[Puppet Users] Puppet 4 Certification

[muhammadausafaliyousaf]

Can anyone guide us on how to prepare for Puppet 4 Certification, like what 
books, links etc to use. Moreover, please suggest materials excluding 
Official training Materials but equal in caliber. Has anyone passed the 4 
exams yet?

as I am a Puppet Trainer, I must re-certify everytime when Puppet updates the 
questionaire catalog.

I can recommend the learn.puppet.com website with all the free online sessions.
Beside this it is useful to also dig into Puppet Enterprise as some questions 
will deal with PE Console. Best way to do this is using the learning vm from 
Puppet.

Additionally you can go for the following books:
- John Arundel - Puppet Cookbooks (I am unsure whether a Puppet 4 Cookbook is 
available - but basics still fit)
- Martin Alfke (me) and Felix Frank - Puppet 4 Essentials (Basics)
- Jo Rhett - Puppet 4 (Experienced)
- Alessandro Franceschi - Extending Puppet (Experienced)

Best thing you can do: work regular with Puppet.

BTW: there is no specific Puppet 4 certification.
Certification will never expire but has the year of the certification mentioned 
in the title.

hth,
Martin

Re: [Puppet Users] How to set noop = true in manifest for custom function?

[staceytian4321]

Hi Rob,

Thank you for the reply.

The missing comma is a type in the post. In my actual test, I had the comma.

I figured out how to enable noop = true for my custom function.

I edited my custom function

from
{:name => package, :ensure => "latest"}
to
{:name => package, :noop => true, :ensure => "latest"}

Thanks,
Stacey.

[Puppet Users] puppet-archive

[Ryan Vande]

I posted this in slack puppet community, lets see if I can get more ideas 
here 

I have the following setup

when puppet runs on the agent puppet node, no errors happen but nothing 
else happens either, have a look please 

Im using Puppet Archive for the following 

Puppetfile:
mod 'puppet-archive', '1.3.0'
mod 'puppetlabs-stdlib', '4.16.0'


hieradata/global.yaml:
artifactory_host: artifactory.azcender.com
tripwire::wintripdir: 'c://temp'


Profile:

include ::archive
archive {"${windir}/te_agent_8.4.2_en_windows_x86_64.zip" :
  ensure=> present,
  source=> 
"http://${artifactory_host}/artifactory/application-release-local/gov/usda/fs/busops/cio/Tripwire/te_agent_8.4.2_en_windows_x86_64.zip";,
  extract   => true,
  extract_path  => $windir,
  creates   => $windir,
  cleanup   => false,


Puppet agent runs on the puppet node without error but nothing happens , 
meaning no files are uploaded and extracted to the node 
Any assistance is much appreciated

creates   => $windir,


^^^  I'm fairly certain that this resource won't run if that file exists, 
which is most likely a directory (and does exist). I'd say it has to be 
this:


  creates   => "${windir}/te_agent_8.4.2_en_windows_x86_64.zip"

[Puppet Users] Re: puppet-archive

[Luke Bigum]

Actually no, it's going to need to be some file that's inside the ZIP 
archive, not the name of the ZIP archive itself. You get the idea though.

[Puppet Users] How to send console notice to notify email?

[staceytian4321]

Hi,

I am using open source puppet 3.7.3 master and client.

I would like to send the notice output of a manifest to email (I don't want 
to receive email about all manifests' notice, just this special manifest). 

In /etc/puppet/tagmail.conf:
pkgNotSync_notice: myem...@hotmail.com

Then I created a new manifest called "pkgcheck" which will call a custom 
function. This custom function (
http://ryanuber.com/11-06-2012/manage-sets-of-packages-in-puppet.html) is 
called "apply_package_list". It will check what packages are missing or 
with incorrect version. This function accepts two argument and has no 
return value. 

Then I created /etc/puppet/modlues/pkgcheck/manifests/init.pp and 
checkpkg.pp.

