linux/arm64 - The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8)

[Backtrennpapier]

Hi,

I started to execute on a planned mail server migration over to a new setup including mailman. That setup runs on a linux/arm64 machine. It seems that there are not images for that platform available.

! mailman-core The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested 0.0s
! mailman-web The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested 0.0s

The containers will be stopped, mailman can't be run. I also discovered the older issue which maybe was never solved: #483

Are there any plans on adding support for this architecture in the near future?

Can you contribute arm64 version of the dockerfiles with CI code? I don't honestly know much about multi-platform dockerfiles and i'd love to keep them separate.

[Backtrennpapier]

Unfortunately I'm not an expert on CI, but as much as I understand the current build process if running in a circleCI pipeline needs to be adapted to cover the multi-platform build. Maybe that is already wrong. Is there any other contributor who could support with this?

Also having this problem.

I have enabled amd64 emulation using

docker run --privileged --rm tonistiigi/binfmt --install all

the mailman-core container starts, however, the mailman-web container is in a kind of crash-loop where it exits and restarts right after something with uWSGI

e.g. docker logs -f mailman-web:

File “/usr/lib/python3.12/site-packages/django/contrib/sites/locale/hu/LC_MESSAGES/django.po” is already compiled and up to date.

Been down the emulation route and landed in the same problem. I concluded that besides it not working it is also a very inefficient use of resources on a virtual server. Instead I migrated to an amd64 arch and mailman on that still requires some memory, which will not get better emulating it.
In the meantime maybe @midzelis provided the solution for the arm64 images.

@maxking could you please review the PR of @midzelis and if acceptable, merge it and trigger a new release? Thank you!
