Chef-如何重新启动VM并继续执行操作 [英] Chef - How Reboot VM and continue performing actions

问题描述

在厨师食谱中，我需要在执行某些操作
之后在节点上执行重新引导，并且在完成重新引导之后，我需要继续执行其他操作：

In a Chef recipe, I need to perform a reboot on a Node after doing some actions, and after the reboot is done, I need to continue doing another actions:

配方：
-动作1
-动作2
-重新启动
-action3
-action4...。

Recipe: -action 1 -action 2 -reboot -action3 -action4....

我检查了社区中一些现有的食谱：重新启动处理程序，chef-reboot，chef-restart，chef-dominous，但是我无法使它们中的任何一个起作用。

I have checked some existing cookbook in the community: reboot-handler, chef-reboot, chef-restart, chef-dominous, but I cannot make any of them work.

Chef中是否有某种方法可以得到我需要的东西？
请提供详细的示例。

Is there some method in Chef to get what I need? Please provide detailed examples.

非常感谢您的帮助。

推荐答案

This is a recipe of mine you can try.
# Cookbook Name:: reboot-test
# Recipe:: default

bash 'reboot' do
     cwd '/tmp'
      code <<-EOH
      touch reboot.lock
      chmod +x /etc/rc.d/rc.local
#     echo "/usr/local/bin/chef-client" >> /etc/rc.d/rc.local
      cp /etc/rc.d/rc.local /etc/rc.d/rc.local_bkp
      echo "/bin/chef-client" >> /etc/rc.d/rc.local
      reboot
      EOH
      ignore_failure true
      not_if do ::File.exists?('/tmp/reboot.lock') end
      not_if 'ls -lrth /tmp/reboot.lock'
     end

#This is where you need to code for the config automation like the execute #resource but before the bash resource "CHEF-CLIENT-#EXIT"

execute 'touch' do
     command '/bin/touch /tmp/suman.test'
     end

bash 'chef_client_exit' do
      code <<-EOH
      rm -rf /tmp/reboot.lock
#     sed -i '/\/usr\/local\/bin\/chef-client/d' /etc/rc.d/rc.local
#     sed -e '/^\/bin\/chef-client/d' -i /etc/rc.d/rc.local
#     sed -e '\|^/bin/chef-client|d' -i /etc/rc.d/rc.local
      cp /etc/rc.d/rc.local_bkp /etc/rc.d/rc.local
      rm -rf /etc/rc.d/rc.local_bkp
      EOH
      only_if 'grep -i chef-client /etc/rc.d/rc.local'
     end
