Overview

The data_fragments module lets you construct data files from multiple ordered fragments of data

Easy example

To start using data_fragments you need to create:

A data_file resource for the final file.
One or more data_fragments.

A minimal example might be:

data_file { '/tmp/file':
  ensure => present,
  tag    => 'demo',
}

data_fragment { 'tmpfile':
  target  => '/tmp/file',
  content => 'test contents',
  order   => '01'
  tag     => 'demo',
}

Usage

Check the examples directory for example uses of json, json-pretty, and yaml.

Types

Type: `data_file`

`backup`

Data type: String, Boolean.

Specifies whether (and how) to back up the destination file before overwriting it. Your value gets passed on to Puppet's native file resource for execution. Valid options: true, false, or a string representing either a target filebucket or a filename extension beginning with ".".

Default value: 'puppet'.

`ensure`

Data type: String.

Specifies whether the destination file should exist. Setting to 'absent' tells Puppet to delete the destination file if it exists, and negates the effect of any other parameters. Valid options: 'present' and 'absent'.

Default value: 'present'.

`ensure_newline`

Data type: Boolean.

Specifies whether to add a line break at the end of each fragment that doesn't already end in one. Valid options: true and false.

Default value: false.

`group`

Data type: String, Integer.

Specifies a permissions group for the destination file. Valid options: a string containing a group name.

Default value: undef.

`mode`

Data type: String.

Specifies the permissions mode of the destination file. Valid options: a string containing a permission mode value in octal notation.

Default value: '0644'.

`order`

Data type: String.

Specifies a method for sorting your fragments by name within the destination file. Valid options: 'alpha' (e.g., '1, 10, 2') or 'numeric' (e.g., '1, 2, 10').

You can override this setting for individual fragments by adjusting the order parameter in their data_fragment declarations.

Default value: 'numeric'.

`owner`

Data type: String, Integer.

Specifies the owner of the destination file. Valid options: a string containing a username.

Default value: undef.

`path`

Data type: String.

Specifies a destination file for the combined fragments. Valid options: a string containing an absolute path. Default value: the title of your declared resource.

Default value: namevar.

`replace`

Data type: Boolean.

Specifies whether to overwrite the destination file if it already exists. Valid options: true and false.

Default value: true.

`tag`

Data type: String.

Required. Specifies a unique tag reference to collect all data_fragments with the same tag.

`validate_cmd`

Data type: String

Specifies a validation command to apply to the destination file. Requires Puppet version 3.5 or newer. Valid options: a string to be passed to a file resource.

Default value: undef.

`format`

Data type: String

Specify what data type to merge the fragments as. Valid options: 'plain', 'yaml', 'json', 'json-pretty'.

Default value: plain.

`force`

Data type: Boolean

Specifies whether to merge data structures, keeping the values with higher order. Valid options: true and false.

Default value: false.

Type: `data_fragment`

`content`

Data type: String.

Supplies the content of the fragment. Note: You must supply either a content parameter or a source parameter. Valid options: a string.

Default value: undef.

`order`

Data type: String, Integer.

Reorders your fragments within the destination file. Fragments that share the same order number are ordered by name. Valid options: a string (recommended) or an integer.

Default value: '10'.

`source`

Data type: String.

Specifies a file to read into the content of the fragment. Note: You must supply either a content parameter or a source parameter. Valid options: a string or an array, containing one or more Puppet URLs.

Default value: undef.

`tag`

Data type: String.

Required. Specifies a unique tag to be used by data_file to reference and collect content.

`target`

Data type: String.

Required. Specifies the destination file of the fragment. Valid options: a string containing the path or title of the parent data_file resource.

Types in this module release

data_file

Gets all the file fragments and puts these into the target file. This will mostly be used with exported resources.

example:
  Data_fragment <<| tag == 'unique_tag' |>>

  data_file { '/tmp/file':
    tag            => 'unique_tag', # Mandatory
    path           => '/tmp/file',  # Optional. If given it overrides the resource name
    owner          => 'root',       # Optional. Default to undef
    group          => 'root',       # Optional. Default to undef
    mode           => '0644'        # Optional. Default to undef
    order          => 'numeric'     # Optional, Default to 'numeric'
    ensure_newline => false         # Optional, Defaults to false
  }

Parameters
backup	Controls the filebucketing behavior of the final file and see File type reference for its use.
ensure
ensure_newline	Whether to ensure there is a newline after each fragment.
force	Forcibly merge duplicate keys keeping values of the highest order.
format	What data type to merge the fragments as.
group	Desired file group.
mode	Desired file mode.

seluser
show_diff
tag	Tag reference to collect all data_fragment's with the same tag
validate_cmd	Validates file.

data_fragment

Create a data_fragment to be used by a data_file. the data_fragment type creates a file fragment to be collected based on the tag. The example is based on exported resources.

Example:
@@data_fragment { "uniqe_name_${::fqdn}":
  tag => 'unique_name',
  order => 10, # Optional. Default to 10
  content => 'some content' # OR
  content => template('template.erb') # OR
  source  => 'puppet:///path/to/file'
}

Parameters
content	Content
name	Unique name
order	Order
source	Source
tag	Tag name to be used by data_file to collect all data_fragments by tag name

      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade

      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the

      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
