Each image includes: gcc, g++, Boost, GSL, HDF5, Python 3 venv, Git, Git LFS, CMake, autotools, rsync, pkg-config, pandoc, zstd.

Prerequisites

• podman (preferred) or docker must be in PATH.
• Write access to docker.io/glvx for push targets.

Usage

# Show available targets
make

# Build all four images
make all

# Build a single variant
make build-node22

# Build and push all images
make push

# Push a single variant

Adding a new Node.js version

Add the version number to NODE_VERSIONS in the Makefile. The Dockerfile handles any version via the NODE_VERSION build argument.
