Sorry I missed the details: "Does that mean you're all running asahi linux or are you somehow running linux elf binaries on macOS?" So you're running whatever linux districtuion you want or some particular flavor through Docker on Mac? And you don't have ELF binaries because you're using precompiled packages for ARM and don't need weirdo prebuilt ELFs, or you have a workaround?

We deploy containers to production, and use variants of the same containers for local development - mostly Debian. Those containers contain a mix of custom built software and packages from the distro.

Docker for Mac runs a full-blown Linux kernel last time I checked (Docker for Windows can use Windows containers). So whatever OS they run on the cloud (with OCI) these containers are going to work on the (very fast) M1/M2. The OS the Docker images are using is irrelevant. The OS running in the cloud is irrelevant. Only relevant factor is Docker for Mac as it means Linux kernel overhead. But this is offset by M1/M2. Clever setup!

  Exactly this. Plus as the Apple virtualisation framework now implements pretty standard virtual hardware - it uses virtio - we are finding things work vastly better in Docker for Mac - particularly as we can use virtiofs etc to pass files through from the host.

    Yes, but pretty much in the same sad state as they were a few years ago. We're running a few in production and next time we touch it we're replacing them with Windows Server Core EC2 instances built from baked images. Note on Linux containers: Running Linux containers on Windows requires the use of LinuxKit or WSL. Docker Desktop for Windows requires you switch modes between Linux container mode and Windows container mode as you can't run both simultaneously. A workaround is to install an additional Docker daemon inside the WSL environment. Most people are going to install Docker Desktop and use WSL in Linux mode. It's fine. Hopefully my facts are up-to-date.

      Windows containers have improved quite a lot in Windows 11.

  The interesting thing is, how is Docker for Mac able to run x86 containers at speed when Apple's Developer Documentation for Rosetta says it can't be used for virtual machines? Or have they just embedded the QEMU on-demand translator with binfmt_misc in the ARM virtual machine and the M1/M2 is just powerful enough to make users not notice what's going on?

    Rosetta can be used to emulate individual processes inside a linux-based virtual machine - Apple provide tooling for this: https://developer.apple.com/documentation/virtualization/running_intel_binaries_in_linux_vms_with_rosetta https://developer.apple.com/documentation/virtualization/run...
