[chef] Re: Re: Chef Exception Handlers and gem dependancies

AJ,

Thanks for your pointers. I had the gem_package in there, but the wrong location. It was in the handler code file. I now have a working setup by making these two changes:

1) Call the gem_package resource in the recipe.

2) Insert gem "pony" at the top of my handler code.

Thanks again!

you can use gem_package during the compile phase:

gem_package "foo" do

action :nothing

end.run_action(:install)

This file does exactly what you are talking about, fwiw:

Hey Everyone,

I'm a bit confused on how to get a gem (or other resource) installed on a

machine that is a dependency for a Chef Exception Handler.

I'm using the EmailMe example from the wiki to familiarize myself with

writing handlers:

http://wiki.opscode.com/display/chef/Exception+and+Report+Handlers

I have the example working if I already have the pony gem installed, but

once I try to perform a run on a clean machine, I get:

FATAL: LoadError: no such file to load -- pony

After reading the following wiki page, I thought the proper place was to put

it above the handler code.

http://wiki.opscode.com/display/chef/Evaluate+and+Run+Resources+at+Compile+Time

However that results in:

FATAL: NoMethodError: chef_handler[MyOrganization::EmailMe]

(chef_handler::email_me line 25) had an error: NoMethodError: undefined

method `gem_package' for main:Object

I seem to be caught in a catch-22. The handler is evaluated during the

compile stage, but I need to install a gem which doesn't happen until the

execute. How are others doing this with gems or other dependancies not on

the system?

I'm using the chef_handler cookbook and pulling the chef handler via the

LWRP in a recipe.

Where is the best place to call gem_package? Thanks!
