Ansible playbook文件选择任务

Question

这可能违反最佳实践，但使用 Ansible 剧本，是否可以从一项任务中获取文件列表，然后向用户提示 select 将其中一个文件传递到变量中？

例如：

Choose file to select:
1. file1.txt
2. file2.txt
3. file3.txt
> 1

剧本理论上会暂停以等待用户输入，然后将生成的文件 selection 传递到一个变量中以在未来的任务中使用。

非常感谢。

使用pause。例如，给定文件

shell> tree files
files
├── file1.txt
├── file2.txt
└── file3.txt

0 directories, 3 files

下面的剧本

shell> cat playbook.yml
- hosts: localhost
  tasks:
    - find:
        path: files
      register: result
    - set_fact:
        my_files: "{{ result.files|map(attribute='path')|list|sort }}"
    - pause:
        prompt: |
          Choose file to select:
          {% for file in my_files %}
          {{ loop.index }} {{ file }}
          {% endfor %}
      register: result
    - debug:
        msg: "selected file: {{ my_files[result.user_input|int - 1] }}"

给出（选择第二文件并输入'2

shell> ansible-playbook playbook.yml 

PLAY [localhost] ****

TASK [find] ****
ok: [localhost]

TASK [set_fact] ****
ok: [localhost]

TASK [pause] ****
[pause]
Choose file to select:
1 files/file1.txt
2 files/file2.txt
3 files/file3.txt
:
ok: [localhost]

TASK [debug] ****
ok: [localhost] => {
    "msg": "selected file: files/file2.txt"
}

PLAY RECAP ****
localhost: ok=4 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
