openSUSE Kubic Moves in a New Direction

August 9th, 2018 by

Dear Community,

It has been more than a year since the openSUSE community started the Kubic Project, and it’s worth looking back over the last months and evaluating where we’ve succeeded, where we haven’t, and share with you all our plans for the future.

A stable base for the future

Much of our success has been in the area generally referred to as **MicroOS**, the part of the Kubic stack that provides a stable operating system that is **atomicly updated** for running containers.

Not only is Kubic MicroOS now a fully integrated part of the openSUSE Tumbleweed release process, but our Transactional Update stack has also been ported to regular openSUSE Tumbleweed and Leap.

Based on the community’s feedback, the new System Role has been further refined and now includes fully automated updates out of the box.

This collaboration is continuing, with many minor changes to the regular openSUSE installation process coming soon based on lessons learned with tuning the installation process in Kubic.

Reviewing our initial premise

We haven’t just been busy on the basesystem. Our efforts with Rootless Containers continue, and you can now use the “Docker-alternative” Podman CRI-O in both Kubic and regular openSUSE. But when considering the Initial Premise of the Kubic project, it’s probably safe to say we’re not where we hoped to be by now.

Introducing Kubic Project: a new open-source project

May 29th, 2017 by

Recent years have seen tremendous growth in the container technologies market. From being a non-existent category just a few years ago to being one of the most interesting, fast development and exciting areas.

Containers change the way we think about application architecture and the speed at which we can deliver on business requirements. They provide consistency and portability across environments and allow developers to focus on building a great product, without the distraction of underlying execution details.

Today the entire application delivery supply chain is changing as the age of abstract application creation is upon us. This change is fueled by the adoption of a few key technologies,  including shared code repositories, continuous integration, continuous development, and cloud computing.  However, the ultimate driver of this movement is a software delivery mechanism: containers.

Project Kubic is a generic project for the many new initiatives related to re-designing the operating system around principles of immutable infrastructure and the usage of a stack based on Linux, docker project and Kubernetes.  The primary building block of the Kubic Project is the Container Host OS based on openSUSE Tumbleweed.

In the near future and with your support, we’ll be enabling Kubernetes and many other new features. This will allow you to easily build Container as a Service (CaaS) solutions and run them everywhere…

How can the Kubic Project help me?

  •  Traditional OS are cool and fun to hack on, but the model with a single runtime environment controlled by the OS and shared by all applications does not meet the requirements of modern application-centric IT.
  • Based on a monolithic approach, the traditional OS brings lots of challenges for managing the stacks running on top of it. With Kubic, we would like to rethink the OS by redesigning it for modern IT applications.
  • In agile environments, developers and DevOps engineers are taking responsibilities over their app and seeking control over the runtime underneath their applications, without necessarily owning the entire stack.
  • VMs provide a means for separation among applications, but this model adds resource and management overhead.

Join our Kubic Project and together we will build the next generation of Container OS
