It&#x27;s also, in my experience, much slower (inexplicably, since apparently Docker Hub is also backed by S3 under the hood). Using the official docker registry images (only modification was to point them to a private S3 bucket w&#x2F; credentials) resulted in frequent push&#x2F;pull failures with 500 errors. Even when they succeeded, images were taking ~15-20 minutes to push. I filed a GitHub issue and the only suggestion was to decrease the chunk size, which did not improve anything.<p>Now we use quay.io and it&#x27;s much easier and faster.
