Will ECS terminate a task if health check fail during service update termination phase?

Question

If I have health check defined for 30 second interval and 3 failures allowed and termination grace period for task set to 3 minute.
Assuming that on SIGTERM due to service update, I stop receiving new requests and task takes 150 seconds to gracefully stop, will ecs terminate my container after 90 seconds since its health checks will fail due to webserver not responding to new requests.

This is a concern because I had similar issue with k8s https://github.com/kubernetes/kubernetes/issues/107473

Answer

From experience, ALB/NLB reports the status of the target to ECS to indicate to stop the task. So with the 30x3 you mentioned, that's 90 seconds the task will have been running. That does not take away the `StopTimeout` set for the container on SIGTERM. So in total your task will be running 90 seconds + (30s (default for `StopTimeout`) to SIGKILL || graceful shutdown -> which ever comes first.
