Variables Stat.exists与ansible中的变量列表一起存在

Variables Stat.exists与ansible中的变量列表一起存在,variables,ansible,jinja2,ansible-playbook,Variables,Ansible,Jinja2,Ansible Playbook,我在Ansible中使用口述检查现有文件时遇到问题 tasks: - name: Checking existing file id stat: path=/tmp/{{ item.id }}.conf with_items: "{{ file_vars }}" register: check_file_id - name: Checking existing file name stat: path=/tmp/{{ item.name }}.con

我在Ansible中使用口述检查现有文件时遇到问题

  tasks:
  - name: Checking existing file id
    stat: path=/tmp/{{ item.id }}.conf
    with_items: "{{ file_vars }}"
    register: check_file_id

  - name: Checking existing file name
    stat: path=/tmp/{{ item.name }}.conf
    with_items: "{{ file_vars }}"
    register: check_file_name

  - name: Checking file exists
    debug: msg='File_id exists'
    when: check_file_id.stat.exists == True

  - name: Checking file name exists
    debug: msg='File name exists'
    when: check_file_name.stat.exists == True

  vars:
    file_vars:
      - { id: 1, name: one }
      - { id: 2, name: two }
然后,如果我试图运行playbook,我会得到错误:

FAILED! => {"failed": true, "msg": "The conditional check 'check_file_id.stat.exists == True' failed. The error was: error while evaluating conditional (check_file_id.stat.exists == True): 'dict' object has no attribute 'stat'\n\n
我已尝试调试它:

-debug:var=check\u file\u id
得到:

我错在哪里? 是否可以将
stat.exists
与变量列表一起使用


谢谢你的回答

问题是您正在循环中注册
检查文件\u id
。您需要阅读,其中讨论了这样做的含义。变量有一个
results
键,其中包含循环每次迭代的结果。您可以在
debug
输出中看到这一点

在后续任务中,您应该迭代
检查文件\u id.results
,而不是
文件\u vars
,如下所示:

- hosts: localhost
  gather_facts: false
  vars:
    file_vars:
      - {id: 1, name: foo}
      - {id: 2, name: bar}
  tasks:
    - name: Checking existing file id
      stat:
        path: ./files/{{ item.id }}.conf
      with_items: "{{ file_vars }}"
      register: check_file_id

    - name: Checking existing file name
      stat:
        path: ./files/{{ item.name }}.conf
      with_items: "{{ file_vars }}"
      register: check_file_name

    - debug:
        msg: 'file id {{item.item.id}} (name {{item.item.name}}) exists'
      with_items: "{{ check_file_id.results }}"
      when: item.stat.exists

    - debug:
        msg: 'file name {{item.item.name}} (id {{item.item.id}}) exists'
      with_items: "{{ check_file_name.results }}"
      when: item.stat.exists
- hosts: localhost
  gather_facts: false
  vars:
    file_vars:
      - {id: 1, name: foo}
      - {id: 2, name: bar}
  tasks:
    - name: Checking existing file id
      stat:
        path: ./files/{{ item.id }}.conf
      with_items: "{{ file_vars }}"
      register: check_file_id

    - name: Checking existing file name
      stat:
        path: ./files/{{ item.name }}.conf
      with_items: "{{ file_vars }}"
      register: check_file_name

    - debug:
        msg: 'file id {{item.item.id}} (name {{item.item.name}}) exists'
      with_items: "{{ check_file_id.results }}"
      when: item.stat.exists

    - debug:
        msg: 'file name {{item.item.name}} (id {{item.item.id}}) exists'
      with_items: "{{ check_file_name.results }}"
      when: item.stat.exists
