如何知道机器是否是Google Compute Engine实例 [英] How to know if a machine is an Google Compute Engine instance

问题描述

是否可以从命令行shell知道我当前是否在Google Compute Engine计算机上或其他地方(开发计算机)上?

Is there a way to know from a command line shell if I am currently on a Google Compute Engine machine or somewhere else (development machine)?

推荐答案

每个元数据文档:

您可以使用元数据服务器轻松检测您的应用程序或脚本是否在Compute Engine实例中运行.当您向服务器发出请求时，来自元数据服务器的任何响应都将包含Metadata-Flavor: Google标头.您可以查找此标头，以可靠地检测您是否正在Compute Engine中运行.

You can easily detect if your applications or scripts are running within a Compute Engine instance by using the metadata server. When you make a request to the server, any response from the metadata server will contain the Metadata-Flavor: Google header. You can look for this header to reliably detect if you are running in Compute Engine.

例如，以下curl请求返回Metadata-Flavor: Google标头，表明该请求是在Compute Engine实例内进行的.

For example, the following curl request returns a Metadata-Flavor: Google header, indicating that the request is being made from within a Compute Engine instance.

me@my-inst:~$ curl metadata.google.internal -i
HTTP/1.1 200 OK
