Trying to figure out if these would behave the same or not?
Example 1:
-----------------
class Foo {
require Bar
someresource { ''baz'':
…. # This depends on A,B and C being already completed
}
}
class Bar {
include A
include B
include C
}
Example 2:
----------------
class Foo {
include Bar
someresource { ''baz'':
….
require => Class[''Bar'']
}
}
class Bar {
include A
include B
include C
}
So will these behave the same? When I require Bar in the first example are the
A,B and C resources guaranteed to be executed before the resource in Foo? Same
question goes for example 2
Thanks for the clarification!

I''m not a puppet expert, but your situation would probably fit more with an usage of stages. It would allow you to define stages and order or those.

You need containment resources in class Bar.

The resources they contain are not guaranteed to be applied before Someresource[''baz''], but if there were any resources declared directly by class Bar then they would all be applied before Someresource[''baz'']. Do not use run stages for this. They are way overkill for the problem. If you needed to add new stages every time you had to enforce resource ordering then you would quickly end up with an unmanageable mess. See my response to your other thread on this question (https://groups.google.com/forum/?fromgroups=#!topic/puppet-users/buREmDC8Py4) for more information. In the future, it will suffice to ask your question once. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

You can also look at Stages if you like to separate the concerns (some classes should be after some other classes, but you do not want to record the exact classes as you may want to change them). You can create additional stages (there is a main stage by default), and assign classes to stages. See more here: http://docs.puppetlabs.com/guides/language_guide.html - "Run Stages".
