Provide a way to create manifest config conform to mounting the image as a volume with containerd/crio etc #457
Description
What would you like to be added?
Provide a way to push an artifact layer with a manifest config containing the mimics of an oci runtime image.
See:
- ImageVolume does not support OCI spec Guidelines for Artifact Usage containerd/containerd#11907
- Mount OCI Artifacts containerd/containerd#11381
It will still take a lot of time util oci artifacts will be supported natively, see https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/4639-oci-volume-source#kubelet-and-container-runtime-interface-cri-support-for-oci-artifacts
Why is this needed for ORAS?
One of the main benefits from oras would be to mount the images into a pod as a volume. Currently that is not possible as containerd does not support the oci artifact spec. You need the rootfs element with the diffId digest of the uncompressed layer.
Are you willing to submit PRs to contribute to this feature?
- Yes, I am willing to implement it.
