EdgeOS Ansible 问题

尝试使用 edgeos_commandmodule 运行剧本时收到以下信息：

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ansible.module_utils.connection.ConnectionError: ssh connection failed: ssh connect failed: Failed to resolve hostname inventory_hostname (Name or service not known)
fatal: [ADM-TEST]: FAILED! => {
  "changed": false,
  "module_stderr": "...",
  "module_stdout": "",
  "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",
  "rc": 1
}

其中module_stderr包含：

Traceback (most recent call last):

这很奇怪，因为我可以顺利地通过 ssh 进入目标设备。我从一个简单的剧本开始，并计划在测试完 edgeos 模块后在此基础上进行构建

以下是剧本：

- name: Update External ERX with latest firmware
  hosts: externaledgerouters
  remote_user: BudAdmin
  tasks:
    - name: Update ERX Firmwae
      community.network.edgeos_command:
       commands: show system image

在我的 ansible.cfg 中，我有指向 hosts 文件的清单

以下是我在 hosts 文件中格式化库存的方法：

externaledgerouters:
 hosts:
  ADM-TEST:
   ansible_host: (ipv4 public IP)

在同一个 hosts 文件底部定义变量：

edgerouters:
 vars:
  ansible_user: (user)
  ansible_port: (port)
  ansible_pass: (password)
  ansible_connection: network_cli
  ansible_network_os: edgeos
 children:
  externaledgerouters:

我尝试了很多方法来实现它，但都失败了。任何帮助我都感激不尽。

答案1

过了一段时间，我终于搞清楚了。.ssh/known_hosts 文件和运行边缘路由器的剧本存在一些问题

我为两个测试主机重新生成了密钥 ssh-keygen R HOSTNAME - 还必须向本地 known_hosts 文件添加写入权限 chmod +w ~/.ssh/known_hosts - 然后我就可以毫无问题地运行剧本了
