# = Define puppi::project::builder

#

# This is a shortcut define to build a puppi project for the deploy of web

# applications based on different sources: a war file, a tar file, a source dir,

# a list of files or a nexus maven repository

# 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:

#

# [*source*]

#   The full URL of the main file to retrieve.

#   Format should be in URI standard (http:// file:// ssh:// rsync://).

#

# [*source_type*]

#   The type of file that is retrieved. Accepted values: tarball, zip, list,

#   war, dir, maven-metadata.

#

# [*deploy_root*]

#   The destination directory where the retrieved file(s) are deployed.

#

# [*init_source*]

#   (Optional) - The full URL to be used to retrieve, for the first time,

#   the project files. They are copied directly to the $deploy_root

#   Format should be in URI standard (http:// file:// ssh:// svn://).

#

# [*magicfix*]

#   (Optional) - A string that is used as prefix or suffix according to the

#   context and the scripts used in the deploy procedure.

#

# [*user*]

#   (Optional) - The user to be used for deploy operations.

#

# [*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.

#

# [*backup*]

#   (Optional) - How backups of files are made. Default: "full". Options:

#   "full" - Make full backup of the deploy_root before making the deploy

#   "diff" - Backup only the files that are going to be deployed. Note that

#     in order to make reliable rollbacks of versions older that the latest

#     you've to individually rollback every intermediate deploy

#   "false" - Do not make backups. This disables the option to make rollbacks

#

# [*backup_rsync_options*]

#   (Optional) - The extra options to pass to rsync for backup operations. Use

#   it, for example, to exclude directories that you don't want to archive.

#   IE: "--exclude .snapshot --exclude cache --exclude www/cache".

#

# [*backup_retention*]

#   (Optional) - Number of backup archives to keep. (Default 5).

#   Lower the default value if your backups are too large and may fill up the

#   filesystem.

#

# [*run_checks*]

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

#   deploy procedure. Default: "true".

#

# [*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.

#

# == Usage

# A sample deploy of a zip with custom postdeploy command and mail notification

# puppi::project::builder { "cms":

#   source                   => "http://repo.example42.com/deploy/cms/cms.zip",

#   source_type              => "zip",

#   user                     => "root",

#   deploy_root              => "/var/www",

#   postdeploy_customcommand => "chown -R www-data /var/www/files",

#   postdeploy_user          => "root",

#   postdeploy_priority      => "41",

#   report_email             => "sysadmins@example42.com",

#   enable                   => "true",

# }

#

# [*auto_deploy*]

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

#   Puppet runs. Default: 'false'

#
