Is there any plan to support converting oci-layout directories or tar files? I see https://github.com/dragonflyoss/nydus/issues/436 but AFAICT it was closed without actually implementing. It would be useful for people who use a hermetic build system to be able to covert oci-layouts to nydus.

Hi @mmonaco, oci -> nydus conversion has been implemented in nydusify convert.

Sorry, but could you clarify how? I looked at the docs and the source and AFAICT file:// is only supported for nydusify copy.

Sorry, but could you clarify how? I looked at the docs and the source and AFAICT file:// is only supported for nydusify copy. The convert command is:

nydusify convert \
  --source myregistry/repo:tag \
  --target myregistry/repo:tag-nydus

You can see more details in docs
