Filed under
Server
OSS

At DockerCon 17 in April, Docker Inc made a series of large announcements, including a shift to a new model with the Moby Project to build the Docker Engine. Now in June, the first major release of Docker built with the Moby Project is available in the form of the Docker 17.06 Community Edition release.

The Moby Project is a refactoring of how Docker as a container platform is built, by breaking it down into aDocker series of community-focused efforts that includes LinuxKit and containerd among others.

What is Docker? Linux containers explained

Filed under
Linux
Server

Like FreeBSD Jails and Solaris Zones, Linux containers are self-contained execution environments—with their own, isolated CPU, memory, block I/O, and network resources—that share the kernel of the host operating system. The result is something that feels like a virtual machine, but sheds all the weight and startup overhead of a guest operating system.

In a large-scale system, running VMs would mean you are probably running many duplicate instances of the same OS and many redundant boot volumes. Because containers are more streamlined and lightweight compared to VMs, you may be able to run six to eight times as many containers as VMs on the same hardware.

When Amazon moved into brick and mortar with its Whole Foods purchase, many people assumed the battle between Amazon and Walmart for your retail dollar would move to the streets of America. The conflict will be fought there with drones, self-driving delivery trucks, and no-touch stores, but it will also be fought in Amazon's stronghold: The cloud.

While everyone knows about Amazon Web Services (AWS) cloud, Walmart hasn't been neglecting the cloud either. Years ago, Walmart invested in the OpenStack cloud.

  • Building Images with Dockerfile and Docker Hub

    In this series previewing the self-paced Containers for Developers and Quality Assurance (LFS254) training course from The Linux Foundation, we’ve covered installing Docker, introduced Docker Machine, and some basic commands for performing Docker container and image operations. In the three sample videos below, we’ll take a look at Dockerfiles and Docker Hub.

    Docker can build an image by reading the build instructions from a file that’s generally referred to as Dockerfile. So, first, check your connectivity with the “dockerhost” and then create a folder called nginx. In that folder, we have created a file called dockerfile and in the dockerfile, we have used different instructions, like FROM, RUN, EXPOSE, and CMD.

  • What can developers learn from being on call?

    We often talk about being on call as being a bad thing. For example, the night before I wrote this my phone woke me up in the middle of the night because something went wrong on a computer. That’s no fun! I was grumpy.

    In this post, though, we’re going to talk about what you can learn from being on call and how it can make you a better software engineer!. And to learn from being on call you don’t necessarily need to get woken up in the middle of the night. By “being on call”, here, I mean “being responsible for your code when it breaks”. It could mean waking up to issues that happened overnight and needing to fix them during your workday!

  • Making the Internet Archive’s full text search faster.

    The Internet Archive is a nonprofit digital library based in San Francisco. It provides free public access to collections of digitized materials, including websites, books, documents, papers, newspapers, music, video and software.

    This article describes how we made the full-text organic search faster — without scaling horizontally — allowing our users to search in just a few seconds across our collection of 35 million documents containing books, magazine, newspapers, scientific papers, patents and much more.

  • DevOps: More Than Automation

    Type “devops” into any job search site today and the overwhelming majority of results will be for some variation of “DevOps Engineer”. The skills required will centre on tools like Puppet/Chef/Ansible, AWS/Azure, scripting in Python/Perl/Bash/PowerShell etc. Essentially, they’ve taken a deployment automation engineer role, crossed out “deployment automation” and written “DevOps” in its place.

The What, Why and Wow! Behind the CoreOS Container Linux

Filed under
OS
Linux
Server

Unlike most Linux distributions, CoreOS doesn’t have a package manager. Instead it takes a page from Google’s ChromeOS and automates software updates to ensure better security and reliability of machines and containers running on clusters. Both operating system updates and security patches are regularly pushed to CoreOS Container Linux machines without sysadmin intervention.

You control how often patches are pushed using CoreUpdate, with its web-based interface. This enables you to control when your machines update, and how quickly an update is rolled out across your cluster.

