I am wondering what would happen if I remove an ECR image where we have an AWS Fargate cluster live based on that image.

• Would live containers stop working?
• Would autoscaling fail to create new instances?

This is because we want to implement lifecycle policies and I want to know if we should take precautions against expiring an image while we have a cluster deployed that is using it.

No. The live containers would continue to run.

Yes. You would not be able to deploy any new containers that use that image.

Yes, you absolutely want to take precautions to keep the current image that your deployment depends on, or the next auto-scaling event, or replacement of a crashed container, will fail.
