  • Red Hat: 5 lessons I learned about chaos engineering for Kubernetes | Opensource.com

    Kubernetes is a complex framework for a complex job. Managing several containers can be complicated, and managing hundreds and thousands of them is essentially just not humanly possible. Kubernetes makes highly available and highly scaled cloud applications a reality, and it usually does its job remarkably well. However, people don't tend to notice the days and months of success. Months and years of smooth operation aren't the things that result in phone calls at 2 AM. In IT, it's the failures that count. And unfortunately, failures don't run on a schedule.

  • Consuming Pino logs from Node.js applications

    Node.js offers a vast array of options to developers. This is why Red Hat and IBM teamed up to produce the Node.js reference architecture, a series of recommendations to help you build Node.js applications in the cloud. One of our recommendations is that you use Pino, an object logger for Node.js. You can visit this GitHub page for an overview of how and why to use Pino. This article demonstrates how to create and consume Pino logs with the Red Hat OpenShift Logging service.

  • Why automation progress stalls: 3 hidden culture challenges

    One of the major challenges to automation success exists right out in the open, even if people sometimes pretend otherwise. Automation stokes anxiety about how it will impact people’s jobs, including the possibility that it will make them obsolete.

    These automation obstacles might be lurking a bit outside your line of sight.
    We recently covered that most prominent issue with advice for IT leaders on proactively managing automation anxiety. But not every challenge is as visible.

    Here are three obstacles that might be lurking a bit outside your line of sight. Factor them into your planning and execution.

  • IT careers: 8 essential tips for your first 90 days | The Enterprisers Project

    You never get a second chance to make a first impression, as the saying goes. And while a misstep on the first day is understandable and surmountable, it's the first few months in a new role that tend to matter most. "First impressions are important in most situations in life," says Charley Betzig, managing director at technology executive search firm Heller Search Associates, "and this is no different when you start a new job."

    This is your time to "subtly and directly impress upon your subordinates, peers and managers that you are the right person for the job."

  • Download the original Red Hat Linux 0.9 "Halloween" release

    As a special Halloween treat this year we wanted to provide a download to Red Hat Linux 0.9 (beta). That 0.9 isn't a typo, that's the first publicly distributed release that got the entire Red Hat ball rolling.

    We talked about this release before on the Red Hat Blog, in a post in 2019. It was distributed with a spiral-bound book full of documentation and a single CD-ROM.

    After we wrote about the Halloween release in 2019, I got a number of pings on social media and via email asking for the files or an ISO image. For a variety of reasons, including a move, reconnecting with the ISO image took a little longer than one might hope. But, just in time for Halloween 2021, it has been relocated and is ready to go.

  • 3 basic Linux group management commands every sysadmin should know

    Groups make it easy to associate users with similar access-control requirements, so managing users and groups is a key responsibility for sysadmins. As I mentioned in my article on managing users, I like simple commands with a logical syntax. Such commands are easier to remember, particularly for new administrators.

  • GitOps: Best practices for the real world

    There is a common misunderstanding about how GitOps should be applied in real-world environments. Developers equate Infrastructure as Code (IaC) with GitOps in concept or believe that GitOps can only work with container-based applications — which is not true. In this blog, you will learn what GitOps is and how to apply its principles to real-world development and operations.

  • 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.
