[BUG] Cannot run MAP Docker images on M1 Mac silicon (arm64)

Describe the bug

Hi all. I am a (relatively new) M1 Mac user – the arm64 architecture is the source of various development issues.

I am following the Getting Started instructions in monai-deploy-app-sdk/README.md.

I can successfully run monai-deploy package to create the MAP Docker image, however I cannot launch the app, i.e.: monai-deploy run

Steps/Code to reproduce bug

When I run monai-deploy run simple_app:latest input output I get the following:

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

Full output here

Expected behavior

I expected this to happen tbh – have observed similar issues when building other Docker images. To get around this issue in other projects, I've used the --platform option when running docker build which can be used to set architecture compatibility. e.g.:

docker build --platform linux/amd64 .

I started looking into the monai-deploy code – would it be possible to update the monai-deploy package command with an option to pass --platform?

Environment details (please complete the following information)

• OS/Platform: macOS 12.0.1 (Monterey) – M1 cpu
• Python Version: 3.9.7
• Method of MONAI Deploy App SDK install: [pip, conda, Docker, or from source] conda using the repo requirements.txt
• SDK Version: pip version installed as of yesterday

Additional context

Thanks!

I've also tried using a Rosetta2 terminal (which is supposed to emulate an Intel CPU architecture) as well, but no luck so far.

Start with the Getting Started instructions in monai-deploy-app-sdk/README.md and trace the monai-deploy package and monai-deploy run entry points. Check how the Docker image is built and launched, then verify on an M1 Mac that the requested platform can be selected and the simple_app:latest example starts successfully.
