I have ESC service with EC2 task running on an EC2 instance. The image in the EC2 task is from the ECR uri: for example: `688523422345.dkr.ecr.us-west-1.amazonaws.com/image`, I noticed that when I load this image into my EC2 task I just directly using the uri:`688523422345.dkr.ecr.us-west-1.amazonaws.com/image:latest`, because the image uri never changes and I just keep push image to update it.

However, when the image did updated on ECR, the task and service running on EC2 instance doesn't updating. I wondering why, and search on stack overflow, people told me that using `aws ecs update-service --cluster <cluster name> --service <service name> --force-new-deployment` to force the service to re-deploy. However, I just got error on not enough memory left on the instance(seems the re-deployment will create new task and it keep taking more memories, not a good solution).

How can I solve this?
