Amazon ECS on AWS Fargate now honors custom container stop signals defined in OCI images. Previously, all Linux containers received SIGTERM followed by SIGKILL during task termination. Now, the ECS container agent reads the STOPSIGNAL instruction from container images and uses that signal for graceful shutdown. Containers requiring signals like SIGQUIT or SIGINT can now terminate properly on Fargate. If no custom signal is configured, SIGTERM remains the default. This feature is available in all AWS regions.