Linux owns supercomputing

Filed under
GNU
Linux
Server

The US is falling behind in the supercomputer race, but no matter where a supercomputer is running, one thing remains true: It's running Linux.

In the latest Top500 Supercomputer competition, which was revealed in June 2017, 498 out of 500 supercomputers were running Linux. Of the remaining two, both ran Unix.

These were a pair of Chinese IBM POWER computers running AIX near the bottom of the list. These machines came in at 493 and 494. Since the November 2016 Top500, these supercomputers have dropped by over 100 places. At this rate, Linux will score a clean sweep in the next biannual Top500 competition.

When the first Top500 supercomputer list was compiled in June 1993, Linux was barely more than a toy and hadn't adopted Tux as its mascot yet. Starting in 1998, when it first appeared on the Top500, Linux quickly dominated supercomputing.

  • Why Infrakit & LinuxKit are better together for Building Immutable Infrastructure?

    Let us accept the fact – “Managing Docker on different Infrastructure is still difficult and not portable”. While working on Docker for Mac, AWS, GCP & Azure, Docker Team realized the need for a standard way to create and manage infrastructure state that was portable across any type of infrastructure, from different cloud providers to on-prem. One serious challenge is that each vendor has differentiated IP invested in how they handle certain aspects of their cloud infrastructure. It is not enough to just provision n-number of servers;what IT ops teams need is a simple and consistent way to declare the number of servers, what size they should be, and what sort of base software configuration is required. Also, in the case of server failures (especially unplanned), that sudden change needs to be reconciled against the desired state to ensure that any required servers are re-provisioned with the necessary configuration. Docker Team introduced and open sourced “InfraKit” last year to solve these problems and to provide the ability to create a self healing infrastructure for distributed systems.

    The board is designed for HPC workload environments requiring parallel computing processing performance. Up to 72 cores for optional support and 100Gb/s node interconnect. Six slots for DDR4, 2400Mhz registered ECC DIMMS to achieve a capacity of 384G.

  • [Older] DNS Infrastructure at GitHub

    At GitHub we recently revamped how we do DNS from the ground up. This included both how we interact with external DNS providers and how we serve records internally to our hosts. To do this, we had to design and build a new DNS infrastructure that could scale with GitHub’s growth and across many data centers.

  • ServiceMaster polishes DevOps process for Linux container security

    ServiceMaster Global Holdings Inc., which owns consumer brands such as Terminix, Merry Maids, Furniture Medic and ServiceMaster Clean and Restore, deploys 75,000 service trucks to residential driveways each day. Five years ago, the company was taken private by an equity firm, and new leadership, including a new CIO, was brought in to modernize its operations. When it returned to the public market in 2014, the company had completely overhauled its approach to IT.

  • My Love Affair with Synology

    In my "Hodge Podge" article in the October 2016 issue, I mentioned how much I love the Synology NAS I have in my server closet (Figure 1). I got quite a few email messages from people—some wanting more information, some scolding me for not rolling my own NAS, and some asking me what on earth I need with that much storage. Oddly, the Linux-running Synology NAS has become one of my main server machines, and it does far more than just store data. Because so many people wanted more information, I figured I'd share some of the cool things I do with my Synology.

  • Certified Ubuntu Cloud Guest – The best of Ubuntu on the best clouds

    Ubuntu has a long history in the cloud. It is the number one guest operating system on AWS, Azure and Google Cloud Platform. In fact there are more Ubuntu images running in the public cloud than all other operating systems combined.

    Ubuntu is a free operating system which means anyone can download an image, whenever they want. So why should cloud providers offer certified Ubuntu images to their customers?

  • Cloud Foundry and Kubernetes: Different Tools

    It’s difficult to compare programming languages and platforms, of course, but this was the analogy that most frequently came to mind last week. Cloud Foundry is unlikely to be as popular as it was shortly after it launched, when it was the only open source PaaS platform available. But this says little about Cloud Foundry, and more about the platform market which – like every other infrastructure market – is exploding with choice to the point of being problematic. It also ignores the ability for the Cloud Foundry foundation to actively embrace this choice via the addition of Kubo.

