# Sample YAML representation of a flexible pipeline for use with the
# Jenkins Build Pipeline Plugin
# (https://wiki.jenkins-ci.org/display/JENKINS/Build+Pipeline+Plugin)
# The pipeline is defined at the project level, using job-specific variable
# substitution to specify the next job in the pipeline ('pipeline-next') 
# for each job.
#
# This example defines the skeleton of two deployment pipelines: one for
# a 'base_os' subsystem to three chef servers, and the second to
# a 'database' subsystem to two chef servers.
# 
# The pipeline uses an automatically-executed job in '{subsys}-prepare'
# (using the Parameterized Trigger Plugin - 
# https://wiki.jenkins-ci.org/display/JENKINS/Parameterized+Trigger+Plugin),
# and manually-triggered jobs using the Pipeline publisher (e.g.
# '{subsys}-initialise').
#
# Note how each project defines a different pipeline, with a different
# length, but re-uses the same job templates.
