我应该在厨师存储库中的哪里写“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'

并由berks vendor cookbooks 安装说明书。

然后我在服务器配置 json 文件中添加了一个 "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。但我不知道该写在哪里。

谁能告诉我应该在哪里以及如何编写变量？

**我的环境（编辑）

我正在像这样使用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]"
    ]
}

伯克斯文件

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，您会将其放入角色或包装食谱中。如果您不熟悉 Chef，则角色可能是最简单的：

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