#
#. What this is: Setup script for Cloudify use with Kubernetes.
#. Prerequisites:
#. - OPNFV Models repo cloned into ~/models, i.e.
#. git clone https://gerrit.opnfv.org/gerrit/models ~/models
#. - Kubernetes cluster installed per tools/kubernetes/demo_deploy.sh and
#. environment setup file ~/models/tools/k8s_env.sh as setup by demo_deploy.sh
#. - Kubernetes environment variables set per the k8s_env_*.sh created by
#. the demo_deploy.sh script (* is the hostname of the k8s master node).
#. Usage:
#. From a server with access to the kubernetes master node:
#. $ cd ~/models/tools/cloudify
#. $ scp -r ~/models/tools/* <user>@<k8s-master>:/home/<user>/.
#. <user>: username on the target host. Also used to indicate OS name.
#. <k8s-master>: IP or hostname of kubernetes master server
#. $ ssh -x <user>@<k8s-master> cloudify/k8s-cloudify.sh prereqs
#. <user>: username on the target host. Also used to indicate OS name.
#. prereqs: installs prerequisites and configures <user> user for kvm use
#. $ ssh -x <user>@<k8s-master> bash cloudify/k8s-cloudify.sh setup
#. <user>: username on the target host. Also used to indicate OS name.
#. setup: installs cloudify CLI and Manager
#. $ bash k8s-cloudify.sh demo <start|stop>
#. demo: control demo blueprint
#. start|stop: start or stop the demo
#. <k8s-master>: IP or hostname of kubernetes master server
#. $ bash k8s-cloudify.sh <start|stop> <name> <blueprint>
#. start|stop: start or stop the blueprint
#. name: name of the service in the blueprint
#. blueprint: name of the blueprint folder (in current directory!)
#. <k8s-master>: IP or hostname of kubernetes master server
#. $ bash k8s-cloudify.sh port <service> <k8s-master>
#. port: find assigned node_port for service
#. service: name of service e.g. nginx
#. <k8s-master>: IP or hostname of kubernetes master server
#. $ ssh -x <user>@<k8s-master> bash cloudify/k8s-cloudify.sh clean
#. <user>: username on the target host. Also used to indicate OS name.
#. clean: uninstalls cloudify CLI and Manager
#.
#. If using this script to start/stop blueprints with multiple k8s environments,
#. before invoking the script copy the k8s_env.sh script from the target
#. cluster and copy to ~/k8s_env.sh, e.g.
#. scp centos@sm-1:/home/centos/k8s_env.sh ~/k8s_env_sm-1.sh
#. cp ~/k8s_env_sm-1.sh ~/k8s_env.sh
#.
#. Status: this is a work in progress, under test.
