使用 Ansible 将列表转换为字典中的值

Question

我正在尝试使用来自 Linux 主机的 Ansible gather_facts 数据作为输入：

    "ansible_fibre_channel_wwn": [
        "1000e0071bd4d0ed",
        "10009440c90f9d85",
        "1000e0071bce95f3",
        "1000e0071bce95f2",
        "1000e0071bd4d0ec",
        "10009440c90f9d84"
    ],

并希望使用上述列表项为新“wwpn”键的字典值创建字典：

        fc_initiators: [
            {wwpn: '10:00:e0:07:1b:d4:d0:ed'}, 
            {wwpn: '10:00:94:40:c9:0f:9d:85'}, 
            {wwpn: '10:00:e0:07:1b:ce:95:f3'}, 
            {wwpn: '10:00:e0:07:1b:ce:95:f2'}, 
            {wwpn: '10:00:e0:07:1b:d4:d0:ec'}, 
            {wwpn: '10:00:94:40:c9:0f:9d:84'}
        ]

这个正则表达式似乎足以将初始列表项转换为殖民 WWPN：

"{{ ansible_fibre_channel_wwn | 
map('regex_replace', '^(..)(..)(..)(..)(..)(..)(..)(..)$', '\\1:\\2:\\3:\\4:\\5:\\6:\\7:\\8')|list }}"

我不确定从哪里开始列表->字典转换。 非常感谢任何帮助。

谢谢！

Answer 1

首先“殖民”项目，例如

    - set_fact:
        wwn_colonized: "{{ wwn_colonized|default([]) +
                           [item|map('join')|join(':')] }}"
      loop: "{{ ansible_fibre_channel_wwn|map('batch', 2)|map('list')|list }}"

给予

  wwn_colonized:
  - 10:00:e0:07:1b:d4:d0:ed
  - 10:00:94:40:c9:0f:9d:85
  - 10:00:e0:07:1b:ce:95:f3
  - 10:00:e0:07:1b:ce:95:f2
  - 10:00:e0:07:1b:d4:d0:ec
  - 10:00:94:40:c9:0f:9d:84

然后下面的任务创建字典列表

    - set_fact:
        fc_initiators: "{{ wwn_colonized|
                           map('regex_replace', '^(.*)$', '{wwpn: \\1}')|
                           map('from_yaml')|
                           list }}"

给予

  fc_initiators:
  - wwpn: 10:00:e0:07:1b:d4:d0:ed
  - wwpn: 10:00:94:40:c9:0f:9d:85
  - wwpn: 10:00:e0:07:1b:ce:95:f3
  - wwpn: 10:00:e0:07:1b:ce:95:f2
  - wwpn: 10:00:e0:07:1b:d4:d0:ec
  - wwpn: 10:00:94:40:c9:0f:9d:84

或者，JSON 中的相同数据

  fc_initiators|to_nice_json: |-
    [
        {
            "wwpn": "10:00:e0:07:1b:d4:d0:ed"
        },
        {
            "wwpn": "10:00:94:40:c9:0f:9d:85"
        },
        {
            "wwpn": "10:00:e0:07:1b:ce:95:f3"
        },
        {
            "wwpn": "10:00:e0:07:1b:ce:95:f2"
        },
        {
            "wwpn": "10:00:e0:07:1b:d4:d0:ec"
        },
        {
            "wwpn": "10:00:94:40:c9:0f:9d:84"
        }
    ]
