python - os_network 的参数列表上的 ansible 抛出错误

Question

我们已经在 ubuntu 14.04 中安装了 ansible 版本 2.1.0。

在使用 os_network 模块时，我们遇到了这个错误。

root@ubuntu:/home/admin-nfv/Nuage_Automation/nuage_vm_creation/playbooks# ansible-playbook create_or_delete_network.yml
 [WARNING]: provided hosts list is empty, only localhost is available


PLAY [Create Network] **********************************************************

ok: [localhost]

TASK [create_network : create or delete network] *******************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: TypeError: create_network() takes at most 4 arguments (7 given)
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "module_stderr": "Traceback (most recent call last):\n  File \"/tmp/ansible_crfy0P/ansible_module_os_network.py\", line 247, in <module>\n    main()\n  File \"/tmp/ansible_crfy0P/ansible_module_os_network.py\", line 226, in main\n    external, provider, project_id)\nTypeError: create_network() takes at most 4 arguments (7 given)\n", "module_stdout": "", "msg": "MODULE FAILURE", "parsed": false}

NO MORE HOSTS LEFT *************************************************************
        to retry, use: --limit @create_or_delete_network.retry

PLAY RECAP *********************************************************************
localhost                  : ok=1    changed=0    unreachable=0    failed=1

-vvv 错误的输出是

An exception occurred during task execution. The full traceback is:
Traceback (most recent call last):
  File "/tmp/ansible_9jY3t3/ansible_module_os_network.py", line 247, in <module>
    main()
  File "/tmp/ansible_9jY3t3/ansible_module_os_network.py", line 226, in main
    external, provider, project_id)
TypeError: create_network() takes at most 4 arguments (7 given)

fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "invocation": {"module_name": "os_network"}, "module_stderr": "Traceback (most recent call last):\n  File \"/tmp/ansible_9jY3t3/ansible_module_os_network.py\", line 247, in <module>\n    main()\n  File \"/tmp/ansible_9jY3t3/ansible_module_os_network.py\", line 226, in main\n    external, provider, project_id)\nTypeError: create_network() takes at most 4 arguments (7 given)\n", "module_stdout": "", "msg": "MODULE FAILURE", "parsed": false}

我们用来创建网络的剧本是

- name: create or delete network
  os_network:
    auth:
      auth_url: "http://1.2.3.4:35357/v2.0"
      username: "admin"
      password: "xxxxxxx"
      project_name: "admin"
    state: "present"
    name: "Test"
    external: true

在另一台机器上，相同的代码可以正常运行，没有任何错误。但不确定环境有什么问题。

Ansible 在 os_network 模块中使用 shade pip 包。该包内的接口(interface)，尤其是围绕 create_network 方法的接口(interface)在最近的版本中发生了变化，新版本的 ansible 现在依赖于新功能。

您应该确保在您的 ansible 主机上使用最新版本，目前是 1.9.0

pip install shade==1.9.0
