feat: Multi-arch Python base image #614

Closed mvgijssel closed 7 months ago

mvgijssel commented 7 months ago

ref #451

[x] What happens if we run x86_64 on macbook M1? Can we validate this alternative arch works?

nix-build test.nix
docker load < result && docker run --rm -it --platform linux/amd64 myimage:latest
> uname -a
Linux db2e968516f1 6.4.16-linuxkit #1 SMP PREEMPT Thu Nov 16 10:49:20 UTC 2023 x86_64 GNU/Linux

[x] Setup two separate nixpkgs workspaces, one for each arch
[x] Use rules_oci to combine the images into a multi arch image
[x] Remove host_python_container_platform
[x] Create changesets

Because cross compiling is very slow try:

Use cachix to cache derivations so subsequent compilations go faster (https://discourse.nixos.org/t/armv7l-builds-on-cachix/788)
Use binary cache for aarch64 as mentioned here (https://nixos.wiki/wiki/Nix_on_ARM)
Use trick from https://nixos.wiki/wiki/Cross_Compiling
