  -D  Debug logging
  -e  Do not launch environment deployment

  -F  Do only create a Salt master

$(notify_i "Description:" 2)
Deploys the Fuel@OPNFV stack on the indicated lab resource.

This script provides the Fuel@OPNFV deployment abstraction.
It depends on the OPNFV official configuration directory/file structure
and provides a fairly simple mechanism to execute a deployment.

$(notify_i "Input parameters to the build script are:" 2)
-b Base URI to the configuration directory (needs to be provided in URI style,
   it can be a local resource: file:// or a remote resource http(s)://).
   A POD Descriptor File (PDF) and its Installer Descriptor File (IDF)
   companion should be available at:
   <base-uri>/labs/<lab-name>/<pod-name>.yaml
   <base-uri>/labs/<lab-name>/idf-<pod-name>.yaml
   The default is using the git submodule tracking 'OPNFV Pharos' in
   <./mcp/scripts/pharos>.
   An example config is provided inside current repo in
   <./mcp/config>, automatically linked as <./mcp/scripts/pharos/labs/local>.
-d Dry-run - Produce deploy config files, but do not execute deploy
-D Debug logging - Enable extra logging in sh deploy scripts (set -x)
-e Do not launch environment deployment
-E Remove existing VCP VMs. It will destroy and undefine all VCP VMs
   currently defined on cluster KVM nodes. If specified twice (e.g. -E -E),
   baremetal nodes (VCP too, implicitly) will be removed, then reprovisioned.
   Only applicable for baremetal deploys.
-f Deploy on existing Salt master. It will skip infrastructure VM creation,
   but it will still sync reclass configuration from current repo to Salt
   Master node. If specified twice (e.g. -f -f), config sync will also be
   skipped.
-F Do only create a Salt master
-h Print this message and exit
-L Deployment log path and name, eg. -L /home/jenkins/job.log.tar.gz
-l Lab name as defined in the configuration directory, e.g. lf
-p POD name as defined in the configuration directory, e.g. pod2
-P Skip installing dependency distro packages on current host
   This flag should only be used if you have kept back older packages that
   would be upgraded and that is undesirable on the current system.
   Note that without the required packages, deploy will fail.
-s Deployment-scenario, this points to a short deployment scenario name, which
   has to be defined in config directory (e.g. os-odl-nofeature-ha).
-S Storage dir for VM images, default is mcp/deploy/images

$(notify_i "[NOTE] sudo & virsh priviledges are needed for this script to run" 3)

Example:

$(notify_i "sudo $(basename "$0") \\
  -b file:///home/jenkins/securedlab \\
  -l lf -p pod2 \\
  -s os-odl-nofeature-ha" 2)
