Fedora Workstation 31 – What's new

Filed under
GNU
Linux
Red Hat

Fedora has been leading the migration to Wayland since day one and we are not planning to stop. XWayland on demand has been an effort a lot of people contributed to this cycle. The goal is to only need XWayland for legacy X applications, not have it started and running all the time as that is a waste of system resources and also having core functionality still depend on X under Wayland makes the system more fragile. XWayland-on-demand has been a big effort with contributions from a lot of people and companies. One piece of this was the Systemd user session patches that was originally written by Iain Lane from Canonical. They had been lingering for a bit so Benjamin Berg took those patches on for this cycle and helped shepherd them over the finish line and get them merged upstream. This work wasn’t a hard requirement for Wayland-on-demand, but since it makes it a lot easier to do different things under X and Wayland which in turn makes moving towards XWayland-on-demand a little simpler to implement. That work will also allow (in future releases) us to do things like only start services under GNOME that are actually needed for your hardware, so for instance if you don’t have a bluetooth adapter in your computer there is no reason to run the bits of GNOME dealing with bluetooth. So expect further resource savings coming from this work over time.

Carlos Garnacho then spent time going through GNOME Shell removing any lingering X dependencies while Olivier Fourdan worked on cleaning up the control center. This work has mostly landed, but it is hidden behind an experimental flag (gsettings set org.gnome.mutter experimental-features "[...,'autostart-xwayland']") in Fedora 31 as we need to mature it a bit more before its ready for primetime. But we hope and expect to have it running by default in Fedora Workstation 32.

SUSE and Red Hat Leftovers

SUSE
  • Skuba on SUSE CaaS Platform 4

    With SUSE CaaS Platform 4 we heard our customers feedback and decided to change what the lifecycle of the platform looks like.

    Previous versions of SUSE CaaS Platform included an administrator node that despite being useful for managing the whole platform, was another component to take care of, and an extra machine to take into account when deploying the platform.

    This administrator node used Salt to set up and maintain the Kubernetes cluster among the different nodes comprising your cluster.

    During this time, your feedback has been that a little more flexibility on the deployment was appreciated, so you could experiment with slightly different setups, even if they were for proof of concepts while you were fleshing out the details of production clusters.

  • Kubernetes Rolling Update Strategy in our production infra

    Kubernetes rolling update strategy means suppose we are running pod (containers) in our live infra and we want to update new changes into our running pod like build update, confrontational changes etc. While deployment new pod with new changes suppose our containers got stuck or failed due to any reason.

    So, we have to redeploy old pod with old changes again to avoid downtime of our application. This complete process is called rolling update strategy in Kubernetes.

    Kubernetes rolling update strategy

    Before moving to next we should aware about new pod deployment strategy of Kubernetes means how many new pods it will deploy at a time without taking downtime. Because high availability of our website is our first priority. So, while deploying new pod Kubernetes will deploy 25% or you can say one fourth of the total pod. Suppose we are running four pods first it will terminate 25% of total pod means one pod. Then it will launch 25% new pod and so on.

  • Tackle OpenStack networking woes with SUSE OpenStack Cloud Crowbar

    By far, the most difficult aspect of successfully deploying OpenStack is getting the networking right, a challenge that has caused many a well-intentioned IT team to throw up its hands and toss in the towel. Fortunately, SUSE OpenStack Cloud removes much of that pain by automating most of the network deployment and dramatically simplifying custom network set-ups.

  • Grow your virtualization environments without breaking the bank

    An IT director at a large financial services company shares the benefits and cost reductions they’ve experienced by switching to Red Hat Virtualization. In just three years, it’s paved the way for an efficient, stable and cost-effective virtualization environment.

  • How to Handle OpenShift Worker Nodes Resources in Overcommitted State

    One of the benefits in adopting a system like OpenShift is facilitating burstable and scalable workload. Horizontal application scaling involves adding or removing instances of an application to match demand. When OpenShift schedules a Pod, it’s important that the nodes have enough resources to actually run it. If a user schedules a large application (in the form of Pod) on a node with limited resources , it is possible for the node to run out of memory or CPU resources and for things to stop working!

    It’s also possible for applications to take up more resources than they should. This could be caused by a team spinning up more replicas than they need to artificially decrease latency or simply because of a configuration change that causes a program to go out of control and try to use 100% of the available CPU resources. Regardless of whether the issue is caused by a bad developer, bad code, or bad luck, what’s important is how a cluster administrator can manage and maintain control of the resources.

    In this blog, let’s take a look at how you can solve these problems using best practices.

  • How the new Quarkus extension for Visual Studio Code improves the development experience

    Earlier this year, we were introduced to Quarkus, the next-generation, container-first framework for Java applications. As expected, such new frameworks and technologies make way for new developer tools focused on making the development experience even better.

