Explore the OCI image index, manifests, and configuration of a remote multi-platform image - without pulling a single byte of filesystem layers into the local Docker daemon.
Combine your knowledge of QEMU emulation, cross-compilation, and remote builders to build and push a multi-platform container image (linux/amd64 + linux/arm64) to a registry.
Save a container image as an OCI layout, extract its filesystem layers, and mount them together using OverlayFS to get a flat container-like rootfs.
Save container images as OCI layouts and explore the on-disk structure of single-platform (manifest-based) and multi-platform (index-based) images.
