Re: [Puppet Users] Re: Few questions about Puppet
Hi Rich,
Thanks for the reply. May be I'm trying to do what puppet is not designed
for. I had the requirement of replacing a directory with another directory
and then run a script to test certain things with that directory content,
and once that completed I wanted the same directory to be replaced with a
completely different directory and run another script. The problem is how
do I replace the same directory twice at two different times? That's why I
told, this may not be achievable in puppet, because it's not designed to
perform these sort of works.
thanks,
Shazni

Maybe part of the confusion comes from you thinking of manifests as
scripts. They're not. With Puppet what you're doing is specifying what you
want the running state of the system to be. And for a given resource, like
a file, that's one state. And every time the agent runs, it will make sure
the resource is in that state.
In fact by default Puppet may not do things in a given manifest in the
order that they appear in the manifest, unless you do something
specifically to control that. There's a doc on resource ordering here:

The problem is how do I replace the same directory twice at two different times? Puppet is not a script engine; it is a state management service. You describe a target machine state to Puppet, and Puppet puts the machine into that state. You cannot declare two different target states for the same physical resource because it does not make sense. The longstanding system design in fact enforces a stronger constraint that you cannot declare the same resource twice, even with the same properties. You cannot manage the same resource into two or more different states during the same Puppet run. You could conceivably perform multiple runs, perhaps selecting which test to perform via tags, but at that point you have to consider why you are using Puppet for the job instead of some other system for which it is a more natural fit. That's why I told, this may not be achievable in puppet, because it's not designed to perform these sort of works. Oh, it's achievable. At worst, you can write up a shell script that performs the whole job, including file manipulation, and have Puppet run it via an Exec resource. I think, however, that you might be looking for an automated testing framework as your top-level system. You could perhaps integrate Puppet into your system at a lower level, using it (say) on a per-test-case basis to set up your test fixtures.

[Puppet Users] Re: Few questions about Puppet
Hi Shazni,
1. I've a json file shown below that I need to modify, when I run my puppet

In this case you can explore the puppet *augeas* resource type. It will
allow you to change the file contents.
But you have to learn the augeas tool format.
Refer,

puppet does not allow you to perform operation on same file twice in
manifests.
You have to do the all operations on single file in one file resource(*Exactly
once*)
3. I want to run a script file, which in turn invoke some java class
files. How to to do it in the same file?
Transfer the script file to puppet agent/client using *FILE* resource and
then use *EXEC* resource to execute that script file.
Hope this will help.
