我有一个现有的chef-solo项目，我试图添加vagrant支持。我通常使用knife在EC2服务器上使用Canonical公布的Ubuntu 10.04 AMI来烹饪这些食谱。Vagrant需要属性roles.json中打破现有厨师项目
流浪要求我加chef_type和json_class属性，我的工作roles/*.json文件，像这样：
{
"name": "memcached",
"chef_type": "role",
"json_class": "Chef::Role",
"run_list": ["base", "memcached"]
}
如果我不这些添加到角色定义文件，然后我得到这个下一个错误。据推测，这些属性告诉厨师将我的JSON文件视为Chef :: Role类的实例。

然而，当我尝试做饭EC2相同角色的chef_type和json_class属性存在突破的过程中，产生了一个错误。这大概是因为在这种情况下，厨师要像对待一个Ruby散列我的角色定义（并从中调用.delete）

当我删除了chef_type和json_class我的EC2烹饪脚本回去正常工作，但随后流浪者被打破了。
我在chef-solo命令和Vagrant使用的主要区别在于，我的chef-solo命令与我的roles.json文件有直接关系，而Vagrant's则包含在dna.json文件中。
矿：
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
是否有某种方式，我可以配置我Vagrantfile做这些工作？
