+# Clean up DCAE during ONAP uninstall
+#
+# When helm delete is being used to uninstall all of ONAP, helm does
+# not know about k8s entities that were created by Cloudify Manager.
+# This script--intended to run as a preUninstall hook when Cloudify Manager itself
+# is undeleted--uses Cloudify to clean up the k8s entities deployed by Cloudify.
+#
+# Rather than using the 'cfy uninstall' command to run a full 'uninstall' workflow
+# against the deployments, this script uses 'cfy executions' to run a 'stop'
+# stop operation against the nodes in each deployment.  The reason for this is that,
+# at the time this script run, we have no# guarantees about what other components are
+# still running.  In particular, a full 'uninstall' will cause API requests to Consul
+# and will raise RecoverableErrors if it cannot connect.  RecoverableErrors send Cloudify
+# into a long retry loop.  Instead, we invoke only the 'stop'
+# operation on each node, and the 'stop' operation uses the k8s API (guaranteed to be
+# present) but not the Consul API.
+#
+# Note that the script finds all of the deployments known to Cloudify and runs the
+# 'stop' operation on every node
+# The result of the script is that all of the k8s entities deployed by Cloudify
+# should be destroyed.  Cloudify Manager itself isn't fully cleaned up (the deployments and
+# blueprints are left), but that doesn't matter because Cloudify Manager will be
+# destroyed by Helm.
