Question

我正在使用厨师独奏来测试我的食谱。我正在尝试使用库来触发电子邮件。这就是我所做的。

在我的cookbook目录中创建了一个库目录

cat /tmp/chefrepo/cookbooks/poc/libraries/helper.rb
require 'net/smtp'

module HandlerSendEmail
  class Helper

    def send_email_on_run_failure(node_name)

      message = "From: Chef <chef@chef.io>\n"
      message << "To: Grant <grantmc@chef.io>\n"
      message << "Subject: Chef run failed\n"
      message << "Date: #{Time.now.rfc2822}\n\n"
      message << "Chef run failed on #{node_name}\n"
      Net::SMTP.start('localhost', 25) do |smtp|
        smtp.send_message message, 'chef@chef.io', 'grantmc@chef.io'
      end
    end
  end
end

一个简单的食谱

cat /tmp/chefrepo/cookbooks/poc/recipes/default.rb
#
# Cookbook:: poc
# Recipe:: default
#
# Copyright:: 2017, The Authors, All Rights Reserved.
ruby_block 'fail the run' do
  block do
    fail 'deliberately fail the run'
  end
end

Chef.event_handler do
  on :run_failed do
    HandlerSendEmail::Helper.new.send_email_on_run_failure(
      Chef.run_context.node.name
    )
  end
end

当我使用chef-solo -c solo.rb -j node.json运行厨师独奏时我得到了

Running handlers:

[2017-09-29T12:49:09+00:00] FATAL: Chef::Exceptions::ChildConvergeError: Chef run process exited unsuccessfully (exit code 1)

我缺少什么？我尝试将库目录位置更改为与cookbooks目录相同的级别，但它不起作用。

您错过了混合助手资源的命令。在库文件的底部添加以下

Chef::Recipe.include(HelperSendEmail) Chef::Resource.include(HelperSendEmail)

这将使您的资源可用。
