yml

---
# Playbook to delete OCP cluster(s) and resources from OpenStack.
#
# Multiple clusters can be deleted at once by specifing what index to start and
# the count of clusters to delete.
#
# Example Usage:
#
# time ansible-playbook delete_shiftstack.yml -e "ocp_cluster_index_start=0 ocp_cluster_index_count=8"
