Description
Pulling an image like python:3.5.1-alpine
(from 2015) which has a config with media type application/octet-stream
fails.
That's not an expected format from the perspective of OCI/Docker spec, and looks to be caused by a bug in distribution: distribution/distribution#1622
However, the graphdriver Docker is able to pull these images.
Also containerd has a "conversion" code that should be able to handle that image on the fly, but it looks like it's broken when used with WithPullUnpack
(which we use
moby/daemon/containerd/image_pull.go
