Multi-platform image support in Docker Desktop
summary
Docker Desktop 4.12 exposes an experimental feature that replaces custom pull/push code with containerd remotes+snapshotters so image storage becomes containerd-backed; the daemon toggles via Preferences → Experimental. It demonstrably builds and runs a true multi-platform image build (linux/arm64, linux/amd64) using docker buildx, runs nginx and simple containers, and successfully pushes a multi-arch manifest to Docker Hub. Migration of existing local images is planned in a second stage and the integration aims to become default next year.
