  • Why Operators are essential for Kubernetes

    As a solutions architect, I spend a lot of my time talking to my customers about Kubernetes. In every one of those conversations, it’s guaranteed that the topic of Kubernetes Operators will come up. Operators, and their relationship to Red Hat OpenShift, aren't always clear to those who are just starting out on their container adoption journey.

    Kubernetes has allowed the deployment and management of distributed applications to be heavily automated. A lot of that automation comes out of the box but Kubernetes wasn’t designed to know about all application types. So sometimes it’s necessary to extend the understanding of a specific type of application that Kubernetes has. Otherwise you have to manage a large part of these applications manually that ultimately defeats the purpose of deploying on Kubernetes. Operators allow you to capture how you can write code to automate a task beyond what Kubernetes itself provides.

    This post assumes you know what Kubernetes is and how it works and have some knowledge of OpenShift. So what are Operators and why are they so important in explaining what Red Hat OpenShift is?

  • MontaVista Joins the Rocky Enterprise Software Foundation as a Principal Sponsor

    MontaVista Software has today joined the Rocky Enterprise Software Foundation as a Principal Sponsor, endorsing the Rocky Linux distribution as an alternative solution to the CentOS Linux project as a Red Hat Enterprise Linux compatible solution. MontaVista will continue providing the MVShield program services for Long term support of both CentOS Linux and Rocky Linux baselines.

  • In the enterprise, Kubernetes has to play by the same rules as other platforms

    Without a doubt, Kubernetes is the most important thing that has happened in enterprise computing in the past two decades, rivalling the transformation that swept over the datacenter with server virtualization, first in the early 2000s on RISC/Unix platforms and then during the Great Recession when commercial-grade server virtualization became available on X86 platforms at precisely the moment it was most needed.

    All things being equal, the industry would have probably preferred to go straight to containers, which are lighter weight than server virtualization and which are designed explicitly for service-oriented architectures – now called microservices – but it is the same idea of chopping code into smaller chunks so it can be maintained, extended, or replaced piecemeal.

    This is precisely why Google spent so much time in the middle 2000s creating what are now seen as relatively rudimentary Linux containers and the Borg cluster and container controllers. Seven years ago, as it was unclear what the future platform might look like; OpenStack, which came out of NASA and Rackspace Hosting, was a contender, and so was Mesos, which came out of Twitter, but Kubernetes, inspired by Borg and adopting a universal container format derived from Docker, has won.

  • Three Tenancy Models For Kubernetes

    Kubernetes clusters are typically used by several teams in an organization. In other cases, Kubernetes may be used to deliver applications to end users requiring segmentation and isolation of resources across users from different organizations. Secure sharing of Kubernetes control plane and worker node resources allows maximizing productivity and saving costs in both cases.

    The Kubernetes Multi-Tenancy Working Group is chartered with defining tenancy models for Kubernetes and making it easier to operationalize tenancy related use cases. This blog post, from the working group members, describes three common tenancy models and introduces related working group projects.

    We will also be presenting on this content and discussing different use cases at our Kubecon EU 2021 panel session, Multi-tenancy vs. Multi-cluster: When Should you Use What?.

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.
