[Puppet Users] Puppet defined types and defaults parameters

Hi,

You shouldn't be trying with a variable. Here's what you should
probably be doing instead :

/etc/puppet/modules/sensor/manifests/listner.pp
define sensor::listner ( $config = 'this is the generic default' ) {
notify { $config : }
}

/etc/puppet/manifests/site.pp
Sensor::Listener { config => 'asdf' }
node 'dev' {
sensor::listner {"test_sensor":}
}

This would show 'asdf' for all of your nodes, since the default would
be set inside site.pp, thus inherited globally.

I'm not sure it's fair to say that. I am a bit surprised that the OP's
code doesn't work, in fact. Now, I don't think it's a good idea to do it
that way, but I suppose it's a model for some more complicated thing that
the OP is planning.

Some things that might make the example work, either individually or
jointly, are

- move the variable declaration to site.pp
- change the parameter declaration to $config = $::myvar


That's a good solution where it applies, but it does have the limitation
that it's extrinsic instead of intrinsic.

If the default needs to be associated with the definition's module, then a
different approach is needed. Before I suggest other alternatives,
however, I'd like to know more about the objective. Why does the default
need to come from a variable? Who is responsible for assigning the
variable's value (site admin / module dev / computed by Puppet / ...)? To
what does / should the variable belong (overall site / module / some
specific class / ...)?
