Amazon EKS Reduces Multi-Gigabyte Container Image Pull Times to Seconds
Key points
- ML container images can be 20-30 GB, causing multi-minute pull times.
- Bottleneck was software utilization of hardware, not network or registry.
- Optimized pull pipeline now leverages existing instance resources.
- Improvements are default in EKS Auto Mode and contributed to containerd and SOCI snapshotter.
Addressing Large Image Pull Bottlenecks
Machine learning inference images, which often include deep-learning frameworks, CUDA stacks, and model weights, can reach sizes of 20 to 30 GB or more. On Amazon EKS, pulling these large images previously took several minutes, causing accelerators to sit idle and delaying application readiness. This issue was particularly problematic for production ML platforms requiring pods to be ready within two minutes.
Identifying the Root Cause
Initial investigations into the long image pull times suspected network or registry limitations due to the large data volume. However, profiling revealed that the actual constraint was how the software utilized the hardware resources already available on accelerated instances, which typically have 100 to 400 Gbps network bandwidth. The existing pull pipeline was not efficiently leveraging these resources.
Optimized Pull Pipeline Implementation
By re-architecting the image pull pipeline, Amazon EKS now fully utilizes the network bandwidth, storage throughput, and compute capabilities of its instances. This optimization has successfully reduced multi-minute image pull times to mere seconds. These improvements are now available by default in EKS Auto Mode.
Broader Impact and Contributions
The core changes developed to achieve these faster pull times have been contributed upstream to containerd and the SOCI snapshotter. This indicates that the benefits of this optimization may extend beyond Amazon EKS, potentially improving container image pulling performance in other environments that utilize these open-source components.

Reporting from
Amazon EKS has reduced the time it takes to pull multi-gigabyte container images from several minutes to seconds, particularly benefiting machine learning workloads. This improvement was achieved by optimizing the image pull pipeline to better utilize existing network bandwidth, storage throughput, and compute resources on accelerated instances.
