錯誤“必須將任務中的變數指定為字典或字典串列”

TASK [Create Multiple Users : Create multiple users] ***************************
fatal: [10.12.201.20]: FAILED! => {"reason": "Vars in a Task must be specified as a dictionary, or a list of dictionaries\n\nThe error appears to be in '/runner/project/Windows AD/roles/Create Multiple Users/tasks/Create_multiple_users.yml': line 14, column 9, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n      - \"{{ item.groups }}\"\n  vars: data_list\n        ^ here\n"}

這是我的劇本：

---
- name: Read Users 
  hosts: localhost
  vars:
    data_list: []
  tasks:
  - read_csv:
      path: user.csv
      key: name  
      fieldnames: name,firstname,surname,displayName,groups
      delimiter: ','
    register: userdata


  - name: Extract the list
    set_fact:
      data_list: "{{ data_list   [{ 'name': item.value.name, 'firstname': item.value.firstname, 'surname': item.value.surname, 'displayName': item.value.displayName, 'groups': item.value.groups }] }}"
    loop: "{{ userdata.dict|dict2items }}"


- name: Create multiple Windows AD user accounts
  hosts: "{{ hostname }}"
  gather_facts: false
  any_errors_fatal: false
  become: yes
  become_method: runas
  become_user: admin
  roles:
    - { role: Create Multiple Users }


- name: Create users
  community.windows.win_domain_user:
    name: "{{ item.name }}"
    firstname: "{{ item.firstname }}"
    surname: "{{ item.surname }}"
    attributes:
      displayName: "{{ item.firstname   ' '   item.surname }}"
    groups:
      - "{{ item.groups }}"
  vars: data_list 
  with_items: 
    - "{{ data_list }}"

我應該寫什么正確的變數？

uj5u.com熱心網友回復：

這是導致您的任務錯誤的行

    vars: data_list

如您的錯誤訊息中所述，該vars部分應如下所示：

    vars:
      var1: value1
      var2: value2

但這不是您上面腳本中的唯一問題。您正在單獨播放中收集 csv 資料，localhost并將該資訊設定為變數中的事實data_list。當您的第一次游戲結束時，該 var 將僅從localhost目標中獲知。如果您想在針對其他主機的第二次播放中重用它，則必須從hostvars 魔術變數中獲取該 var

{{ hostvars.localhost.data_list }}

這不是這里最好的方法，因為您可以輕松地將您的劇本縮短為單一劇本。這里的技巧是將您的 csv 收集任務委托給 localhost 并進行設定run_once: true，以便注冊的 var 僅計算一次并分發給具有相同值的所有主機。您還可以洗掉基本上將其復制key: value到新變數的集合事實。

這是一個（未經測驗的）示例劇本，向您展示方式：

---
- name: Create multiple Windows AD user accounts from CSV
  hosts: "{{ hostname }}"
  gather_facts: false

  tasks:
    - name: read csv from localhost (single run same registered var for all hosts)
      read_csv:
        path: user.csv
        key: name  
        fieldnames: name,firstname,surname,displayName,groups
        delimiter: ','
      register: userdata
      run_once: true
      delegate_to: localhost

    - name: Create users
      community.windows.win_domain_user:
        name: "{{ item.name }}"
        firstname: "{{ item.firstname }}"
        surname: "{{ item.surname }}"
        attributes:
          displayName: "{{ item.firstname   ' '   item.surname }}"
        groups:
          - "{{ item.groups }}"
      # This will work on any number of hosts as `userdata`
      # now has the same value for each hosts inside this play.
      # we just have to extract the values from each keys from
      # `userdata` and loop on that list
      loop: "{{ userdata.dict | dict2items | map(attribute='value') }}"
