Absolutely, you can.  Puppet can deploy it as easily as any other
applicaton.  Where things become interesting is when you have to decide
whether to deploy and configure individual Java applications to JOnAS,
or how much of the configuration is done by puppet, how much through the
JOnAS console.  People have very different philosphical approaches to
that.  Nice to have the choice, though.

I second Nigel''s question.  I know a number of people who deploy Java,
Ruby, PHP, etc, etc applications with Puppet.

Can you guys describe the sort of applications you deploy, how they are
delivered to the target, and how you deal with "rolling bounces"
(start on node A, shutdown JVM, deploy code, start JVM, move to node B, etc.) ? 
Are you just doing this by ordering puppet runs externally?  If so, what manages
the ordering?

How do you tell puppet which version / package of the code to install?  Do you
generate manifests with this information?  Is it a fact?  extlookup?

I''d also be interested to know how / if you handle deployment of
multiple apps to the same container.  Imagine you have a dependency like this
(pseudo puppet code):

	app1: { require => [ exec[ "shutdown-jvm1"],
deploy["app1"], exec["start-jvm1"] ] }
	app2: { require => [ exec[ "shutdown-jvm1"],
deploy["app2"], exec["start-jvm1"] ] }
       
.. when you deploy app1 and app2 at the same time (ie, within the same puppet
run), are you able to make puppet only apply the first shutdown and the last
startup?  (basically, optimize it & just shutdown jvm1 once, deploy both
app1 and app2, then start jvm1.)  We do this today with home-grown code but
I''d like to move it into puppet if possible.

Thanks!
James

I''m just starting with puppet, but how about this as a solution to the
precedence and single-restart problem

 

1.       Define some stages 

 

stage { pre: before => Stage[main] }

stage { post: require => Stage[main] }

 

2.       Define a jvm class with the stages associated with the pre and
post:

 

class jvm { }

class jvm::jvm1 inherits jvm {

   $start = "/etc/init.d/jvm1 start"

  $stop = "/etc/init.d/jvm1 stop"

  @exec { "jvm1::stop": command=> $stop, stage=>pre }

  @exec { "jvm1::start": command=> $start, stage=>post }

  # In here add anything else you want to do for the jvm1 setup, eg global
settings

}

 

3.       Create a define to add a jvm deploy

 

define jvm::jvm1::deploy() {

     include jvm::jvm1

    realize( Exec[jvm1::stop], Exec[jvm1::start] )

  # add the necessary deploy commands here, file definitions, etc

    deploy( $name )

}

 

This might be overkill and I''m not 100% sure about my syntax, but you
should
be able to extend it to have multiple JVMs on the same machine.  The use of
the jvm::jvm1 class and the virtual resources for the exec''s makes sure
you
don''t end up with the start/stop multiple times and they only run if
required, and you can use the jvm::jvm1::deploy multiple times.  The stages
ensure that the stop it run before the deployment and the start is run after
deployment.  It might be possible to use parameterised classes with the jvm
class to set up the jmv::jvm1 classes but I''m not so familiar with the
syntax as yet.

 

The problem with doing the nodes sequentially might be possible using
resource chaining?
