ansible - cisco IOS 和“重新加载"；命令 [英] ansible - cisco IOS and "reload" command
本文介绍了ansible - cisco IOS 和“重新加载"；命令的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想向 Cisco IOS 发送命令reload in"，但需要确认该特定命令，如下所示:
I would like to send command "reload in " to Cisco IOS, but that specific command needs to be confirmed like below:
#reload in 30
Reload scheduled in 30 minutes by admin on vty0 (192.168.253.15)
Proceed with reload? [confirm]
好像 ios_command 模块不处理这种情况.我的配置:
It semms like ios_command module doesn't handle such case. My configuration:
tasks:
- name: do reload in case of "catting off"
ios_command:
commands: reload in 30
commands: y
provider: "{{ cli }}"
来自剧本的回应:

我该如何处理?
更新:
如果我尝试在 YAML 文件中使用 expect 模块，如下所示:
If I try to use expect module in YAML file like this:
name: some tests
hosts: sw-test
gather_facts: False
# connection: local
tasks:
- name: do reload in case of "catting off"
expect:
command: reload in 30
responses:
'Reload scheduled in 30 minutes by admin on vty0 (192.168.253.20)\nProceed with reload? \[confirm\]' : y
echo: yes

更新
我已经安装了 ansible 2.3 并尝试如下:
I've installed ansible 2.3 and tried as follows:
tasks:
- name: do reload in case of "catting off"
ios_command:
commands:
- reload in 30
- y
wait_for:
- result[0] contains "Proceed with reload"
provider: "{{ cli }}"
但是，我仍然收到错误消息.我认为这是因为 ios 模块总是等待提示作为响应.此外，在按下y"后，重新加载命令的确认没有Enter"，因此这可能是另一个问题.
But still, I get an error. I think that this is because ios module always wait for a promt as a response. And additionaly confirmation of reload command is without "Enter" after pressing "y" so this could be another problem.

谁能知道如何在 ansible 或 maby 中解决该问题，唯一的方法是使用纯 python 脚本或编写自己的 ansible 模块?
Can anyone have any idea how to resolve that problem in ansible or maby the only way is to use pure python script or write own ansible module?
推荐答案
您可以使用:
- name: reload device
ios_command:
commands:
- "reload in 1\ny"
provider: "{{ cli }}"
这将在 1 分钟内重新加载设备并接受重新加载提示.它对 ansible 很有效，因为 ios 的默认提示会回来(重新加载会在 1 分钟内触发).
This will reload the device in 1 minute and the reload prompt gets accepted. It works well for ansible because the default prompt of ios will come back (reload gets triggered in 1 minute).
