5.0 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below
is for guidance only and neither of
these methods should be considered
an endorsement by Puppet.

Overview

The concat module lets you construct files from multiple ordered fragments of text.

Module Description

The concat module lets you gather concat::fragment resources from your other modules and order them into a coherent file through a single concat resource.

Beginning with concat

To start using concat you need to create:

  • A concat{} resource for the final file.
  • One or more concat::fragment{}s.

A minimal example might be:

concat { '/tmp/file':
  ensure => present,
}

concat::fragment { 'tmpfile':
  target  => '/tmp/file',
  content => 'test contents',
  order   => '01'
}

Usage

Maintain a list of the major modules on a node

To maintain an motd file that lists the modules on one of your nodes, first create a class to frame up the file:

class motd {
  $motd = '/etc/motd'

  concat { $motd:
    owner => 'root',
    group => 'root',
    mode  => '0644'
  }

  concat::fragment { 'motd_header':
    target  => $motd,
    content => "\nPuppet modules on this server:\n\n",
    order   => '01'
  }

  # let local users add to the motd by creating a file called
  # /etc/motd.local
  concat::fragment { 'motd_local':
    target => $motd,
    source => '/etc/motd.local',
    order  => '15'
  }
}

# let other modules register themselves in the motd
define motd::register (
  $content = "",
  $order   = '10',
) {
  if $content == "" {
    $body = $name
  } else {
    $body = $content
  }

  concat::fragment { "motd_fragment_$name":
    target  => '/etc/motd',
    order   => $order,
    content => "    -- $body\n"
  }
}

Then, in the declarations for each module on the node, add motd::register{ 'Apache': } to register the module in the motd.

class apache {
  include apache::install, apache::config, apache::service

  motd::register { 'Apache': }
}

These two steps populate the /etc/motd file with a list of the installed and registered modules, which stays updated even if you just remove the registered modules' include lines. System administrators can append text to the list by writing to /etc/motd.local.

When you're finished, the motd file will look something like this:

  Puppet modules on this server:

    -- Apache
    -- MySQL

  <contents of /etc/motd.local>
