Red Hat: Containers and Kubernetes, Systemd Everywhere, AMQ Streams on OpenShift and System Administrators

  • Containers and Kubernetes can be essential to a hybrid cloud computing strategy

    Hybrid cloud is gaining ground among enterprises that want to expand computing resources with public cloud infrastructure while still using their on-premise, data center environments. Adding public cloud can mean more elasticity, scalability, and even faster time to market. But if you want to improve the chances that your hybrid cloud can deliver on its promise, you need to think about adding containers to the mix.

    Linux containers provide a way to encapsulate application code in a way that makes the code more portable and faster to deploy. More and more organizations are using containers as part of the infrastructure for microservices-based, cloud-native applications.

    Containers can be portable across environments such as Red Hat OpenShift Container Platform and consistent, so they can speed application delivery times and make it easier for teams to collaborate, even if those teams are working in different deployment environments. And they can serve as a bridge between your data center and public cloud environments.

  • Systemd-homed Looks Like It Will Merged Soon For systemd 245

    Announced back in September at the All Systems Go event in Berlin was systemd-homed as a new effort to improve home directory handling. Systemd-homed wants to make it easier to migrate home directories, ensure all user data is self-contained, unify user-password and encryption handling, and provide other modern takes on home/user directory functionality. That code is expected to soon land in systemd.

    Systemd-homed was talked about by Lennart as being ready for versions 244 or 245. Now that systemd 244 shipped at the end of November, systemd-homed is looking like it will soon land in Git.

  • Understanding Red Hat AMQ Streams components for OpenShift and Kubernetes: Part 3

    In the previous articles in this series, we first covered the basics of Red Hat AMQ Streams on OpenShift and then showed how to set up Kafka Connect, a Kafka Bridge, and Kafka Mirror Maker.

  • What personality trait most defines a sysadmin?

    When you think of a system administrator, who do you think of?

    Chances are, most of us have taken a Myers-Briggs Type Indicator (MBTI) test at some point in our careers. For me, my results typically come up as INTJ, and I've always thought the traits associated with that type (introversion, intuition, thinking, judging) have aligned with my interest in technology and the kind of work I enjoy.

    But that doesn't mean that those are the only characteristics that make a good sysadmin. Far from it. A successful team is made up of a diversity of skills, viewpoints, and personal characteristics.

  • How to identify a strong sysadmin job applicant

    When a company looks for new resources with skills in a specific focus area—especially in IT—the challenge is on. Why? Because only a few in the company, if any, have even a vague notion of how to verify the skills they are looking for. The work of a system administrator is a key function, and if it goes wrong, the very existence of the company is at stake (something I’ve been unfortunate to witness when called in on an emergency rescue effort).

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.
