以下是我的思科设备 ansible 配置的 yaml 文件。在 /etc/ansible/hosts 中，我还编辑了 hosts 文件以反映我的 Amazon EC2 Ami 实例，如下所示

[ec2-instances]
ec2-54-152-72-23.compute-1.amazonaws.com

下面的 YAML 文件

-  hosts: ec2-54-152-72-23.compute-1.amazonaws.com
   gather_facts: false
   connection: local

   tasks:
    -name:  Customer IOS Upgrade Initial Discovery
    cli_command: "{{ show }}"

    vars: 
      show:
       - show run
       - show version
       - show interface status
       - show license


    -mail:

      body: 'System {{ ansible_hostname }} has been successfully discovered.'
      delegate_to: localhost

    save_when: changed

尝试运行以下命令时，我收到以下错误消息。知道为什么会发生这种情况吗？我已切换了 [ec2-instances] 提供的初始 .yaml 文件中显示的内容，但运行时结果仍然没有变化。

ansible-playbook -i /etc/ansible/hosts test2.yml --user ec2-user --private-key=/home/adam/Desktop/EC2CSR1000v.pem -vvv
ansible-playbook 2.7.9
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/adam/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible-playbook
  python version = 2.7.15rc1 (default, Nov 12 2018, 14:31:15) [GCC 7.3.0]
Using /etc/ansible/ansible.cfg as config file
/etc/ansible/hosts did not meet host_list requirements, check plugin documentation if this is unexpected
/etc/ansible/hosts did not meet script requirements, check plugin documentation if this is unexpected
Parsed /etc/ansible/hosts inventory source with ini plugin
ERROR! A malformed block was encountered while loading tasks

The error appears to have been in '/etc/ansible/scripts/test2.yml': line 2, column 4, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
-  hosts: [ec2-instance]

首先你需要修复你的纯净yaml。

您需要注意与全局任务相关的选项，或者是特定模块的参数：它们应该正确缩进以反映其正确的范围。

您需要确保阅读有关要使用的模块的文档。例如，cli_command确实直接接受字符串，但需要显式command选项，可能还有其他选项。它不会接受列表，因此必须循环其他命令。

最后，您应该检查一些异常情况：

  • 您正在将单个远程主机作为游戏目标（没问题），但列出本地连接。如果这确实是远程主机，则无法正常工作，因为您需要通过 ssh 进入它。
  • 您正在使用（我认为是）任务选项save_when。我认为我理解它错误地位于文件末尾，应该与cli_command模块调用一起使用。同时，它没有列为该模块的参数（但它是其他相关的一部分思科 ios 模块

此时，我不太明白你到底想做什么，所以我只能用我认为正确的方法来修改你的剧本，这样你就可以尝试继续前进。
