Including multiple time the same recipe with different attribute

Chef Infra (archive)
1

Hi,

I’m trying to deploy multiple java applications with the java wrapper
cookbook. What the java wrapper does is:

  • download the java wrapper, unpack it
  • copy files to a specified directory
  • create a service and start it.
    what it needs is:
  • the name of the the service and the place where to find the jars.

The java-wrapper works for a single application (I’ve shared the cookbook
on the site).
What I was planning to do was, for each application do something like:

  • recipe A:
    override[java-wrapper][name] = a
    include_recipe “java_wrapper”
  • recipe B:
    override[java-wrapper][name] = b
    include_recipe “java_wrapper”

hoping that the java_wrapper recipe would be called once with a attribute
and once again with b attribute. But what is happening is that the
"java_wrapper" recipe is run only once. After re-reading chef
documentation, I’m not even sure the attribute java-wrapper/name can have
value a and then b during a chef-client run.

What would be a good way to solve the original problem ?

You can expose the work that the java_wrapper recipe does as an LWRP:
http://docs.opscode.com/lwrp_custom.html. Another option might be using
the application_java cookbook, assuming it does things the way you need it.

thanks Greg for your answer, can a LWRP do the same as recipe ? I need to
download the java-wrapper zip file only once, and then copy it for each of
the cookbook that would need it. Where is the 'normal' place to put it so I
can check if it is there and don't re-fetch ?

Actually, it can even do that... you just have to access the run_context
to do it.

i would love to see some snippets :slight_smile: . this is tricky, as now you have to
do whole cookbook dependency resolution, and compiling them, which iirc can
not be done during the convergence phase.
