A custom fact that uses regex to grab the fourth, dash-separated value from the
hostname seems like a good way to go as it would make the $env value accessible
globally.
Alternatively, you can use a selector within your manifests:
$env = $hostname ? {
/-dev-/ => 'dev',
/-int-/ => 'int',
/-qa-/ => 'qa',
/-prod-/ => 'prod',
}
