Amazon Elastic Container Service (ECS) now supports the capability for customers to lookup the runtime container IDs of containers running as part of an ECS task. Previously, customers had to stitch together multiple APIs to associate the runtime container ids of containers to the respective ECS task. This association was useful for use cases such as debugging. Now, the describe-tasks and stop-task APIs return the runtime container id for all the containers within an ECS task. This means customers have a simplified workflow to diagnose errors by searching through log files for the failed containers and mapping them to respective tasks.
