[Puppet Users] Override configuration defined in inherited node?
Hi all. I'm running puppet 0.24.4, and have the following issue: I have a base node which more or less every linux server inherits. In the base node I've defined a default NTP client configuration, but now I've come across a couple of nodes that need a different configuration. So what I need to do on these particular nodes are, as far as I know, one of these things: 1) Find a way to override the NTP configuration defined in the base node 2) Make sure they don't inherit the base node, so that I can define a different NTP configuration here So is there a way to override a configration defined in the base node (i.e. the inherited node)?

[Puppet Users] Issues with clients connecting
Hello,
I am working on moving to a new puppetmaster. Along with this move I
am updating to Puppet 0.24.8.
As it stands, my test client can't connect:
notice: Starting Puppet client version 0.24.8
debug: Loaded state in 0.00 seconds
debug: Retrieved facts in 1.12 seconds
debug: Retrieving catalog
debug: Calling puppetmaster.getconfig
err: Could not retrieve catalog: Could not find node
'vz200b.liquidweb.com'; cannot compile
On my puppetmaster we are using an external_nodes.py script:
### Imports
import sys
import re
import time
import yaml
### Constants
# puppet user must have read acces to this
NODEFILE = '/etc/puppet/nodes.yaml'
# puppet user must have write access to this
LOGFILE = '/var/log/puppet/nodes.log'
### Arguments
hostname = sys.argv[1]
### Functions
# Open NODESFILE and load the two documents into structures, return as
tuple
def parse_nodefile():
f = file(NODEFILE, 'r')
docs = yaml.load_all(f.read())
f.close()
return (docs.next(), docs.next())
# Write a msg to LOGFILE
def log(msg):
f = file(LOGFILE, 'a')
timestamp = time.strftime('%Y%m%d-%H:%M')
f.write(timestamp + ' - ' + msg + '\n')
f.close()
### Action!
(regexes, modules) = parse_nodefile()
for nodetype, regexlist in regexes.iteritems():
for regex in regexlist:
p = re.compile(regex)
m = p.match(hostname)
if m:
found_nodetype = nodetype
modulelist = modules['default']
try:
if found_nodetype and modules[found_nodetype] is not None:
modulelist.extend(modules[found_nodetype])
except NameError:
log(hostname + ' doesn\'t match a defined node type')
sys.exit(1)
yamldoc = {'classes': modulelist}
print yaml.dump(yamldoc, explicit_start=True,
default_flow_style=False)
# Puppet expects a return code of 0 to signal to indicate success
# and non-zero for error or a non-regcognized hostname
sys.exit(0)
Which does work how I would expect:
[r...@vpsadmins ~]# python /etc/puppet/tools/external_nodes.py
vz200b.liquidweb.com

[Puppet Users] Re: Server Hierarchies Part Two (Puppet's Revenge)
In James Turnbull's book there's a good discussion on the variable
scoping issue (excellent book btw, a must have). He offered a
workaround by defining the variable you want to override outside the
class scopes. So you could try
$ntp_servers = ['ntp01.example.com',
'ntp02.example.com']
class zones::global {
$ntp_acls = ['']
include ntp
}
class zones::nyc {
$ntp_servers = ['ntp01.othersite.com',
'ntp02.othersite.com']
include zones::global
}
node host1.example.com {
include zones::nylrc
}

Wow, how did I miss that? That may very well solve a bunch of my
problems- it's not as transparent as I would prefer (you can't see at
a glance what resources a node references) but it has got to be better
than what I'm dealing with now. Thanks for the feedback.
Nope spoke too soon. Scoping screws this up.
For example:
class zones::global {
$ntp_servers = ['ntp01.example.com',
'ntp02.example.com']
$ntp_acls = ['']
include ntp
}
class zones::nyc {
$ntp_servers = ['ntp01.othersite.com',
'ntp02.othersite.com']
include zones::global
}
node host1.example.com {
include zones::nylrc
}
The variables in global are available to NYC but the variables I have
overridden in NYC are not available to global. In the end,
host1.example.com ends up with ntp01.example.com as it's NTP server
instead of ntp01.othersite.com because of scoping.
Am I crazy for thinking this sort of hierarchical structure would be
amazingly useful and is basically impossible with puppet?
Is there some reason I am missing that would make the above a terrible
idea?
Without the above sort of hierarchy I'm going to end up with a jumble
of logic statements and node descriptions that could otherwise be made
incredibly simple.
What am I missing?

