IDIA Singularity Registry
What IDIA Singularity Registry is
IDIA Singularity Registry is a free, open-source registry for storing and managing Singularity container images for local computers or cluster environments. Users can browse collections and download containers, while private collections are limited to logged-in users with access. Collection owners can grant pull or owner permissions through contributors and teams, and a treemap summarizes container counts per collection. The registry exposes endpoints for obtaining and saving containers rather than building them automatically. Its API is available in standard and Swagger schema views. Documentation covers Singularity client pulls and the sregistry command-line client for pushing, pulling, listing, and deleting containers. Authenticated pushes use a registry user token in an Authorization header. Direct pulls through the basic Sylabs Library API implementation require Singularity 3.3.0 or newer. Research collections include astronomy, calibration, simulation, visualization, and bioinformatics. Build or local-support requests are directed to [email protected].
Who it suits
It suits researchers and institutions that need to share Singularity images across computers or clusters. Teams needing private collections, API access, or command-line workflows can use its collaboration and client features.
What it does well
- Free and open-source registry
- Private collections support controlled access
- API and Swagger schema views available
- Supports Singularity and sregistry clients
- Collections span several research areas
What to know first
- Does not build containers automatically
- Direct pulls require Singularity 3.3.0 or newer
- Treemap viewing requires login
Verdict
IDIA Singularity Registry focuses on storing, sharing, and retrieving finished Singularity images. Its access controls, APIs, and command-line documentation support collaborative research deployments, while image building remains outside the registry.
