RFE: containerd storage transport
There is a containers-storage transport, which seems to be different from the containerd storage used by Kubernetes. If this is possible, an extra feature request: Can skopeo copy to a remote containerd storage? Proxy /var/run/containers/containerd.sock similar to what --dest-daemon-host does.
contianer-storage is the transport used by CRI-O which supports Kubernetes. containerd wants to dominate it's storage so you would have to add a new transport for it to containers/image similar to the docker-daemon support. This will not be done by the upstream maintainers, since they work on CRI-O and not containerd, so the work would have to be done and maintainerd by contributors.
