with_nested 接纳笛卡尔乘积方式,将多个嵌套列表中的元素交织组合

示例:
建立多个目录及子目录
mkdir -p /testdir/{a,b,c}/{1,2}

ansible剧本如下:


  • hosts: jack6_1
    remote_user: root
    gather_facts: no
    tasks:
    • file:
      path: "/testdir"
      state: directory
    • file:
      path: "/testdir/{{item.0}}/{{item.1}}"
      state: directory
      with_nested:
      • [a,b,c]
      • [t1,t2]

执行效果如下:
[root@jack7-1 work]# ansible jack6_1 -m shell -a "tree /testdir"
jack6_1 | CHANGED | rc=0 >>
