Defined in:

Overview

Beware, strange “installer” coming your way.

This push text installer pushes simple configuration into a file.

Example Usage

Installing magic_beans into apache2.conf

package :magic_beans do
  push_text 'magic_beans', '/etc/apache2/apache2.conf'
end

If you user has access to ‘sudo’ and theres a file that requires priveledges, you can pass :sudo => true 

package :magic_beans do
  push_text 'magic_beans', '/etc/apache2/apache2.conf', :sudo => true
end

A special verify step exists for this very installer its known as file_contains, it will test that a file indeed contains a substring that you send it.

package :magic_beans do
  push_text 'magic_beans', '/etc/apache2/apache2.conf'
  verify do
    file_contains '/etc/apache2/apache2.conf', 'magic_beans'
  end
end
