#!/bin/bash
# This is a shell script to create customised docker containers for NGINX and Nexus.
# The script has been tested on Docker for Mac but should work with all versions of Docker or Docker Toolbox.
# The script takes parameters to customise the directories and ports used by the two containers.
# Usage: create-docker-dev-containers.sh /path/to/nexus nexusPort /path/to/nginxconf /path/to/nginxhtml nginxPort

#Check that input parameters (/path/to/nexus, nexusPort, /path/to/nginxconf, /path/to/nginxhtml, nginxPort) are present. Otherwise return usage message and exit.
