#This script creates the Docker image (if not already created) and runs maven in the container
#1. Install Docker
#2. Checkout Ranger source and go to the root directory
#3. Run this script. If host is linux, then run this script as "sudo $0 ..."
#4. If you are running on Mac, then you don't need to use "sudo"
#5. To delete the image, run "[sudo] docker rmi ranger_dev"

#Usage: [sudo] ./build_ranger_using_docker.sh [-build_image] mvn  <build params>
#Example 1 (default no param): (mvn -Pall -DskipTests=true clean compile package install assembly:assembly)
#Example 2 (Regular build): ./build_ranger_using_docker.sh mvn -Pall clean install -DskipTests=true
#Example 3 (Recreate Docker image): ./build_ranger_using_docker.sh mvn -Pall -build_image clean install -DskipTests=true 
#Notes: To remove build image manually, run "docker rmi ranger_dev" or "sudo docker rmi ranger_dev"
