Uncaught exception: Puppet::Error: Got nil value for user

[jaambros]

Hi all,

I'm trying to deploy a rails 3.2.17, ruby 2.1 application and I'm getting this error:

    triggering before callbacks for `deploy:create_symlink'
  * 2014-09-15 19:24:02 executing `moonshine:apply'
  * executing "sudo -p 'sudo password: ' RAILS_ROOT=/var/www/tek32/releases/20140916022332 DEPLOY_STAGE=tek32_lab RAILS_ENV=production shadow_puppet   /var/www/tek32/releases/20140916022332/app/manifests/application_manifest.rb"
    servers: ["tek32"]
    [tek32] executing command
 ** [out :: tek32] Uncaught exception: Puppet::Error: Got nil value for user
 ** [out :: tek32] /usr/lib/ruby/gems/2.1.0/gems/puppet-3.6.2/lib/puppet/type.rb:646:in `[]='
[ the rest of the stack dump is below]

I'm not sure what "user" variable is getting a nil value.
The one in config/moonshine.yml is set as
:ruby: src21
:user: rails

I've updated moonshine to the latest version, to no avail.
I've set the :user variable in config/deploy.rb
I'm out of ideas on how to fix this problem.
Any sugestions?

This version is a migration from a 2.3.18, 1.8.7 that deploys fine, and I have made no changes (relevant to moonshine).
That makes it even more puzzling to me.

Thanks in advance,
Jose

Make sure that puppet's the latest version:

cap shell

sudo gem install shadow_puppet

And then make sure that the config directory isn't in the shared_children section in config/moonshine.yml.

Did you update moonshine and run cap ruby:upgrade to get the server up to ruby 2.1?

Hi Kevin

It seems like making sure config is not in shared_children did the trick.

Thanks a lot for your help!!

Hey Kevin,

Please note that the Configuration page https://github.com/railsmachine/moonshine/wiki/Configuration lists config in the shared_children section.
I think that's where I got the idea from ...
MIght be a good idea to take it out there.

Best and thanks again,
Jose
