cpan resource

[edit on GitHub]

Use the cpan Chef InSpec audit resource to test Perl modules that are installed by system packages or the CPAN installer.

Availability

Installation

This resource is distributed with Chef InSpec and is automatically available for use.

Version

This resource first became available in v1.43.5 of InSpec.

Syntax

A cpan resource block declares a package and (optionally) a package version:

describe cpan('package_name') do
  it { should be_installed }
end

where

• 'package_name' is the name of the package, such as 'DBD::Pg'
• be_installed tests to see if the package described above is installed

Resource Parameters

This resource uses package names and perl library paths as resource parameters.

Resource Parameter Examples

Test if DBD::Pg is installed on the system

describe cpan('DBD:Pg') do
  it { should be_installed }
end

Test if DBD::Pg 3.7.0 is installed on the system

describe cpan('DBD::Pg') do
  it { should be_installed }
  its('version') { should eq '3.7.0' }
end

Test if DBD::Pg is installed within a custom PERL5LIB path on the system

Hint: You can pass multiple paths separated with a colon /path/to/perl5/lib:/usr/share/perl5/vendor_perl/lib/perl5

describe cpan('DBD::Pg', '/home/username/perl5/lib/perl5') do
  it { should be_installed }
end
