AWS Local Zone是否支持EFS挂载目标？us-east-1-atl-1a部署问题

问题描述 #

尝试使用Terraform在us-east-1-atl-1a AWS Local Zone中创建EFS挂载目标时失败，手动通过AWS控制台创建也无法选择该可用区，AWS Local Zone官方信息页面未提及EFS相关支持说明。

Terraform返回错误如下：

│ Error: UnsupportedAvailabilityZone: Mount targets are not supported in subnet's availability zone.
│ {
│   RespMetadata: {
│     StatusCode: 400,
│     RequestID: "23192f37-77e6-421b-b623-4a2b6dfb6217"
│   },
│   ErrorCode: "UnsupportedAvailabilityZone",
│   Message_: "Mount targets are not supported in subnet's availability zone."
│ }
│

结论与说明 #

1. us-east-1-atl-1a Local Zone不支持EFS挂载目标

   • Terraform返回的UnsupportedAvailabilityZone错误是AWS服务层面的明确限制，直接说明该区域无法创建EFS挂载目标。
   • 控制台无法选择该区域的操作，进一步验证了该Local Zone未开放EFS挂载目标的支持。

2. 关于EKS集群创建错误
   这是该Local Zone的容量不足问题，和EFS支持性无关，AWS已给出解决方案：选择us-east-1a/us-east-1b/us-east-1c/us-east-1d/us-east-1f这些标准可用区创建EKS集群。
