Getting started with Minikube: Kubernetes on your laptop

Filed under
HowTos

Minikube is advertised on the Hello Minikube tutorial page as a simple way to run Kubernetes for Docker. While that documentation is very informative, it is primarily written for MacOS. You can dig deeper for instructions for Windows or a Linux distribution, but they are not very clear. And much of the documentation—like one on installing drivers for Minikube—is targeted at Debian/Ubuntu users.

Graphics: Wayland's Weston, AMD, GitLab, NVIDIA

  • Wayland's Weston Switching Over To The Meson Build System
    Complementing the Meson build system support for Wayland itself, the Weston reference compositor now has been Meson-ized. Pekka Paalanen and Daniel Stone, both of Collabora, have landed the Meson build system support for the Weston compositor. At this stage the new build system should be fully working and correct.
  • AMDGPU DC Gets Polaris Corruption Fix, Some Code Refactoring
    AMD has published their latest batch of "DC" Display Core patches for the AMDGPU Linux kernel driver. This batch of 45 patches against this display code for the AMDGPU Direct Rendering Manager driver has some code cleanups and refactoring, changes some error messages to just warnings, and has a display corruption fix affecting some Polaris hardware.
  • Investigating GitLab
    The Direct Rendering Manager (DRM) kernel subsystem is a fairly small part of the kernel, he said. It is also a fairly small part of the open-source graphics stack, which is under the X.Org umbrella. DRM sits in the middle between the two, so the project has learned development tools and workflows from both of the larger projects. The kernel brought DRM into the Git world in 2006, which was just a year after Git came about; it was a "rough ride" back then, Vetter said. With Git came "proper commit messages". Prior to that, the X.org commit messages might just be a single, unhelpful line; now those messages explain why the change is being made and what it does. The idea of iterating on a patch series on the mailing list came from the kernel side as did the "benevolent dictator" model of maintainership. DRM, the X server, Wayland, and others all followed that model along the way. From the X.Org side came things like the committer model; in Mesa, every contributor had commit rights. That model has swept through the graphics community, so now DRM, the X server, and Wayland are all run using that scheme. Testing and continuous integration (CI) is something that DRM has adopted from X.Org; the kernel also does this, but DRM has adopted the X.Org approach, tooling, and test suites. For historical reasons, "almost everything" is under the MIT license, which comes from X.Org projects as well. There has been a lot of movement of tools and development strategies in both directions via the DRM subsystem. He thinks that using GitLab may be "the next big wave of changes" coming from the user-space side to kernel graphics, and maybe to the kernel itself eventually. This won't happen this year or next year, Vetter predicted, but over the next few years we will see GitLab being used more extensively.
  • AMDGPU For Linux 4.20 Gets The Final Radeon RX 590 Fix, Adds The New Vega PCI IDs
    With just over one week to go until the expected Linux 4.20 kernel release, Alex Deucher of AMD today sent in the latest batch of fixes to the DRM tree for landing at the end of this cycle. Notable about this latest set of "fixes" for the AMDGPU kernel graphics driver are: - The final Radeon RX 590 fix so this newer Polaris GPU no longer hangs under load. So once this Linux 4.20 material is merged to mainline, this month-old Polaris graphics card should now be happily running on Linux -- assuming you also have the latest Polaris firmware files and a recent version of Mesa. See our Radeon RX 590 benchmarks article for more details.

OpenSUSE/SUSE: 2018-2019 Elections Underway, SUSE Linux Enterprise 12 Service Pack 4, and 'Making the Selection' (Storage)

  • 2018-2019 Elections Underway with Calls for Candidates and New Members
    Earlier this week, on Tuesday, Dec. 11, 2018, the Elections Committee posted the Schedule for the 2018-2019 openSUSE Board Elections, along with the announcement of a Membership Drive and a call for nominations and applications for Candidates to fill three vacant seats on the openSUSE Board. The annual Board Elections are normally expected to run in November and December, with ballots cast and results published in time for the newly-elected Board Members to take their seats on the Board at the beginning of January. However, some additional work needed to be completed for this election, and the elections were delayed in part to accommodate the additional work.

  • Making the Selection
    You’ve likely read or heard a lot about today’s data explosion and how it’s affecting enterprises. After combing through all the overexcited rhetoric about how quickly data is multiplying or how many petabytes you’ll soon have to handle, one thing remains clear: You need to find a new way to store and manage your data or you’ll get left behind. While that mandate puts pressure on your organization to act quickly, it’s also the catalyst to a whole new world of exciting opportunities. More data can mean deeper, more accurate insights into your operations and customer needs, which empowers you to streamline processes and personalize experiences like never before. More data can also lead to greater innovation and new sources of revenue.

Programming/Development: mental illness, newt, and more

  • One developer's road: Programming and mental illness
    The next year, I went to college and learned about SUSE Linux 6.1 and the Java SE 1.2 programming language. Another student introduced me to free software and the GNU GPL License and helped me install SuSE 7.1 on my new Compaq Evo N160c notebook. There was no more Microsoft software on my computer. The GNU/Linux operating system was exactly what I wanted, offering editors, compilers, and a command line that did auto-completion. Six months later, I installed Debian GNU/Linux. Since YaST2 was just a front end to configuration files, I had to use Debian Potato. My bootloader of choice was LILO, and the Second Extended File System was reliable—not buggy, like ReiserFS. In spring 2002, I read a book about the C programming language. I wanted to learn to do UIs like javax.swing, and a friend recommended Gtk+ 2.0, which was about to be released. At this point, I stopped using the KDE Desktop Environment. Gnome 2 was different and provided anti-aliased fonts with hinting. I used it to play Chromium B.S.U., and KNOPPIX did the magic.
  • newt
    I've been helping teach robotics programming to students in grades 5 and 6 for a number of years. The class uses Lego models for the mechanical bits, and a variety of development environments, including Robolab and Lego Logo on both Apple ][ and older Macintosh systems. Those environments are quite good, but when the Apple ][ equipment died, I decided to try exposing the students to an Arduino environment so that they could get another view of programming languages. The Arduino environment has produced mixed results. The general nature of a full C++ compiler and the standard Arduino libraries means that building even simple robots requires a considerable typing, including a lot of punctuation and upper case letters. Further, the edit/compile/test process is quite long making fixing errors slow. On the positive side, many of the students have gone on to use Arduinos in science research projects for middle and upper school (grades 7-12). In other environments, I've seen Python used as an effective teaching language; the direct interactive nature invites exploration and provides rapid feedback for the students. It seems like a pretty good language to consider for early education -- "real" enough to be useful in other projects, but simpler than C++/Arduino has been. However, I haven't found a version of Python that seems suitable for the smaller microcontrollers I'm comfortable building hardware with.
