对字典的一环

Question

我试图绕过字典，我提到了以下线程，但它一直在失败中：

如何在Ansible中循环浏览此字典？

以下是我的播放书：

- hosts: server_hosts
  tasks:
    - name: Include dictionary data
      include_vars:
        file:  vars/input_vars.yaml
    - name: Show info field from data.yml
      debug:
        msg: "Id: {{ input_data[item]['version'] }} - info: {{ input_data[item]['name'] }}"
      with_items: "{{ input_data.keys() }}"

以下是我的字典vars/input_vars.yaml文件：

input_data:
   item_1:
     name: "test1"
     version: "18.3"
   item_2:
     name: "test2"
     version: "18.3"
   item_3:
     name: "test3"
     version: "18.3"

当我执行剧本时，它失败了以下错误：

fatal: [192.168.16.120]: FAILED! => {
    "ansible_facts": {},
    "ansible_included_var_files": [],
    "changed": false,
    "message": "Syntax Error while loading YAML.n  mapping values are not allowed herennThe error appears to have been in '/git_projects/base/vars/input_vars.yaml': line 2, column 12, but maynbe elsewhere in the file depending on the exact syntax problem.nnThe offending line appears to be:nn----n input_data:n           ^ heren"
}

我已经对其进行了测试，并且可以从input_vars.yaml

中删除了额外的新线

➜  ~  cat input_vars.yaml 
input_data:
   item_1:
     name: "test1"
     version: "18.3"
   item_2:
     name: "test2"
     version: "18.3"
   item_3:
     name: "test3"
     version: "18.3"
➜  ~  cat example.yml 
---
- hosts: localhost
  tasks:
    - name: Include dictionary data
      include_vars:
        file: input_vars.yaml
    - name: Show info field from data.yml
      debug:
        msg: "Id: {{ input_data[item]['version'] }} - info: {{ input_data[item]['name'] }}"
      with_items: "{{ input_data.keys() }}"

输出

➜  ~  ansible-playbook example.yml
