Puppet Concat Module

This is a module that provides a native type for performing multi-part file concatenation, generally referred to by the Puppet Labs team as the File Fragment Pattern.

The concept is based on ideas that R.I. Pienaar describes on his Building files from fragments in Puppet page.

Installation

The recommended way to install this package is either through the Puppet module manager or via RPM. A spec file has been included that can be used to create an RPM if required.

This module is known to be compatible with Puppet 2.6.

Basic Usage

This module has been designed to be quite flexible but follows the basic pattern of specifying file fragments and subsequently building a target file.

See the comments in the code for the definition of all options.

concat_build { "identifier":
  order => ['*.tmp'],
  target => '/tmp/test'
}

concat_fragment { "identifier+01.tmp":
  content => "Some random stuff"
}

concat_fragment { "identifier+02.tmp":
  content => "Some other random stuff"
}

Appending without newlines

If, for example, you wanted your fragments to join together to be a comma-separated list, you can achieve this by doing:

concat_build { "identifier":
  order => ['*.tmp'],
  target => '/tmp/test',
  file_delimiter => ",",
  append_newline => false
}

Chained Builds

There are times where you're going to want to chain multiple concat fragment builds into a single entity. Multi-part or INI-style files is generally where this comes into play.

An example of this type of build is as follows:

concat_build { "identifier":
  order => ['*.tmp'],
  target => '/tmp/test'
}

concat_fragment { "identifier+01.tmp":
  content => "Some random stuff"
}

concat_fragment { "identifier+02.tmp":
  content => "Some other random stuff"
}

concat_build { "subtest":
  parent_build => "identifier",
  target => "/var/lib/puppet/concat/fragments/identifier/subtest.tmp"
}

concat_fragment { "subtest+sub1":
  content => "Sub-build stuff"
}

concat_fragment { "subtest+sub2":
  content => "More sub-build stuff"
}

Notes

Concat fragments are stored under Puppet[:vardir]/concat/fragments.
