平台

安装

ansible-galaxy install darexsu.firewalld --force

行为

替换或合并字典（在 ansible.cfg 中使用 "hash_behaviour=replace"）：

# 替换             # 合并
---                   ---
  vars:                 vars:
    dict:                 merge:
      a: "value"            dict: 
      b: "value"              a: "value" 
                              b: "value"

# 合并是如何工作的？
你的变量 [host_vars]  -->  默认变量 [当前角色] --> 默认变量 [包含角色]
  
  dict:          dict:              dict:
    a: "1" -->     a: "1"    -->      a: "1"
                   b: "2"    -->      b: "2"
                                      c: "3"
