# = 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.

#

# == Variables:

#

# [*rpm*]

#   The name of the rpm to install

#

# [*rpm_version*]

#   (Optional) - The version to install (default: latest)

#

# [*install_root*]

#   (Optional) - The rpm installation root (default: / )

#

# [*predeploy_customcommand*]

#   (Optional) -  Full path with arguments of an eventual custom command to

#   execute before the deploy. The command is executed as $predeploy_user.

#

# [*predeploy_user*]

#   (Optional) - The user to be used to execute the $predeploy_customcommand.

#   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

#   stop during deploy. By default is blank. Example: "apache puppet monit".

#

# [*firewall_src_ip*]

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

#   during a deploy.

#

# [*firewall_dst_port*]

#   (Optional) - The local port to block from the loadbalancer during deploy

#   (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*]

#   (Optional) - The (space separated) email(s) to notify of deploy/rollback

#   operations. If none is specified, no email is sent.

#

# [*run_checks*]

#   (Optional) - If you want to run local puppi checks before and after the

#   deploy procedure. Default: "true".

#

# [*checks_required*]

#   (Optional) - Set to "true" if you want to block the installation if

#   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

#   and the new files. If they are the same the deploy is not done.

#

# [*auto_deploy*]

#   (Optional) - If you want to automatically run this puppi deploy when

#   Puppet runs. Default: 'false'

#
