# == Define: elasticsearch::service::init
|
|
#
|
|
# This class exists to coordinate all service management related actions,
|
|
# functionality and logical units in a central place.
|
|
#
|
|
# <b>Note:</b> "service" is the Puppet term and type for background processes
|
|
# in general and is used in a platform-independent way. E.g. "service" means
|
|
# "daemon" in relation to Unix-like systems.
|
|
#
|
|
#
|
|
# === Parameters
