Hi @all,
I write a module that create local users on my boxes. Now I try to make
that module fully dynamic so that the user informations are passed to
the module as parameter like this:
class { 'local_users':
user => [
{ 'john' => { name => 'John Doe', home => '/export/home/john' } },
{ 'jane' => { name => 'Jane Doe', home => '/export/home/jane' } }
]
}
You could use a hash there directly instead of an array of hashes. The
'id' (e.g. 'john', 'jane' has to be unique anyway.
So far, so good. But now I would like to iterate through the user array
and create the user resource and I have no clue how this should be done
correctly. My approach is to call a define:
local_users::config::account { $local_users::user }
Which look like this:
define local_users::config::account (
$id = $title,
$name = undef,
$home = undef
) {
user { $id:
ensure => present,
comment => $name,
home => $home,
managehome => true,
password => '!!';
}
}
I guess the direction should be understandable, I would like to specify
the users and their attributes as a parameter. What I don't get so far
is, do I need one resource definition for each possible combination or
is there a way that only the parameter that contain values are used
within the resource type? Is the path in general the correct one that I
use or is there a better approach to get this done?
If you are on 3.x with future parser, or on 4.x you can iterate.
I made some simplifications here, everything is one hash, and
I renamed 'name' to 'comment' so I could use the hash directly
to set all attributes without having to first transform 'name'
into 'comment'.
class { 'local_users':
user => {
'john' => { comment => 'John Doe', home => '/export/home/john' },
'jane' => { comment => 'Jane Doe', home => '/export/home/jane' }
}
}
class local_users($users) {
$users.each |$id, $attributes | {
user { $id:
managehome => true,
password => '!!',
* => $attributes # attributes from hash
}
}
}
With typed parameter
----
To make it more robust you can also type the $users argument
class local_users(
Hash[String, Struct[{
name => String,
home => String}]
] $users)
{
$users.each |$id, $attributes | {
user { $id:
managehome => true,
password => '!!',
* => $attributes
}
}
}
Hope that helps.
