  • Prevent auto-reboot during Argo CD sync with machine configs | Red Hat Developer

    Nodes in Red Hat OpenShift can be updated automatically through OpenShift's Machine Config Operator (MCO). A machine config is a custom resource that helps a cluster manage the complete life cycle of its nodes. When a machine config resource is created or updated in a cluster, the MCO picks up the update, performs the necessary changes to the selected nodes, and restarts the nodes gracefully by cordoning, draining, and rebooting them. The MCO handles everything ranging from the kernel to the kubelet.

    However, interactions between the MCO and the GitOps workflow can introduce major performance issues and other undesired behavior. This article shows how to make the MCO and the Argo CD GitOps orchestration tool work well together.

  • Exploring new opportunities in open source: From RHEL user to quality engineer

    Red Hat's Products and Technologies organization is doing game-changing work in the IT industry, so we're taking a closer look at some of the talented Red Hatters from around the world who are enabling our continued evolution. In showcasing their unique stories, it's clear that there's no one path to finding success as a Red Hatter. For each of us, it's about open collaboration and building something together.

    As a principal software quality engineer in Beijing, Red Hatter Shi Wei often sees how his role impacts the company. "Each year at Red Hat Summit, there are usually one or two presentations that are directly related to a project I’m working on, which makes me feel that my daily work is closely related to Red Hat’s success. It’s nice to feel like a part of that."

    Even before joining the company, Wei was a part of the open source community. "My Linux journey started with Red Hat. I clearly remember using my first Linux distribution—Red Hat Linux 9—for the first time. It really made an impact on my career path. In my previous position, I was an operations and maintenance engineer, working on Unix business support systems for a telecommunications provider. My whole career has been about Unix and Linux. So, when I joined Red Hat, I was excited to be a part of the team behind these products."

  • 8 ways to enjoy the holidays with your team

    When I first started my company, I didn’t know what I was getting myself into. I’d never built a startup or run a nonprofit before. But the pandemic had just begun, and I knew I needed to do something to help the 40 percent of Americans who couldn’t afford a $400 emergency long before COVID-19 further destroyed our social safety nets.

    So I reached out to my neighbors, my co-workers, and my friends of friends.

    A few weeks in, we secured a team of more than 30 passionate individuals who worked on nights and weekends building a functioning platform to help the people who needed it most. Everyone was remote, and everyone was a volunteer, so I learned quickly that building a community online was not only harder than doing so in an office, but that it was even more important.

    Community is what makes the late nights easier. It’s what helps us show up for each other on the tough days. And it’s what allows us to celebrate all of our wins, whether it’s a successful campaign or helping a neighbor, even from afar.

  • Digital transformation: 4 tips to speed your progress | The Enterprisers Project

    While digital transformation has been an IT industry priority for years, the pandemic accelerated the transition. Companies looked to run operations from anywhere and anytime, increase nimbleness, and build protection from disruption. Remote work and contactless retail transactions are two prime examples.

    While the operational impact of the pandemic is slowly waning, it’s clear that many attitudes and expectations have permanently shifted for both employees and customers. Shoppers, for example, now expect a seamless experience between online and in-store buying – and many prefer the convenience of curbside pickup. Employees have proven their ability to work and remain productive from anywhere and anytime with connected devices, applications, and connectivity.

    All of this means that the strong demand for digital transformation isn’t lessening. Organizations should be examining all aspects of their operations for opportunities to enact digital change that can unlock benefits for employees and deliver valuable interactions and experiences for their customers.

  • 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.
