Juniper 设备上的 Ansible 操作失败并显示 "sftp/scp transfer mechanism failed"

Question

我的剧本：

- name: get junos facts
  hosts: sw
#  connection: local
  gather_facts: no
  roles:
    - juniper.junos

  tasks:

    - name: Retrieve Junos OS version
      junipernetworks.junos.junos_command:
        commands: show version

主机：

[sw]
EX4200-2
EX4200-1

变量：

ansible_network_os: juniper_junos

Ansible 配置

ansible-playbook [core 2.12.1]
  config file = /usr/local/san/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/local/python/python38/lib/python3.8/site-packages/ansible
  ansible collection location = /root/.ansible/collections/ansible_collections
  executable location = /usr/local/python/python38/bin/ansible-playbook
  python version = 3.8.10 (default, Dec 30 2021, 10:44:47) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]
  jinja version = 3.0.3
  libyaml = True

运行剧本的结果

    "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",
    "rc": 0
}

SCP 和 SFTP 似乎有问题。但是我手动执行SCP和SFTP是正常的

我该如何修正这个错误？

Answer 1

我的配置文件错了变量添加行： ansible_connection: ansible.netcommon.network_cli

Answer 2

MODULE FAILURE
error: unknown command: /bin/sh

表示远程节点上没有shell、缺少权限等

正如您已经指出的，要使用来自 Ansible Collection Junipernetworks.Junos, according Junos OS Platform Options 的模块，需要正确配置连接设置。

---
- name: Get Junos facts
  hosts: sw
  gather_facts: false

  vars:

    ansible_network_os: juniper_junos
    ansible_connection: ansible.netcommon.network_cli
  
  roles:

    - juniper.junos

  tasks:

    - name: Retrieve Junos OS version
      junipernetworks.junos.junos_command:
        commands: show version
      regsiter: show_version

另外推荐使用junos_facts到Collect facts from remote devices running Juniper Junos in Example

- name: Collect default set of facts and configuration
  junipernetworks.junos.junos_facts:
    gather_subset: config
