Certified Kubernetes Distribution based on openSUSE MicroOS

Certified Kubernetes Kubernetes is an open-source system for automating deployment, scaling, and management of containerised applications. Kubic uses kubeadm to provide an easy way of configuring a Kubernetes cluster across multiple machines, while our MicroOS base keeps your operating system updated automatically, with fully atomic rollbacks if required.

Micro Service OS providing Transactional (Atomic) Updates upon a read-only btrfs root filesystem

Designed to host container workloads with automated administration & patching. Installing openSUSE MicroOS you get a quick, small environment for deploying Containers, or any other workload that benefits from Transactional Updates. As rolling release distribution the software is always up-to-date.
Check out the MicroOS website for further information.


A huge pool of freshly build images for your workload

Our Container Registry offers a great choice of containers based on either openSUSE Kubic or plain Tumbleweed. Use them as a base for your project and be on the safe side by our automated rebuilds in Open Build Service to get security updates of your dependencies fast and easy – continuously tested by openQA. You can even publish your own project using the infrastructure around Open Build Service.
