  • Kubernetes Graduates CNCF Incubator, Debuts New Sandbox

    Though the Kubernetes container orchestration system has been widely deployed at scale in production around the world, it wasn't until March 6 that the project graduated from the Cloud Native Computing Foundation's (CNCF) incubator.

    The CNCF's process brings projects in as incubated projects and then aims to move them through to graduation, which implies a level of process and technology maturity. Kubernetes was the founding project for the CNCF, which was launched back in July 2015.

    Google contributed Kubernetes to the CNCF in an effort to help build a more diverse community of contributors and to spur adoption.

  • Kubernetes Ingress: NodePort, Load Balancers, and Ingress Controllers

    A fundamental requirement for cloud applications is some way to expose that application to your end users. This article will introduce the three general strategies in Kubernetes for exposing your application to your end users, and cover the various tradeoffs of each approach. I’ll then explore some of the more sophisticated requirements of an ingress strategy. Finally, I’ll give some guidelines on how to pick your Kubernetes ingress strategy.

  • Aqua Expands Container Security Platform With MicroEnforcer

    Aqua Security launched version 3.0 of its namesake container security platform on March 7, refocusing the product on providing Kubernetes cloud-native enterprise security controls.

    Aqua originally focused on just Docker container deployments, but with the new 3.0 update it is providing a series of capabilities that are aligned with Kubernetes deployments. Kubernetes provides container orchestration capabilities and has also been embraced by Docker Inc., which now also integrates Kubernetes as an option for its users.

    Looking beyond just Kubernetes, Aqua 3.0 also has a new capability called the MicroEnforcer, which is aimed at emerging forms of lightweight container deployments, such as the AWS Fargate service.

  • You got your VM in my container

    Containers and Kubernetes have been widely promoted as "disruptive" technologies that will replace everything that preceded them, most notably virtual machine (VM) management platforms such as vSphere and OpenStack. Instead, as with most platform innovations, Kubernetes is more often used to add a layer to (or complement) VMs. In this article, and in a presentation at SCALE16x, we'll be exploring two relatively new projects that aim to assist users in combining Kubernetes with virtualization: KubeVirt and Kata Containers.

    Most organizations still have large existing investments in applications that run on virtualized hosts, infrastructure that runs them, and tools to manage them. We can envision this being true for a long time to come, just as remnants of previous generations of technology remain in place now. Additionally, VM technology still offers a level of isolation that container-enablement features, like user namespaces, have yet to meet. However, those same organizations want the ease-of-use, scalability, and developer appeal of Kubernetes, as well as a way to gradually transition from virtualized workloads to containerized ones.

openSUSE Tumbleweed Is Now Powered by Linux Kernel 4.17, KDE Plasma 5.13 Landed

As of today, the openSUSE Tumbleweed rolling operating system is now powered by the latest and most advanced Linux 4.17 kernel series, which landed in the most recent snapshot released earlier. Tumbleweed snapshot 20180615 was released today, June 17, 2018, and it comes only two days after snapshot 20180613, which added the Mesa 18.1.1 graphics stack and KDE Plasma 5.13 desktop environment, along with many components of the latest KDE Applications 18.04.2 software suite. Today's snapshot 20180615 continued upgrading the KDE Applications software suite to version 18.04.2, but it also upgraded the kernel from Linux 4.16.12 to Linux 4.17.1. As such, OpenSuSE Tumbleweed is now officially powered by Linux kernel 4.17, so upgrading your installs as soon as possible would be a good idea. Read more

OSS Leftovers

  • Using Open Source Software in a SecDevOps Environment
    On 21 June 2018 the Open Source Software3 Institute is hosting a discussion that should be of high interest to enterprise technologists in the DC/Northern Virginia, Maryland area. From their invite: Come hear from our panelists about how the worlds of Open Source Software and the Secure Development / Operations (SecDevOps) intersect and strengthen one another. SecDevOps seeks to embed security in the development process as deeply as DevOps has done with operations, and Open Source Software is a major factor in Security, Development, and Operations. Tickets are free, but you need to register soon because seating is limited.
  • TenFourFox FPR8b1 available
    TenFourFox Feature Parity Release 8 beta 1 is now available (downloads, release notes, hashes). There is much less in this release than I wanted because of a family member in the hospital and several technical roadblocks. Of note, I've officially abandoned CSS grid again after an extensive testing period due to the fact that we would need substantial work to get a functional implementation, and a partially functional implementation is worse than none at all (in the latter case, we simply gracefully degrade into block-level divs). I also was not able to finish the HTML input date picker implementation, though I've managed to still get a fair amount completed of it, and I'll keep working on that for FPR9. The good news is, once the date picker is done, the time picker will use nearly exactly the same internal plumbing and can just be patterned off it in the same way. Unlike Firefox's implementation, as I've previously mentioned our version uses native OS X controls instead of XUL, which also makes it faster. That said, it is a ghastly hack on the Cocoa widget side and required some tricky programming on 10.4 which will be the subject of a later blog post.
  • GNU dbm 1.15
    GDBM tries to detect inconsistencies in input database files as early as possible. When an inconcistency is detected, a helpful diagnostics is returned and the database is marked as needing recovery. From this moment on, any GDBM function trying to access the database will immediately return error code (instead of eventually segfaulting as previous versions did). In order to reconstruct the database and return it to healthy state, the gdbm_recover function should be used.

  • Five Supercomputers That Aren't Supercomputers
    A supercomputer, of course, isn't really a "computer." It's not one giant processor sitting atop an even larger motherboard. Instead, it's a network of thousands of computers tied together to form a single whole, dedicated to a singular set of tasks. They tend to be really fast, but according to the folks at the International Supercomputing Conference, speed is not a prerequisite for being a supercomputer. But speed does help them process tons of data quickly to help solve some of the world's most pressing problems. Summit, for example, is already booked for things such as cancer research; energy research, to model a fusion reactor and its magnetically confined plasma tohasten commercial development of fusion energy; and medical research using AI, centering around identifying patterns in the function and evolution of human proteins and cellular systems to increase understanding of Alzheimer’s, heart disease, or addiction, and to inform the drug discovery process.
  • Office 365 is suffering widespread borkage across Blighty
     

    Some users are complaining that O365 is "completely unusable" with others are reporting a noticeable slowdown, whinging that it's taking 30 minutes to send and receive emails.
