chef-solo我有一个正在尝试添加vagrant支持的现有项目。我通常使用刀在 EC2 服务器上使用 Canonical 发布的 Ubuntu 10.04 AMI 烹饪这些食谱。

Vagrant 要求我在工作文件中添加chef_type和json_class属性，如下所示：roles/*.json

{
  "name": "memcached",
  "chef_type": "role",
  "json_class": "Chef::Role",
  "run_list": ["base", "memcached"]
}

如果我不将这些添加到角色定义文件中，则会收到下一个错误。大概这些属性告诉厨师将我的 JSON 文件视为 Chef::Role 类的实例。

但是，当我尝试在 EC2 上烹饪相同的角色时，存在chef_type和json_class属性会破坏该过程，从而产生下一个错误。大概这是因为在这种情况下，厨师希望将我的角色定义视为 Ruby 哈希（并.delete从中调用）

/usr/lib/ruby/gems/1.8/gems/chef-0.9.16/bin/../lib/chef/node.rb:379:in `consume_run_list': undefined method `delete' for #<Chef::Role:0x7fa337535138> (NoMethodError)

rake aborted!

当我删除chef_type和json_class我的 EC2 烹饪脚本时，我的 EC2 烹饪脚本恢复正常工作，但随后 Vagrant 坏了。

我看到我的 chef-solo 命令和 Vagrant 使用的命令之间的主要区别是我的 chef-solo 命令与我的 roles.json 文件有直接关系，而 Vagrant 的命令包含在dna.json文件中。

矿：

ssh ubuntu@ec2-xxx-xxx-xxx-xxx.us-west-1.compute.amazonaws.com "cd /etc/chef; sudo env chef_environment=production chef-solo -l info -c config/solo.rb -j roles/memcached.json "

流浪者：

cd /tmp/vagrant-chef
chef-solo -c solo.rb -j dna.json

有什么方法可以配置我的 Vagrantfile 以使这些工作？

While I haven't run into this particular problem, I have noticed that Chef, as a moving target, tends to have strange stuff happen like this if you're using the same recipes on different versions of Chef.

Just to eliminate that, the first thing I would try is to make my chef versions consistent. I see that your Vagrant VM is using version 0.10.0 and your EC2 VM is using 0.9.16 - whichever is more important, perhaps you could standardize on that one - e.g. if you're trying to replicate your EC2 system locally, you can recreate your Vagrant base box (or look into making your own, the documentation is pretty good on the Vagrant website) such that it more closely matches what you've got installed on EC2.

这应该在最新版本的 Chef 中得到修复。存在允许无限对象反序列化的 JSON 漏洞。我相信修复问题也将解决您在此处看到的问题。

试用 Chef 11 和 Vagrant 1.5.6
