aspnetcore: Cannot build ASP.NET Core 7 app for Raspberry Pi 4

Is there an existing issue for this?

Describe the bug

Hey 👋🏻

I’ve been using the Docker image mu88/shopandeat:latest (an ASP.NET Core app) for years on my Raspberry Pi 4. One month ago, I switched to ASP NET Core 7.0 and everything worked smoothly.

Last week I made a little fix in the app and created a new version of mu88/shopandeat:latest. When trying to pull this image on my Raspi via docker pull mu88/shopandeat:latest, this fails with:

latest: Pulling from mu88/shopandeat
no matching manifest for linux/arm64/v8 in the manifest list entries

Which is strange because when logging into Docker Hub it seems to be okay:

I’m building my app via GitHub Actions:

• CI.yml
• Release.yml
• Dockerfile

So I’ve opened this issue in the Docker community forum. After some back and forth we discovered that when setting the platform parameter for docker build to linux/arm64 or linux/arm64/v8, dotnet build fails with cryptic errors in the .NET compilation part of my Dockerfile:

#18 [build 12/12] RUN dotnet build "ShopAndEat.csproj" -c Release -o /app/build

[/src/BizLogic/BizLogic.csproj]

I’ve attached the GitHub Actions build log.

Expected Behavior

I can build my ASP.NET Core app on GitHub Actions, set the latest tag on Docker Hub, pull it onto my Raspberry Pi 4 and successfully start the app.

Steps To Reproduce

• Create an environment similar to GitHub Actions
• Run the CI pipeline CI.yml

Exceptions (if any)

The following error occurs when build the Docker image via GitHub Actions with --platform linux/arm64:

#15 20.77 /usr/share/dotnet/sdk/7.0.102/NuGet.targets(1179,7): error MSB4018: The "MSBuild" task failed unexpectedly. [/src/DataLayer/DataLayer.csproj]
