etc_group resource

[edit on GitHub]

Use the etc_group Chef InSpec audit resource to test groups that are defined on Linux and Unix platforms. The /etc/group file stores details about each group: group name, password, group identifier, along with a comma-separated list of users that belong to the group.

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 etc_group resource block declares a collection of properties to be tested:

describe etc_group('path') do
  its('property') { should eq 'some_value' }
end

or:

describe etc_group.where(item: 'value', item: 'value') do
  its('gids') { should_not contain_duplicates }
  its('groups') { should include 'user_name' }
  its('users') { should include 'user_name' }
end

where

• ('path') is the non-default path to the \etc\group file
• .where() filters for a specific item and value, to which the parameter are compared
• .where filter may be one or more of:
  • name: 'name', group_name: 'group_name', password: 'password', gid: 'gid', group_id: 'gid', users: 'user_name', members: 'member_name'

Properties

gids

The gids property returns the list of gids from /etc/group file.

its('gids') { should include 'gid' }

groups

The groups property returns the list of groups from /etc/group file.

its('groups') { should include 'my_group' }

users

The users property returns the list of users from /etc/group file.
