我正在使用 Hiera（ruby 库，而不是命令行工具或 puppet 集成）从现有的一组 Hiera YAML（我们确实用于 puppet）中检索数据，以便在 Capistrano 中使用。我能够按预期工作......但我似乎无法摆脱似乎是默认的调试输出：

目前这只是一个烦恼，但扩展输出（我已经修剪了上面的输出）使日志记录相当嘈杂，我希望能够摆脱它。

我设法通过在 deploy.rb 中的 hiera 调用中设置配置哈希来解决这个问题：

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

将config[:logger]键设置为“noop”完全抑制了 hiera 的输出。
