Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

puppet_compat Cookbook

Build Status
Cookbook Version

While doing migration from Puppet to Chef I can easily map all Puppet resources to the Chef ones. All except two:
- file_line
- ini_setting (pe_ini_setting)

These two just don't have a counterpart in the Chef world. This cookbook provides exactly these two resources as HWRP.

Requirements

This cookbook need iniparse GEM to be installed.

Platforms

  • Debian-family Linux Distributions
  • RedHat-family Linux Distributions
  • Fedora
  • openSUSE

Chef

  • Chef 12.1+
  • Chef 13+
  • Chef 14+

Recipes

  • default takes care that iniparse GEM used by the HWPR is installed

Usage

Just add to your cookbook metadata.rb

depends 'puppet_compat'

and you can use file_line and ini_setting resources in you recipes.

file_line

The file line resource has the same properties, like in puppet except it has action instead of ensure.

file_line 'Add a line' do
  path   '/tmp/test.cfg'
  line   'line: ADD'
end

file_line 'Delete with match' do
  path   '/tmp/test.cfg'
  match  '^todelete'
  match_for_absence true
  action :delete
end

file_line 'Delete the line' do
  path   '/tmp/test.cfg'
  line   'yetanother: delete'
  action :delete
enda

file_line 'Change one line with match' do
  path   '/tmp/test.cfg'
  match  '^tochange'
  line   'tochange: changed'
end

ini_setting

Usage of ini_setting is also pretty close to the Puppet one. Ensure is also replaced with action.
The only one addition - you may provide the format of parameter=value separator.
Although it is against INI standard some software is sensitive to it, so
param=value
or
param = value
for some software packeges is important. For these non-standard following software you cat provide separator property:

ini_setting 'Set option' do
  path      '/tmp/test.ini'
  section   'test'
  setting   'option_add'
  value     'added'
  separator '='
end
ini_setting 'Set option with spaces' do
  path      '/tmp/test.ini'
  section   'test'
  setting   'option_add'
  value     'added'
  separator ' = '
end

The rest of usage cases are selfexplanatory:

ini_setting 'Delete option' do
  path      '/tmp/test.ini'
  section   'test'
  setting   'option_two'
  action :delete
end
ini_setting 'Change option' do
  path      '/tmp/test.ini'
  section   'test'
  setting   'option_chg'
  value     'nice'
end
ini_setting 'Delete section' do
  path      '/tmp/test.ini'
  section   'bad_section'
  action    :delete
end

Known bug - the following resource will fail if file /tmp/test.ini does not contain any options without a section:

ini_setting 'Set option outside sections' do
  path      '/tmp/test.ini'
  setting   'option_add'
  value     'added'
end

This is caused by the bug in iniparse GEM, see:
https://github.com/antw/iniparse/issues/20

ini_setting extensions

Based on practical use of the ini_setting resource I've made some extensions, which are not supported by puppet version of the resource.
This extension is useful when you need to do a number of changes in ini file. In puppet inplementation it is usualy solved by calling
ini_settings using create_resources() function. For Chef implementation I've decided to make it easy: properties section and setting
may by a hash or array.

set multiple setting within one section

In this case you need to pass to setting property the hash of key-value pairs like this one:

default['settings_test'] = {
  'one' => 'a',
  'two' => 'b',
}

Property value should not be used in this case.

set multiple settings in multiple sections

In this case you need to pass to section property the hash, where keys are section names and values are hashes like in previous case.
For example:

default['sections_test'] = {
  'testsec1' => {
    'set1' => 10,
    'set2' => 20,
  },
  'testsec2' => {
    'set21' => 100,
    'set22' => 200,
  },
}

With both methods above it is possible to change existing settings/sections or add a new ones.

delete multiple settings within a section

Just pass to setting property array with the settings names that should be deleted

delete multiple settings in multiple sections

In this case you need to pass to section property the hash, where keys are section names and values are arrays with settings names to delete.

delete multiple sections

Also possible. For this pass to section property array with section names to be deleted.
