ansible的循环二

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：

[root@jack7-1 work]# ansible-playbook item_list.yml
