Puppet Function: stdlib::deferrable_epp

Defined in:
vendor_modules/stdlib/functions/deferrable_epp.pp
Function type:
Puppet Language

Overview

stdlib::deferrable_epp(String $template, Hash $variables) ⇒ Variant[String, Deferred]

This function returns either a rendered template or a deferred function to render at runtime. If any of the values in the variables hash are deferred, then the template will be deferred.

Note: this function requires all parameters to be explicitly passed in. It cannot expect to use facts, class variables, and other variables in scope. This is because when deferred, we have to explicitly pass the entire scope to the client.

Parameters:

  • template (String)
  • variables (Hash)

Returns:
