Kubic is now a certified Kubernetes distribution

January 24th, 2019 by

Published by Richard Brown on Jan 22, 2019 on kubic.opensuse.org

Certified Kubernetes

The openSUSE Kubic team is proud to announce that as of yesterday, our Kubic distribution has become a Certified Kubernetes Distribution! Notably, it is the first open source Kubernetes distribution to be certified using the CRI-O container runtime!

What is Kubernetes Certification?

Container technologies in general, and Kubernetes in particular, are becoming increasingly common and widely adopted by enthusiasts, developers, and companies across the globe. A large ecosystem of software and solutions is evolving around these technologies. More and more developers are thinking “Cloud Native” and producing their software in containers first, often targeting Kubernetes as their intended platform for orchestrating those containers. And put bluntly, they want their software to work.

But Kubernetes isn’t like some other software with this sort of broad adoption. Even though it’s being used in scenarios large and small, from small developer labs to large production infrastructure systems, Kubernetes is still a fast-moving project, with new versions appearing very often and a support lifespan shorter than other similar projects. This presents real challenges for people who want to download, deploy and run Kubernetes clusters and know they can run the things they want on top of it.

When you consider the fast moving codebase and the diverse range of solutions providing or integrating with Kubernetes, that is a lot of moving parts provided by a lot of people. That can feel risky to some people, and lead to doubt that something built for Kubernetes today might not work tomorrow.

Thankfully, this a problem the Cloud Native Computing Foundation (CNCF) is tackling. The CNCF helps to build a community around open source container software, and established the Kubernetes Software Conformance Certification to further that goal. Certified Kubernetes solutions are validated by the CNCF. They check that versions, APIs, and such are all correct, present, and working as expected so users and developers can be assured their Kubernetes-based solutions will work with ease, now and into the future.

Tumbleweed Starts Year with New Plasma, Applications, VIM, curl

January 18th, 2019 by

This new year has brought several updated packages to users of openSUSE’s rolling release Tumbleweed.

Three snapshots have been released in 2019 so far and among the packages updated in the snapshots are KDE’s Plasma, VIM, RE2, QEMU and curl.

The 20190112 snapshot brought a little more than a handful of packages. The new upstream Long-Term-Support version of nodejs10 10.15.0 addressed some timing vulnerabilities, updated a dependency with an upgrade to OpenSSL 1.1.0j and the versional also has a 40-seconds timeout that is now applied to servers receiving HTTP headers. The changelog listed several fixes for the highly configurable text editor with vim 8.1.0687, which should now be able to be built with Ruby 2.6.0 that was released at the end of December. Google’s re2 20190101 offered some performance tweaks and bug fixes. The fast real-time compression algorithm of zstd 1.3.8 has better decompression speed on large files. There was a change in the yast2-firewall package, which arrived in the the 20190110 snapshot, that allows new ‘forward_ports’, ‘rich_rules’ and ‘source_ports’ elements in zone entries with yast2-schema 4.1.0.

KDE’s Plasma 5.14.5 arrived in snapshot 20190110; the update fixed the max cache limit for Plasma addons and there were updates for Breeze GTK, Discover, KWin, Plasma Workspace, Powerdevil and more. The Intel tool that provides powersaving modes in userspace, kernel and hardware, powertop 2.10, enabled support for Intel GLK, which was formerly known as Gemini Lake, and support for Intel CNL-U/Y. The geolocations services package geoclue2 2.5.2 had a change that allow multiple clients on the same D-Bus connection and adds an application programming interface (API) for it, which was mainly done for the Flatpak location portal. The IRC client irssi 1.1.2 had multiple fixes and synced a new script. GNOME’s jhbuild 3.28.0 enabled a build of libosinfo tests. Translations were update for Czech with libstorage-ng 4.1.75 through Weblate and several YaST packages were updated, including yast2 4.1.48 and yast2-multipath 4.1.1, which had a fix for the use of a random file name.

