  • Modernizing applications with Apache Camel, JavaScript, and Red Hat OpenShift | Red Hat Developer

    Apache Camel is used widely for message queue integration and notification. Its lightweight and simple coding structure makes it a good choice for developers. Camel is well suited for application modernization and integrates very well with Kubernetes and Red Hat OpenShift. You can use these technologies together for a continuous integration and continuous delivery (CI/CD) pipeline and deployment.

    In this article, we'll introduce the elements of application modernization, give an overview of Camel's components and architecture, and demonstrate how to use Camel with JavaScript to deploy your applications to OpenShift. We'll go through a few application modernization examples and look at the performance gains from using Camel with OpenShift and JavaScript. We'll also introduce Camel K, a lightweight integration framework built from Apache Camel that is specifically designed for serverless and microservices architectures.

  • 13 essential skills sysadmins need to make a career move into management

    Some of us have witnessed firsthand when a great technician turned into a manager as a reward from the company for faithful and fantastic work. It could be the aspiration of the technical person to turn manager. Still, other factors such as the salary headroom for a previous role have been reached—only manager roles get the desired perks of bonus, company car, better healthcare, etc.

    However, by removing one of the sharpest tools in the shed, the company is running a considerable risk. The transformation from a great sysadmin to a good manager does not happen without support, requiring a lot of changes. If the transition does not go well, the company will have lost one of its best sysadmins and instead gained one of its worst managers. To avoid this situation for a sysadmin that aspires to become a manager, I have gathered some valuable tips that perhaps can guide you on your path to become a manager or to get comfortable in the manager role you just obtained.

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.
