Puppet users - Jun 2012 - Puppet Configuration - Running --configprint generates long list of values

Hello all,

I fairly new to puppet and google groups so I''ll apologize in advance
for
not conforming to "normal" posting methods.

I''ve recently installed puppetmaster on a fresh copy of Ubuntu 10.04LTS
and
after running: sudo puppet --configprint all, I get a long list of 
parameters and values echoed back to my shell.  My question is where do 
these parameters and values come from?  I''ve taken a look at my
puppet.conf
file (which I believe is located in the proper place of: 
/etc/puppet/puppet.conf) and it looks like this:

[main]
logdir=/var/log/puppet
vardir=/var/lib/puppet
ssldir=/var/lib/puppet/ssl
rundir=/var/run/puppet
factpath=$vardir/lib/facter
templatedir=$confdir/templates

[master]
# These are needed when the puppetmaster is run by passenger
# and can safely be removed if webrick is used.
ssl_client_header = SSL_CLIENT_S_DN 
ssl_client_verify_header = SSL_CLIENT_VERIFY

Clearly these values of the ''''--configprint -all" command
are coming from
somewhere else and I can''t seem to find the answer.  

I''ve read that puppet will read values from a users home directory if
the
puppet service is not running as root but I''m not sure that''s
something I
should be concerned with at the moment.

My thanks to everybody''s help in advance.

Cheers,

Mike

----
--configprint will supplement anything not specifically configured in
puppet.conf with its own defaults. Thus you can ''override'' any
of the defaults by specifically declaring them in the appropriate section of
puppet.conf

Defaults! Even if you only SET a few settings in puppet.conf, all of the 
POSSIBLE settings still have values. These default values are set in a file 
called defaults.rb, which is part of Puppet''s code. See it here: 
https://github.com/puppetlabs/puppet/blob/master/lib/puppet/defaults.rb Or 
you can see the config reference at 
http://docs.puppetlabs.com/references/latest/configuration.html --- that 
explains most of the default values. 

You''ll notice that many settings are set *in terms of* other settings,
so
that you end up only really having to set a small core group of settings. 

What is that small core group? Well... that''s kind of tricky to tease
out,
actually. The historical context is that we''ve tended to make every
global
constant in Puppet''s code into a configurable setting, and the result
is
that we have over 200 of them. We know that''s a problem; a lot of the
work
we''re doing these days can be summarized as "reduce configuration,
make
things more knowable." But once you add a configurable knob, someone might 
start using it, and removing it becomes a lot harder than not having put it 
in would have been. 

But the list of the most important settings here 
(http://docs.puppetlabs.com/guides/configuring.html#puppets-settings) is a 
good place to start. You won''t need to know much more than that for a 
while.

Thank you for the reply Craig.  That makes sense and points me in the right 
direction.

Thanks again,

Mike

Hey Nick,

Thank you for the reply.  I''ll take a look at the defaults.rb file and
see
what I can make of it.  The explanation regarding the "core group"
settings
is most helpful and makes perfect sense.  

Again, thanks for the informative links and the info.

Cheers,

Mike
