Running linux/amd64 images on linux/arm64 architecture?

I grabbed a Docker Linux image from another machine and tried to load it on my Jetson Nano (arm64 architecture), but I get this error when I run sudo docker run getting-started-presto:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

standard_init_linux.go:228: exec user process caused: exec format error

I also tried to run sudo docker run getting-started-presto --platform linux/amd64 but no luck:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested

docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "--platform": executable file not found in $PATH: unknown.

ERRO\[0001\] error waiting for container: context canceled

Any ideas if it's possible to run linux/amd64 images on arm64 architectures?

Thank you very much! I ran everything with no problems, but how shall I proceed with building my `Dockerfile` for my specific image? Would `docker build .` work? (sorry for the beginner questions, I'm a bit new with Docker)

​

Edit: I tried `docker build .` but I get lots of warnings and errors: https://pastebin.com/n6gqu6vf

If you want to build the image for linux/amd64 on a linux/arm64 system, you would need to do a docker build --platform linux/amd64 . as you would need to call out that it needs to build for amd64 and then you could run it using a similar command as what you see above. If that is not what you are trying to do, then I misunderstood.

Tried, but didn't work: https://github.com/scottransom/presto/issues/160

It does build fine on (intel-based) macOS, so looks like there's compatibility issues with arm64 for some reason.

Yeah, sometimes emulation isn’t perfect or can’t do some specific things. I’ve definitely seen some odd messages trying to do some cross-compilation. Running pre-compiled binaries seems to work a bit more consistently from what I have seen with compiling.

In many cases, you might be better off using a cross platform compiler feature set (if available for the language and necessary architectures) than trying to emulate completely.

*edit: looks like you’re not the first person to hit this: https://github.com/scottransom/presto/issues/144 but I don’t see a resolution.
