Chef-server 当目录操作删除失败时如何执行资源？

Question

有没有办法在资源失败时创建信息文件“日志”？我尝试了以下方法，但 ingnore_failure 使退出状态为 0，因此 bash 不会被执行

示例值

node.default['user']['option'] = ['delete','/home/vagrant/app/libs']
include_recipe 'user_configure::default'
# so the developer want to delete the folder /libs
# but i don't want to let him as the folder libs is not empty

# node.default['user']['option'] = ['delete','/home/vagrant/app/libs'] 
# the array working like that, [0] will always be the action and then the folders

然后我将另一本食谱称为 user_configure

case node.default['user']['option'][0]
when /create/i
      node.default['user']['dirs'].each do |dir|
      directory "#{dir}" do
      action :create
      recursive true
      end
    end
when /delete/i
  include_recipe '::delete'
when /modify/i
  include_recipe '::modify'
end

i = 1
while i < node.default['user']['option'].length
    directory "#{node.default['user']['option'][i]}" do
    action :delete
    ignore_failure true
    i += 1
    end
end


bash 'Cheking for error' do
    code <<-EOH
    if [ $? -ne 0 ]
        then
         echo 'Something want wrong with the chef-client at deleting folders!' >> /vagrant/$HOSTNAME_"#{Time.now}".txt
        fi
    EOH
  end

有没有办法挽救这个错误？ 我的主要目标是，当我失败时，我创建一个日志文件并将其移动到文件夹错误的 ftp 服务器中，以便开发人员可以查看 chef-client 是否没有完成任务

感谢 seshandri_c，经过一番研究，这里是解决方案

#on top of your recipe
directory '/root/errors_handle' do
  recursive true
end

cookbook_file "/root/errors_handle/log_handler.rb" do
  source 'log_handler.rb'
end

chef_handler 'LogModule::LogHandler' do
  source "/root/errors_handle/log_handler.rb"
  action :enable
end

然后在你的 cookbook_name/files/default 上

module LogModule
    class LogHandler < Chef::Handler
        def report
            if !success?
                Chef::Log.fatal('The chef-client has failed')
                status = "chef-client failed at #{Time.now.strftime('%Y-%m-%d %H:%M:%S')} for client #{node.name} at resource #{run_status.exception}\n"
                File.write("/vagrant/#{node.name}_#{Time.now.strftime('%Y-%m-%d %H:%M:%S')}.log", status)  
            else
            end
        end
    end
end
