What

Production-ready multi-stage Dockerfile and .dockerignore for the Extrudex backend API.

Dockerfile features:

  • Multi-stage build: SDK stage for build, aspnet:9.0 runtime stage for minimal image
  • Layer caching: csproj copied and restored before source for optimal Docker layer caching
  • Non-root user: Runs as for security
  • Port 8080: ASP.NET Core default in .NET 8+
  • Clean separation: No dev-only tooling in final image

.dockerignore:

  • Excludes bin/, obj/, IDE files, dev config, secrets, .md, .log

Validation:

  • ✅
  • ✅ (app starts and listens on 8080)
  • Final image: 379MB (aspnet:9.0 runtime only)

Linear

Closes CUB-65
