Metadata Service

The metadata service is accessible from each cloud server and provides metadata via http. It provides a few basic data, such as hostname, instance-id and ssh keys, but can also provide custom user data.

The interface is compatible with the Amazon EC2 metadata service. It’s accessible from each server at http://169.254.169.254.

Example usage

$ curl http://169.254.169.254/latest/meta-data/
hostname
instance-id
instance-type
local-hostname
local-ipv4
placement/

$ curl http://169.254.169.254/latest/meta-data/instance-id
srv-sz59

See the user data guide for more examples of using the meta data service.
