  • Red Hat Learning Community fosters open source tech education and reaches 10k members

    We are pleased to announce that the Red Hat Learning Community has reached more than 10,000 members! Since its launch in September 2018, the community has shown itself to be a valuable hub for those seeking to share knowledge and build their open source skill set.

    When we first started out, this was just an idea. We set out to support, enable, and motivate new and experienced open source learners as they learn how to work with Red Hat technologies, validate their technical skill sets, build careers and pursue Red Hat Certifications. We soft launched the community in July 2018 and invited 400 Red Hat Training instructors, students, curriculum developers and certifications team members to jump-start community discussion boards and earn a founding member badge.

  • skuba Dives into Open Source Waters

    SUSE CaaS Platform 4, our next major release is now in beta. It has major architectural improvements for our customers. In the process of planning and developing it, we took a close look at bootstrapping clusters and managing node membership, and we listened to our customers. One of the things we heard from many of them was that they wanted a way to deploy multiple clusters efficiently, by scripting the bootstrap process or by integrating it into other management tools they use.
    To address this, we committed even more strongly to our upstream participation in Kubernetes development. Instead of building SUSE-specific tools as we had in earlier versions, we contributed the efforts of SUSE engineers to the upstream kubeadm component, helping it bridge the gap between its current state and the abilities we had previously implemented in the Velum web interface. Our bootstrap and node management strategy in version 4 is built on kubeadm.

  • 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.
