本文档详细介绍了如何从各大云服务商（谷歌云、阿里云、AWS和腾讯云）获取实例的元数据信息，包括CPU平台、内网和外网IP地址、实例ID、区域、镜像ID等关键信息。通过指定的HTTP请求，开发者可以轻松获取到这些数据，以进行自动化配置或监控。

注意必须在云厂商的实例上运行

谷歌云

必须加-H “Metadata-Flavor: Google”
例如：
curl -s http://metadata.google.internal/computeMetadata/v1/instance/cpu-platform -H “Metadata-Flavor: Google”

虚拟机认元数据
https://cloud.google.com/compute/docs/metadata/default-metadata-values?hl=zh_cn
外网ip地址

curl -sH  "Metadata-Flavor: Google" http://metadata/computeMetadata/v1/instance/network-interfaces/0/access-configs/0/external-ip

curl -s http://metadata.google.internal/computeMetadata/v1/instance/ -H "Metadata-Flavor: Google"
