# storing the image to jlgrock/jboss-eap.  If you drop extra WARs
# into the install directory, you can create a custom deployment.
# It is suggested that you don't use this script though, as you'll
# want to store this image to something other than jlgrock/jboss-eap.
# For example, you can put webapp.war in there and create an instance
