The record

Purpose: Singularity Registry Server is an open source registry for Singularity containers.
Flexible deployment: The registry is designed to support different authentication, storage, and building plugins.
Private registries: A registry can be entirely private and can use expiring tokens that can be shared.
Image transfers: Users can push and pull container images using Singularity clients, and the registry also documents a Curl API.
Web interface: The documentation describes using the interface to interact with collections.
Authentication integrations: Included plugins support LDAP, PAM, and SAML authentication.
Other integrations: Included plugins provide Globus transfers, Google Cloud build and storage, and a keystore for signing containers.
Deployment requirements: The server needs web access and a host that can install and run Docker and Docker Compose.
Security configuration: The starter web server configuration uses HTTP, and the documentation advises configuring HTTPS properly.
Signing caveat: The client documentation shows an unsigned image push using the `-U` option.
Backup responsibility: The documentation leaves storage backup strategy to the deploying institution because storage options vary.
Intended users: The project describes the registry as a non-enterprise solution catered for research scientists.
Support: The About page directs users who need help to open an issue on GitHub.
Price from: Free