    The recent Quarkus extension for Visual Studio Code release aims to do just that, by bringing features specific to Quarkus project development within VS Code. The new VS Code extension is dependent on a couple of Java extensions for VS Code, so it is recommended that you have the Java Extension Pack installed. This article outlines what the Quarkus extension for VS Code has to offer: convenient features for an already convenient Java framework.

  • OpenShift Commons Gathering in Milan 2019 – Recap [Slides]

    On September 18th, 2019, the first OpenShift Commons Gathering Milan brought together over 300 experts to discuss container technologies, operators, the operator framework and the open source software projects that support the OpenShift ecosystem. This was the first OpenShift Commons Gathering to take place in Italy.

    The standing room only event hosted 11 talks in a whirlwind day of discussions. Of particular interest to the community was Christian Glombek’s presentation updating the status and roadmap for OKD4 and CoreOS.

    Highlights from the Gathering induled an OpenShift 4 Roadmap Update, customer stories from Amadeus, the leading travel technology company, and local stories from Poste Italiane and SIA S.p.A. In addition to the technical updates and customer talks, there was plenty of time to network during the breaks and enjoy the famous Italian coffee.

  • Powering the hybrid cloud on next-generation hardware: Red Hat Enterprise Linux on IBM System Z and LinuxONE

    For more than five years we have been driving our technology strategy around the idea that the future of enterprise IT does not reside solely in an enterprise datacenter or in the public cloud. Instead the next wave of computing is built on a blend of these technologies and infrastructure: in short, the future is hybrid. The value of hybrid clouds comes from the choice it delivers, pairing the control of the corporate datacenter alongside the scale and flexibility of public clouds. We strongly feel, however, that the most valuable hybrid clouds are those that offer not only a choice of deployment type and location, but also a choice of the underlying architecture and the capacity to run on multiple public clouds.

    [....]

    With RHEL available on Z15 and LinuxONE III, this helps pave the way for the rest of Red Hat’s hybrid cloud portfolio, including Red Hat OpenShift, to emerge on IBM enterprise platforms. We’re pleased to continue our work with IBM in bringing the world’s leading enterprise Linux platform to their next-generation systems.

To follow along, Burr created an accompanying GitHub repository, so you too can learn how to setup an awesome Kubernetes cluster in just 9 steps.

  • Weaveworks Named a Top Kubernetes Contributor

    But anyone who knows the history of Weaveworks might not be too surprised by this. Weaveworks has been a major champion of Kubernetes since the very beginning. It might not be too much of a coincidence that Weaveworks was incorporated only a few weeks after Kubernetes was open sourced, five years ago. In addition to this, the very first elected chair of the CNCF’s Technical Oversight Committee, responsible for technical leadership to the Cloud Native Foundation was also headed up by our CEO, Alexis Richardson(@monadic) (soon to be replaced by the awesome Liz Rice (@lizrice) of Aqua Security).

  • Improving trust in the cloud with OpenStack and AMD SEV

    This post contains an exciting announcement, but first I need to provide some context!

    Ever heard that joke “the cloud is just someone else’s computer”?

    Of course it’s a gross over-simplification, but there’s more than a grain of truth in it. And that raises the question: if your applications are running in someone else’s data-centre, how can you trust that they’re not being snooped upon, or worse, invasively tampered with?

  • Attention: Fedora Yahoo Email Users

    Going from a blast of the past we are currently going through one of the Yahoo is not allowing many emails with either fedoraproject.org OR from our mail routers. It would seem that the way to get yahoo to blacklist a domain is to get subscribed to mailing lists and then report the lists as SPAM. Enough accounts (or maybe if one person does it enough times).. yahoo will helpfully blacklist the domain completely. [It then is usually a multi-month process of people explaining that no Fedora is not a spam site, hasn't been taken over by a spam site, or a bunch of other things which do happen so any mail admin is going to be wary on.]

  • Custom Grafana dashboards for Red Hat OpenShift Container Platform 4

    OpenShift administrators often face the same challenges as other system administrators: "I need a tool that will monitor the health of my system." Yet, traditional monitoring tools often fall short in their visibility of an OpenShift cluster. Thus, a typical OpenShift monitoring stack includes Prometheus for systems as well as service monitoring, and Grafana for analyzing and visualizing metrics.

    Often, administrators are looking to write custom queries and create custom dashboards in Grafana. However, the Grafana instance that is provided with the monitoring stack, along with its dashboards, is read-only. Enter the community-powered Grafana operator provided by OperatorHub.

  • IBM will soon launch a 53-qubit quantum computer
