w00t.

Thanks, Matt.

It was my misunderstanding of how an array attribute looks in json that was the issue. Thanks for showing me what it should look like.

Changing this:

  "override_attributes": {

    "yum": {

      "exclude": "kernel*",

      "installonlypkgs": {

      }

    }

  }

 

to your suggestion:

  "override_attributes": {

    "yum": {

      "exclude": [ "kernel*" ],

      "installonlypkgs": {

      }

    }

  }

Made it work.

Thanks again,

Cooper

Just looking at it now, there seems to be some inconsistency in that cookbook.  The metadata file and the example in the comments of attributes/default.rb suggest that the attribute should be a string made up of space-separated arguments.  However, both templates call #join on it (which strings don't have)

It would seem that the attribute should be an array.  If so, it you would specify it with something like:

"override_attributes": {



    "yum": {



      "exclude": [ "kernel*" ],



      "installonlypkgs": {


      }

    }
  }

I think.  FWIW, I mostly stick with Ubuntu, so my familiarity with yum is only passable.

I thought that's what I was doing with that json in the role:

  "override_attributes": {




    "yum": {




      "exclude": "kernel*",




      "installonlypkgs": {




      }


    }
  }

That entry is what causes the fatal error when I run chef-client on the node.

Is my json is set up wrong for this overriding attribute?

Thanks,

Cooper

Pretty sure it is an array attribute. So you need to put something like ..yum.exclude = [ "kernel*" ] in your role.  It used to be a default of the recipe, if I am not mistaken.
sent from my phone, excuse any nonsensical autocorrect stuff.

Hello.

I would like to exclude certain packages in my yum.conf file but I can't figure out how to do it with the Opscode yum cookbook.

I see this in attributes/default.rb:
# Example: override.yum.exclude = "kernel* compat-glibc*"
default[:yum][:exclude]

And this in templates/default/yum-rhel6.conf.erb:
<%- if node[:yum][:exclude] %>
exclude=<%= node[:yum][:exclude].join(" ") %>
<%- end %>

I tried putting this in the attributes:
default[:yum][:exclude] = "kernel*"

But that didn't do anything.
Not sure where to put the override.
I tried putting this in the role override_attributes:  https://gist.github.com/2832357
But that gave me a fatal error:
FATAL: Chef::Mixin::Template::TemplateError: undefined method `join' for "kernel*":String

Can anyone tell me how to add excludes to the yum.conf file with the yum cookbook?
Thanks,
Cooper
