迭代未知数量的自定义 Ansible 事实

Question

我编写了一些自定义事实，我将其作为任务中模块的值引用。当我有 1 个自定义事实时，运行任务没有问题，但问题是，当我有未知数量的事实并且我想为每个事实运行任务时，我该怎么办？我有以下事实：

"ansible_facts": {
    "ansible_local": {
        "facts": {
            "finance": {
                "files": {
                    "file1": {
                        "dest": "/tmp/dir1",
                        "path": "/etc/finance/file1"
                    },
                    "file2": {
                        "dest": "/tmp/dir2",
                        "path": "/etc/finance/file2"
                    }
                }
            }
        }
    }
},

这是我的任务的代码：

- name: Copy files
  copy:
    src: "/tmp/file1/{{ ansible_local.facts.finance.files.file1.path }}"
    dest: "/ghostcache/{{ ansible_local.facts.finance.files.file1.dest }}/"
    remote_src: yes

鉴于文件下的项目数量未知，我该如何迭代“文件”下的所有项目并获取两个值（目标和路径）并将它们作为值放入复制模块？我可能只有 1 个，即 file1 或者可能有 file1...fileN。

谢谢 ！

这是您正在寻找的代码吗？

- hosts: localhost

              dest: "/tmp/dir2"                                                              
              path: "/etc/finance/file2"                                               
  tasks:                                                                                     
    - debug:                                                                                 
        msg: "src: {{ item.value.path}} dest: {{ item.value.dest }}"                         
      with_dict: "{{ facts.finance.files }}"
