These 3 things are trying to kill Linux containers

Filed under
Linux
Server

For nearly two years, Linux containers have dominated the world of enterprise IT, and for good reason — among others, they take on issues that virtualization simply cannot within application development and computing at scale and allow for the enterprise world to truly embrace concepts like devops and microservices (the Service Oriented Architecture dream from years gone by). That sound you hear is IT vendors stampeding towards the container bandwagon, but, as with every emerging tech trend, this isn’t always a good thing, as not everyone is walking the walk, regardless of what the business might actually say.

  • SCO v. IBM: Judge Rules for IBM in Interferance Claims

    Two SCO stories in a week? As Yogi Berra would say, it’s 2003 all over again. But this time with a big difference. It’s almost over.

    I told you on Monday that Judge David Nuffer with the US District Court in Utah had shot down SCO’s attempts to bring an action for Unfair Competition against IBM because the issue is already covered by another breach of contract claim by SCO. On Tuesday, Judge Nuffer issued a ruling on a pair of interference claims which effectively takes whatever winds were left out of SCO’s sails.

    Bankrupt SCO, of course, lost their big $1 billion case against IBM long ago when Novell, in a separate case, proved that it, and not SCO, owned the copyrights that SCO was suing over. But SCO’s been struggling to stay alive, hoping to at least win a few bucks from IBM as compensation for all it went through.

  • Linux, IBM Share Bold Vision for Hyperledger Project, a Blockchain Fabric for Business

    No longer a group of thinkers and entrepreneurs on the fringe, the proponents of blockchain technology are growing in number, boosted by new attention from the media, financial institutions, professional services firms and, most recently, major tech giants.

    The development comes amid reports that the blockchain market could expand to account for more business in the coming years, with Aite Group projecting it could be worth as much as $400m in annual business by 2019.

    However, how this market takes shape, and which technology providers start to generate actual revenue, is less clear given the variety of new projects arising – from consortiums composed of financial institutions to open-source collaborations. What's more, each of these groups boasts a who’s-who list of well-known backers.

Docker Has No Plans to Ditch Ubuntu in Favor of Alpine Linux - Report

  • Docker as a High-Performance Enabler for Cloud Storage

    The container-based service Docker is gaining massive momentum in the industry, and for many good reasons. The current appeal of Docker stems from issues associated with running VMs, namely that each one has to be provided with virtualized memory and storage resources. Containers make it far easier to run enterprise-grade services and address concerns for data portability, scaling, processing, performance, extensibility and latency.

  • Is Docker ditching Ubuntu Linux? Confusion reigns

    Docker has long relied on Ubuntu Linux as the default host environment for Docker apps, but comments from the company's CTO recently suggest that might not be the case much longer.

    "We have hired Natanael Copa, the awesome creator of Alpine Linux, and are in the process of switching the Docker official image library from Ubuntu to Alpine," a user named shykes wrote in a Hacker News thread 10 days ago.

  • Unikernels, Docker, and Why You Should Care

    Docker's recent acquisition of Unikernel Systems has sent pulses racing in the microservice world. At the same time, many people have no clue what to make of it, so here's a quick explanation of why this move is a good thing.

    Although you may not be involved in building or maintaining microservice-based software, you certainly use it. Many popular Web sites and services are powered by microservices, such as Netflix, eBay and PayPal. Microservice architectures lend themselves to cloud computing and "scale on demand", so you're sure to see more of it in the future.

  • Docker gets minimalist with plan to migrate images to Alpine Linux

    Rumor has it that Docker Inc., the company behind Docker containers, is planning to switch from Ubuntu to the lightweight Alpine Linux OS as the host environment for Docker images.

Docker Images Are Moving From Ubuntu To Alpine Linux

Filed under
GNU
Linux
Server

Docker is reportedly going to be migrating all of their official images from an Ubuntu base to now using Alpine Linux.

Alpine Linux is the lightweight distribution built atop musl libc and BusyBox while using a GrSecurity-enhanced Linux kernel. Alpine Linux uses OpenRC as its init system. If you are unfamiliar with this "Small. Simple. Secure." distribution, you can learn more via AlpineLinux.org. The image for Alpine is a mere 5MB.

CoreOS Launches Docker Rival Rkt 1.0

Filed under
OS
Server

CoreOS released today rkt (pronounced Rock-it) 1.0, providing container users with an alternative runtime to Docker. CoreOS first announced rkt in December 2014 after dissatisfaction arose with the state of the Docker runtime.

