我有一個現有的chef-solo項目，我試圖添加vagrant支持。我通常使用knife在EC2服務器上使用Canonical公佈的Ubuntu 10.04 AMI來烹飪這些食譜。Vagrant需要屬性roles.json中打破現有廚師項目
流浪要求我加chef_type和json_class屬性，我的工作roles/*.json文件，像這樣：
{
"name": "memcached",
"chef_type": "role",
"json_class": "Chef::Role",
"run_list": ["base", "memcached"]
}
如果我不這些添加到角色定義文件，然後我得到這個下一個錯誤。據推測，這些屬性告訴廚師將我的JSON文件視爲Chef :: Role類的實例。

然而，當我嘗試做飯EC2相同角色的chef_type和json_class屬性存在突破的過程中，產生了一個錯誤。這大概是因爲在這種情況下，廚師要像對待一個Ruby散列我的角色定義（並從中調用.delete）

當我刪除了chef_type和json_class我的EC2烹飪腳本回去正常工作，但隨後流浪者被打破了。
我在chef-solo命令和Vagrant使用的主要區別在於，我的chef-solo命令與我的roles.json文件有直接關係，而Vagrant's則包含在dna.json文件中。
礦：
ssh [email protected] "cd /etc/chef; sudo env chef_environment=production chef-solo -l info -c config/solo.rb -j roles/memcached.json "
流浪者之歌：
cd /tmp/vagrant-chef
chef-solo -c solo.rb -j dna.json
是否有某種方式，我可以配置我Vagrantfile做這些工作？
