Hi Stephen,
As per my understanding of your query, you want version parameter value
5.5 as default and on passing parameter value its become 5.3.
But in your case its take version = 5.5. Correct me if i am wrong.
Solution for your query is u have to construct parameterized class maria
and it has to be inheriated by maria::params.
# maria class
class maria (
$version = maria::params::version
) inherits maria::params {
notify { "$version" :}
}
# params class
class maria::params {
$version = '5.5'
}
# when we call the class maria with version parameter it set the $version
value to passed value (here 5.3)
class {"maria":
$version => '5.3'
}
# when we call the class maria without version parameter it set the
$version value to default value from params class (here 5.5)
class {"maria":
}
I hope this will solve your problem. If i interpreted your query correctly.
Thanks and Regards,
Rahul Khengare.
