Puppet users - Sep 2013 - How to deploy & excecute script remotely

Hi,
 
I am new to Puppet & just had installed Puppet master on Centos.And manging 
Linux & Windows nodes, now I would like to deploy and execute script on one 
of my Linux Box Remotely from 
Puppet Master.
 
Appriciate your help. Pls. share steps to be followed for achieving above

Not hard at all...

just use "file" resource to deploy the file and then "exec"
to execute it:

file{ "/path/to/my/script.sh"
  source => "puppet:///modules/${module_name}/script.sh",
  mode => 755,
} ~>

exec { "/path/to/my/script.sh"
   refreshonly => true,
}

The important bit here is the ~> . That means notify and require. It 
basically means it will notify the exec when the file is deployed and that 
puppet will push the file before trying to execute it. The refreshonly true 
will assure you that the script will be executed only if it is notified.

Cheers

Juan

It depends on what you mean by that.  If the target node is already 
registered with the master, and the agent is running on a regular schedule 
(whether as a standalone service or via a scheduler service such as cron), 
then you can proceed more or less as JuanBrein described.  There are many 
variations, nuances, and caveats that he didn''t cover, but
I''ll hold off on
those for now, except this one: the approach described will result in the 
agent running the specified command as part of its next scheduled run.  If 
instead you want to deploy and run your script right away, then you need 
something more or different, such as MCollective, for example.

JuanBrein,
 
Can you pls.mention here, what activites do I have to perform on Master & 
nodes.
 
Will be very helpful.
 
Since I really dont know where this 
 "file" resource to deploy the file and then "exec" to
execute it:

I didnt see  "file" resource to deploy the file and then
"exec" option on
Puppet master. Is there any plugin I have to installed on Master & then 
these two options will be
visible on Puppet master dashboard. Or I have to do the changes in 
commandline. 
Seriousely, not aware which file to edit & move ahead. Need your help.

Raju,
 Being new to puppet, allow me to suggest the Learning Workshop -
https://puppetlabs.com/learn.

In conjunection with that, we have a set of free tutorials with a learning
VM ( http://docs.puppetlabs.com/learning/ ) that I feel may help alleviate
some of these questions.

Give that a shot. Thanks!

The File and Exec resource types are built-in to Puppet.  And they are *resource
types*, not classes, which is probably why you are not seeing them in 
Dashboard.  I strongly recommend that you avoid Dashboard and similar 
products until you have a reasonable grasp of core Puppet.  You do not need 
such products to use Puppet, and they will obscure some of the more 
fundamental details that you need to understand.  You should start with the 
documentation: http://docs.puppetlabs.com/puppet/3/reference/.  In 
particular, you should read the Puppet language reference, and you should 
at least skim the resource type reference in the "Generated
References"
section.

I have write the below script in puppet language on puppet master. Now 
wants to know that, I have to call this script to be excuted from puppet 
master on End points. How do I do that ?
 
Class users {
  file  { ''/opt/example.sh'':
     ensure => prsent,
     content => "#!/bin/sh\mkdir /opt/test123\n",
     mode   => ''0755'',
   }
 exec { "create test123":
    command => ''/opt/example.sh'',
    creates => ''/opt/test123'',
    require => File[''/opt/example.sh''],
 
 
Do I have to place this script on end point if yes...if I place it on end 
point how do I call it from Puppet Master 
What does this command do 
mco exec run script=''/opt/example/bin''

In the strictest sense, you *don''t* do that.  Not at all, ever.  It is
very
important for you to understand that one computer cannot run anything on 
another; all it can do is request that the remote computer run something 
itself.  Even that requires that the remote machine run some kind of 
program to receive and act on such requests.

In the most common Puppet usage paradigm, manifests such as the one you 
present reside on the master, and the Puppet agent periodically requests a 
compiled version (a catalog) from the master, which it (the agent) then 
''applies'' to its machine.  For this purpose, the agent can run
as a local
service (daemon) to automate the process on a regular schedule.  
Alternatively, it can be run periodically by a scheduler, such as cron, or 
on demand.

In addition, if the agent is running as a local service, then it can be 
configured to listen for messages from the master that instruct it to 
immediately initiate a catalog cycle.  That provides a mechanism by which 
the master can remotely induce the local machine to retrieve and apply its 
current catalog.

You do not need to place that manifest on the end point.  If you do put it 
there, however, then you can apply it via a ''puppet apply''
command executed
on that end point machine (as opposed to ''puppet agent'').

The ''mco'' command is part of the "Marionette
Collective" (MCollective)
system for cluster management.  MCollective belongs to PuppetLabs and 
interoperates with Puppet, but it is not part of Puppet.  Subject to 
several conditions and provisos, the command requests machines in the 
cluster to execute the named local command.  This sort of approach can be 
employed to remotely trigger ''puppet agent'' or
''puppet apply'' commands, as
long as the target machine is configured to support that.
