ansible的循环二

with_items 遍历列表中每个元素，包括嵌套列表

with_list 将嵌套列表作为整体元素遍历

with_together 将多个列表中的子列表元素，一起输出，不成对则null补位

示例：

---

• hosts: jack6_1

  remote_user: root

  gather_facts: no

  tasks:

  • debug:

    msg: "{{item}}"

    with_items:

    • [1,2,3]
    • [a,b]
  • debug:

    msg: "{{item}}"

    with_list:

    • [4,5,6]
    • [c,d]
  • debug:

    msg: "{{item}}"

    with_together:

    • [7,8,9]
    • [e,f]

输出结果如下：
