我应该在chef存储库中哪里写`node.default`变量？

Question

我想使用[chef-rbenv][1]食谱。

我在chef-repo顶级目录中创建了一个Berksfile，如下所示：

source "https://api.berkshelf.com"
cookbook 'rbenv'

并按berks vendor cookbooks安装了食谱。

然后我在服务器配置json文件中添加了"recipe[rbenv::user]"。

根据文档，我必须设置一个变量node.default['rbenv']['user_installs']来安装rbenv。但我无法弄明白我应该把它写在哪里。

有人能告诉我在哪里以及如何编写变量？

**我的环境（编辑）

我这样使用local mode：

$ sudo chef-client --local-mode -c solo.rb -j localhost.json

solo.rb

base = File.expand_path('..', __FILE__)
file_cache_path "/tmp/chef-solo"
cookbook_path ["#{base}/site-cookbooks", "#{base}/cookbooks"]
role_path "#{base}/roles"

localhost.json

{
    "run_list" : [
    "recipe[rbenv::user]"
    ]
}

Berksfile

source "https://api.berkshelf.com"

cookbook 'rbenv'

角色/ rbenv.rb

name "rbenv"

default_attributes({
                       'rbenv' => {
                           'user_installs' => {
                               'user'    => 'ironsand',
                               'rubies'  => ['1.9.3-p0'],
                               'global'  => '1.9.3-p0',
                           }
                       },
                   })

这是我运行命令时的错误：

通常你会把它放在一个角色或包装食谱中。如果您不熟悉Chef，那么角色可能最简单：

default_attributes({
  'rbenv' => {
    'user_installs' => whatever,
  },
})
