User Data

Download schema

User data is a key/value store you can use to provide your Instance with introspective data.

There are two ways of accessing user data:

From within a running Instance, by requesting the Metadata API at http://169.254.42.42/user_dataOpen in new context (or http://[fd00:42::42]/user_data using IPv6). The scaleway-ecosystem package, installed by default on all OS images provided by Scaleway, ships with the scw-userdata helper command that allows you to easily query the user data from the Instance. For security reasons, viewing and editing user data is only allowed to queries originating from a port below 1024 (by default, only the super-user can bind to ports below 1024). To specify the source port with cURL, use the --local-port option (e.g. curl --local-port 1-1023 http://169.254.42.42/user_data).
From the Instance API by using the methods described below.
