You dont have to specify it on every node. Thats what a default value
is for.
Take this as an example:
define your_definition($role=default) {
file { "/path/to/your/file":
ensure => present,
content => template("your_template")
}
}
Now, if you call it with
your_definition { "resource_name": }
$role will have the value "default" in your template
if you call it with
your_definition { "resource_name":
role => "fast",
}
your $role will have the value fast
Not what you want, since you would have to flick a switch on your node
definition, but I tend to deal these issues like this:
class yourmodulename {
$role = "default"
your_definition { "resource_name":
role => "$role",
}
}
define yourmodulename::your_definition($role=default) {
file { "/path/to/file/to/controll":
ensure => present,
content => template("yourmodulename/templatename")
}
}
Then you can subclass this and override the $role=default
So the subclass in the module would look like:
class yourmodulename::yoursubclass inherits yourmodulename {
$role = "fast"
Your_definition['resource_name'] { role => "$role" }
}
In that case every place you include the subclass the template is fed
with "fast" as the value for $role. Im sure you can find other ways to
deal with it all well.
