Ansible - 循环结果+ when语句

标签： ansible ansible-playbook

我的目标是遍历cisco交换机上的接口，检查access vlan，然后在设置为＆＃34; 12＆＃34;时更改该vlan。或者生活在12岁以外的其他地方。为此，我将结果保存到＆＃34; int_out＆＃34;：

   - name: check vlan on some interfaces and save to int_out
     ios_command:
      commands: show run int Fa0/{{ item }} | incl switchport access vlan
      provider: "{{ cli }}"
     with_sequence: start=1 end=3 stride=1
     register: int_out

我想循环遍历＆＃34; int_out＆＃34;结果和使用＆＃34;当＆＃34;如下所示的statemant来改变访问vlan：

   - name: change vlan if needed
     ios_config:
      lines: switchport access vlan 1234
      parents: interface Fa0/{{item}}
     when: item.stdout_lines == " switchport access vlan 12"
     with_items: "{{ int_out.results }}"

但比较不起作用：

TASK [change vlan when needed] *************************************************

如果我检查＆＃34; item.stdout_lines＆＃34;的输出看错了：

   - debug: msg= "{{ item.stdout_lines }}"
     with_items: "{{ int_out.results }}"

我不仅得到了stdout_lines，还有更多：

            }, 
            "module_name": "ios_command"
        }, 
        "item": "3", 
        "stdout": [
            " switchport access vlan 12"
        ], 
        "stdout_lines": [
            [
                " switchport access vlan 12"
            ]
        ]
    }, 
    "msg": ""
}

但是当我运行这样的代码时：

- debug: msg="{{int_out.results[1].stdout}}"

我得到了这样的答复：

TASK [debug] *******************************************************************
ok: [192.168.0.33] => {
    "msg": [
        " switchport access vlan 12"
    ]
}

任何想法是什么？我怎样才能实现目标？

1 个答案:

答案 0 :(得分：0)

如果仔细查看int_out.results个元素，您会注意到stdout是一个字符串列表，而stdout_lines是一个列表列表。
我怀疑ios_config模块将列表返回为stdout（而不是command / shell模块中的多行字符串），Ansible的标准结果处理器会将{{1变量到新列表中。

所以你只需要按如下方式调整stdout语句：

when:

访问when: item.stdout[0] == " switchport access vlan 12" 列表的第一个元素。
