Is it possible that puppet could be modified to be used to manage
switches that have a command line based interface?

When I manage our Allied Telesis switches (which have a CLI similar  
to

cisco IOS) I wonder if I could control it via a puppet-like node:

node 'switch-101' {
  vlan { storage:
id => 1234,
untagged_ports => "3/e1, 4/e3",
tagged_ports => "1/e1-2/e48",
  }
  include gvrp
  include stp::rstp
  stp::portfast { "1/e1-e48,2/e1-48",3/e1-48": }
}


Now I know we probably can't get puppet to run on the switch, but  
we can
get a host to ssh or telnet to the switch, and to download the  
current

configuration of the switch.



It's feasible - you could create a type and provider that connects
to the switch and interacts with the CLI to retrieve the
configuration, manipulate it in some way (depending on how complex
the format is) and then send it back and apply it.

Obviously there would be limitations - no Factor facts and you'd
have to create a dummy node I guess because the switch wouldn't be a
real "node".

Others may have niftier ideas on how to do this - an easier
mechanism might be use Puppet's REST API to integrate with the
switches own management tool if it has an exposed API.


The way that I would implement this would basically to write a system  
that read in the whole switch config, used the catalog and RAL to  
compare states and write a new config, and then a hook at the end to  
write the new config.


You could use the (new in 0.25) pre and post transaction hooks to  
retrieve and store the switch config, and then it's just a question of  
having RAL types that modify that config in some way.


Make sense?

[Puppet Users] puppet for switches

David, just wanna say thanks for responding to this as it's driving me

You can try using a hex editor or similar to see what the actual 
corruption is.
David, I tried this and got absolutely nowhere. I'm willing to believe I 
am doing something wrong when analyzing the data, but the tests I've 
tried which I think will narrow down the corruption actually make it 
more difficult to diagnose. For example, if apt-proxys.cfg was having 
the problem, and i renamed the hostgroup to , it would then claim 
the error was in the next alphabetical hostname, say domino-servers, 
until i get past a few and it runs.


Also, can you post a minimal configuration example that causes the 
problem?
Here's the error: Error: Host ' ' specified in host group 'ad-servers' 
is not defined anywhere!


Here's the .cfg file:

define hostgroup {
hostgroup_name ZZ
alias Active Directory Servers
}

And I get this:

Error: Host ' ' specified in host group 'ZZ' is not defined anywhere!

It indicates to me that the file is fucked somehow. This is written out 
from an exported and collected resource. Is it possible database 
encoding comes into play here?





From where have you installed puppet? Packages, source? Can you 
confirm that the installation is pristine?


I make my own packages but they are basically just dsc's from 
ftp.ubuntu.org that I build for 8.04 LTS since the 8.04 LTS package is 
so old. They are installed via apt.
Are you using storeconfigs? Is there maybe something wrong in the 
database?
That's what I am wondering but I don't know what to look for. Things 
look fine. The file itself, looks fine. There's corruption at the byte 
level that isn't apparent to the human eye. Any idea what to check in 
the DB?


I've used the nagios types from 0.25.4 today and they worked flawlessly.

I know, I think I may have even taken some inspiration from your modules.



Best regards, David

Re: [Puppet Users] adding users help.

I want to be able to add additional resources to my virtual users,

someone could point me in the right direction, I’m guessing i need to
use a definition I’m just not sure on the best way to do it.


A definition is a good way, yes.  Like this:

define myuser($uid, $comment, ...)
{
user {
$name:
uid => $uid, comment => $comment, ...;
}
file {
"/home/$name":
ensure => directory, owner => $name, ...;
"/home/$name/.ssh":
ensure => directory, owner => $name, ...;
}
}

class our-users
{
@myuser { "aguy": uid => 1001, ...; }
@myuser { "agirl": uid => 1002, ...; }
@myuser { "analien": uid => 1003, ...; }
}

class storageadmins
{
include our-users
realize(User["aguy"], User["agirl"])
}

A slight modification is to declare if the user should be an admin
or not in the myuser definition.  Add a parameter $type to myuser
(without actually using it inside the definition), and do:

class our-users
{
@myuser { "aguy": uid => 1001, type => "storageadmin", ...; }
@myuser { "agirl": uid => 1002, type => "storageadmin", ...; }
@myuser { "analien": uid => 1003, type => "nonadmin", ...; }
}

class storageadmins
{
include our-users
Myuser <| type == "storageadmin" |>
}

It's up to your taste to determine which version is preferable.

hello,

Probably best to send this kind of thing to mcollective's mailing list rather 
than puppets :)

2000 nodes certainly is within my goals with the design, that said there has 
not been such a big deploy.

