Yes, I understand that. We don't put our variables in the manifests. We put
them into csv files and use extlookup, which works great. However, I'm not
talking about the use of variables here. I'm talking about logic based on
operating system.
I'd also like to see something, maybe in the best practices document on the
Puppet Labs website indicating which is the correct way to handle specific
operating ystem logic. Having multiple classes (ie a lot of classes) per
module, means more files, which in my opinion, makes things confusing and
it's never really clear which is the best way to break things up. When you
have more than a few files, there's also a tendency to create subdirectories
under manifests/, and have stuff like module::A::B.pp and when you start
doing that, it becomes even more unclear how things should be arranged.
I've been working with puppet for over three years now and variable scoping
still isn't clear to me.

I ended up shutting down puppet for the weekend so that I could deal with it on Monday. Well when I brought up the server on Monday it hasn't had high CPU usage since. It is 5 days later and my loadaverage hovers at around 1-2 as before.

[Puppet Users] Module variables missing during some puppet runs
I am getting the following error on about every other manual run of
puppet... (hostnames removed)
err: Could not retrieve catalog from remote server: Error 400 on
SERVER: Failed to parse template zabbix/userparameter_mysql_conf.erb:
Could not find value for 'zabbix_mysql_user_parameters' at /etc/puppet/
modules/zabbix/manifests/classes/mysql.pp:7 on node
puppetclient.domain
If I then do another puppet run, I do not receive the error. It seems
that just about every other manual run during testing of new module
changes has this happen. This is occuring on ALL my puppet clients
that are using the zabbix::mysql module. All systems running
Puppet-2.6.8. Below is the full debug log and my zabbix module.
The $zabbix_mysql_user_parameters variable is optional...right now
only one node has it defined explicitly, like so:
$zabbix_mysql_user_parameters = {
item1 = { 'name' = 'mediawiki.usercount[*]', 'command' =
'mysql -B -s -e SELECT count(*) FROM user $1'},
}
This is the mysql class for zabbix where the empty variable is defined
so that if no node has it defined it shouldn't fail...
$zabbix_mysql_user_parameters = []
class zabbix::mysql inherits zabbix::agent {
file {
$zabbix_userparameter_config_dir/userparameter_mysql.conf:
content = template(zabbix/
userparameter_mysql_conf.erb),
group = zabbix,
owner = zabbix,
mode= 600,
require = Package[zabbix-agent];
$zabbix_user_home_dir/.my.cnf:
source = puppet:///modules/zabbix/.my.cnf,
group = zabbix,
owner = zabbix,
mode= 600,
require = [ Package[zabbix-agent],
File[$zabbix_user_home_dir] ];
}
}
Here's the variables usage in the template...
% zabbix_mysql_user_parameters.each do |key, value_hash| -%
UserParameter=%= value_hash['name'] %,HOME=%= zabbix_user_home_dir
% %= value_hash['command'] %
% end -%
Would the solution be to make the template call use this instead??
% if has_variable?(zabbix_mysql_user_parameters) -%
% zabbix_mysql_user_parameters.each do |key, value_hash| -%
UserParameter=%= value_hash['name'] %,HOME=%= zabbix_user_home_dir
% %= value_hash['command'] %
% end -%
% end -%

I guess it's up to the site and the Puppet admins on how to break up
their classes. I'm not sure there's an all encompassing best practice as
everyone's requirements will be different. For example if I was just
managing CentOS and Red Hat systems, I might simply embed if/else logic
in a single class and handle the differences in the OS there, as they
are mostly the same and splitting off a separate class might be a waste
of time.
If I was managing a site with Fedora, Ubuntu, Macs, etc, I'd definitely
go down the conditionally include classes and subclasses, mainly for
management reasons, like a typo in class somefile::ubuntu doesn't
affect class somefile::redhat. Also the logging of resources indicates
exactly which class::subclass::subsubclass a resource is declared in, so
I know where to go hunting to make a change to it. In practice I'd make
judgement calls about when to split a class into subclasses based on
operating systems or to nest if/else statements in a class based on how
complex the class was getting, and so I'd have a mixture of both.

file {
$operatingsystem ? {
'centos' = {

Regarding your example above, that won't work, a Selector is a RHS
operator, so can't be used like that. You'd need to either use a case
statement or if/else block, from the docs:
| if $is_virtual {
service {'ntpd':
ensure = stopped,
enable = false,
}
}
else {
service { 'ntpd':
name= 'ntpd',
ensure = running,
enable = true,
hasrestart = true,
require = Package['ntp'],
}
}

[Puppet Users] Re: Server side filebucket issue
Wow I can't believe that's all that was keeping me from having my
filebucket work in the same manner described by LawrleC.
The primary reason I want to use filebucket is to view changes in
Puppet-dashboard. Now that my filebucket works I only have 1/2 the
files viewable in puppet-dashboard.
In dashboard the original shows up when I click the MD5 sum, however
the new version gives me We're sorry, but something went wrong.
We've been notified about this issue and we'll take a look at it
shortly. which I'm guessing is because the file doesn't exist. I
looked in the actual filebucket, and only the original exists. Is
there a way to enable Puppet-dashboard or Puppet to also show the new
version of a file?

