  • How to Install and Use Docker on Arch Linux

    If you are in the IT industry, chances are high that you must have heard of Docker, unless you live inside a cave or a remote region completely shut out from the rest of the world. Docker is an opensource containerization technology that has revolutionized how developers develop and deploy applications. It allows development teams to build, manage and deploy applications inside containers. A Container is a standalone prebuilt software package that packs with its own libraries and dependencies. Containers run in complete isolation of the host operating system and from each other as well.

    Docker offers immense benefits. Before containerization, developers used to encounter issues when writing and deploying code on various Linux flavors. An application would work perfectly well on one system only to fail on another system. Docker standardizes code deployment and ensures that the applications can run seamlessly across various computing environments without running into dependency issues or errors. Additionally, containers contribute to vast economies of scale. Docker is resource-friendly, lightweight, and quite efficient.

  • How to Limit Depth of ‘tree’ for Recursive File Listing

    Usually, the ls command is used in Linux to display files and folders. It is an inbuilt command in GNU/Linux. However, it has its shortcomings, for example, there is no option to view directories recursively.

    Today we want to introduce you to a new command called ‘tree’ which is used for recursive file listing, and how we can call it with a limit on the depth of file structure to be displayed.

  • A step-by-step guide to Knative eventing | Opensource.com

    In a previous article, I covered how to create a small app with Knative, which is an open source project that adds components to Kubernetes for deploying, running, and managing serverless, cloud-native applications. In this article, I'll explain Knative eventing, a way to create, send, and verify events in your cloud-native environment.

    Events can be generated from many sources in your environment, and they can be confusing to manage or define. Since Knative follows the CloudEvents specification, it allows you to have one common abstraction point for your environment, where the events are defined to one specification.

    This article explains how to install Knative eventing version 0.20.0 and create, trigger, and verify events. Because there are many steps involved, I suggest you look at my GitHub repo to walk through this article with the files.

  • 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.
