Container Publishing (No Dockerfile)

Core Principles

1. No Dockerfile needed — The .NET 10 SDK builds OCI-compliant container images directly from dotnet publish /t:PublishContainer. No Dockerfile to write or maintain.
2. Chiseled images for production — Use noble-chiseled base images: no shell, no package manager, 7 Linux components vs 100+. Smallest attack surface.
3. Non-root by default — .NET 10 container images run as the app user automatically. Never override to root in production.
4. Configuration in the .csproj — All container settings are MSBuild properties, versioned with your project. No separate files to drift.

Patterns

Minimal Container Publish

No project file changes needed. Just publish:

dotnet publish /t:PublishContainer --os linux --arch x64
