从 EC2 实例中查找区域 [英] Find region from within an EC2 instance

问题描述

有没有办法从实例内部查找实例所在的区域?

Is there a way to look up the region of an instance from within the instance?

我正在寻找类似于查找实例 ID.

推荐答案

那个 URL (http://169.254.169.254/latest/dynamic/instance-identity/document) 似乎不再起作用.当我尝试使用它时，我得到了 404.我有以下似乎有效的代码:

That URL (http://169.254.169.254/latest/dynamic/instance-identity/document) doesn't appear to work anymore. I get a 404 when I tried to use it. I have the following code which seems to work though:

EC2_AVAIL_ZONE=`curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone`
EC2_REGION="`echo "$EC2_AVAIL_ZONE" | sed 's/[a-z]$//'`"

希望这会有所帮助.
