考虑下面的代码：
node["cloudwatch"]["alarms"].each do |metric,keys| script_name = "/root/.cloudwatch/create_cloudwatch_alarm-#{metric}.sh" template script_name do source "cloudwatch/create_cloudwatch_EC2_alarm.sh.erb" owner "root" group "root" mode "0655" variables( :metric => metric, :description => keys["description"], :statistic => keys["statistic"], :comparison => keys["comparison"], :threshold => keys["threshold"], :evalperiods => keys["evalperiods"], :period => keys["period"] ) notifies :run, "bash[populate-create_alarms]", :immediately end bash "populate-create_alarms" do user "root" cwd "/root/.cloudwatch/" code <<-EOH echo #{script_name} >> ./create_alarms.sh EOH action :nothing end end 这运行良好，但在日志中我几次得到以下警告：
WARN: Cloning resource attributes for bash[populate-create_alarms] from prior resource (CHEF-3694) WARN: Previous bash[populate-create_alarms]: /var/chef-solo/cookbooks/soapp/recipes/cloudwatch.rb:220:in `block in from_file' WARN: Current bash[populate-create_alarms]: /var/chef-solo/cookbooks/soapp/recipes/cloudwatch.rb:220:in `block in from_file'
我明白为什么我会收到警告，但我不知道如何避免。 很明显， "populate-create_alarms"不应该在node["cloudwatch"]["alarms"].each ，但是我不知道如何将#{script_name}传递给"populate-create_alarms" 。 任何人都告诉我这样做的正确方法？
使bash资源名称唯一，例如下面的代码：
bash "populate-create_alarms-#{metric}" do .. end
