Puppet users - Apr 2007 - advice on pseudo iteration needed (mailman recipe)

hello list,

what i want to archive is something like this:

    include mailman

    manage_mailing_list {"chatml":
        password => "asdfasdfasdf",
        subscribers => ["darks@fet.org",
                        "hand@dampf.de",
                        "i.am.cool@yoo.org"
                        ]
    }

which should create the mailinglist and subscribe the given users.
i have attached the corresponding class and defines. this works ok for
one list but unfortunately not for several lists, since puppet barfs on
the object names of the subscribe_to_mailinglist definition, if the same
user belongs to several mailinglist.

i''m banging my head but i don''t find a solution, because of
the missing
iterator object. probably i would be best to introduce a native mailman
type, but unfortunately my ruby knowledge is currently close to none.

any other hints ?

holger

You have indeed met a fundamental limitation in puppet's current data model:
resources have to have a single-valued "primary key". To work around
that you
could use a template, which can contain arbitrary ruby code:

<% subscribers.each |sub| %> <%=sub%> <% end %>

and use that as input for some tool or just maintain the list of subscribers 
in a external file and copy that over with puppet.

What about having the manage_mailing_list definition create the  
mailinglist without the subscribers, and then copy over a list of  
subscribers and subscribe them in an exec statement and have that  
subscribe to the list of subscribers? That way you separate the list  
of subscribers from your puppet manifests, and get the added benefit  
of the automatic update of the subscriberlist.

Hmm, not very well-written, but I hope you get the point...

i tried adding this the wiki myself, but i can''t find out, howto do
this
in the correct way. anyway, all files attached, fell free to add to the
wiki if somebody finds this usefull.

this recipe was made for debian etch, so some paths or package names
might vary on other distributions.

usage:

    include mailman

    manage_mailing_list {"mailman":
        password => "6A0hJxGpUn",
    }

    optional parameters:

    owner => string, define list owner
    moderators => [string,...], define list moderators
    moderated => true/false, define default list policy
    subscribers => [string,...], subscribe users to list
    listdomain => string, define mailinglist domain
    ensure => present/absent, create or remove list
    unsubscribe => [string,...], unsubscribe users from list

this could for sure be optimized, but i works for me like that ;-)

holger