In James Turnbull's book there's a good discussion on the variable
scoping issue (excellent book btw, a must have). He offered a
I have it, and while a good book, I don't think my problems are with
understanding the issues- I just want puppet to do things it can't.
$ntp_servers = ['ntp01.example.com',
'ntp02.example.com']
class zones::global {
$ntp_acls = ['']
include ntp
}
See- now you're defining a role (ntp) and settings ($ntp_acls) for
that role all in the same place. I wanted to use zones to define
various settings and then just keep overriding them. If I include
classes then the scoping rules prevent the variables in my zone class
from being seen by my role class so that doesn't work either.
What I've started doing is to use inheritance to build a variable
tree:
node global {
ntp_servers = ['']
}
node zonenyc inherits global {
$ntp_servers = ['10..1.1.10']
}
node client inherits zonenyc {
include roles::general
}
node ntpmaster inherits zonenyc {
$ntp_servers = ['pool.ntp.org']
include roles::general
include roles::ntpmaster
}
It's not nearly as clean as I would like, but at least I can override
variables and accomplish most of what I want to do.

[Puppet Users] Puppet + HAProxy
Hello, The Puppet footprint within my company is steadily growing, We took the basic steps to make it more robust (passenger + apache) but in order to meet the needs of a 24x7 shop I need redundancy. I've read the Reductive Labs WIKI about redundancy (http://reductivelabs.com/ trac/puppet/wiki/Recipes/HighAvailability) but I was wondering if anyone has experiences (good or bad) using HAProxy to achieve HA on the puppetmaster side.

[Puppet Users] Re: Override configuration defined in inherited node?
couple of nodes that need a different configuration. So what I need to do on
these particular nodes are, as far as I know, one of these things:
1) Find a way to override the NTP configuration defined in the base node
2) Make sure they don't inherit the base node, so that I can define a
different NTP configuration here
I literally just asked this same question and the solution is less
than stellar.
Node inheritance is useful for variables and overriding. Classes are
useful for specifying system roles.
In more concrete terms this is what I do:
class roles::general {
include ntp
include ldap
}
class roles::ntpserver {
include ntp::master
}
node zone-global {
ntp_servers = ['']
}
node zone-nyc inherits zone-global {
$ntp_servers = ['10..1.1.10']
}
node client inherits zone-nyc {
include roles::general
}
node ntpmaster inherits zonenyc {
$ntp_servers = ['pool.ntp.org']
include roles::general
include roles::ntpmaster
}
This isn't nearly as clean as it could be if some of the variable and
scoping rules were different, but for now it has sufficed to clean up
my puppet config dramatically.

[Puppet Users] Performance of Passenger vs. Mongrel
Howdy: How does Passenger perform compared to Mongrel? For us Passenger looks worse. We have two puppetmasters; one does file serving, the other does everything else. We just started running 0.25 beta2 on both. The file-server is running RubyEE + Passenger and the non-file-server is running Mongrel. When our heavy-hitter schedule runs the load average on our file server spikes much higher than it did when it was running 0.25 beta1 with Mongrel. We will try 0.25 beta2 + Mongrel on our file server to see if that makes a difference but I'm curious what others have seen and what we should expect.

