# SWARM_MANAGER_COUNT - The number of managers in the swarm cluster. This is
#               used to limit the number of instances of some of the 
#               service instances for smaller clusters. 
#               [ NOTE - currently this parameter is handled via a Jinga2
#                 templating capability, because as of 17.09.0-ce Docker
#                 cannot use and environment variable for the `replicas`
#                 attribute on a container. ]
# REGISTRY      - The docker registry host from which images should be
#                 pulled, i.e. `private-reg.com:5000/`. If specified
#                 it should end in a `/`. Defaults to empty.
# REPOSITORY    - The docker repository name from which voltha specific
#                 images should be pulled, i.e. `voltha/`. If specified it
#                 should end in a `/`. Defaults to empty.
# TAG           - The tag that should be used when referencing VOLTHA docker
#                 images, defaults to `latest`.
# CONSUL_ROOT   - The local path on which the consul/data and consul/config
#                 directories should be created. Defaults to `/var/local`.
# VOLTHA_LOGS   - The location into which `fluentd` should writes logs.
#                 Defaults to `/var/log`.
# RADIUS_ROOT   - The location in which the `data/clients.conf` and 
#                 `data/users` configuration files can be found. Defaults
#                 to `/var/local`.
# DOCKER_HOST_IP -
# ZK_TAG        - The tag that should be used when referencing the ZooKeeper
#                 docker image. Defaults to `latest`.
# KAFKA_TAG     - The tag that should be used when referencing the Kafka
#                 docker image. Default to `1.0.0`.
# CONSUL_TAG    - The tag that should be used when referencing the Consul
#                 docker image. Defaults to `0.9.2`.
# RADIUS_TAG    - The tag that should be used when referencing the FreeRADIUS
#                 docker image. Defaults to `latest`.
