Question

我和厨师一起安装了几台服务器。其中一个在运行时开始失败

sudo chef-client -j /etc/chef/first-boot.json

仅在其中一台机器上

调试时，错误是

Re-raising exception: NoMethodError - undefined method `[]' for nil:NilClass

跟踪

  /opt/chef/embedded/lib/ruby/gems/2.3.0/gems/chef-12.18.31/lib/chef/event_dispatch/dispatcher.rb:34:in `call_subscribers'

该行是

metadata["node_uuid"]

通过阅读data_collector_metadata.json文件

来获取元数据

    def metadata
              Chef::JSONCompat.parse(Chef::FileCache.load(metadata_filename))
   rescue Chef::Exceptions::FileNotFound
          {}
 end

我正在努力解决这个问题......为什么这会在某些服务器上运行，而且它不会

找出问题所在。不同之处在于厨师 - 客户版本启动脚本使用最新版本重新安装厨师。使用这个bash

curl -L "https://www.opscode.com/chef/install.sh" | bash

我已修改为特定版本的bash

curl -LO https://omnitruck.chef.io/install.sh && sudo bash ./install.sh -v 12.15.19 && rm install.sh

它有效

厨师客户端无法读取机器元数据
