ansible中的Nsupdate模块导致错误

Question

当我尝试运行下面的.yml角色时，我得到了一个关于nsupdate的错误。

我使用的是centos7，机器运行的是bind。

当我使用原始DNS服务器或ansible master进行nsupdate时，我可以更新记录，只有当我使用nsupdate模块时它才不起作用，有什么帮助吗？泰！

tasks/main.yml

这是包含相关代码的部分

- name: Add or modify ansible.example.org A to 192.168.1.1"
  community.general.nsupdate:
    server: "10.0.0.40"
    zone: "ben.com."
    record: "ansible"
    value: "192.168.1.1"
  when: ansible_eth1.ipv4.address == '10.0.0.40'

错误：

问题是它很可能是在主机上错误的接口上运行的，就像@Patrick提到的那样。通过如下方式添加主机组变量修复了该问题：

[DNS_Master:vars]
ansible_python_interpreter=/usr/local/bin/python3.9
