Playbook支持任务结果回显,不只是执行是否成功

ansible1.9.1版本
写callback插件功能实现

1.ansible.cfg配置文件(变更callback路径位置)
[defaults]
host_key_checking   = False
callback_plugins = /tmp/callback
2.编写回显callback脚本

cc.py文件名字可以自定义,但是里面的内容有具体要求

vim /tmp/callback/cc.py
#!/usr/bin/env python
# -*- coding=utf-8 -*-
######################
class CallbackModule(object):
    #执行成功的
    def runner_on_ok(self, host, res):
    #print res
        if 'stdout' in res.keys():
            print res['']
        if 'state' in res.keys():
            print res['state']
        if 'invocation' in res.keys():
            print res['invocation']
    #执行失败的
    def runner_on_failed(self, host, res, ignore_errors=False):
        pass
    #执行跳过的
    def runner_on_skipped(self, host, item=None):
        pass
    #主机不可达的
    def runner_on_unreachable(self, host, res):
        pass

是不是很简单,按照标注文件定义CallbackModule类,重写里面的runner_on_ok和runner_on_failed方法就好了,后面接的host,res,以及其他都是固定写法,不能

3.编写yaml文件

/tmp/test.yml

---
- hosts: all
  tasks:
  - name: test playbook
    shell: 'df -h'

/tmp/hosts

[task]
127.0.0.1
4.执行playbook
cd /tmp/
ansible-playbook -i hosts all test.yml -k
SSH password:

5.callback里面的插件host和res是固定写法,不能改

尝试print res看下里面的内容,大字典里面各种信息
