Pod Rack Details Using Availability Zone in AWS
问题
我正在尝试使用AWS的Java API自动映射可用性区域到相应的机架ID。是否有方法可以做到这一点？基本上，给定一个可用性区域，比如："us-east-1a"，该库应返回"use1-az1"作为机架ID。
英文:
I'm trying to automate a mapping between availability zone to its corresponding rackID in AWS using their Java API.
Is there a way to do this?
Basically, given an availability zone, say: "us-east-1a", the library should return "use1-az1" as the rack ID.

节点控制器不会为节点标记与放置组关联的分区或其所在的机架。如果您想获取该信息，您需要将标签添加到节点，例如 GroupName=GroupA，PartitionID=5，或者从您的应用程序中查询 EC2 API。请注意，部署到放置组的实例不会自动打标签。有关更多信息，请参阅 https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html。
英文:
The node controller does not label the node with the partition associated with a placement group or the rack that it is in. If you want to get that information, you'll either need to add labels to the node, e.g. GroupName=GroupA,PartitionID=5 or query the EC2 API from your application. Be aware that instances deployed into a placement group are not automatically tagged. See https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html for additional information.
