2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 8 stars8 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

/dockerfile — Generate a Dockerfile
Input examples
/dockerfile .NET 10 Minimal API --prod
/dockerfile Angular 20 nginx --prod
/dockerfile Python FastAPI
/dockerfile Go service --prod
/dockerfile --dev fullstack .NET + Angular (docker-compose dev)
Process
- Detect the stack → pick the right base image
- Multi-stage build: build stage → runtime stage
- Security hardening
- L1 approval → Write
Mandatory rules
- Multi-stage build — separate build and runtime
- Non-root user — NEVER run the container as root
- Specific tag —
mcr.microsoft.com/dotnet/aspnet:10.0-alpine, NEVERlatest - COPY before RUN — leverage layer caching (copy csproj/package.json first, restore, then copy source)
- .dockerignore — exclude bin/, obj/, node_modules/, .git/
- HEALTHCHECK — mandatory for production
- NEVER hardcode secrets/connection strings — use env vars
- Alpine-based whenever possible (small image size)
Output
