# What this is: Cleanup script for the Cloudify Manager running in an
# Unbuntu Xenial docker container.
#
# Status: this is a work in progress, under test.#
#
# Prerequisites:
#   $ bash /tmp/cloudify/cloudify-setup.sh
#
# How to use:
#   $ bash cloudify-clean.sh
#
# Extra commands useful in debugging:
# Delete all security groups created by Cloudify
# sg=($(openstack security group list|awk "/ security_group_local_security_group_/ { print \$2 }")); for id in ${sg[@]}; do openstack security group delete ${id}; done
# Delete all floating IPs
# flip=($(neutron floatingip-list|grep -v "+"|grep -v id|awk '{print $2}')); for id in ${flip[@]}; do neutron floatingip-delete ${id}; done
