Registry Option: SUSE Portus

An Open Source alternative to Docker Trusted Registry is Portus from SUSE. This is a front end to a private Open Source registry that allows for fine grained control of registry access and content: it can manage users, teams, and namespaces (no, not the kernel ones). It can integrate with LDAP for authentication and offers an audit trail, and can be extended for security scanning.

To play with Portus, we need:

1. docker-compose.
2. a private registry
3. Portus

Portus

As an extension to distribution/registry, SUSE has created an open source project called Portus. Portus comes offers a web UI and good control over users and teams dealing with images in a registry.