It fails because the yum repository by default is requiring the package be signed.

RE: [Puppet Users] Re: Resources existing in different operating systems.
What if the file doesn't exist at all on the other distro? I know for example that centos creates a symlink from /boot/grub/grub.conf to /etc/grub.conf. What if I only wanted to manage this file for CentOS, and for other distro's, do nothing ? Put the file resource inside the case statement itself? -- Russell Howe rh...@moonfruit.com -- You received this message because you are subscribed to the Google Groups Puppet Users group.

[Puppet Users] require? before? I need to have a dependency in place . . .
Hi, I need to have a network interface set up with puppet before I can use the interface (as a facter fact) in a subsequent class which uses the IP of the interface in a template . . . So I really need the interface class to execute on the client, the client to resend its facts, then for puppet to continue on. I've tried using require Class['interface'] in the webserver class and i've tried using before Class['webserver] in the interface class . . . Anyone have any thoughts/suggestions? Thanks a lot, Guy P.S. - does anyone -- You received this message because you are subscribed to the Google Groups Puppet Users group.

Great to see this discussed, thanks for bringing it up.

Having multiple classes (ie a lot of classes) per module, means more files, which in my opinion, makes things confusing and it's never really clear which is the best way to break things up. When you have more than a few files, there's also a tendency to create subdirectories under manifests/, and have stuff like module::A::B.pp and when you start doing that, it becomes even more unclear how things should be arranged. I tend to use a single init.pp still for a lot of things, as I find myself writing a fair amount of common code even across different platforms. I don't find it particularly useful to split it into a new file for common bits, another for Red Hat and another for Solaris. It becomes difficult to manage as dependencies are spread across files and opportunities to rationalise common code are missed. Where I have modules where the OSes have nothing in common then I would split them out into separate redhat.pp and solaris.pp manifests. For me, this is a very small number, but it'll naturally depend on your environment. I guess it's up to the site and the Puppet admins on how to break up their classes. I'm not sure there's an all encompassing best practice as everyone's requirements will be different. For example if I was just managing CentOS and Red Hat systems, I might simply embed if/else logic in a single class and handle the differences in the OS there, as they are mostly the same and splitting off a separate class might be a waste of time. If I was managing a site with Fedora, Ubuntu, Macs, etc, I'd definitely go down the conditionally include classes and subclasses, mainly for management reasons, like a typo in class somefile::ubuntu doesn't affect class somefile::redhat. Also the logging of resources indicates exactly which class::subclass::subsubclass a resource is declared in, so I know where to go hunting to make a change to it. In practice I'd make judgement calls about when to split a class into subclasses based on operating systems or to nest if/else statements in a class based on how complex the class was getting, and so I'd have a mixture of both. That's fair enough. I found the consistency quite useful when working in a team, so it became a familiar pattern across every module in this case - even if that meant some classes were empty. -- Dominic Cleal Red Hat Consulting m: +44 (0)7818 512168 -- You received this message because you are subscribed to the Google Groups Puppet Users group.

Re: [Puppet Users] require? before? I need to have a dependency in place . . .
Guy, To requery the facts during would, most likely, invalidate your catalogue for that run. I've handled this by doing the work over 2 puppet runs. I have a custom fact that requires an X display (thanks to an install app that requires X display, even when using command line options and silent mode). If the custom fact returns it's default value (ie. the install app can't/hasn't run), I don't do anything with that app in the current puppet run. The particular class then just installs the ruby gem headless so the fact can use it on the next execution.

[Puppet Users] parameterised classes via LDAP how?

[Puppet Users] Client vs server storeconfigs
Hi all, As I understand it, storeconfigs needs to be enabled on both the agent and the master to function ideally. I have a couple of questions: - Can the various agents and the master safely share the same storeconfigs db (say, a postgresql server)? Is there any benefit to setting things up this way? - Is there any benefit for an _agent_ to use an RDBMS vs sqlite for its storeconfigs, since there is no db contention problem on an agent? Thanks for any guidance, -Taj. -- You received this message because you are subscribed to the Google Groups Puppet Users group. To post to this group, send email to puppet-users@googlegroups.com.

Re: [Puppet Users] Client vs server storeconfigs
Thanks for the reply Ohad, On 04-Jun-11, at 9:43 AM, Ohad Levy wrote: [snip] the database exists only on the server side Okay. I am seeing /var/lib/puppet/state/clientconfigs.sqlite3 even on machines running only the agent. I have [main] ... storeconfigs = true thin_storeconfigs = true dbadapter = sqlite3 on all machines, with the master overriding with dbadapter = postgresql. Is the clientconfigs.sqlite3 file related to storeconfigs? If so, is it simply being created and ignored by the agent? Apologies if I'm asking silly questions, I'd appreciate a pointer to an RTFM, it's possible I have missed something. -Taj. -- You received this message because you are subscribed to the Google Groups Puppet Users group.