The first snapshot of the year was extremely huge. Snapshot 20190108 updated more than a hundred packages. KDE’s Application 18.12.0 were updated and it brought more than 140 bugs fixes for applications like Kontact Suite, Cantor, Dolphin, Gwenview, KmPlot, Okular, Spectacle, Umbrello and more. The update of curl 7.63.0 had a fix for IPv6 numeral address parser along with several other fixes and a support session resume with TLS 1.3 protocol via OpenSSL. Apparmor 2.13.2 fixed a syntax error in rc.apparmor.functions, which could cause policy load failures. The Linux Kernel 4.19.12 was in the first snapshot of the year and should move closer to the latest stable version in the coming weeks. Various fixes and compatibility tweaks were made with the update of libreoffice 6.1.4.2, which removed some patches. The compression format package brotli 1.0.7 now has faster decoding on ARM. The newest version of claws-mail 3.17.3, added support for TLS Server Name Indication (SNI), which enables the sending of a hostname, if available, to the server so that it can select the appropriate certificate for a domain; this is useful for servers that host multiple domains on the same IP address. Other noteworthy updates were  Python-setuptools 40.6.3, qemu 3.1.0 and squid 4.5.

All snapshots have either logged or are treading as moderately stable with a rating of 83 or above, according to the Tumbleweed snapshot reviewer. There are more than 300 packages in staging that will likely be released in several snapshots over the coming weeks.

Latest Tumbleweed Snapshot Brings Major Versions of Flatpak, qemu, Thunderbird , Nano

September 14th, 2018 by

Since the last openSUSE Tumbleweed update, three snapshots have been released and the latest snapshot has brought two new major versions of both Flatpak and qemu.

On the heels of the Libre Application Summit last week, which is a conference focusing on sandboxing and application distribution, a new major version of Flatpak was released in Snapshot 20180911. Flatpak 1.0 marks a significant improvement in performance and reliability, and includes a big collection of bug fixes with a collection of new features. Naturally, libostree 2018.8 was updated with Flatpak and added a new feature that provides an auto-update-summary config option for repositories. Full-system emulation with qemu 3.0.0 isn’t necessarily significant. The changelog states not to “read anything into the major version number update. It’s been decided to increase the major version number each year.” Yet there is improved support for nested Kernel-based Virtual Machine (KVM) guests running on Hyper-V. The project did emphasized that ongoing feature deprecation is tracked at both http://wiki.qemu-project.org/Features/LegacyRemoval and in Appendix B of the qemu-doc.* files installed with the qemu package. Mesa 18.1.7 had a handful of fixes and once again added wayland to egl_platforms. The Linux Kernel 4.18.7 added support for Intel Ice Lake microarchitecture in the snapshot. There were several other minor updates in the snapshot, but the nodejs10 update to version 10.9.0 brought a few Common Vulnerability and Exposure (CVE) fixes and upgraded dependencies to OpenSSL 1.0.2.

Mozilla Thunderbird also received a major version update this week in snapshot 20180910. Thunderbird 60.0 improved message handling and composing and also provided Internet Message Access Protocol (IMAP) fixes. A list of CVEs were addressed with the update and the email client also added support for OAuth2 and FIDO U2F. Pixel format translation library babl updated its license to LGPL 3.0 in with the version update to 0.1.56. The library and command-line tool for transferring data using various protocols known as curl had several changes in version 7.61.1 and warn the user if a given file name looks like an option. The GNOME Web browser package epiphany 3.28.4 fixes a crash on homedepot.com and improved the performance of adblocker. The 4.18.6 kernel was made available in this snapshot. Text editor nano 3.0  also had a major version update and provided some speed improvements. Pdf renderer poppler 0.68.0 added Reason and Location to SignatureInfo. Web developers will be happy to see webkit2gtk3 2.22.0. The updated webkit2gtk3 package provides a new JavaScriptCore GLib application programming interface (API) and added playbin3 support to GStreamer media backend.

Tumbleweed Snapshots Update Fonts, Perl, Python Packages

April 27th, 2017 by

openSUSE Tumbleweed snapshots this week gave many newer versions of Perl and Python packages, but several other packages were updated in the repositories including some open fonts.

Google and Adobe fonts were updated in snapshots 20170424 and 20170420 with google-croscore-fonts and adobe-sourcehansans-fonts being added to the repositories respectively.

Besides the google-croscore-fonts in snapshots 20170424, users can get a fix for the CD/DVD burning software Brasero, which provided a patch for Grub2 that fixes builds with the GNU Composite Compilers, and kdebase4-workspace offers a diff to fix an error reported by GCC7, which should be helpful as Tumbleweed works closer to adapt the newest GCC. The snapshot also delivered a patch for VirtualBox that will provide an eventual Application Programming Interface change for the release of Leap 42.3. (more…)
