    • Requires Linux and self-hosted cluster administration

Our verdict on Singularity Registry HPC

Singularity Registry HPC, also called shpc, is an open-source tool for managing container environments in high-performance computing. It is designed for cluster administrators and users who want containerized software exposed through familiar Lmod or Environment Modules commands. The project supports Singularity, Podman, and Docker technologies, making it suitable for clusters that need to accommodate more than one container format while keeping software access within established module workflows.

Its strongest differentiator is the connection between container installation and module management. shpc installs images as Lmod modules, supports the Tcl module system used by Environment Modules, and generates module files and command wrappers for installed containers. Registry options include local filesystem registries with container.yaml recipes, remote GitHub repositories, custom registry entries, and GitHub release-based pulls using gh:// identifiers. This gives cluster teams several ways to organize and distribute containerized software without moving users away from their existing module commands.

The project is distributed under the MPL-2.0 license and is intended for Linux, self-hosted deployments. Its focused design suits HPC environments where module-based access and cluster-level workflows matter more than broad registry administration. However, it is not a general-purpose registry with a wide set of documented security and lifecycle controls, so teams prioritizing image scanning, tag immutability, retention policies, replication, storage quotas, or maximum image-size policies should consider a different category fit. Choose shpc for an HPC-oriented bridge between container images, registries, and module systems; choose another option when registry governance is the primary requirement.
