QUESTION
What happens if the runner fails?
ANSWER
The runner is governed by a Runner Management Mode (mng) systemd service in the ASG EC2 VM that orchestrates and manages the runner container within a docker systemd service.
The mng daemon is responsible for fetching the install runner image version from the Nuon control plane and overseeing the lifecycle of the runner process including changing its version and restarting it.
