Description

The augeas_core module is used to manage configuration files using Augeas. This module is suitable for any host for which there are Augeas libraries and ruby bindings.

Setup

Setup Requirements

The augeas libraries and ruby bindings must be installed in order to use this module. If you are using puppet-agent packages, then those prerequisites are already satisfied for most platforms.

Beginning with augeas_core

To manage a configuration file using augeas, use the following code:

augeas { 'add_services_entry':
  context => '/files/etc/services',
  incl    => '/etc/services',
  lens    => 'Services.lns',
  changes => [
    'ins service-name after service-name[last()]',
    'set service-name[last()] "Doom"',
    'set service-name[. = "Doom"]/port "666"',
    'set service-name[. = "Doom"]/protocol "udp"'
  ]
}

Usage

Please see REFERENCE.md for the reference documentation and examples for details on usage.

Reference

Please see REFERENCE.md for the reference documentation.

This module is documented using Puppet Strings.

For a quick primer on how Strings works, please see this blog post or the README.md for Puppet Strings.

To generate documentation locally, run the following command:

bundle install
bundle exec puppet strings generate ./lib/**/*.rb

This command will create a browsable _index.html file in the doc directory. The references available here are all generated from YARD-style comments embedded in the code base. When any development happens on this module, the impacted documentation should also be updated.

Limitations

This module is only available on platforms that have augeas libraries and ruby bindings installed.

Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can't access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

For more information, see our module contribution guide.

Reference

Resource types

augeas: Apply a change or an array of changes to the filesystem using the augeas tool.

Resource types

`augeas`

Requires:

Augeas
The ruby-augeas bindings

Examples

Sample usage with a string:


augeas { "test1":
  context => "/files/etc/sysconfig/firstboot",
  changes => "set RUN_FIRSTBOOT YES",
  onlyif  => "match other_value size > 0",
}

Sample usage with an array and custom lenses:


augeas { "jboss_conf":
  context   => "/files",
  changes   => [
      "set etc/jbossas/jbossas.conf/JBOSS_IP $ipaddress",
      "set etc/jbossas/jbossas.conf/JAVA_HOME /usr",
    ],
  load_path => "$/usr/share/jbossas/lenses",
}

Properties

The following properties are available in the augeas type.

`returns`

The expected return code from the augeas command. Should not be set.

Default value: 0

Parameters

The following parameters are available in the augeas type.

changes
context
force
incl
lens
load_path
name
onlyif
provider
root
show_diff
type_check

`changes`

The changes which should be applied to the filesystem. This can be a command or an array of commands. The following commands are supported:

set <PATH> <VALUE> --- Sets the value VALUE at location PATH
setm <PATH> <SUB> <VALUE> --- Sets multiple nodes (matching SUB relative to PATH) to VALUE
rm <PATH> --- Removes the node at location PATH
remove <PATH> --- Synonym for rm
clear <PATH> --- Sets the node at PATH to NULL, creating it if needed
clearm <PATH> <SUB> --- Sets multiple nodes (matching SUB relative to PATH) to NULL
touch <PATH> --- Creates PATH with the value NULL if it does not exist
ins <LABEL> (before|after) <PATH> --- Inserts an empty node LABEL either before or after PATH.
insert <LABEL> <WHERE> <PATH> --- Synonym for ins
mv <PATH> <OTHER PATH> --- Moves a node at PATH to the new location OTHER PATH
move <PATH> <OTHER PATH> --- Synonym for mv
rename <PATH> <LABEL> --- Rename a node at PATH to a new LABEL
defvar <NAME> <PATH> --- Sets Augeas variable $NAME to PATH
defnode <NAME> <PATH> <VALUE> --- Sets Augeas variable $NAME to PATH, creating it with VALUE if needed

If the context parameter is set, that value is prepended to any relative PATHs.

`context`

Optional context path. This value is prepended to the paths of all changes if the path is relative. If the incl parameter is set, defaults to /files + incl; otherwise, defaults to the empty string.

Default value: ''

`force`

Optional command to force the augeas type to execute even if it thinks changes will not be made. This does not override the onlyif parameter.

Default value: false

`incl`

Load only a specific file, such as /etc/hosts. This can greatly speed up the execution the resource. When this parameter is set, you must also set the lens parameter to indicate which lens to use.

`lens`

Use a specific lens, such as Hosts.lns. When this parameter is set, you must also set the incl parameter to indicate which file to load. The Augeas documentation includes a list of available lenses.

`load_path`

Optional colon-separated list or array of directories; these directories are searched for schema definitions. The agent's $libdir/augeas/lenses path will always be added to support pluginsync.

Default value: ''

`name`

namevar

The name of this task. Used for uniqueness.

`onlyif`

Optional augeas command and comparisons to control the execution of this type.

Note: values is not an actual augeas API command. It calls match to retrieve an array of paths in <MATCH_PATH> and then get to retrieve the values from each of the returned paths.

Supported onlyif syntax:

get <AUGEAS_PATH> <COMPARATOR> <STRING>
values <MATCH_PATH> include <STRING>
values <MATCH_PATH> not_include <STRING>
values <MATCH_PATH> == <AN_ARRAY>
values <MATCH_PATH> != <AN_ARRAY>
match <MATCH_PATH> size <COMPARATOR> <INT>
match <MATCH_PATH> include <STRING>
match <MATCH_PATH> not_include <STRING>
match <MATCH_PATH> == <AN_ARRAY>
match <MATCH_PATH> != <AN_ARRAY>

where:

AUGEAS_PATH is a valid path scoped by the context
MATCH_PATH is a valid match syntax scoped by the context
COMPARATOR is one of >, >=, !=, ==, <=, or <
STRING is a string
INT is a number
AN_ARRAY is in the form ['a string', 'another']

Default value: ''

`provider`

The specific backend to use for this augeas resource. You will seldom need to specify this --- Puppet will usually discover the appropriate provider for your platform.

`root`

A file system path; all files loaded by Augeas are loaded underneath root.

Default value: /

`show_diff`

Valid values: true, false, yes, no

Whether to display differences when the file changes, defaulting to true. This parameter is useful for files that may contain passwords or other secret data, which might otherwise be included in Puppet reports or other insecure outputs. If the global show_diff setting is false, then no diffs will be shown even if this parameter is true.

Default value: true

`type_check`

Valid values: true, false

Whether augeas should perform typechecking. Defaults to false.

Default value: false

      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the

      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      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
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      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
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      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.
