禁用Hiera调试日志记录

Question

我使用Hiera（ruby库，不是命令行工具或puppet集成）从现有的Hiera YAML（我们用于puppet使用）检索数据，用于Capistrano 。我能够得到这个工作的目的......但我似乎无法摆脱调试输出，这似乎是默认的：

$ sudo cap deploy

目前这仅仅是一个烦恼比什么都重要，但扩展输出（我已经修剪了上面的输出）使得日志记录相当嘈杂，我希望能够摆脱它。

我设法通过deploy.rb内设置配置哈希在hiera调用排序了这一点：

def hiera_lookup(key,default=nil,order_override=nil,resolution_type=:priority) 
    hiera_yaml = File.realpath('./puppet/hiera.yaml') 
    config = YAML.load_file(hiera_yaml) 
    config[:logger] = 'noop' 

    scope = YAML.load_file("/etc/hiera/hiera.conf") 
    hiera = Hiera.new(:config => config) 

    hiera.lookup("#{key}", default, scope, order_override, resolution_type) 
end 

设置config[:logger]关键“空操作”完全压制来自hiera输出。
