  • Connecting and managing microservices with Istio 1.0 on Kubernetes

    Coming into this year, CoreOS’s Alex Polvi predicted that Istio, an open source tool to connect and manage microservices, would soon become a category leading service mesh (essentially a configurable infrastructure layer for microservices) for Kubernetes. Today we celebrate a milestone that brings us closer to that prediction: celebrating the general availability of Istio 1.0.

    Istio provides a method of integrating services like load balancing, mutual service-to-service authentication, transport layer encryption, and application telemetry requiring minimal (and in many cases no) changes to the code of individual services. This is in juxtaposition to other solutions like the various Java libraries from Netflix OSS. Utilizing these libraries requires both the use of Java for development as well as modification to source code, separately integrating these capabilities into each application component. I like to think of Istio as another component in your application stack, providing this functionality without extensive code changes.

  • Istio 1.0 Brings Service Mesh to Cloud Native Applications

    Istio disaggregates microservices networking connectivity, enabling services to be connected in a mesh. With Istio, service-to-service networking can be offloaded from individual microservices in a way that could help to expedite development. Kubernetes is a container orchestration system and has its own networking abstraction known as the Container Networking Interface (CNI) with policies defined via the Network Policy API. Istio can be deployed on top of an existing Kubernetes CNI deployment.

    "Just as Kubernetes provides orchestration of containers, Istio might best be viewed as providing orchestration of service-to-service networking yielding a much better way to develop and deploy microservice-based applications in a multicloud world," Lew Tucker, CTO for Cloud Computing at Cisco, wrote in a blog post.

  • Paving the way for intelligent and performance-sensitive applications on Kubernetes with Red Hat OpenShift Container Platform 3.10

    In November 2017, we highlighted our collaboration with key partners like NVIDIA in bringing performance-sensitive applications to Kubernetes and, ultimately, to Red Hat OpenShift. With today’s launch of Red Hat OpenShift Container Platform 3.10, we’re pleased to say that Red Hat’s enterprise Kubernetes platform is now well-positioned to handle several of these demanding workloads, offering a modern, fully open Kubernetes platform upon which to run next-generation applications.

  • Red Hat OpenShift Container Platform 3.10 is now available for download

    Today, we’re pleased to announce the general availability of Red Hat OpenShift Container Platform 3.10 (read the release notes; download the new version). Every release of OpenShift contains hundreds of fixes for enhanced security and performance, tested integrations throughout the stack, and access to hundreds of validated ISV solutions. For a full walkthrough of the latest updates, you can view our latest OpenShift Commons Briefing.

  • A Fedora COPR for libinput git master

    To make testing libinput git master easier, I set up a whot/libinput-git Fedora COPR yesterday. This repo gets the push triggers directly from GitLab so it will rebuild with whatever is currently on git master.

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.
