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

# A simple ruby daemon that you copy and change as needed.
# 
# === How does it work?
#
# All this program does is fork the current process (creates a copy of
# itself) then exits, the fork (child process) then goes on to run your
# daemon code. In this example we are just running a while loop with a