While rkt is a competitor to the Docker runtime, users will still be able to run application containers that have been built with Docker tools. The promise of rkt is that of improved performance and security controls, as well as integration with CoreOS' larger platform effort Tectonic, which provides orchestration.

    In the past, the parent company Bittorrent Inc. has relied on an ad-based revenue model to keep uTorrent up and running, but now they have realized the need for a premium experience for the users by charging a nominal amount. Until now, bundled software that hides inside the uTorrent installation package has only consumed space on your computer. The development team is well aware of this issue and that’s why they have come up with the ad-free uTorrent.

Kernel Space: Linux, Graphics

  • Linux kernel bug delivers corrupt TCP/IP data to Mesos, Kubernetes, Docker containers
    The Linux Kernel has a bug that causes containers that use veth devices for network routing (such as Docker on IPv6, Kubernetes, Google Container Engine, and Mesos) to not check TCP checksums. This results in applications incorrectly receiving corrupt data in a number of situations, such as with bad networking hardware. The bug dates back at least three years and is present in kernels as far back as we’ve tested. Our patch has been reviewed and accepted into the kernel, and is currently being backported to -stable releases back to 3.14 in different distributions (such as Suse, and Canonical). If you use containers in your setup, I recommend you apply this patch or deploy a kernel with this patch when it becomes available. Note: Docker’s default NAT networking is not affected and, in practice, Google Container Engine is likely protected from hardware errors by its virtualized network.
  • Performance problems
    Just over a year ago I implemented an optimization to the SPI core code in Linux that avoids some needless context switches to a worker thread in the main data path that most clients use. This was really nice, it was simple to do but saved a bunch of work for most drivers using SPI and made things noticeably faster. The code got merged in v4.0 and that was that, I kept on kicking a few more ideas for optimizations in this area around but that was that until the past month.
  • Compute Shader Code Begins Landing For Gallium3D
    Samuel Pitoiset began pushing his Gallium3D Mesa state tracker changes this morning for supporting compute shaders via the GL_ARB_compute_shader extension. Before getting too excited, the hardware drivers haven't yet implemented the support. It was back in December that core Mesa received its treatment for compute shader support and came with Intel's i965 driver implementing CS.
  • Libav Finally Lands VDPAU Support For Accelerated HEVC Decoding
    While FFmpeg has offered hardware-accelerated HEVC decoding using NVIDIA's VDPAU API since last summer, this support for the FFmpeg-forked libav landed just today. In June was when FFmpeg added support to its libavcodec for handling HEVC/H.265 video decoding via NVIDIA's Video Decode and Presentation API for Unix interface. Around that same time, developer Philip Langdale who had done the FFmpeg patch, also submitted the patch for Libav for decoding HEVC content through VDPAU where supported.

Unixstickers, Linux goes to Washington, Why Linux?

  • Unixstickers sent me a package!
    There's an old, popular saying, beware geeks bearing gifts. But in this case, I was pleased to see an email in my inbox, from unixstickers.com, asking me if I was interested in reviewing their products. I said ye, and a quick few days later, there was a surprise courier-delivered envelope waiting for me in the post. Coincidentally - or not - the whole thing happened close enough to the 2015 end-of-the-year holidays to classify as poetic justice. On a slightly more serious note, Unixstickers is a company shipping T-shirts, hoodies, mugs, posters, pins, and stickers to UNIX and Linux aficionados worldwide. Having been identified one and acquired on the company's PR radar, I am now doing a first-of-a-kind Dedoimedo non-technical technical review of merchandise related to our favorite software. So not sure how it's gonna work out, but let's see.

In a blog post Jim Zemlin, the executive director of the Linux Foundation said, “In the proposal, the White House announced collaboration with The Linux Foundation’s Core Infrastructure Initiative (CII) to better secure Internet 'utilities' such as open-source software, protocols and standards.”
  • Why Linux?
    Linux may inspire you to think of coders hunched over their desks (that are littered with Mountain Dew cans) while looking at lines of codes, faintly lit by the yellow glow of old CRT monitors. Maybe Linux sounds like some kind of a wild cat and you have never heard the term before. Maybe you have use it every day. It is an operating system loved by a few and misrepresented to many.
