Re: Execution order of classes in a node

Hi.

I have three modules in my puppet/modules - 

1. jdk_installer
   
2. weblogic_installer
   
3. wldomain_create
   

Each of them have one class (same names as modules).

I have a node in site.pp which calls these 3 classes. And these classes need to be executed in a particular order. This is what I have in site.pp - 

node "devdomain.org"{

$config = hiera('domaincreation')

class{'jdk_installer':

 }

class{'weblogic_installer':

   require => Class["jdk_installer"],

}

class{'wldomain_create':

   require => Class["weblogic_installer"],

}

}

Execution order that I am trying to implement is first - jdk_installer followed by weblogic_installer and ending at wldomain_create.

When I run the puppet agent --verbose --test from the agent node, in the output it even looks like it is executing in the correct order. But towards the end, when it is running the wldomain_create class, it errors out saying the domain is already created; as if this class was already ran. Here's the last part of the output -

After execution completes, I see yep, the domain is there. I rm -rf the whole user_projects directory and run the puppet agent again. And I get the same error.

The wldomain_create class itself is not wrongly coded. If I comment out everything else other than that, i.e.

node "devdomain.org"{

$config = hiera('domaincreation')

class{'wldomain_create':

}

}

This runs just fine and creates the domain. (provided I already have jdk and weblogic installed, of course).

Anyone has any ideas what exactly is happening here? Even though it looks like it is executing classes in the order, it ends up creating the domain first. What's wrong here?

If you apply only the first two classes to a clean system, does the domain get created?  I bet it does.

Yes, if I run the first two classes first and then separately run the
wldomain_create class, it creates the domain successfully. When I run all of
them together, in that order, that's when it fails. I'm baffled.

[jcbollinger]

That's not what I meant.  If you apply ONLY the first two classes, and not the third, then does the domain get created?

In any case, the behavior you observe is surely related to the details of the modules involved.  As such, I can only guess about causes without having the modules to examine.  Nevertheless, my guesses are sometimes pretty good, and in this case I suspect you have a containment problem.  See the docs (http://docs.puppetlabs.com/puppet/3/reference/lang_containment.html) for an explanation of the issue and a possible solution.
