# this script is executed for kubernetes deployment. With Ansible deployment, only
# ovsdb-server gets launched and then the following workflow step will create
# an external bridge and plug an external interface. With Kubernetes we want to
# leverage its dynamic nature of automatic scaling up and down. It means all
# activities related to creating initial bridge, plugging external interface
# must be done by DaemonSet launched container.
