Amazon ECR increases image layer size limit to 200 GB
Amazon Elastic Container Registry (ECR) now supports image layers up to 200 GB for images pushed via Docker push, simplifying the packaging of large assets for container images. This change benefits users embedding LLMs, bundling genomics datasets, or packaging large binary dependencies. The new limit is available in most AWS Regions, with images pushed via AWS SDK/CLI remaining at a 50 GB limit.

- Increase maximum image layer size to 200 GB
Amazon ECR now supports image layers up to 200 GB for images pushed via Docker push, up from previous limits. This enables embedding larger datasets and dependencies directly into container images without requiring splitting or external storage.
Notes (1) ›
- Limitations and availability
Images pushed using the AWS SDK or CLI (UploadLayerPartAPI) are still limited to 50 GB per layer. This feature is available in all AWS Regions and partitions where Amazon ECR is available, except for the Middle East (Bahrain) and Middle East (UAE) Regions.
