CoreOS vs Ubuntu: What are the differences?

Key differences between CoreOS and Ubuntu

CoreOS and Ubuntu are two popular operating systems used in the world of containerization and virtualization. While both systems offer similar functionalities, there are distinct differences that set them apart. Let's explore these differences:

  1. Package Management: One major difference between CoreOS and Ubuntu is their method of package management. CoreOS uses a minimalistic package manager called "Container Linux" that focuses on providing only the necessary components for running containers. On the other hand, Ubuntu uses the widely-used Advanced Package Tool (APT) for package management, providing a broader range of software packages.

  2. Update and Rollback Management: CoreOS is known for its automatic and seamless system update mechanism. It uses a concept called "Container Linux Update Operator" that enables automatic updates without requiring manual intervention. Ubuntu, while also providing automatic updates, may require manual intervention during the update process. Additionally, CoreOS boasts a built-in rollback mechanism, allowing users to easily revert to a previous system state in case of issues, whereas Ubuntu lacks this feature.

  3. Focus on Containerization: CoreOS is designed from the ground up with a strong focus on containerization technologies and container orchestration platforms like Kubernetes. It provides out-of-the-box compatibility with container runtimes like Docker and rkt, making it a preferred choice for container deployments. Ubuntu, while also capable of running containers, has a broader usage scope beyond just containerization.

  4. System Architecture: Another key difference lies in the underlying system architecture. CoreOS follows a minimalist approach, providing a lightweight and stripped-down operating system optimized for container workloads. Ubuntu, on the other hand, offers a full-fledged operating system with a comparatively larger footprint in terms of disk space and RAM usage.

  5. Community and Support: Ubuntu enjoys a larger and more well-established community, offering extensive support and a wealth of documentation. This makes it easier for users to find assistance and resources. While CoreOS also has a community and support system in place, it may not be as extensive or widely known as Ubuntu's.

In summary, CoreOS and Ubuntu differ in package management, update and rollback management, focus on containerization, system architecture, and community support. These differences make each operating system suitable for specific use cases and requirements.

Ubuntu always let people do what they want to do, it pushes its users to know what they are doing, what they want and helps them learn what they ignore.

Ubuntu is simple, works out-of-the-box after installation and has a incredibly huge community behind.

Ubuntu is lightweight and open, in the way, that the user has access to free AND efficient applications (most of the time, without ads) and, even if learning its folder structure is challenging, once done, you are really able to call yourself "someone who knows what is in your computer".

Windows, in comparison, is heavy, tends to make decision for you and always enable tracking application by default. grr

It has a simple user interface, of course, but on the stability point of view, it is hard to compete with something simpler (even with less features).

Personal preference : I prefer something simple that works 99% of the time, than a full-featured auto-magical system that works 50% of the time (and ask if the good version of the driver is really installed...)

Coming from a Debian-based Linux background, using the Ubuntu base image for my Docker containers was a natural choice. However, the overhead, even on the impressively-slimmed Hub images, was hard to justify. Seeking to create images that were "just right" in size, without unused packages or dependencies, I made the switch to Alpine.

Alpine's modified BusyBox has a surprising amount of functionality, and the package repository contains plenty of muslc-safe versions of commonly-used packages. It's been a valuable exercise in doing more with less, and, as Alpine is keen to point out, an image with fewer packages makes for a more sustainable environment with a smaller attack surface.

My only regret is that Alpine's documentation leaves a lot to be desired.

Ubuntu is much more faster over Windows and helps to get software and other utilities easier and within a short span of time compared to Windows.

Ubuntu helps to get robustness and resiliency over Windows. Ubuntu runs faster than Windows on every computer that I have ever tested. LibreOffice (Ubuntu's default office suite) runs much faster than Microsoft Office on every computer that I have ever tested.

CentOSCentOS

Global familiarity, free, widely used, and as a debian distro feels more comfortable when rapidly switching between local macOS and remote command lines.

CentOS does boast quite a few security/stability improvements, however as a RHEL-based distro, differs quite significantly in the command line and suffers from slightly less frequent package updates. (Could be a good or bad thing depending on your use-case and if it is public facing)

At the moment of the decision, my desktop was the primary place I did work. Due to this, I can't have it blow up on me while I work. While Arch is interesting and powerful, Ubuntu offers (at least for me) a lot more stability and lets me focus on other things than maintaining my own OS installation.

What is CoreOS?

It is designed for security, consistency, and reliability. Instead of installing packages via yum or apt, it uses Linux containers to manage your services at a higher level of abstraction. A single service's code and all dependencies are packaged within a container that can be run on one or many machines.

What is Ubuntu?

Ubuntu is an ancient African word meaning ‘humanity to others’. It also means ‘I am what I am because of who we all are’. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers.

What are some alternatives to CoreOS and Ubuntu?
Docker
The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere
LinuxKit
LinuxKit, a toolkit for building custom minimal, immutable Linux distributions. Designed for building and running clustered applications, including but not limited to container orchestration such as Docker or Kubernetes.
Rancher
Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.
Docker Swarm
Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
Mesosphere
Mesosphere offers a layer of software that organizes your machines, VMs, and cloud instances and lets applications draw from a single pool of intelligently- and dynamically-allocated resources, increasing efficiency and reducing operational complexity.
