Manifest lists and multi-arch images
WHAT IT TESTS: how one tag serves multiple architectures. OUTLINE: a manifest list maps platform descriptors to per-arch image manifests, the client picks by os and architecture, and pulls only that variant.
WHAT IT TESTS: whether you understand multi-architecture image distribution. ANSWER OUTLINE: a manifest list is an index that points to several platform-specific image manifests, each tagged with os and architecture and its own digest. When a client pulls redis:7, the runtime reports its platform and the registry returns the matching manifest, so an arm64 node gets the arm64 image and an amd64 node gets the amd64 one, all under one human-friendly tag.
