# Deploy script to install provisioning server for OPNFV Apex
# author: Dan Radez (dradez@redhat.com)
# author: Tim Rozet (trozet@redhat.com)
#
# Based on RDO Manager http://www.rdoproject.org
#
# Pre-requisties:
#  - Supports 3 or 4 network interface configuration
#  - Target system must be RPM based
#  - Provisioned nodes expected to have following order of network connections (note: not all have to exist, but order is maintained):
#    eth0- admin network
#    eth1- private network (+storage network in 3 NIC config)
#    eth2- public network
#    eth3- storage network
#  - script assumes /24 subnet mask
