# 在 Amazon ECS 任务定义中指定容器重启策略 要在任务定义中为容器指定重启策略，请在容器定义中指定 `restartPolicy` 对象。有关 `restartPolicy` 对象的更多信息，请参阅[重启策略](task_definition_parameters.md#container_definition_restart_policy)。 下面的任务定义使用 Fargate 上的 Linux 容器来设置 Web 服务器。该容器定义包括 `restartPolicy` 对象，并将 `enabled` 设置为 true 以为该容器启用重启策略。容器必须运行 180 秒后才能重启，并且如果容器以退出代码 `0` 退出，则表示成功，也不会重启容器。 ``` { "containerDefinitions": [ { "command": [ "/bin/sh -c \"echo ' Amazon ECS Sample App
