# = Define puppi::project::yum
|
|
#
|
|
# This is a shortcut define to build a puppi project for the
|
|
# deploy of applications packaged as rpm and retrievable via yum
|
|
#
|
|
# It uses different "core" defines (puppi::project, puppi:deploy (many),
|
|
# puppi::rollback (many)) to build a full featured template project for
|
|
# automatic deployments.
|
|
# If you need to customize it, either change the template defined here or
|
|
# build up your own custom ones.
|
|
#

# By default is the same of $user.
|
|
#
|
|
# [*predeploy_priority*]
|
|
# (Optional) - The priority (execution sequence number) that defines when,
|
|
# during the deploy procedure, the $predeploy_customcommand is executed
|
|
# Default: 39 (immediately before the copy of files on the deploy root).
|
|
#
|
|
# [*postdeploy_customcommand*]
|
|
# (Optional) - Full path with arguments of an eventual custom command to
|
|
# execute after the deploy. The command is executed as $postdeploy_user.
|
|
#
|
|
# [*postdeploy_user*]
|
|
# (Optional) - The user to be used to execute the $postdeploy_customcommand.
|
|
# By default is the same of $user.
|
|
#
|
|
# [*postdeploy_priority*]
|
|
# (Optional) - The priority (execution sequence number) that defines when,
|
|
# during the deploy procedure, the $postdeploy_customcommand is executed
|
|
# Default: 41 (immediately after the copy of files on the deploy root).
|
|
#
|
|
# [*disable_services*]
|
|
# (Optional) - The names (space separated) of the services you might want to

|
# (Optional) - The IP address of a loadbalancer you might want to block out
|
|
# during a deploy.
|

#
|
|
# [*firewall_dst_port*]

|
|
# (Default all).
|
|
#
|
|
# [*firewall_delay*]
|
|
# (Optional) - A delay time in seconds to wait after the block of
|
|
# $firewall_src_ip. Should be at least as long as the loadbalancer check
|
|
# interval for the services stopped during deploy (Default: 1).
|
|
#
|
|
# [*report_email*]
|

|
# preliminary checks fail. Default: "false"
|
|
#
|
|
# [*always_deploy*]
|
|
# (Optional) - If you always deploy what has been downloaded. Default="yes",
|
|
# if set to "no" a checksum is made between the files previously downloaded

|
|
# Puppet runs. Default: 'false'
