Ansible内联jinja模板化为列表

我不明白为什么这行不通。 我正在使用jinja动态生成我将传递给vmware_来宾模块的列表，以便我可以在主机或组变量中决定是否要添加其他磁盘。 我正在使用vmware_disk_info模块查找模板磁盘的大小，然后添加我将在组变量中定义的任何其他磁盘。 在我看来，输出的列表不是一个列表

一个例子是：

additional_disks:
  - size_gb: "120"
    datastore: "VSAN_Datastore"

基于以下建议的新代码： 但是，同样的错误是：

  set_fact:
    vm_disks: >-
      {%- set results = [] -%}
      {%- for osdisk in ( template_disk.guest_disk_info | dictsort ) -%}

      {%- set _ = od.update({ "datastore": osdisk[1].backing_datastore }) -%}
      {%- set _ = results.append(od) -%}

这看起来像一个列表，为了验证这一点，我将结果传输到to_json过滤器，它错误地说，这不是一个str，而是一个列表。

因此，它肯定是一个列表。

正如Uttam正确指出的，但没有提供答案，问题是您的

设置事实：

生成字符串，但

磁盘必须是
目录的
列表，从（和）可以看出

有两个原因：第一个原因是ansible仅自动将JSON字符串强制转换为实际的python
list
和
dict
结构，但您使用了带有单引号字符串文本和尾随逗号的python语法，这两种语法都是非法的JSON

第二，绝不能使用文本在jinja中构建丰富的数据结构：它强烈支持这些数据结构，以及来自json的精彩和
|过滤器，以确保输出是合法的json和正确的转义字符

但是我知道这是一大堆单词，所以我相信你能做的最小的改变就是停止使用单引号并保护后面的逗号：

-name:“定义新磁盘结构”
设定事实：
虚拟机磁盘：>-
[
{中磁盘的%（模板_disk.guest _disk |信息| dictsort）%}
{{“if loop.first else”，“}}
{
“大小\ kb”：{{磁盘[1]。容量\单位为\ kb}，
“数据存储”：“{datastore_name}”
