The author shares a surprising discovery: you can use S3 as a container registry by exposing an S3 bucket through HTTP, allowing for docker pulling directly from it. S3 proves to be significantly faster than ECR in terms of upload speed due to its ability to handle parallel uploads. This unconventional method challenges the traditional approach of using container registries like DockerHub or ECR. While experimental, the use of S3 as a container registry shows promise for optimization. The author explores the technical details behind this method and reflects on the potential implications for the future of hosting container images.
