AWS ECS Restart Policy

I've inspected one of the docker containers I have running in my ECS cluster and it has a blank for the restart policy ("{{ .HostConfig.RestartPolicy.Name }}"). I'm unsure what ECS does in the case of a failure but I would like to change the policy to one that restarts the container instance if the cmd running in the instance fails. Is it possible to change the restart policy on docker containers in an ECS cluster?
