Red Hat and SUSE on CRI-O

  • Red Hat contributes CRI-O to the Cloud Native Computing Foundation

    Today CRI-O, a project started at Red Hat in 2016 to be an Open Container Initiative-based implementation of the Kubernetes Container Runtime Interface, is being contributed to the Cloud Native Computing Foundation (CNCF). This project joins cornerstone containers and Kubernetes projects we’ve been a part of like etcd and others to join a neutral home for stewardship.

    This is a step forward for the containers and CRI-O community because it brings the project into the same home as Kubernetes, which benefits users given its close interdependency. CRI-O and Kubernetes follow the same release cycle and deprecation policy.

    CRI-O already has a variety of maintainers outside of Red Hat including Intel and SUSE. Red Hat plans to continue participating in developing CRI-O, especially as a part of our enterprise Kubernetes product, Red Hat OpenShift. With our heritage and dedication to open source software and community-driven development, CRI-O can benefit the community even further within CNCF housed next to Kubernetes.

  • Welcome to the CNCF, CRI-O!

    CRI-O, the Open Container Initiative (OCI) implementation of the Kubernetes Container Runtime Interface (CRI), will join the Cloud Native Computing Foundation (CNCF) incubator today. The project provides an alternative container runtime for Kubernetes and was founded back in 2016 (originally known as OCID) with the introduction of the Kubernetes CRI. CRI-O focuses on its first principles of stability and reliability. This has been proven since one and a half year for now and CRI-O synchronizes its releases with Kubernetes to ensure these principles for the future, too. The projects popularity raised over the past years that it is now the best solution to run Kubernetes workloads in a secure fashion. Currently, CRI-O has worldwide 106 contributors and 9 maintainers coming from Intel, Red Hat, and SUSE. SUSE CaaS Platform version 3 provides it as a technology preview, where CRI-O can be chosen during the installation. No further workload changes are needed to switch from Docker or containerd to CRI-O.

Cloud Native Computing Foundation adopts Kubernetes-friendly...

  • Cloud Native Computing Foundation adopts Kubernetes-friendly container runtime

    A few years ago, Docker made containers popular. With the rise of Kubernetes container orchestration, Cloud Native Computing Foundation's (CNCF) newly adopted open-source Container Runtime Interface -- Orchestrator (CRI-O) runtime -- CRI-O may rise to the top of container deployments.

    That's because to run containers at scale you need an orchestration program. By the end of 2017, Kubernetes has become the most popular container orchestrator.

    You can, of course user Docker to run containers under Kubernetes. Indeed, Docker is still Kubernetes' default container runtime. But the lightweight CRI-O runtime works hand-in-API-glove with Kubernetes.

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.