If any problems at all it will be related to the fast producer/slow consumer 
style problems.  In MC the consumer is very fast (it does very little) but 
still, should there be a problem it will be a fairly simple matter to convert 
the replies to go over a queue rather than a topic.  That should resolve any 
issue with it.

You'd probably want a few activemq instances in a cluster in such a setup, 
though I've heard of much larger client counts on activemq.

[Puppet Users] mcollective scalability

2010-05-04 Thread linuxdatacenter 
I've been thinking a lot about running mcollective on my production
servers recently, especially about its nice integration with puppet
(using facts and so on). However I've got some concern about its
scalability - how publish/subscribe middleware scales in terms of
speed and flooding the network. I run about 2000 servers. Has anyone
got any experience running mcollective on similar scale?

That's correct.

Next maintenance release is 0.25.5 - currently in testing.

Next feature release is Rowlff which doesn't have a version number
assigned as yet and is the final stages of being tidied up.

[Puppet Users] Introducing Scaffold

2010-05-04 Thread James Turnbull 
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I?ve just written and released Scaffold
(http://github.com/jamtur01/puppet-scaffold) ? a very simple Puppet
scaffolding templating tool. It integrates with Puppet to create a
variety of Puppet configuration and objects.

You can install it via a gem currently:

$ sudo gem install scaffold

It requires Puppet and will install the templater gem as a dependency.

You can then use it like so:

* Basic Puppet configuration (creates site.pp, fileserver.conf and
supporting material in the Puppet configuration directory):

$ scaffold puppet

* Modules (it checks the Puppet module path and creates the module
in the first module path it finds):

$ scaffold module module_name

* Nodes (assumes you?ve created the basic Puppet configuration and
creates nodes in Puppet configuration directory):

$ scaffold node node_name

* Classes and Definitions:

$ scaffold class module_name class_name

$ scaffold define module_name define_name

* Functions:

$ scaffold function module_name function_name function_type

The function type can be statement or rvalue and defaults to
statement if omitted.

* Types and providers:

$ scaffold type module_name type_name

I?d welcome feedback, testing, and ideas (and code!) on how to
extend it. The idea is that once we?ve got a strong working tool
we?ll look to integrate something like the result into Puppet
mainline as a provisioning and template system.

Regards

James Turnbull

Ah, sorry.  I missed that, somehow, and have never used the RPM provider.
I think other people have answered your questions there, though, which I hope
is helpful to you.

Thanks for not hating me for my failure to read for content. ;)

if you need this kind of control over your installed packages I would
recommend that you look for patch-/package-version-management into
spacewalk/satellite (if this is possible for your distro). It is imho
the better tool for that job.

Not that it is not possible to do that with puppet, but I see a certain
complexity that will sooner or later come up with controlling exact
package version over plain rpms with puppet.

What I imagine is that you control package installation (ensure =>
installed), config file management and service restarts etc. with puppet
and control the exact patch-level of applications with spacewalk/satellite.

As a sidenote: you might want to use defines to for example wrap up rpm
downloads and package installation. Also be warned that for larger file
downloads you should at least use 0.25.x and that (hopefully) the next
major release (codename rowfl) will finally clean up the remaining
issues with sourcing large files.

Dan,

does this mean it will be possible to have a template like this

 16 <% workers.each do |worker| -%>
 17 worker.<%= worker %>.type=<%= worker['type'] %>
 18 worker.<%= worker %>.host=<%= worker['host'] %>
 
 24
 25 <% end -%>

which can be pouplated with an external node definition like this one:

---
classes:
 - vim
 - users
 - templates_eval::testvars
environment: test
parameters:
  workers:
bo-01-010101:
type: ajp13
host: myhostname.net

And is this already available in the current beta release? I didn't
find anything in the release notes so far (concerning ERB templates,
though hashes are mentioned).

Thanks!
Bernd
