Hi all,

Is there any way to modify/add the "user-data" to an instance that is already created and running?

The documentation only said: use the command "nova boot" with variable --user-data, but I can't found documentation about instances already running on openstack,

Any help is welcome!

What's the point of adding user-data to a running VM. As I understand, user-data will be run with cloud-init (when booting instances). If the instances are already running, what events will trigger user-data?

(Please correct me if I'm wrong)

A example: I have a ssh key for puppet service, this deploy works with user-data and I need change the old key for security reason.
