  • OpenShift 4.5: Bringing developers joy with Kubernetes 1.18 and so much more

    Since the first Red Hat OpenShift release in 2015, Red Hat has put out numerous releases based on Kubernetes. Five years later, Kubernetes is celebrating its sixth birthday, and last month, we announced the general availability of Red Hat OpenShift Container Platform 4.5. In this article, I offer a high-level view of the latest OpenShift release and its technology and feature updates based on Kubernetes 1.18.

    Although OpenShift 4.5 brings many improvements by itself, many other Red Hat contributions enhance the developer experience with this release. Figure 1 shows the range of additional technology updates that improve the operational and development experience when using OpenShift 4.5.

  • iptables: The two variants and their relationship with nftables

    In Red Hat Enterprise Linux (RHEL) 8, the userspace utility program iptables has a close relationship to its successor, nftables. The association between the two utilities is subtle, which has led to confusion among Linux users and developers. In this article, I attempt to clarify the relationship between the two variants of iptables and its successor program, nftables.

  • Contribute at the Fedora Kernel and GNOME test days

    Fedora test days are events where anyone can help make sure changes in Fedora work well in an upcoming release. Fedora community members often participate, and the public is welcome at these events. If you’ve never contributed to Fedora before, this is a perfect way to get started.

    There are two upcoming test days in the upcoming week. The first, starts on Monday 17 August through Monday 24 August, is to test the Kernel 5.8. Wednesday August 19, the test day is focusing on testing GNOME. Come and test with us to make the upcoming Fedora 33 even better. Read more below on how to do it.

  • Red Hat OpenShift 4.5 Features New Virtualization and Edge Capabilities

    Red Hat has announced the general availability of Red Hat OpenShift 4.5.

    This release includes the new OpenShift Virtualization feature, which lets organizations “bring standard VM-based workloads to Kubernetes, helping eliminate the workflow and development silos that typically exist between traditional and cloud-native application stacks.” It also provides full-stack, “push-button” automation for VMware vSphere deployments.

    Red Hat announced additional new features to meet the needs of enterprise edge workloads, aiming to bring full Kubernetes functionality to the edge and “seamless management of edge sites across the hybrid cloud” through its new Advanced Cluster Management for Kubernetes.

  • IBM details next-gen POWER10 processor

    IBM on Monday took the wraps off its latest POWER RISC CPU family, optimized for enterprise hybrid-cloud computing and artificial intelligence (AI) inferencing, along with a number of other improvements.

    Power is the last of the Unix processors from the 1990s, when Sun Microsystems, HP, SGI, and IBM all had competing Unixes and RISC processors to go with them. Unix gave way to Linux and RISC gave way to x86, but IBM holds on.

  • 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.
