If anyone is interested in setting up their system to automatically (or manually) sign their git commits with their GPG key, here are the steps:

Generate and add your key to GitHub
$ git config --global commit.gpgsign true ([OPTIONAL] every commit will now be signed)
$ git config --global user.signingkey ABCDEF01 (where ABCDEF01 is the fingerprint of the key to use)
$ git config --global alias.logs "log --show-signature" (now available as $ git logs)
$ git config --global alias.cis "commit -S" (optional if global signing is false)
$ echo "Some content" >> example.txt
$ git add example.txt
$ git cis -m "This commit is signed by a GPG key." (regular commit will work if global signing is enabled)

Requirements

no upfront installation/agents on remote/slave machines - ssh should be enough
application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
configuration templating
environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
deployment process run from Jenkins

	### An example of building a TensorFlow model from R using rPython ###
	# For this script you need to
	# 1. Have python 2.7 installed.
	# 2. Install the rPython package in R.
	# 3. Install Google's TensorFlow library as per these instructions:
	# http://www.tensorflow.org/get_started/os_setup.md#binary_installation

	### Here is how to setup and run a trivial TensorFlow model ###

	# Load TensorFlow (I couldn't get this to work without setting sys.argv... )

	USER='admin'
	PASS='admin'
	CLUSTER='dev'
	HOST=$(hostname -f):8080

	function start(){
	curl -u $USER:$PASS -i -H 'X-Requested-By: ambari' -X PUT -d \

	### SYMBOLIC LINK FILES
	# Create a new symbolic link file named MySymLinkFile.txt in C:\Temp which links to $pshome\profile.ps1
	cd C:\Temp
	New-Item -ItemType SymbolicLink -Name MySymLinkFile.txt -Target $pshome\profile.ps1 # File
	# Target is an alias to the Value parameter

	# Equivalent to above
	New-Item -ItemType SymbolicLink -Path C:\Temp -Name MySymLinkFile.txt -Value $pshome\profile.ps1

	# Equivalent to above
