deferred_epp.pp

# A quick and untested implementation of a deferred_epp() function to abstract
# the fiddly bits for deferring a template and render it agent side.
#
# Note: This depends on my find_template() PR.
#
# Note: If you're resolving variables agent side, then you'll have to defer
#       them as well. Pass them in via the $variables hash like this example:
#
#       $variables = {
#         'password' => Deferred('vault_lookup::lookup',
#                         ["secret/test", 'https://vault.docker:8200']),
#       }
#       file { '/etc/secrets.conf':
#         ensure  => file,
#         content => deferred_epp('mymod/secret.conf.epp', $variables),
#       }
#
function stdlib::deferred_epp(String $path, Hash $variables) >> Deferred {
  Deferred('inline_epp',
    [find_template($path).file, $variables]),
}
