Briefing
Northstar's platform team is standing up the launch API on a fresh host, and nothing downstream (networking, storage, the move to Kubernetes) can be tested until one API container stays up.
The image built cleanly about fifteen minutes ago and a container was created from it straight away.
That container stopped almost immediately with exit status 0 and stayed stopped.
Dev reads the clean exit as the app shutting itself down politely over an unset environment variable, which is how the service behaved on the old hosts.
The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.
