AWS Public IP在运行实例中

Question

When i do ifconfig in my EC2 instance I get private IP. But adding to sites-available in my apache I need public ip.

Is there any way i can get my public IP in my running instance.

Answer 1

There is a "magic IP" on amazon EC2 instaces which you can curl for metadata about your instance.

To get the public IP of a current instance you can do:

curl http://169.254.169.254/latest/meta-data/public-ipv4
