#    SCRIPT IS PROVIDED TO CREATE MESSAGESIGHT DEMO ENVIRONMENT.
#    DO NOT USE THIS SCRIPT TO CREATE A PRODUCTION OR TEST ENVIRONMENT.
# ==============================================================================
#

#
# This script can be used to build following docker images for 
# IBM IoT MessageGateway 5.0.0 demos:
#
# - MessageGateway Server 
#   docker image name: imaserver
#   docker image version: 5.0
#
# - MessageGateway WebUI
#   docker image name: imawebui
#   docker image version: 5.0
#
# - MessageGateway Bridge
#   docker image name: imabridge
#   docker image version: 5.0
#
# 
# Prereq steps:
#
# - Install Docker Community Edition on your system. For details refer to:
#   https://docs.docker.com/install/
#
# - Create a directory pkgs
#
# - Download the latest install images of IBM MessageGateway Server, WebUI, and Bridge
#   from IBM FixCentral or Pasport advantage and copy the files in the pkgs directory.
