As far as i know there's no other puppet-dsl-like way to get parameter of
defined resource, so that's why i implemented getparam function, which takes
resource reference and parameter name and returns parameter value.
Here's another example why this function is really useful:
define config($path, $config_param1, $config_param2) { }
define example_resource($config) {
$path = getparam($config, "path")
notice("Path is $path")
}
define example_resource2($example_resource, $config = getparam($example_resource, "config")) {
$config_param1 = getparam($config, "config_param1")
notice("Config parameter is $config_param1")
}
define example_resource3($example_resource, $config = getparam($example_resource, "config")) {
$config_param2 = getparam($config, "config_param2")
notice("Config parameter is $config_param2")
}
class test_getparam {
config { "config_instance":
path => "/some/config/path",
config_param1 => "someconfigtext1",
config_param2 => "someconfigtext2",
}
example_resource { "example_resource_instance":
config => Config["config_instance"]
}
example_resource2 { "example_resource_instance":
example_resource => Example_resource["example_resource_instance"]
}
example_resource3 { "example_resource_instance":
example_resource => Example_resource2["example_resource_instance"]
}
}
class { "test_getparam": }
