A module's init.pp, if non-empty, should contain only the definition of a
class (not a definition) sharing the name of the module. That's what you
want in this case anyway:
modules/users/manifests/init.pp:
class users {
$users = flatten(hiera_array('lusers'))
user::user { $users: }
}
modules/users/manifests/user.pp
define user::user () {
user { "$name":
ensure => present,
shell => '/bin/bash',
home => "/home/$name",
managehome => true
}
}
Notes:
1. To collect values for the same key from multiple levels of your data
hierarchy, you need to use either hiera_array() or hiera_hash(). The plain
hiera() function will give you only the value from the highest-priority
level.
2. The flatten() function comes from the "stdlib" add-on module. You would
need it in the example because, with the data as given, hiera_array() will
return an array of arrays, whereas you want a single array whose elements
are the usernames.
3. The only reason you need a defined type is that you want to
explicitly declare the home directory name based on the username. If none
of the properties were derived from the username then you could just use
native User resources directly.
4. All quoting (and non-quoting) in the example is exactly as you should
have it. In several cases, adding quotes or changing the quote type will
change the meaning.
5. You would use the example by via "include 'users'"
