#. 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|clean]
#. Status: this is a work in progress, under test.

# workaround for virt-customize warning: libguestfs: warning: current user is not a member of the KVM group (group ID 121). This user cannot access /dev/kvm, so libguestfs may run very slowly. It is recommended that you 'chmod 0666 /dev/kvm' or add the current user to the KVM group (you might need to log out and log in again).
