Description of problem: cns-deploy -n storage-project -g cns-topology.json
Welcome to the deployment tool for GlusterFS on Kubernetes and OpenShift.
                     
Before getting started, this script has some requirements of the execution
environment and of the container platform that you should verify.
                     
The client machine that will run this script must have:
 * Administrative access to an existing Kubernetes or OpenShift cluster
 * Access to a python interpreter 'python'
 * Access to the heketi client 'heketi-cli'
                     
Each of the nodes that will host GlusterFS must also have appropriate firewall
rules for the required GlusterFS ports:
 * 2222  - sshd (if running GlusterFS in a pod)
 * 24007 - GlusterFS Daemon
 * 24008 - GlusterFS Management
 * 49152 to 49251 - Each brick for every volume on the host requires its own
   port. For every new brick, one new port will be used starting at 49152. We
   recommend a default range of 49152-49251 on each host, though you can adjust
   this to fit your needs.
                     
In addition, for an OpenShift deployment you must:
 * Have 'cluster_admin' role on the administrative account doing the deployment
 * Add the 'default' and 'router' Service Accounts to the 'privileged' SCC
 * Have a router deployed that is configured to allow apps to access services
   running in the cluster
                     
Do you wish to proceed with deployment?
