$location = "Mountain View"
$country = "US"
$state = "CA"
$organization = "Google"
$unit = "Search"
$commonname = "www.example.com"
$keyname = "www_example_com"

$subject = "/C=${country}/ST=${state}/L=${location}/O=${organization}/OU=${unit}/CN=${commonname}"
$createcertificate = "openssl req -new -newkey rsa:2048 -x509 -days 365 -nodes -out ${keyname}.crt -keyout ${keyname}.key -subj \"${subject}\""

exec { "openssl-csr":
  command => $createcertificate,
  cwd => '/home/vagrant',
  creates => "/home/vagrant/${keyname}.key"
}
