【问题描述】：

我的 ansible playbook 中有一个名为“inf_list_tmp”的列表，它看起来像：

{
"changed": false,
"ansible_facts": {
    "inf_list_tmp": [
        [],
        [],
        [
            "[dataLoaderJobTaskExecutor-7] - 02/23/2021 07:23:30 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables"
        ],
        [],
        [
            "[dataLoaderJobTaskExecutor-5] - 02/23/2021 07:23:33 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables"
        ],
        [],
        [
            "[dataLoaderJobTaskExecutor-8] - 02/23/2021 07:40:49 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables"
        ],
        [
            "[dataLoaderJobTaskExecutor-1] - 02/23/2021 07:41:21 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables "
        ]
    ]
},
"_ansible_no_log": false

}

现在我想用字符串 'STARTED JOB' 替换上面列表中的空索引

预期输出：

"inf_list_tmp": [
        [STARTED JOB],
        [STARTED JOB],
        [
            "[dataLoaderJobTaskExecutor-7] - 02/23/2021 07:23:30 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables"
        ],
        [STARTED JOB],
        [
            "[dataLoaderJobTaskExecutor-5] - 02/23/2021 07:23:33 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables"
        ],
        [STARTED JOB],
        [
            "[dataLoaderJobTaskExecutor-8] - 02/23/2021 07:40:49 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables"
        ],
        [
            "[dataLoaderJobTaskExecutor-1] - 02/23/2021 07:41:21 ES30CLIENT21  [EventHelperServiceImpl] INFO: Sending event notification [STARTED JOB] for tenant [ES30CLIENT21] with variables "
        ]
    ]

下面是我的代码，但它没有给我预期的输出：

- set_fact: my_list="{{ item.replace(item, 'STARTED JOB') if item|length == 0 else item }}"
  with_items: "{{ inf_list_tmp }}"

有没有办法在 Ansible 剧本中实现这一目标？提前致谢！

【解决方案1】：

让我们简化数据，例如

inf_list_tmp: [[], [], [a], [], [b], [], [c], [d]]

问：“将上面列表中的空索引替换为字符串'STARTED JOB'”

A：下面的任务

    - set_fact:
        inf_list: "{{ inf_list|default([]) + [_item] }}"
      loop: "{{ inf_list_tmp }}"
      vars:
        _item: "{{ (item|length > 0)|ternary(item,  'STARTED JOB') }}"

给予

  inf_list:
  - STARTED JOB
  - STARTED JOB
  - - a
  - STARTED JOB
  - - b
  - STARTED JOB
  - - c
  - - d
