[Puppet Users] trying to resolve group dependency in creating users

Hi all,

Using Puppet 2.5, I have a class which creates users:

# cat modules/users/manifests/init.pp

class users {
  user { ''ringo'':
    ensure     => present,
    uid        => ''1506'',
    groups     => [''admin''],
    shell      => ''/bin/bash'',
    home       => ''/home/ringo'',
    managehome => true,
    password =>
''$6$jomSNhWn$AbuCjrUnLgmq5KfGygIcChHxM9Oxodcgv3ngHpbhJdJ4jzbsWt8Aj8aQI6G3WPqFe.mrG42KbD/'',
  }
}


And one that creates the group:



# cat modules/groups/manifests/init.pp

class groups {
  group { "admin":
    ensure => present,
  }
}


However, the group "admin" needs to be created before the user can be
part of it.

I have tried adding require => Class[''groups''] to the user.
I have
tried using the "before" syntax.  Also tried adding a statement at the
top of the users init.pp, requiring groups.

I can not seem to avoid the error:


err: //users/User[ringo]/ensure: change from absent to present failed:
Could not create user ringo: Execution of ''/usr/sbin/useradd -u 1506
-G admin -d /home/ringo -p
$6$jomSNhWn$AbuCjrUnLgmq5KfGygIcChHxM9OxoNczO7gtHqsngHpbhJdJ4jzbsWt8Aj8aQI6G3WPqFe.mrG42KbD/
-s /bin/bash -m ringo'' returned 6: useradd: group
''admin'' does not
exist

Or some version of a "Found dependency cycles in the following
relationships" type of error.

Any help ensuring that the group dependency is met before users are
created, would be appreciated.

-Jim

Re: [Puppet Users] trying to resolve group dependency in creating users

Have you tried including require => Group[''admin''] in the
user declaration?
I try to perform my Requires at the resource level instead of the class
level if at all possible.

Puppet.  If you''re managing the group ''admin'' and the
user ''ringo'' and ringo
needs to be a part of the ''admin'' group, Puppet will do the
right thing.

Having said that - you want the ''gid'' parameter as that will
set the default
group.  ''groups'' is an array of groups for which ringo is a
member, but gid
is what you want here.  Give that a try and see if it works for you.

[Puppet Users] Re: trying to resolve group dependency in creating users

Hi and thanks for your response.

Yet I was getting errors when creating users.  Puppet was complaining
"Found dependency cycles in the following relationships", and listing
my users as depending on the "admin" group.

OK, this seems like the ticket, but not sure exactly what you mean.

In my "groups" module, should I set the gid explicitly like

class groups {
  group { "admin":
    ensure => present,
    gid => 500,
  }
}

and then in my users class:


class users {
  user { ''ringo'':
    ensure     => present,
    uid        => ''1506'',
    gid     => 500,
    shell      => ''/bin/bash'',
    home       => ''/home/ringo'',
    managehome => true,
    password => ''$6$jomSNhWn
$AbuCjrUnLgmq5KfGygIcChHxM9Oxodcgv3ngHpbhJdJ4jzbsWt8Aj8aQI6G3WPqFe.mrG42KbD/'',
  }
}

?

The problem there is that I can''t be sure whatever gid I choose
won''t
be taken on the client machine.  (I am moving an existing cluster over
to puppet.)

Thanks again
Jim

You can actually do this:

gid  =>  ''admin'',

It will do what you want :)
