本 Module 用于在阿里云创建一个[应用型负载均衡(ALB)](https://help.aliyun.com/document_detail/250240.html), 并为其绑定Http监听.
5+
6+
本 Module 支持创建以下资源:
7+
8+
* [应用型负载均衡(Alb_Load_Balancer)](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/alb_load_balancer)
9+
* [应用型负载均衡服务器分组(Alb_Server_Group)](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/alb_server_group)
10+
* [应用型负载均衡访问控制权限(Alb_Acl)](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/alb_acl)
11+
* [应用型负载均衡监听(Alb_Listener)](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/alb_listener)
