[nefelim4ag]

Added CI to build a docker image on the tag

@nefelim4ag you should also generate an image for arm64 because it is perfectly compatible.

[nefelim4ag]

Yep, your point is correct, but I tried to do that and got a compilation error on arm, so I only suggest that will works

@nefelim4ag it looks like they are going to fix it in 7.0.300: dotnet/dotnet-docker#4388 (comment)

That issue will be fixed shortly.

@nefelim4ag ping!

It is now possible to do so: https://devblogs.microsoft.com/dotnet/improving-multiplatform-container-support/#build-net-images-for-any-architecture

buildx & github use qemu underneath, but i will add arm64 to test
And repo still uses the previous .Net version.

[nefelim4ag]

And same, https://github.com/Nefelim4ag/UnityNuGet/actions/runs/5278228406/jobs/9547276960#step:7:448

7.0.304 - same problem

[nefelim4ag]

@bdovaz I switched the build to 8.0-preview and it looks like it fixed the problem.
I tested the image on the amd64 & arm64 machines at least it runs and looks like works.

[bdovaz]

@nefelim4ag you forgot to use the TARGETARCH parameter, try it now with the changes I have added.

[nefelim4ag]

Yep, it's works
