So I can't use a hash? I'm trying to make a general use parameterized
class using a profile . . . Can I do something like this so I only have to
pass in the service name that I want to configure from my node definition:
class profiles::dropwizard (
$dw_service = 'dw_service_UNDEFINED',
$amqp_host = hiera($dw_service::amqp_host)
)
than my role would be:
class roles::showroom inherits roles::base {
class { profiles::dropwizard:
dw_service => 'showroom',
}
}
Hiera isn't able to find the above, and i've tried with varying curly
braces. Sorry if this is getting convoluted & out of scope.