include admin
}
groups/admin.pp:
class admin {
include example
}
modules/examples/manifests/init.pp:
class example {
if $webserver{
$webserver = true
} else {
$webserver = false
}
file { example_file:
path = /tmp/example.file,
owner = root,
group = root,
mode = 644,
content = template(example.erb),
}
}
templates/example.erb:
All machines get this text.
% if webserver == true -%
Then insert this text, too.
% end -%
Things to note: due to scoping rules, your node must *include*, not
inherit, the class that contains the module that has the template in it.
I.e., in my example, if admin01 inherited the dev class, this does not
work. Presumably, somebody, I'll understand the scoping rules enough to
know why that is. Today... is not that day.
Also, the $webserver variable *must* be set before includeing the
class that contains the template. Otherwise, see previous paragraph.
And yes, you could set the $webserver variable to whatever you wish, but
setting it to role helps keep things clear in my configs. And no, I
don't understand why the example class can see that the $webserver
variable exists, but the template can't unless I re-set it. See
two-paragraphs up.
Finally, you can set $webserver at the group (class) level, in - say -
groups/admin.pp, as long as you follow the set the variable first
rule. In this case, you would remove that line from the node
definition, and change admin.pp to the following:
class admin {
$webserver = role
include example
}
Hope that helps somebody else.

P.S. Keyword dump, to help searchers in the future hit this post:
tagging, special case, inheritance, override configuration,
hierarchies, how do I make this stupid thing work?

I know I'm missing something very basic, but I've been beating my head
on this for hours now without making progress. I'm trying to 'tag'
nodes with various values, to be pulled later in some home-grown
modules. For instance, I want to mark machines as being a webserver,
and then in my yum repo module, I have a template that checks for
webservers and adds a custom repo if true. I'm very flexible in the
details - I don't care if it's a custom variable, a tag, a fact,
whatever. The only thing I *don't* want to do is use inheritance and
groups to do this - any given machine will be tagged with various
different things, and trying to maintain groups would quickly become
unmanageable. And unfortunately, this isn't something that can be
discovered automatically using facter, at least as far as I can tell.
An example of a failed attempt would be (all files stripped down, but
the meat is there):
nodes.pp:
import modules
import groups/*
import roles/*
node 'admin01.dev.example.com' inherits admin { include webserver }
roles/webserver.pp:
class webserver {
$webserver = true
}
templates/repo.erb:
The value of the variable is %= $webserver::webserver %.
I also tried $::webserver (after moving it out of the class definition),
$webserver, setting a tag in the class and then reading out the defined
tags, and more. But that should give you guys an idea of what I'm
aiming to do.
Thanks for any pointers!

[Puppet Users] Ensure overriden service after exec has run
Hi,
How do I force my Service declaration (with is defined elsewhere and
inherited) is run after an exec has run?
The code;
class autofs_nis::services inherits services::base {
Service['ypbind'] {
ensure = running,
enable= true,
}
.
}
class autofs_nis::exec inherits services::base {
exec { setdomainname:
command = domainname blanked,
path = /bin,
unless = [[ $(domainname) == \blanked\ ]],
}
}
Open to suggestions to do this differently.

[Puppet Users] Re: Installing applications using puppet
Hi,
I am new to puppet as well, but I could tell you how to do a similar
install.
exec { getthesource:
command = wget http://thesourceurl;,
cwd = /the/directory/to/issue/this/command/from
}
exec { untarthesource:
command = the_untar_command,
cwd = the/directory/to/issue/this/command/from,
require = Exec[getthesource]
}
exec { ./configure:
command = the/directory/to/issue/this/command/from/configure,
cwd = as above,
require = Exec[untarthesource]
}
And the other steps follow in a similar manner.. You should probably check
the exec resource type in the type reference.
.
But, I think this is not the most elegant way of doing it... There is the
package resource type in puppet which can be used to install packages from
binaries, but yes, I haven't found another way to install from source.

Are you sure you're not doing something weird with your Ruby install?
On Leopard, do you have the default symlinks still?
/usr/lib/ruby -
../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/ruby
/usr/lib/ruby/site_ruby -
../../../../../../../../../../Library/Ruby/Site
There are packages out there that incorrectly fail to follow symlinks
for these directories, and break Ruby in lots of ways under Leopard.
Older bundled packages of RubyCocoa are a prime culprit.
