  • Kubernetes-in-Kubernetes and the WEDOS PXE bootable server farm

    When you own two data centers, thousands of physical servers, virtual machines and hosting for hundreds of thousands sites, Kubernetes can actually simplify the management of all these things. As practice has shown, by using Kubernetes, you can declaratively describe and manage not only applications, but also the infrastructure itself. I work for the largest Czech hosting provider WEDOS Internet a.s and today I'll show you two of my projects — Kubernetes-in-Kubernetes and Kubefarm.

    With their help you can deploy a fully working Kubernetes cluster inside another Kubernetes using Helm in just a couple of commands. How and why?

    Let me introduce you to how our infrastructure works. All our physical servers can be divided into two groups: control-plane and compute nodes. Control plane nodes are usually set up manually, have a stable OS installed, and designed to run all cluster services including Kubernetes control-plane. The main task of these nodes is to ensure the smooth operation of the cluster itself. Compute nodes do not have any operating system installed by default, instead they are booting the OS image over the network directly from the control plane nodes. Their work is to carry out the workload.

  • Windows games on Linux: How to start games from the Epic Games Store - Market Research Telecast

    You don’t look in the mouth of a given horse: Epic Games’ strategy of expanding its user base with free games is having an effect even on many die-hard Linux gamers. A good 150 games have already gathered in this way in the author’s Epic Games account.

    In many cases, the collected games can also be played under Linux with the help of Wine, but a Linux version of the Epic Games Launcher is not in sight. Open source tools such as Heroic Games Launcher, Legendary or Lutris fill the gap. With the help of the compatibility layer Wine (or its Fork Proton), the tools pretend Windows games to have a suitable operating system environment.

    Lutris brings many different platforms from GOG to Steam to retro emulators under one roof, but it is quite complex). Heroic Games Launcher and the underlying command line tool Legendary, on the other hand, have specialized in making Epic Games’ games run across platforms – on Linux, macOS and Windows.

  • How to Install MariaDB 10.6 on CentOS 8 Stream - LinuxCapable

    MariaDB is one of the most popular open-source databases next to its originator MySQL. The original creators of MySQL developed MariaDB in response to fears that MySQL would suddenly become a paid service due to Oracle acquiring it in 2010. With its history of doing similar tactics, the developers behind MariaDB have promised to keep it open source and free from such fears as what has happened to MySQL.

    MariaDB has become just as popular as MySQL with developers, with advanced clustering with Galera Cluster 4, faster cache/indexes, storage engines, and features/extensions that you won’t find in MySQL.

  • 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.
