查询可用区列表
功能介绍
返回租户创建LB时可使用的可用区集合列表情况。
-
默认情况下,会返回一个可用区集合。
在(如创建LB)设置可用区时,填写的可用区必须包含在可用区集合中、为这个可用区集合的子集。
-
特殊场景下,部分客户要求负载均衡只能创建在指定可用区集合中,此时会返回客户定制的可用区集合。
返回可用区集合可能为一个也可能为多个,比如列表有两个可用区集合[az1,az2],[az2,az3]。
在创建负载均衡器时,可以选择创建在多个可用区,但所选的多个可用区必须同属于其中一个可用区集合,
如可以选az2和az3,但不能选择az1和az3。你可以选择多个可用区,只要这些可用区在一个子集中
