二、常用接口
1、网卡对应的网络相关
#获取网卡mac地址 MAC=`curl -s http://100.100.100.200/latest/meta-data/network/interfaces/macs/ #网卡对应的子网掩码 curl http://100.100.100.200/latest/meta-data/network/interfaces/macs/${MAC}/netmask #网卡主私IP地址 curl http://100.100.100.200/latest/meta-data/network/interfaces/macs/${MAC}/primary-ip-address #网卡的网关地址 curl http://100.100.100.200/latest/meta-data/network/interfaces/macs/${MAC}/gateway
2、vpc相关
#使用的vpc实例id curl http://100.100.100.200/latest/meta-data/vpc-id #vpc实例的网段 curl http://100.100.100.200/latest/meta-data/vpc-cidr-block #使用的交换机实例id curl http://100.100.100.200/latest/meta-data/vswitch-id #交换机网段 curl http://100.100.100.200/latest/meta-data/vpc-cidr-block
3、ecs实例相关
#实例规格 curl http://100.100.100.200/latest/meta-data/instance/instance-type #实例创建时间(+8小时) curl http://100.100.100.200/latest/meta-data/instance/last-host-landing-time #实例规格的出方向内网最大带宽。单位：Kbit/s。 curl http://100.100.100.200/latest/meta-data/instance/max-netbw-egress #公网IP curl http://100.100.100.200/latest/meta-data/eipv4 #地区信息等 curl http://100.100.100.200/latest/meta-data/region-id #实例id curl http://100.100.100.200/latest/meta-data/instance-id
4、直接获取ip、mac、实例id、地区等信息
curl http://100.100.100.200/latest/dynamic/instance-identity/document
