ansible - 思科 IOS 和 "reload" 命令
ansible - cisco IOS and "reload" command
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：
#reload in 30
Reload scheduled in 30 minutes by admin on vty0 (192.168.253.15)
Proceed with reload? [confirm]
似乎 ios_command 模块不处理这种情况。
我的配置：
tasks:
- name: do reload in case of "catting off"
ios_command:
commands: reload in 30
commands: y
provider: "{{ cli }}"
剧本的回应：

我该如何处理？
更新：
如果我尝试像这样在 YAML 文件中使用 expect 模块：
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

已更新
我已经安装了ansible 2.3并尝试如下：
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。在按下 "y" 后，重新加载命令的额外确认没有 "Enter"，所以这可能是另一个问题。

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？
仅限 Ansible 2.2
你可以使用这样的东西：
- name: send reload command inc confirmation
ios_command:
commands:
- reload in 30
- y
wait_for:
- result[0] contains "Proceed with reload"
provider: "{{ cli }}"
未测试，但类似于 ios_command 模块的最后一个示例。
不过请注意 Ansible 2.2，它尚未发布，新版本的 Ansible 可能会有明显的性能下降。
Ansible 2.0+ 包含 expect module，但需要在远程设备上使用 Python，因此它无法在 IOS 或类似设备上运行。
ios_command 模块的 commands 参数需要一个 YAML 格式的命令列表。但是，在提供的代码示例中，commands 参数被设置了多次。像这样尝试 ios_command 任务：
- name: do reload in case of "catting off"
ios_command:
commands:
- reload in 30
- y
provider: "{{ cli }}"
看来最简单的方法是使用 'raw' 模块向设备发送原始 SSH 命令。
这避免了必须使用 expect 和使用 ios_command 模块。
原始模块将运行命令而不关心设备的响应或提示。
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。它适用于 ansible，因为 ios 的默认提示会返回（重新加载在 1 分钟内触发）。
此致，
西蒙
下面使用 ansible-playbook 2.9.0 和 Python 3.7 为我工作。请注意，与 - command 一致，确保使用双引号 " 而不是单引号 '。并且不要忘记在命令末尾添加 \n。
- name: Reloading switch using ios_command.
ios_command:
commands:
- command: "reload\n"
prompt: 'Proceed with reload? [confirm]'
answer: "\r"
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：
#reload in 30
Reload scheduled in 30 minutes by admin on vty0 (192.168.253.15)
Proceed with reload? [confirm]
似乎 ios_command 模块不处理这种情况。 我的配置：
tasks:
- name: do reload in case of "catting off"
ios_command:
commands: reload in 30
commands: y
provider: "{{ cli }}"

gather_facts: False
# connection: local
tasks:
- name: do reload in case of "catting off"
expect:
command: reload in 30

已更新
我已经安装了ansible 2.3并尝试如下：
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。在按下 "y" 后，重新加载命令的额外确认没有 "Enter"，所以这可能是另一个问题。

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？
仅限 Ansible 2.2
你可以使用这样的东西：
- name: send reload command inc confirmation
ios_command:
commands:
- reload in 30
- y
wait_for:
- result[0] contains "Proceed with reload"
provider: "{{ cli }}"
未测试，但类似于 ios_command 模块的最后一个示例。
不过请注意 Ansible 2.2，它尚未发布，新版本的 Ansible 可能会有明显的性能下降。
Ansible 2.0+ 包含 expect module，但需要在远程设备上使用 Python，因此它无法在 IOS 或类似设备上运行。
ios_command 模块的 commands 参数需要一个 YAML 格式的命令列表。但是，在提供的代码示例中，commands 参数被设置了多次。像这样尝试 ios_command 任务：
- name: do reload in case of "catting off"
ios_command:
commands:
- reload in 30
- y
provider: "{{ cli }}"
看来最简单的方法是使用 'raw' 模块向设备发送原始 SSH 命令。
这避免了必须使用 expect 和使用 ios_command 模块。
原始模块将运行命令而不关心设备的响应或提示。
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。它适用于 ansible，因为 ios 的默认提示会返回（重新加载在 1 分钟内触发）。

下面使用 ansible-playbook 2.9.0 和 Python 3.7 为我工作。请注意，与 - command 一致，确保使用双引号 " 而不是单引号 '。并且不要忘记在命令末尾添加 \n。
- name: Reloading switch using ios_command.
ios_command:
commands:
- command: "reload\n"
prompt: 'Proceed with reload? [confirm]'
answer: "\r"
