Variables declation

Hello guys,

I need help about variables declaration. I use puppet apache module to
install httpd, php, vhost and I want to put variables to configure my
vhosts with foreman but I have no idea how to declare my variable

For example to configure directories in my vhost, in the module I need to
do that

directories => [
{ path => '/var/www/drupal', allow_override => 'All', allow => 'from All'
},
{ path => '/var/www/symfony/web', allow_override => 'All', allow => 'from
All', options => ['Indexes', 'FollowSymLinks','MultiViews'] }
]

But I have no idea how to interpret that in foreman

Thanks for you help
