powershell - Ansible Playbook - 从 Windows 远程机器获取文件

Question

我有一个剧本可以做 3 件事 -

1. 查找主机中的目录列表
2. 根据找到的目录找到文件列表
3. 将文件提取到我的本地服务器。

我使用 win_shell 模块来查找目录和文件，调试结果显示它可以正确找到它们。 但是，当我使用 fetch 模块时，它指出我注册到循环中的文件是目录 -

---

- hosts: Host
  gather_facts: no
  tasks:

  - name: Find DIR Directories
    win_shell: Get-ChildItem {{ partition }}:\Main\Production\App\    -Recurse -Directory "DIR" -Exclude "NotInUse" |% {Write-Host $_.FullName}
    register: dataDirs
  - debug:
      var: dataDirs

  - name: Find Each DIR Files
    win_shell: Get-ChildItem {{ item }} *.csv -Recurse |% {Write-Host $_.FullName}
    with_items: "{{ dataDirs.stdout_lines }}"
    register: dataFiles
  - debug:
     var: dataFiles

  - name: Fetch All Files
    fetch: src= "{{ item.stdout_lines }}" dest=/local/DIRFiles/
    with_items: "{{ dataFiles.results }}"
...

结果是——

MSG:

**remote file is a directory, fetch cannot work on directories**

PLAY RECAP *********************************************************************************************************************************************************************************************
Host                      : ok=4    changed=2    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0

我厌倦了将第二个 win_shell 更改为 win_find，它一直告诉我这些文件是目录。

我做错了什么？ 谢谢。

fetch documentation说明 src parameter是 string 类型的值，表示单个文件的路径。您正在传递一个列表。

您要做的是在每个 results 中遍历 stdout_lines 中的每个文件。

实现此目的的一种方法:

  - name: Fetch All Files
    fetch:
      src: "{{ item.1 }}"
      dest: /local/DIRFiles/
    with_subelements:
      - "{{ dataFiles.results }}"
      - stdout_lines
