Chef 客户端无法读取机器元数据

Question

我有几台服务器安装了厨师。 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

调试的时候报错

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

痕迹是

/opt/chef/embedded/lib/ruby/gems/2.3.0/gems/chef-12.18.31/lib/chef/data_collector/messages/helpers.rb:133:in `read_node_uuid'
  /opt/chef/embedded/lib/ruby/gems/2.3.0/gems/chef-12.18.31/lib/chef/data_collector/messages/helpers.rb:111:in `node_uuid'
  /opt/chef/embedded/lib/ruby/gems/2.3.0/gems/chef-12.18.31/lib/chef/data_collector/messages.rb:40:in `run_start_message'

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

线是

metadata["node_uuid"]

元数据是通过读取data_collector_metadata.json文件来的

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

我正在为此苦苦挣扎...为什么这在某些服务器上有效而在此无效

Answer 1

找出问题所在。 不同之处在于厨师客户端版本 启动脚本使用最新版本重新安装 chef。 使用这个 bash

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

我已经修改为特定版本的 bash

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

成功了
