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 IMDS: 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 IMDS is compatible with IMDSv2 commands. The IPv6 address is only accessible on instances built on the AWS Nitro System.

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

IMDSv2

PS C:\> [string]$token = Invoke-RestMethod -Headers @{"X-aws-ec2-metadata-token-ttl-seconds" = "21600"} -Method PUT -Uri http://169.254.169.254/latest/api/token

PS C:\> Invoke-RestMethod -Headers @{"X-aws-ec2-metadata-token" = $token} -Method GET -Uri http://169.254.169.254/latest/dynamic/instance-identity/

IMDSv1

PS C:\> Invoke-RestMethod -uri http://169.254.169.254/latest/dynamic/instance-identity/
