Retrieve dynamic data

To retrieve dynamic data from within a running instance, use the following URI.

http://169.254.169.254/latest/dynamic/
Note

The examples in this section use the IPv4 address of the instance metadata service: 169.254.169.254. If you are retrieving instance metadata for EC2 instances over the IPv6 address, ensure that you enable and use the IPv6 address instead: fd00:ec2::254. The IPv6 address of the instance metadata service is compatible with IMDSv2 commands. The IPv6 address is only accessible on Instances built on the Nitro System.

This example shows how to retrieve the high-level instance identity categories.

IMDSv2
[ec2-user ~]$ TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` \ && curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/dynamic/instance-identity/ rsa2048 pkcs7 document signature dsa2048
IMDSv1
[ec2-user ~]$ curl http://169.254.169.254/latest/dynamic/instance-identity/ rsa2048 pkcs7 document signature dsa2048
