(Apologies for a question, but discussions aren't enabled.)
Docker Desktop 4.26 added support for Rosetta 2 for emulating x86_64 containers on Apple Silicon Macs.
How does this interact with BuildKit? The
moby/buildkitcontainer image includes QEMU at/usr/bin/buildkit-qemu-x86_64; this is mounted into the intermediate build container at/dev/.buildkit_qemu_emulatorand everyRUNstep appears to execute/dev/.buildkit_qemu_emulator /bin/sh -c <command>.So where is Rosetta entering the mix? Is the execution of QEMU being intercepted somehow?
