Summary
When updating a service or otherwise scaling out ECS tasks for a service that uses Service Discovery, tasks are being stopped before reaching the TTL of the service discovery record(s).
Description
When updating a service or otherwise scaling out ECS tasks for a service that uses Service Discovery, tasks are being stopped before reaching the TTL of the service discovery record(s).
To reproduce - create an ECS service from a simple "hello world" type task definition that runs forever and does nothing. Set min healthy to 100, max to 200, count to 1. Setup service discovery and create a DNS record with a long TTL, say 300s. Update the service to use a new revision of the task definition (no changes to the task def needed), and note that the tasks are stopped before the TTL time is reached.
Expected Behavior
ECS Agent should remove the route53 record(s), and then wait to stop the tasks after the TTL duration has elapsed.
Observed Behavior
ECS Agent does not wait any additional time when stopping tasks for services that use service discovery.
