I've created a cloud-init file using Terraform's aws_instance.user_data parameter.
This then is executed on start up, on Centos machines, by the cloud-init systemd service.
I would like to edit this file for dev/testing purposes on the fly then simply restart the said service.
To this end, where can I find the cloud-init file that contains the commands run by the cloud-init service?
On my Centos machine, this was found in the file:
/var/lib/cloud/instances/<instance-id>/user-data.txt
Where instance-id is found in the file /var/lib/cloud/data/instance-id.
