  • Operator pattern: REST API for Kubernetes and Red Hat OpenShift

    In this article, we will see a similar pattern when writing the REST API in any known framework vs. writing an Operator using Kubernetes’ client libraries. The idea behind this article is not to explain how to write a REST API, but instead to explain the internals of Kubernetes by working with an analogy.

  • Rust framework dev says ‘I’m done with Open Source’…has second thoughts

    The main developer behind a Rust actor framework pulled the code behind the project in apparent protest against an “unsafe sh*tstorm” against him last week.

    And while the coder in question now appears to have nominated new leadership to continue the project, the apparent “ragequit” has prompted questions about the dynamics within the open source community.

    [...]

    “You could notice after each unsafe shitstorm, I started to spend less and less time with the community,” he continued. “You felt betrayed after you put so much effort and then to hear all this sh*t comments, even if you understand that that is usual internet behavior. Anyway, removing issue was a stupid idea. But I was pissed off with last two personal comments, especially while sitting and thinking how to solve the problem. I am sorry for doing that.” [SIC]

  • A quick-and-dirty guide on how to install packages for Python

    When people start learning Python, they often will come across a package they want to try and it will usually start with "just pip install it!" The problem with that advice is it's a very simplistic view of how to manage packages and can actually lead to problems down the road. And while there is a tutorial on installing packages at packaging.python.org, it might be a bit intimidating for some if they are just looking to quickly get up and going.

    If you just want to start poking at Python and want to avoid the pitfalls to installing packages globally, it only takes 3 steps to do the right thing.

  • 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.
