# parse\_config\_file
|
|
|
|
Use the `parse_config_file` Chef InSpec audit resource to test arbitrary configuration files. It works in the same way as `parse_config`. Instead of using a command output, this resource works with files.
|
|
|
|
<br>
|
|
|
|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with Chef InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v1.0.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
A `parse_config_file` Chef InSpec audit resource block declares the location of the configuration file to be tested, and then which settings in that file are to be tested.
|
|
|
|
describe parse_config_file('/path/to/file', { data_config_option: value } ) do
|
|
its('setting') { should eq 1 }
|
|
end
|
|
|
|
or:
|
|
|
|
options = {
|
|
assignment_regex: /^\s*([^:]*?)\s*:\s*(.*?)\s*$/,
|
|
multiple_values: true
|
|
}
|
|
|
|
describe parse_config_file('path/to/file', options) do
|
|
its('setting') { should eq 1 }
|
|
end
|
|
|
|
where each test
|
|
|
|
* Must declare the location of the configuration file to be tested
|
|
* Must declare one (or more) settings to be tested
|
|
* May run a command to `stdout`, and then run the test against that output
|
|
* May use options to define how configuration data is to be parsed
|
|
|
|
<br>
|
|
|
|
## Options
|
|
|
|
This resource supports the following options for parsing configuration data. Use them in an `options` block stated outside of (and immediately before) the actual test:
|
|
|
|
options = {
|
|
assignment_regex: /^\s*([^:]*?)\s*:\s*(.*?)\s*$/,
|
|
multiple_values: true
|
|
}
|
|
describe parse_config_file('path/to/file', options) do
|
|
its('setting') { should eq 1 }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this Chef InSpec audit resource.
|
|
|
|
### Test a configuration setting
|
|
|
|
describe parse_config_file('/path/to/file.conf') do
|
|
its('PARAM_X') { should eq 'Y' }
|
|
end
|
|
|
|
### Use options, and then test a configuration setting
|
|
|
|
describe parse_config_file('/path/to/file.conf', { multiple_values: true }) do
|
|
its('PARAM_X') { should include 'Y' }
|
|
end
|
|
|
|
### Test a file with an ini-like structure (such as a yum.conf)
|
|
|
|
describe parse_config_file('/path/to/yum.conf') do
|
|
its('main') { should include('gpgcheck' => '1') }
|
|
end
|
|
|
|

## Matchers
|
|
|
|
For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
|
|
|
|
### assignment_regex
|
|
|
|
Use `assignment_regex` to test a key value using a regular expression:
|
|
|
|
'key = value'
|
|
|
|
may be tested using the following regular expression, which determines assignment from key to value:
|
|
|
|
assignment_regex: /^\s*([^=]*?)\s*=\s*(.*?)\s*$/
|
|
|
|
### comment_char
|
|
|
|
Use `comment_char` to test for comments in a configuration file:
|
|
|
|
comment_char: '#'
|
|
|
|
### key_values
|
|
|
|
Use `key_values` to test how many values a key contains:
|
|
|
|
key = a b c
|
|
|
|
contains three values. To test that value to ensure it only contains one, use:
|
|
|
|
key_values: 1
|
|
|
|
### multiple_values
|
|
|
|
Use `multiple_values` if the source file uses the same key multiple times. All values will be aggregated in an array:
|
|
|
|
# # file structure:
|
|
# key = a
|
|
# key = b
|
|
# key2 = c
|
|
params['key'] = ['a', 'b']
|
|
params['key2'] = ['c']
|
|
|
|
To use plain key value mapping, use `multiple_values: false`:
|
|
|
|
# # file structure:
|
|
# key = a
|
|
# key = b
|
|
# key2 = c
|
|
params['key'] = 'b'
|
|
params['key2'] = 'c'
|
|
|
|
### standalone_comments
|
|
|
|
Use `standalone_comments` to parse comments as a line, otherwise inline comments are allowed:
|
|
|
|
'key = value # comment'
|
|
params['key'] = 'value # comment'
|
|
|
|
Use `standalone_comments: false`, to parse the following:
|
|
|
|
'key = value # comment'
|
|
params['key'] = 'value'
|
