Chef infra 厨师：gem依赖于提供者

我们正在为资源创建一个提供程序。它代表在给定数据库中创建mongo用户

class LivingMongoCookbook::UserProvider < Chef::Provider::LWRPBase 
  provides :living_mongo_user
  def whyrun_supported?
   true
  end
  def action_create
   db = Mongo::Connection.new(new_resource.host, new_resource.port).db(new_resource.database)
   users = db.getUsers
   db.createUser({ user: new_resource.user, pwd: new_resource.passwd, roles: [ new_resource.roles ]})
   new_resource.updated_by_last_action(true)
 end
end

class LivingMongoCookbook:：UserProvider

为了能够在db上创建用户，我们正在努力使用mongo ruby驱动程序。然而，我们得到了这样的信息：

似乎mongo驱动程序不可用

有什么想法吗？

假设你有一个最新的ish Chef版本，gem不需要C编译器，将

gem'mongo'

添加到

元数据中。rb

和Chef会帮你安装它。

添加

Chef_gem'mongo'

使用

编译时true

将gem安装到Chef中（在您的提供者运行（参见文档）Ho之前使用ruby，在调用它的类之前，您必须

要求使用“mongo”

。。。
