Pull request overview

This PR parameterizes Docker builds by introducing build arguments for OS, CUDA version, and component versions, enabling the CI pipeline to build multiple configurations through an extended GitHub Actions matrix strategy.

Key Changes:

Dockerfile now accepts build arguments (OS, CUDA_VERSION, OPTIX_VERSION, GEANT4_VERSION, CMAKE_VERSION) for flexible image builds
GitHub workflow expands from single "release/develop" targets to a matrix of 36 combinations (3 OS × 4 CUDA versions × other parameters)
Base image changed from nvcr.io/nvidia/cuda to nvidia/cuda registry

File	Description
Dockerfile	Parameterized OS and component versions using ARG directives; changed base image registry and converted DEBIAN_FRONTEND to ENV
.github/workflows/build-pull-request.yaml	Extended build matrix to test multiple OS/CUDA combinations with exclude/include rules; added build-args passthrough

.github/workflows/build-pull-request.yaml

+        cuda_version: [11.8.0, 12.5.1, 12.9.1, 13.0.2]
+        optix_version: [7.7.0]
+        geant4_version: [11.3.2]
+        cmake_version: [3.22.1]


The CMake version 3.22.1 in the workflow doesn't match the default version 4.1.2 specified in the Dockerfile. Since CMake 4.1.2 doesn't exist (CMake is currently in the 3.x series), this inconsistency needs to be resolved. Update the Dockerfile's default CMAKE_VERSION to match this valid version (3.22.1).

Dockerfile

+ARG CUDA_VERSION=12.4.0

-ARG DEBIAN_FRONTEND=noninteractive
+FROM nvidia/cuda:${CUDA_VERSION}-devel-${OS} AS base


The base image has changed from nvcr.io/nvidia/cuda (NVIDIA's official container registry) to nvidia/cuda (Docker Hub). While both registries host NVIDIA CUDA images, this change may affect image availability, update frequency, or require authentication changes. Ensure this is intentional and that the nvidia/cuda repository on Docker Hub supports all the specified CUDA versions (11.8.0, 12.5.1, 12.9.1) and OS combinations (ubuntu22.04, ubuntu24.04, rockylinux9).

.github/workflows/build-pull-request.yaml

+         - os: [ubuntu22.04, rockylinux9]
+           cuda_version: 11.8.0


The matrix exclude syntax is incorrect. The os and cuda_version fields should not be arrays in the exclude section. Each exclusion should be a separate item. For example:

exclude: - os: ubuntu22.04 cuda_version: 11.8.0 - os: rockylinux9 cuda_version: 11.8.0

This will cause the workflow to fail or not exclude the intended combinations.

Suggested change

- os: [ubuntu22.04, rockylinux9]

cuda_version: 11.8.0

- os: ubuntu22.04

cuda_version: 11.8.0

- os: rockylinux9

cuda_version: 11.8.0

curl | tar downloads and extracts external archives (CMake, Geant4, plog, optix) over HTTPS without any signature or checksum verification. An attacker compromising DNS/CA or the upstream repo could serve a malicious tarball that gets executed during the build, resulting in a supply-chain compromise. Verify integrity before extraction, e.g., download detached signatures and verify with GPG or check a published SHA256 digest prior to tar -xz, for example:

curl -sL -o cmake.tar.gz https://github.com/Kitware/CMake/releases/download/v${CMAKE_VERSION}/cmake-${CMAKE_VERSION}.tar.gz curl -sL -o cmake.tar.gz.sha256 https://github.com/Kitware/CMake/releases/download/v${CMAKE_VERSION}/cmake-${CMAKE_VERSION}.tar.gz.sha256 sha256sum -c cmake.tar.gz.sha256 tar -xz --strip-components 1 -C /opt/cmake/src -f cmake.tar.gz

 && cmake --build /opt/geant4/build --parallel --target install \
 && rm -fr /opt/geant4


curl | tar fetches and extracts Geant4 sources without verifying signatures or checksums. A malicious or tampered archive would be executed during the build (cmake --build), enabling a supply-chain attack. Mitigate by verifying a trusted SHA256 or GPG signature before extraction, then use tar -f on the verified file.

curl | tar downloads and extracts optix sources without any checksum or signature verification. A tampered archive could inject malicious code into the image during build. Fix by downloading to a file and validating a trusted SHA256 or GPG signature before extraction, then run tar -f on the verified file.
