Ansible Juniper CLI命令.超时错误? [英] Ansible, Juniper CLI commands. Timeout Error?

问题描述

我正在尝试将我在Python中制作的自动化脚本转移到ansible(公司要求)，而我以前从未使用过ansible.我已经尝试过"wait_for:"，但是我也没有使它起作用.在脚本中，我可以设置dev.timeout = None或任何我需要的值.我发现很难弄清楚在哪里可以做到这一点.我尝试在"ansible.cfg"文件中设置超时.但这不起作用.我可以执行简单的命令，例如:

I am trying to transfer an automation script I made in Python, to ansible (company request), and I have NEVER worked with ansible before. I have tried the "wait_for:", but I have not gotten that to work either. In the script, I could set dev.timeout=None or whatever I needed. I am finding it hard to figure out where I can do this in ansible. I have tried setting the timeout in the "ansible.cfg" file. But that doesnt work. I can do simple commands, like:

cli =显示版本"，或 cli =显示系统固件".

cli="show version", or cli="show system firmware".

以下是我的剧本:

    - hosts: local
  roles:
  - Juniper.junos
  connection: local
  gather_facts: no

  tasks:
  - junos_cli:
      host={{ inventory_hostname }}
      user=root
      passwd=Hardware1
      cli="request system snapshot slice alternate"
      dest="{{ inventory_hostname }}.txt"

运行该命令后，大约120秒后，出现以下错误:

After I run that, around 120 seconds later, I get the following error:

fatal: [192.168.2.254]: FAILED! => {"changed": false, "failed": true, "module_stderr": "/usr/local/lib/python2.7/dist-packages/jnpr/junos/device.py:652: RuntimeWarning: CLI command is for debug use only!\n  warnings.warn(\"CLI command is for debug use only!\", RuntimeWarning)\nTraceback (most recent call last):\n  File \"/home/pkb/.ansible/tmp/ansible-tmp-1457428640.58-63826456311723/junos_cli\", line 2140, in <module>\n    main()\n  File \"/home/pkb/.ansible/tmp/ansible-tmp-1457428640.58-63826456311723/junos_cli\", line 177, in main\n    dev.close()\n  File \"/usr/local/lib/python2.7/dist-packages/jnpr/junos/device.py\", line 504, in close\n    self._conn.close_session()\n  File \"/usr/local/lib/python2.7/dist-packages/ncclient/manager.py\", line 158, in wrapper\n    return self.execute(op_cls, *args, **kwds)\n  File \"/usr/local/lib/python2.7/dist-packages/ncclient/manager.py\", line 228, in execute\n    raise_mode=self._raise_mode).request(*args, **kwds)\n  File \"/usr/local/lib/python2.7/dist-packages/ncclient/operations/session.py\", line 28, in request\n    return self._request(new_ele(\"close-session\"))\n  File \"/usr/local/lib/python2.7/dist-packages/ncclient/operations/rpc.py\", line 342, in _request\n    raise TimeoutExpiredError('ncclient timed out while waiting for an rpc reply.')\nncclient.operations.errors.TimeoutExpiredError: ncclient timed out while waiting for an rpc reply.\n", "module_stdout": "", "msg": "MODULE FAILURE", "parsed": false}

我认为这是超时，我可能是错的.但是，如此简单的任务使我望而却步.

I think it is the timeout, I could be wrong. But it is doing my head in that such a simple task is eluding me.

推荐答案

好的，我设法解决了这个问题.

Okay, I managed to fix the problem.

执行CLI的Ansible模块(junos_cli)不支持超时.为此，我进入了:

The module for Ansible that does the CLI (junos_cli) doesn't support timeout. I therefor went in to:

/etc/ansible/roles/Juniper.junos/library/junos_cli

在下面一行:

dev = Device(args['host'], user=args['user'], password=args['passwd'],
                     port=args['port'], gather_facts=False).open()

我添加了:

dev.timeout=None

这将计时器设置为无穷大，因此在进行请求系统快照切片备用"时，我有时间进行格式化.

This sets the timer to infinity, so I have time for the formatting when doing "request system snapshot slice alternate".

希望这可以帮助其他人通过ansible自动化对junos cli做一些事情.

Hope this helps anyone else doing something with the junos cli through ansible automation.
