Description RHOS Integration 2013-12-12 16:07:17 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/update-userdata.

Description:

A feature of Heat is to allow updates to existing compute servers triggered by changes to polled data.

Currently compute servers must poll for changes via a cfn API metadata lookup, which requires authentication to be delivered to the server, plus extra complexity in the heat template to enable this authentication.

This same data exists in the nova metadata server http://169.254.169.254/latest/user-data but it is currently not possible to update this data on a running instance.

This blueprint proposes that nova allows user_data to be updated via the server update API, with corresponding support in novaclient.