In checkpkg.pp, I call this function first, then create a notify resource:

class pkgcheck::checkpkg inherits pkgcheck  {
 
   apply_package_list('/root/packagelist', 'nopurge')
   
   notify { 'packageCheck':
  noop=> true,
  tag => packageNotSync_notice, 
  } 
}

When I ran "puppet agent -t" on my client machine, the console displays 
exactly what two packages are not synced (caironmm-1.0.x86_64 and 
libkkc-0.2.1-9.el7.x86_64):

Notice: /Package[caironmm-1.0.x86_64]/ensure: current_value absent, should 
be latest (noop)
Notice: /Package[libkkc-0.2.1-9.el7.x86_64]/ensure: current_value absent, 
should be latest (noop)
Notice: /Stage[main]/Pkgcheck::Checkpkg/Notify[packageCheck]/message: 
current_value absent, should be packageCheck (noop)

However, in the email I received, it only contains the last line which list 
the overall result:

Mon Apr 03 10:48:25 -0400 2017 
/Stage[main]/Pkgcheck::Checkpkg/Notify[packageCheck]/message (notice): 
current_value absent, should be packageCheck (noop) 

I would like to receive the email which looks the same as what is displayed 
on the console for this manifest. 

Please advise how I can achieve this purpose?

Thanks,
Stacey

[Puppet Users] Re: puppet-archive

[Ryan Vande]

Can you explain further?

As of now, if I dont manually create 
${windir}/te_agent_8.4.2_en_windows_x86_64 which is actually 
c:\temp\te_agent_8.4.2_en_windows_x86_64 it blows up but creates never 
creates it otherwise

If I manual create the directories, the puppet cycle goes without error but 
the zip is never created/extracted to 
c:\temp\te_agent_8.4.2_en_windows_x86_64

[Puppet Users] Re: puppet-archive

[Luke Bigum]

>From the docs at https://github.com/voxpupuli/puppet-archive#reference 
(Resources -> Archive section):

  creates: if file/directory exists, will not download/extract archive.

If you've got a creates parameter with the value of ${windir} (which for 
you is C:\temp\) then the archive resource won't do anything if C:\temp\ 
exists. On a Windows machine I believe there's a very good chance that will 
always exist, hence why your archive is not doing anything.

The creates flag is there to stop the archive resource from running over 
and over again; it specifies a file that will exist AFTER you've downloaded 
and extracted your archive.  Think of it as a conditional to do work or not 
do work.

I've downloaded /te_agent_8.4.2_en_windows_x86_64.zip and looked inside. I 
would suggest you try this parameter:

  creates => "${windir}/te_agent_8.4.2_en_windows_x86_64/te_agent.msi"

[Puppet Users] Webinar on Choria.io and NATS

[Brian Flannery]

Hi all..for those of you using Puppet 4, you may find the webinar we are 
doing later in the month with R.I. Pienaar on Choria  
(simplifies 
install/config of MCollective) interesting. 

Just thought I'd share; you can RSVP here: 
http://nats.io/blog/webinar-how-choria-significantly-improves-operability-of-mcollective-using-nats/

noise, or so it seems.

Thanks Michael.

 Puppet modules on Github are a good source. I've found a simple one:

 https://github.com/puppetlabs/puppetlabs-apache/blob/master/
 lib/facter/apache_version.rb

 And one of my own that's a little more complicated:

 https://github.com/LMAX-Exchange/puppet-networking-example/
 blob/master/lib/facter/interface_ringbuffer.rb

 Hi Warron,

 Puppet executes the script directly, so you need the shebang line
 and you must ensure the file is executable.

 Peter, perhaps I misunderstood you; but, I thought I was supposed
 to be able to use bash or sh scripting to generate facters of my own

 The link you provided refers to a python script example.  It also
 adds a shebang line at the top of the script; do I need the shebang 
 line,
 or will Puppet simply execute the shell script with:
