When you don't rely on a Linux distribution in the container, you have a lot of control, which means you can customize everything for your needs. Great article, this will be reference for me next time I need to explain the value of the OS with containers. Install Windows Terminal (optional). The opinions expressed on this website are those of each author, not of the author's employer or of Red Hat. This is a best-of-breed model, and it's valid in certain use cases. Red Hat and the Red Hat logo are trademarks of Red Hat, Inc., registered in the United States and other countries. Get the highlights in your inbox every week. The common point of all linux distributions, and why they are called linux, is because they all use the linux kernel. They offer working container engines and container runtimes out of the box, so you can just fire up your containers and let somebody else worry about making things work. It uses the host system’s kernel directly and, as a consequence, can not be run on non-Linux machines. They o… See Building, Running and Managing Containers for more information on the container tools available on the distribution. Windows Subsystem for Linux (WSL) 2 introduces a significant architectural change as it is a full Linux kernel built by Microsoft, allowing Linux containers to run natively without emulation. The knowledge that maintainers have is tremendous and leveraged so much without really being appreciated. Deepak was also the technical reviewer for the Course Technology PTR book Ruby Programming for the Absolute Beginner. We should be asking questions like: How will these choices affect maintenance six months down the road? Container Linux, normally known as CoreOS is a pioneer in the business of container-based Linux distributions.It is an extremely lightweight Linux operating system designed for clustered deployments providing automation, security, … Let’s look at the factors that govern the choice of a host OS, as well as the Linux to run within a Docker container. Jump to main content. This will almost always make your container images larger than building from scratch. Stop reading and send your nearest package maintainer (again, hail the maintainers!) Slackware and Gentoo (I still have a soft spot in my heart) taught us that. Sleep mode stopped working right, my docking station stopped working right, and there were numerous other small, random errors. But others, such as Windows containers, are huge. You already know this, but Linux distributions are the solution. So, why do Linux distributions compile kernels and all the packages together? Traditional distros package unused software that leads to dependency conflicts and needlessly increases the attack surface. Another disadvantage is you will not always have access to the latest upstream code. An OS that is small yet provides the essential functionality would be the best choice. Linux containers Menu Close menu. Alpine Linux is a super lightweight Linux distribution that's useful for Docker containers.. To understand the problem, we have to investigate why we started using Linux distributions in the first place. The adoption of containers has made the problem even worse because it's even further abstracted. As a package maintainer myself for quite a few distibutions, (Alpine, Gentoo, and Openwrt to name a few), I use containers as a part of my development workflow. This will provide the best experience, including the ability to code and debug inside a remote Docker container and connected to your Linux distribution. The adoption of containers has made the problem even worse because it's even further abstracted. This is more knowledge than any single developer or sysadmin is ever going to reasonably learn and retain. Submit changes to these docs via GitHub. That's par for the course for the industry - it just moves from one fad to the next. The base operating system, or container operating system, is the OS that runs within a container. Built from the ground up and designed primarily for the modern data centre, Container Linux provides specialist tools for making the system secure, reliable and up-to-date. Compiling kernels is actually fairly easy. Got it, let that sink in. Instead? "It appears we are considering and making technology decisions based more on fashion sense and immediate emotional gratification than thinking through the secondary effects of our choices." This flavor of Linux was purpose-built for container deployments at cloud-level scale. Containers share the same kernel as the host, that's why you can run an Arch image on a Ubuntu host. Ubuntu made minimal Docker images available on Docker Hub so that Ubuntu is more suitable as a base OS for Docker images, in addition to being one of the most suitable host OS for Docker. Debian provides some variants with a slimmer base, such as buster-slim and 10.3-slim. The kernel is special. I appreciate the work you do, even though I am a "container guy.". Review: The best Linux distros for Docker and containers Over the past six months I have reviewed five minimal Linux distributions that are optimized for running containers: Alpine Linux, CoreOS Container Linux, RancherOS, Red Hat Atomic Host, and VMware Photon OS. Deepak is a Sun Certified Java Programmer and Web Component Developer, and has worked in the fields of XML, Java programming and Java EE for ten years. Download and install the Linux kernel update package. The best answers lie at the intersection of application requirements and OS functionality. Clear Linux supports seamless integration of Kata Containers for any OS version above 23380. This is especially useful for embedded development. Let's double-click on that a bit. It's the core of a Linux operating system, and it's the first thing we rely on when a system boots. For more discussion on open source and the role of the CIO in the enterprise, join us at The EnterprisersProject.com. Opensource.com aspires to publish all content under a Creative Commons license but may not be able to do so in all cases. In the Linux operating system, unlike with virtual machines, each Docker container does not use a complete operating system kernel; multiple Docker containers can share the same one. In earlier CoreOS supported only Dockers platform but recently … Most OS images are lightweight, with minimal compute resource requirements. Flatcar Container Linux is an immutable Linux distribution for containers. A second choice to make is for the Linux distribution to run within a Docker container. Alpine Linux is small, simple, and secure, and with its quick boot-up time, it is designed specifically for platforms such as Docker containers. Embarrassingly (because I have worked with containers for the last five years), I must admit that I have compiled kernels quite recently. Booting a Linux system without a compiled kernel is a bit of a challenge. You are responsible for ensuring that you have the necessary permission to reuse any work on this site. Finally, we do all of the maintainers (hail the maintainers!) Built using components from the Red Hat side of the Linux universe, this operating system was one of the earlier lightweight GNU/Linux distributions to appear with a focus on containers. I would group the reasons into two major buckets: kernels and other packages. Come on, that's kinda' fun, right? Because it’s tied to Red Hat, it supports Red Hat-friendly container components of the container stack, such as Kubernetes. This can be frustrating for developers, especially when you just want to get something out the door, but not as frustrating as being paged to look at a library you haven't thought about in three years that the upstream maintainers have been changing the whole time. Scott is a social media... 6 open source tools for staying organized. What matters is that without the developers and maintainers, and coders out there who have dedicated most of their lives to "The Kernel"?....I'd be writing this reply on an Dell Latitude E4300 running Windows 10, but slow as molasses, and with constant freezes. Container Linux (formerly CoreOS) is a Linux-based operating system for servers. 5. If we forget that engineering is a zero-sum game with measurable tradeoffs—advantages and disadvantages, with costs and benefits of different approaches— we do ourselves a disservice, we do our employers a disservice, and we do our colleagues who will eventually maintain our code a disservice. Alternative approaches, like distroless and scratch containers, seem to be all the rage. a disservice by not appreciating the work they do. This makes it easy to run a few commands at install and rely on the subject matter expertise embedded in the Linux distribution. 1. I had to get nested KVM working on RHEL 7 so that I could run OpenShift on OpenStack virtual machines, in a KVM virtual machine on my laptop, as well as our Container Development Kit (CDK). Deepak is also the author of the Packt Publishing books JDBC 4.0 and Oracle JDeveloper for J2EE Development, Processing XML Documents with Oracle JDeveloper 11g, EJB 3.0 Database Persistence with Oracle Fusion Middleware 11g, and Java EE Development in Eclipse IDE. With standardized interfaces like Gnome and KDE, there is no need to be a devotee of any distribution. Well, today I have a brand-new distro that I’d like to introduce you to, called Super Container OS, and targeted at developers who want to run containerized apps. Unlike the Linux kernel and Glibc, these types of libraries change with very little regard to breaking API compatibility. Due to your country's anti-spam laws, we are unable to give you access to this content, unless you agree to receive communications from TechWell, 841 Prudential Drive | 12th Floor | Jacksonville, FL | 32207, A Docker image that makes use of the slimmer edition would have a. instruction such as the following at the beginning of the Dockerfile: Ditch Your Logs for Better Monitoring Metrics, Less than 50% the size of a standard server image, Up to 40% faster boot-up time than a standard server image. I will be writing this same article again, probably about Kubernetes, in about seven to 10 years. Without thoughtful preparation, the size a… With container hosts, a Linux distribution offers you access to a wide hardware ecosystem, ranging from tiny ARM systems, to giant 128 CPU x86 boxes, to cloud-provider VMs. A second choice to make is for the Linux distribution to run within a Docker container. Containers have also helped me work with projects that are developed on systems that I don't use, i.e., Ubuntu, or Fedora, as I can run instances of each without ever having to learn how to maintain those systems. With container hosts, a Linux distribution offers you access to a wide hardware ecosystem, ranging from tiny ARM systems, to giant 128 CPU x86 boxes, to cloud-provider VMs. So, given the above mentioned two, containers for Gnome and KDE are the next step. First, let's talk about kernels. linuxcontainers.org is the umbrella project behind LXC, LXD and LXCFS. And, of course, I had missed some things. Getting started. Container Linux redefines the operating system as a smaller, more compact Linux distribution. While the kernel and associated system software can be tricky to compile, the much, much bigger problem from a workload perspective is compiling thousands and thousands of packages to give us a useable Linux system. Welcome to the life of a sysadmin. Your time is coming too, when you will be in maintenance mode, overused, and underappreciated. Like any good sysadmin, I was a little worried that I missed some important configuration options and patches. Home; LXC. Our main focus is system containers. Gentoo: Gentoo Gentoo Linux is a versatile and fast, completely free Linux meta-distribution geared towards developers and network professionals. You are in control, so you choose when to spend the engineering work to incorporate new software. The base operating system, or container operating system, is the OS that runs within a container. Luckily, with containers, you can roll back and shave the yaks the next business day, but it will still eat into your time for delivering new value to the business, new features to your applications. In this Docker and Alpine Linux tutorial, we'll build an Nginx web server that demonstrates how small a Docker container image can be. Working closely with engineering teams, at both a product and upstream project level, he combines personal experience with customer and partner feedback to enhance and tailor strategic container features and capabilities. Focus areas includes container runtimes, tools, and images. Multiple Docker containers run in isolation on top of Docker Engine, which runs on the underlying host operating system. Think of it as a middle ground between a chroot and full virtualization technologies such as VirtualBox, KVM or Xen. Gentoo taught us this in a visceral way, which turned everyone into a miniature distribution maintainer. Starting with WSL2, Docker can run in it’s full flow in Windows and you can use images built for Linux. On the other hand, the tremendous amount of development and runtime software that needs to be packaged for a usable Linux system can be daunting. The kernel is a part of the operating system that handles communication with the hardware. Another advantage is you have access to the latest packages. Basically, Linux distributions do a ton of work to save you time—on a regular Linux system or with containers. Ubuntu is derived off Debian OS, which is another common choice for the host OS. It is a friendly fork of CoreOS Container Linux and as such, compatible with it. Simple: to make sure things work together. Building from a base image is not perfect; there are disadvantages, like the size of all the dependencies that get dragged in. Scratch builds have the advantage of being really small. https://www.redhat.com/en/topics/containers/whats-a-linux-container For more in-depth support, jump into #coreos on IRC, email the dev list or file a bug. Linux Containers (LXC) are a lightweight virtualization technology and they have various uses. The best Linux distros offer the easiest and simplest way to use Linux, though a lot depends on whether you're a beginner or advanced user. What are the engineering tradeoffs? That's Linux without a Linux distribution. Note. What features found in “full” Linux distros are missing from these minimal operating systems — and does it matter to your application? CoreOS/Container Linux. That means that three years from now your patching event likely becomes a code-changing event, not a yum update event. So, thank you to all of the maintainers in Fedora, RHEL (Frantisek, you are my hero), Debian, Gentoo, and every other Linux distribution. Bodhi Linux is one such lightweight Linux distribution that is specially designed to run on hardware with limited capabilities. With these types of programs, every container build is a compile event. The goal is to offer a distro and vendor neutral environment for the development of Linux container technologies. It relies on a ton of work done by package maintainers in a Linux distribution. On Red Hat Enterprise Linux (RHEL) 8, Docker is no longer a supported container runtime. Each container has its own file system and networking. Install Visual Studio Code (optional). I can spin up different distributions as needed for porting new packages all from the same host. Some people say Linux distributions no longer matter with containers. Application code relies on a lot of libraries ranging from JSON munging libraries to object-relational mappers. Linux is still the backbone of it all, and therefore should be given proper reverence, whether you use it at home or not, or strictly for work is not relevant. Bottlerocket: AWS's New Linux Distro for Containers Christine Hall | Sep 11, 2020 On the surface, Amazon Web Service's new minified operating system to use in containers is just another bare-bones Linux distribution to go alongside others that serve the same purpose, such as Red Hat Enterprise Linux CoreOS, RancherOS, or Flatcar Container Linux. But it did work well enough for a live demo of OpenShift on OpenStack, in a single KVM virtual machine on my laptop. So you're absolutely right! Enable WSL, install a Linux distribution, and update to WSL 2. Furthermore, the only way you can ensure that millions of permutations of packages can be installed and work together is by using the old paradigm: compile it and ship it together as a thing (i.e., a Linux distribution). Every problem I described applies to your container host (kernel and system software) and container image (system software and all other packages)—notice the overlap; there are compilers, C libraries, interpreters, and JVMs in the container image, too. The set of skills necessary for the thousands of different pieces of software you might use is daunting for any single person. Linux containers do not require a base OS, but if software is to be run in a container, a base OS becomes essential. Container Linux is a lightweight Linux Distro which is designed for clusters and server. The point is that you have to build everything together to ensure it works together with any sane level of reliability, and it takes a ton of knowledge to build a usable cohort of packages. One of the questions that often arises is which Linux distribution to use as the host operating system. Container Linux by CoreOS is an open source software project that provides system administrators and experienced users with a modern and minimal operating system designed for massive server deployments. The Minimal Ubuntu images do not include documentation, editors, locales, or other user-oriented features of standard Ubuntu Server images, and they provide the following benefits: A Minimal Ubuntu image could be made a base OS image with the Dockerfile instruction: Another Docker image commonly used as the base OS image is “alpine,” which is a minimal Docker image based on Alpine Linux, with a complete index for a large selection of packages and a size of only 5 MB. From the other side of the equation, what are the advantages to basing applications on distributions stripped to the bare minimum? an e-card (wait, did I just give my age away?). I look at it this way: regardless of whether or not you're a container-"maintainer" or not? Introduction; News; Getting started The Linux distribution that runs within a container could be the same or different from the host Linux. Each package requires subject matter expertise. I'm writing it on a Lenovo ThinkPad T-410 which struggles to run Windows even more than the Dell did....that's running PoP_OS and making my dream of not having to upgrade every other year to another laptop a reality! You don't have to wait for a Linux distro to update anything. Infrastructure for container projects. One of the most common choices is Ubuntu, as it provides the latest kernels with the latest capabilities. OK, that said, there are times that building from scratch makes sense. Kubernetes, Istio, Prometheus, and Knative: I am looking at you. There are tradeoffs to building from scratch and building from base images. At Red Hat, Scott McCarty is technical product manager for the container subsystem team, which enables key product capabilities in OpenShift Container Platform and Red Hat Enterprise Linux. The Linux distribution that runs within a container could be the same or different from the host Linux. Seriously though, these people do a ton of work, and it's really underappreciated. The knowledge that maintainers have is tremendous and leveraged so much without really being appreciated. You will need to give this folder extra permissions to allow Docker to use the images from it. Deepak is the co-author of the Apress book Pro XML Development with Java Technology and was the technical reviewer for the O'Reilly book WebLogic: The Definitive Guide. Choosing a Container Operating System. For container images, Linux distributions offer you easy access to a ton of software for your projects. Get the latest stories delivered to your inbox every week. It's frustrating to watch. How does this paradigm shift affect our build systems at scale? Flatcar Container Linux is a self-updating operating system designed for containers, making it ideal for running Kubernetes and other container platforms. A Docker image that makes use of the slimmer edition would have a FROM instruction such as the following at the beginning of the Dockerfile: The slimmer versions do not include some features and files that are unnecessary for running software within containers—for example, a "slim" Docker image wouldn't include documentation files. Here's an overview of Linux. But, if you want a usable system with the ability to try new software whenever you want, you have to learn how to compile and install the new software before you can even begin to learn to use it. An operating system that provides a kernel optimized for sharing among multiple containers would be the most suitable. Basically, Linux distributions do a ton of work to save you time—on a regular Linux system or with containers. Often, updating to new libraries with new features drags in unwanted API changes, which means fixing incompatibilities in code (in other words, shaving yaks). Containers came into being as collections of minimal functions brought together to create a complete application. If you are a web developer and rolling your eyes at me, I have one word for you: DevOps. It appears we are considering and making technology decisions based more on fashion sense and immediate emotional gratification than thinking through the secondary effects of our choices. Linux containers (LXC) offers a nominal operating system environment that can be used to run specific Linux applications or network services. First, create two directories: Create C:\lcow, which will be used as scratch space for Docker while preparing the containers.. Also create C:\Program Files\Linux Containers.This is where the Ubuntu container image will live. A secondary problem in this bucket is that system software, like compilers, C libraries, and interpreters, must be tuned for the options you built into the kernel. Remember, there is a cost to controlling everything. The base operating system, or container operating system, is the OS that runs within a container. We just need a true distro that provides: workspace/officeSpace/gamer interfaces. Kernels have a lot of different configuration options when they're being compiled that can have a tremendous effect on how hardware and software run on one. Choosing a Container Operating System. This security distro is getting popular nowadays because it’s easy to deploy, manage, and run containers. It also has the advantage that a patching event six months—or even 10 years—from now (with RHEL) is an operations/systems administrator event (yum update), not a developer event (that requires picking through code to figure out why some function argument no longer works). For games or game containers, its likely that Android will be the winner. Project ACRN is a flexible, lightweight reference hypervisor built with real-time and safety-criticality in mind, optimized to streamline embedded development through an open source project. A second choice to make is for the Linux distribution to run within a Docker container. #justsayin Suffice to say, I fired RHEL7 up on a brand new 4.X kernel at the time. Building from base images has the advantage that most build operations are nothing more than a package install or update. That means you are carrying a pager, my friend. The host operating system kernel manages lower-level functions such as memory management, file system, networking, and process scheduling. Prepare the container environment. You still have to worry about API breakage three years from now, but if you are a Golang shop, you should have the skillset to fix things over time. Deepak is a Docker Mentor and has published 5 books on Docker and Kubernetes. Container Linux and its investment in container-optimized Linux and automated “over the air” software updates are complementary to Red Hat Enterprise Linux, Red Hat Enterprise Linux Atomic Host and Red Hat’s integrated container runtime and platform management capabilities. Some pieces of software require running only three commands: ./configure, make, and make install. Developers, you are getting paged at 2 AM if the security team can't find a firewall hack to block the exploit. The ubi-init image is configured out of the box to run systemd in the container when run. The Linux distribution that runs within a container could be the same or different from the host Linux. Others require a lot of subject matter expertise ranging from adding users and configuring specific defaults in etc to running post-install scripts and adding systemd unit files. Leverage the speed & security Kata Containers provide with the performance Clear Linux delivers. I will completely concede that statically compiled Golang programs and C programs are two decent candidates for scratch/distroless builds. But I digress…. Unlike other distros, Gentoo Linux has an advanced, source-based package management system called Portage. It is part of the Linux kernel, and can let you emulate one, or multiple Linux distros on a single Linux host. Shaving yaks at 2 AM when the application doesn't work is not fun. Now, let's talk about all the other packages. Even when you build from scratch, you will likely look at how a package maintainer built and shipped things—a good artist is a good thief—so, don't undervalue this work. That's the engineering problem you are agreeing to when you forgo a Linux distribution.
