Jenkins CI

Check the disk space with a self contain script based on Ruby Execute this shell scritp on remote host using ssh

rm check_disk.rb

tee -a check_disk.rb <<EOF 
# parse mount point VM (TODO customize for your machine)

If the parent script runs with fail on error switch: tcsh -e but a sub script issue a exit code non zero. Then the parent will fail like a Jenkins pipeline, Bamboo job or else.

This switch allows easy pipeline debug by stopping the script when exit code > 0

	#
	# Rake is amazing automation tools based on Ruby.
	# Rake open source documentation is pretty limited relative to the tool capability.
	#
	# It's better than Makefile because it's more dynamic.
	# while Makefile are pretty flexible, there are a lot of builtin rules
	# and conventions that must be follow.
	# This make pretty hard to learn, debug and scaling can be frustrating.
