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

New Docker Engine in SLES 12 Containers Module

A couple of days ago, SUSE published a major update to the Docker engine. The Containers Module now offers version 17.04-CE of the engine (docker-17.04.0_ce-98.2.s390x.rpm).

Docker CE for all distributions

The previous post mentioned that Docker provides CE packages for Ubuntu. For users of Debian, SLES, RHEL, Fedora, ClefOS, openSUSE, and Alpine, there is still an option to get the latest Docker CE version to their environment:

Docker Update in SUSE's Containers Module

SUSE has provided a version bump to docker 1.10.3 in their containers module (with a security update 4/26). Together with their latest kernel, it provides for improved performance (e.g. starting/stopping containers).

Docker 1.10 on developerWorks

The Docker page on developerWorks now provides a new Docker binary. It's version 1.10 and provided for RHEL 7 only: SUSE officially provides Docker, and Canonical has uploaded a recent Docker version to the universe archive.

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.

SLES12 officially supports Docker

Since end of 2015, SUSE also provides Docker on z through their "containers module" on top of SLES 12 (SP1). This makes SUSE the first one of the big enterprise distributions to support Docker on z Systems commercially. The package also contains base images for conveniently starting. Having decoupled Docker from the SLES 12 base vehicle through a module is a goodness, this allows for independent updates on a potentially higher frequency.
