I introduce OpenSDS that is an open source community working to address storage integration challenges. I remark technology. OpenSDS can manage LVM, Ceph, Cinder, and more as a software defined storage. and We can use OpenSDS in Kubernetes through CSI, Flexvolume, and Service Catalog. therefore, Kubernetes can use software defined storage by OpenSDS. I draw overview of Kubernetes - OpenSDS - stora...

In this talk we could see how easy it is to deploy and configure Ceph ready k8s cluster on top of Kubic. And setup Ceph on top of it with Rook (rook.io). We would see couple of examples for Openstack and Vagrant to run such clusters for your CI and development environments. In this talk we could see how easy it is to deploy and configure Ceph ready k8s cluster on top of Kubic. And setup Ceph on to...

GNU Health is the Free/Libre Health and Hospital Information System that is included in openSUSE. GNU Health combines the socioeconomic determinants of health with state-of-the-art technology in bioinformatics and clinical genetics. It provides holistic picture of the person, from the biological and molecular basis of disease to the environmental determinants of health. In addition, it manages the...

In the past UX design was a commodity in the paid consumer world, where companies like Facebook, Google, Uber would invest millions on. Today the gap is closing. Enterprise and Open Source applications are in need of better UX too. On the other hand, many companies of all different sizes struggle with today's IT agendas: bleeding edge software, agile development, short time-to-market, etc., and th...

YubiKeys are handy little USB tokens that allow for hardware-based cryptography, which are becoming ever more prevalent. They provide support for a great variety of cryptographic protocols and standards, and offer several modes of operations. While this makes them very versatile, it can also be somewhat confusing, especially when you are only getting in touch with them for the first time. This tal...

Japan openSUSE User Group publishes a technical magazine every half year. The title of the magazine is Geeko Magazine. It consists of technical articles on openSUSE and applications running on openSUSE. For example, the latest issue of the magazine contains articles like "Launching Kubernetes Cluster with Kubic in 10 minutes", "Accessing to Google Drive from openSUSE", and "How to enable HTTPS wit...

I have been a part of the Taiwan openSUSE community for almost a year. During this time, I was a volunteer at the openSUSE Asia Summit 2018, and I attended monthly openSUSE meet-ups. It feels great to have a group of people with whom to study and share knowledge. In the new year, I am curious about how I can contribute to the community with my expertise as an OS certification technical manager in...

Right now many RPM spec files contain large parts of boiler plate code. In the current development cycle of RPM we try to help reducing this clutter. We hope we can make packaging easier by providing means to have pre-arranged building blocks and offer more control over larger sets of packages. This will also change the relation between RPM as a multipurpose tool and the single package/packager by...

As the world moves more and more towards containerised solutions, a number of real questions start to appear. - What is the perfect platform for running containers atop? - How to use this platform as part of a flexible, scalable, highly available infrastructure fabric? - How to minimize the maintenance and administration of this platform at scale? Many of these problems are well answered in enterp...

"Kubernetes" is one of the most popular and famous container orchestration open source software. And now, there are so many Kubernetes environments and deployment tools such as SUSE CaaS Platform, minikube, kubeadm, Rancher, GKE/AKS/EKS, etc. So, we can use or build a Kubernetes cluster with them very easily. However, it also prevents opportunities to understand Kubernetes technologies themselves...

Kubic with its MicroOS core is an exciting distribution that takes much of the cool stuff we're doing in Tumbleweed, adds solutions to the problems of updating a running system, and is becoming the perfect base system for running containers. But in openSUSE, running server stuff is only half the fun. Why should servers be the only platform enjoying automatic, atomic, "auto-rollbackable" system upd...

In one corner, we have Zypper: the successor to the motley of package management options from Ximian and SuSE. Created after the merger of the Ximian and YaST package manager teams, it was a pioneer in using the SAT solver for package management and proved that it worked well at scale in a large and popular Linux distribution platform (SUSE Linux). It spawned the development of libsatsolver, which...

Presenter: Thomas Di Giacomo In this session we will first briefly describe how the openSUSE community and SUSE have been historically (well since Leap/Tumbleweed, not going back to the days before) collaborating together, e.g. Gnome and SUSE Linux Desktop, KDE and packagehub, then look at some of the more recent activities around MicroOS, container engines and tools, container networking such as...

Wir haben im Chaotikum mal wieder eine technische Lösung für ein soziales Problem gefunden: Damit alle Bescheid wissen, wann welche Veranstaltungen im Nobreakspace stattfinden und wann man vielleicht vorher mal ein wenig im Space aufräumen könnte, haben wir einen Chatbot in unserem Matrix-Chatraum, der kommenden Veranstaltungen vorher ankündigt. Weitere Details zum Projekt finden sich in unserem W...
