Greetings,
I could use some clarity on node scope, class scope, and best practices. I
have the following:
# Node definition
if $hostname == 'mynode-dev' {
$app_version = '1.0'
include robin_dev
}
# Class definition
class robin_dev {
if $app_version == undef {
$app_version = '0.5'
}
include robin_dev::install
}
class robin_dev::install {
package {
"app_name": ensure => $robin_dev::app_version;
}
}
My intent is to set $app_version within my node definition. If
$app_version is not set there, I 'd like it to default to a version that is
set within class robin_dev itself, which is 0.5 in the above example.
While the above example works as I just described, i'm not understanding
how $robin_dev::app_version referenced in class robin_dev::install returns
"1.0" when I its assigned in the node definition. I initially assumed that
class robin_dev would need to re-assign the variable within the class
itself like this:
# Class definition
class robin_dev {
if $app_version == undef {
$version = '0.5'
} else {
$version = $app_version
include robin_dev::install
}
class robin_dev::install {
package {
"app_name": ensure => $robin_dev::version;
}
}
Any insights would be appreciated. Thank you.
