Intermittent problem when provisioning with vagrant


#1

Hi Chefs,

I’m building a cookbook for an application. It’s basically a set of gearman workers who convert videos, images and PDFs. I’m using Vagrant and Berkself for developing and testing the cookbook.

This provisioning in Vagrant fails intermittently though, making the whole experience a bit painful at times.

I created a gist with the relevant information (command output, log and attributes file where the error seems to be happening): https://gist.github.com/3932926

Please note that it doesn’t happen all the time, and usually when it does, if I keep issuing “bundle exec vagrant provision” it will eventually work (without me changing anything in the cookbook).

I’m kinda clueless, being new to Chef myself I don’t know where to look for the error.

Thanks!

It looks like the attribute node[:zynk] is nil at the time the default
attribute file is loaded. Where is the value for 'node[:zynk][:appdir]'being
set?

Also, you should not use nested attributes (like what you have on line 1)
in your attributes file as Chef cannot guarantee the ordering of when
attributes are set from (attribute files, roles, environments…). I am
guessing this is your issue.

There was a recent discussion about this,

That attribute is originally set on the zynkbase cookbook, which is loaded as a dependency.

If I understand the discussion you linked correctly, one possible solution would be to set the node[:gearman][:dir] attribute in the zynkconverter default recipe, is that correct?

Thanks for your help!

Yes I believe that should fix your problem

This is a slightly different issue. What’s happening here is you’re getting bit by nondeterministic load order of attribute files. There’s been a lot of discussion on this bug/topic recently as well, but anyway, the way to fix it is to use include_attribute "zynkbase" in zynkconverter/attributes/default.rb, which will ensure that attributes file loads first.

If you upgrade the version of Chef inside your VM to 10.14 you will see the absolutely amazing error reporting that Dan and friends put into the latest version of Chef.

This will help you identify cookbook problems a lot easier and faster!

I kind of missed the difference here. :slight_smile:

Either way, I tried both approaches. Both seem to work fine (I say “seem” because it’s intermittent, so it could be that I’m just being lucky…). I like the include_attribute approach better, though, since it allows me to keep the recipe attribute-free.

Thanks for all the input, I’ll come back here if it bites me again!
