ansible - 循环查找文件并删除它们

Question

我想删除某些包含特定格式的子目录中的文件。但是，我收到了错误

'dict object' has no attribute 'files'.

下面是我的代码。文件模式将为 file_name.file_extension.processID.YYYY-MM-DD@HH:MM:SS~

我的变量

fileToFindInAllSubDirecotry
  - "home/usr/file1"
  - "home/usr/file2"
  - "home/usr/file3/file4"
  - "home/usr/file5"

我的剧本角色

- name: Find file
  find:
    paths: "{{ item }}"
    use_regex: yes
    patterns:
      - '.*\.\d+\.\d{4}-\d{2}-\d{2}@\d{2}:\d{2}:\d{2}~$'
    age: 1d
    recurse: yes
  register: fileToDelete
  loop: "{{ fileToFindInAllSubDirecotry }}"
  
- name: Delete file
  file:
    path: "{{ item.path }}"
    state: absent
  loop: "{{ fileToDelete.files }}"

这是示例文件和目录

home
   |-------usr
             |-------file1
                         |-------configFile.xml
             |-------file2
                         |-------propertiesFile.txt.2012.2020-07-13@23:08:10~
             |-------file3
                         |-------file4
                                     |-------content.yml.2012.2020-04-04@23:08:10~                       
             |-------file5
                         |-------configFile.xml.2012.2020-03-05@13:08:10~

发生这种情况是因为您正在填充 find有一个循环，所以你最终得到的结果将是一个有列表或 results 的字典。 .

类似于:

ok: [localhost] => {
    "msg": {
        "changed": false,
        "msg": "All items completed",
        "results": [
            {
                ...
                "files": [ ... ],
                ...
                "item": "/home/usr/file1",
                ...
            },
            {
                ...
                "files": [ ... ],
                ...
                "item": "/home/usr/file2",
                ...
            },
            ...
        ]
    }
}

有两种方法可以解决这个问题:

1. 最好的一个，因为正如文档所指出的那样， paths 模块 find 的参数可以接受路径列表，只需将整个 fileToFindInAllSubDirecotry 传递给它即可变量而不是使用循环，这样您的删除就可以按原样进行:

   - name: Find file
     find:
       paths: "{{ fileToFindInAllSubDirecotry }}"
       use_regex: yes
       patterns:
         - '.*\.\d+\.\d{4}-\d{2}-\d{2}@\d{2}:\d{2}:\d{2}~$'
       age: 1d
       recurse: yes
     register: fileToDelete
   
   - name: Delete file
     file:
       path: "{{ item.path }}"
       state: absent
     loop: "{{ fileToDelete.files }}"
   

2. 使用 json_query 获取 result[*].files然后 flatten 列表的结果列表

   - name: Find file
     find:
       paths: "{{ item }}"
       use_regex: yes
       patterns:
         - '.*\.\d+\.\d{4}-\d{2}-\d{2}@\d{2}:\d{2}:\d{2}~$'
       age: 1d
       recurse: yes
     register: fileToDelete
     loop: "{{ fileToFindInAllSubDirecotry }}"
   
   - name: Delete file
     file:
       path: "{{ item.path }}"
       state: absent
     loop: "{{ fileToDelete | json_query('results[*].files') | flatten }}"
