Puppet users - Mar 2012 - Dashboard, node classes, what do they do part 2

Hi folks,

Went back and did some more reading and found the intriguing entry in the
Dashboard documentation

"The classes the console knows about are a subset of the classes in your
puppet master’s collection of modules. You must add classes to the console
manually if you want to assign them to any nodes or groups."

OK fair enough.  I have a class (just picking one) defined in a module
called postfix::inbound which I defined on the console and added it to a
host group of which a brand new clean server.  For now the class is written
just to notify that it is being invoked.

When I run the puppet agent I don''t see the class being applied.

Am I hoping for too much?

Maybe :)

In the Dashboard, when they say "classes" they really mean
"module".
Add "postfix::inbound" instead of the actual class inside of the
module to the Dashboard and it should work just fine for you.

This begs a follow-on question:

if classes == modules in Dashboard then maybe I need to take a second look
here.

The module that I am writing from scratch to work with Dashboard is called
postfix.   If I understand what you are saying and what the documentation
infers I need to re-architect my module a bit.

This module is supposed to handle four distinct postfix cases:

   1. null client
   2. post office box (handles IMAP/POP accounts, receives email but sends
   through a relay)
   3. inbound only
   4. outbound only


Given that I guess I should be setting a parameter within Dashboard
(I''ll
call it postfix_mode) and set up within the postfix class inside of init.pp
file within the postfix module such that:

case $:postfix_mode {
    "null client" : { include postfix::nullclient }
    "inbound"   : { include postfix::inbound}
    ---- etc ----
}

Am I on the right track?

Actually, after I sent this I started thinking about it a bit more.
I''m just getting started with Dashboard and it''s been working
for me
to just put in the "module" name in the Dashboard and not the
class-name. But I''m not sure if this is because my "class"
name up
till now has always been same as the module name and it has up till
now always resided inside of the init.pp in the module. So, I guess
what I''m saying is that I''m not so sure if classes == modules
in
Dashboard. It may be that if you have other classes in the module you
may be able to call them directly with "modulename::classname" (?) but
I''m not really sure. I''d just test it out for a while to
figure it
out.

I actually have figured this out (with some help from the list.)  Seems I
was encountering a PEBKAC error. :-)

I hadn''t set up puppet to use dashboard for external node
classification.
(so that''s what it''s useful for! hmmm...)
