#. What this is: Setup script for Cloudify use with Kubernetes.
#. Prerequisites:
#. - Kubernetes cluster installed per k8s-cluster.sh (in this repo)
#. Usage:
#. From a server with access to the kubernetes master node:
#. $ git clone https://gerrit.opnfv.org/gerrit/models ~/models
#. $ scp -r ~/models/tools/cloudify ubuntu@<k8s-master>:/home/ubuntu/.
#. <k8s-master>: IP or hostname of kubernetes master server
#. $ ssh -x ubuntu@<k8s-master> cloudify/k8s-cloudify.sh prereqs
#. prereqs: installs prerequisites and configures ubuntu user for kvm use
#. $ ssh -x ubuntu@<k8s-master> bash cloudify/k8s-cloudify.sh setup
#. setup: installs cloudify CLI and Manager
#. $ source ~/models/tools/cloudify/k8s-cloudify.sh demo <start|stop> <k8s-master>
#. demo: control demo blueprint
#. start|stop: start or stop the demo
#. <k8s-master>: IP or hostname of kubernetes master server
#. $ ssh -x ubuntu@<k8s-master> bash cloudify/k8s-cloudify.sh clean
#. clean: uninstalls cloudify CLI and Manager
#. Status: this is a work in progress, under test.
