# Specifying a container restart policy in an Amazon ECS task definition To specify a restart policy for a container in a task definition, within the container definition, specify the `restartPolicy` object. For more information about the `restartPolicy` object, see [Restart policy](task_definition_parameters.md#container_definition_restart_policy). The following is a task definition using the Linux containers on Fargate that sets up a web server. The container definition includes the `restartPolicy` object, with `enabled` set to true to enable a restart policy for the container. The container must run for 180 seconds before it can be restarted and will not be restarted if it exits with the exit code `0`, which indicates success. ``` { "containerDefinitions": [ { "command": [ "/bin/sh -c \"echo ' Amazon ECS Sample App

Congratulations!

Your application is now running on a container in Amazon ECS.
