Do We Have More Kubernetes Distributions Than We Need?

Filed under
Server
OSS

Kubernetes itself—meaning the source code you can download from kubernetes.io—is not very useful on its own. Setting up a Kubernetes cluster using the source code would require you to compile the code and set up a server environment (or, in most cases, a cluster of servers) to host it, install it, configure it, set up tools to manage it and update it all on your own.

That’s a lot of work, and it’s not a realistic way for most people to use Kubernetes. That’s why a number of companies have created Kubernetes distributions. The distributions provide not just a preconfigured version of Kubernetes itself, but also other important tools for installing and working with Kubernetes. Many distributions also include host operating systems. Some even give you hosting infrastructure in the form of IaaS in a public cloud.

Kubernetes is not unique in spawning an ecosystem of distributions. The Linux kernel has done the same thing. So have other complex software platforms, inlcuding Spark, Hadoop and OpenStack.

Shuttleworth: OpenStack made mistakes

  • Shuttleworth: OpenStack made mistakes, but Kubernetes not a replacement

    Pity OpenStack. Celebrating its 10th birthday this coming October, the open-source cloud was conceived as the future: the open-alternative to Jeff Bezos’ proprietary behemoth.

    A decade on and despite success among telcos and internal IT departments, OpenStack is now being mentioned in the same breath as Kubernetes – just not in a good way.

    There’s a burgeoning discussion as to whether it’s possible to wire a serverless cloud using open-source containers instead of OpenStack.

  • Platform9 Launches Open Source Kubernetes Tools

    SaaS-managed hybrid cloud company Platform9 has launched Klusterkit – a set of three open source Kubernetes tools. With these tools, organizations can deploy and operate production-grade Kubernetes clusters in air-gapped, on-premises environments.

    The three tools – etcdadm, nodeadm and cctl – could be used independently or in tandem:

    Adopted by Kubernetes Cluster Lifecycle SIG, etcdadm is a kubeadm-like command-line interface (CLI) that simplifies the operation of etcd clusters.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
