If you have class foo and want to use it inside class bar

Copy code

class bar(
  String $param = 'value',
) 
{
  class { 'foo':
    <foo's params>
  }
}

exxample:

Copy code

class profille::some_stuff(String $reference_to_user_class){
}

class user: {
  user { 'you':
  uid   => 'some_value',
  gid   => 'some_gid',

user

is not a class, it’s a resource type. I’d suggest scouring https://puppet.com/docs/puppet/7/puppet_language.html to see how to use classes and types. Also, https://puppet.com/try-puppet/puppet-learning-vm/ is a bit more Puppet Enterprise-based, but you can get an idea of how some of this stuff works and files are laid out.

Copy code

class profile::some_stuff(
  String $my_user = 'default_username',
)
{
  user { $my_user:
    home => "/${my_user}",
  }
}

Should work. If it doesn’t, there must be something strange going on in some other manifest that’s trying to use this class, perhaps. What you had before seemed right besides the typo, so there must be other manifests in play here. There should be no other

user

resources with the same title (in the example above, whatever the value of

$my_user

is), including using

ensure_resource

with that name (unless you provide the exact parameters declared in the other place you are using that resource, but I would probably just avoid using ensure_resource unless you really need it).

btw here this is the class that I created main class:

Copy code

class some::other::class( has $user){
...
# Creates the resource if it does not exist, update if needed otherwise do nothing
ensure_resources(profile::some_user, $user)
}

Define after second class above

Copy code

class profile::some_user(
String $my_variable= 'some_string'
)
{
  user { $my_variable:
    ensure     => present,
    forcelocal => true,
    gid        => 'some_gid',
    groups     => 'some_group',
    home       => "/${my_variable}",
    managehome => true,
    notify     => Selinux::Exec_restorecon["/${my_variable}"],
    uid        => 'some_uid',
  }
}

Instead of the top one, do:

Copy code

class some::other::class(
  String $user,
) {
  class { 'profile::some_user':
    my_variable => $user,
  }
}

Then in site.pp (or some other place you are applying classes to a node):

Copy code

node mynode {
  class { 'some::other::class':
    user => 'the_user_i_want_to_create',
  }
}

Looks like

ensure_resource('class', 'profile::some_user', { my_variable => $user })

would probably work in your main class