  • Cloud Native Apps and Security: The Case for CoreOS Rkt and Xen

    CoreOS's rkt started at the beginning of 2014 as a security-focused alternative to Docker. The project aimed to create a signature verification of cloud-native apps by default; the intention was to guarantee the integrity of the apps. It also stepped away from the central-daemon design of Docker, which requires root privileges for all operations. By contrast, the rkt process is short-lived, limiting the chances of being exploited, and some of rkt commands can be executed as unprivileged user.

  • U.S. Slips in New Top500 Supercomputer Ranking

    Tapwrit was the second favorite at Belmont, and Sunway TaihuLight was the clear pick for the number-one position on TOP500 list, it having enjoyed that first-place ranking since June of 2016 when it beat out another Chinese supercomputer, Tianhe-2. The TaihuLight, capable of some 93 petaflops in this year’s benchmark tests, was designed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and is located at the National Supercomputing Center in Wuxi, China. Tianhe-2, capable of almost 34 petaflops, was developed by China’s National University of Defense Technology (NUDT), is deployed at the National Supercomputer Center in Guangzho, and still enjoys the number-two position on the list.

  • Linux vs. Windows Server OS Comparison [Ed: Worst article I saw today. A few characters cannot sum up the amount of nonsense in it.]
  • The evolution of scalable microservices

    Today’s enterprise applications are deployed to everything from mobile devices to cloud-based clusters running thousands of multi-core processors. Users have come to expect millisecond response times and close to 100% uptime. And by “user” I mean both humans and machines. Traditional architectures, tools and products simply won’t cut it anymore. To paraphrase Henry Ford’s classic quote: we can’t make the horse any faster, we need cars for where we are going.

SUSE release Container-as-a-Service Platform

Unless you've been living under an SCO UnixWare server you know that Docker, and other container technologies, are taking over IT. SUSE, the major European Linux company, also saw this coming, so it's releasing its all-in-one Linux and container platform: SUSE Container-as-a-Service (CaaS) Platform.

SUSE's not the first to try this approach. CoreOS Container Linux gets that honor. But CaaS is providing a solid SUSE Enterprise Linux Server (SLES)-based container platform for modern enterprises turning to containers for their IT needs.

  • Steps toward a privacy-preserving phone
    What kind of cell phone would emerge from a concerted effort to design privacy in from the beginning, using free software as much as possible? Some answers are provided by a crowdfunding campaign launched in August by Purism SPC, which has used two such campaigns successfully in the past to build a business around secure laptops. The Librem 5, with a five-inch screen and radio chip for communicating with cell phone companies, represents Purism's hope to bring the same privacy-enhancing vision to the mobile space, which is much more demanding in its threats, technology components, and user experience. The abuse of mobile phone data has become a matter of worldwide concern. The capture and sale of personal data by apps is so notorious that it has been covered in USA Today; concerns over snooping contribute to the appeal of WhatsApp (which has topped 1.3 billion users) and other encrypted and privacy-conscious apps. But apps are only one attack vector. I got in touch with Todd Weaver, founder and CEO of Purism, to find out what the company is doing to plug the leaks in mobile devices.

  • DockerCon EU 17 Panel Debates Docker Container Security
    There are many different security capabilities that are part of the Docker container platform, and there are a number of vendors providing container security offerings. At the DockerCon EU 17 conference in Copenhagen, Denmark, eWEEK moderated a panel of leading vendors—Docker, Hewlett Packard Enterprise, Aqua Security, Twistlock and StackRox—to discuss the state of the market. To date, there have been no publicly disclosed data breaches attributed to container usage or flaws. However, that doesn't mean that organizations using containers have not been attacked. In fact, Wei Lien Dang, product manager at StackRox, said one of his firm's financial services customers did have a container-related security incident.
