  • Blueprint for a team with a DevOps mindset

    I've had the privilege to work with some of the brightest minds and leaders in my 33 years of software engineering. I've also been fortunate to work for a manager who made me question my career daily and systematically broke down my passion—like a destructive fire sucking the oxygen out of a sealed space. It was an unnerving period, but once I broke free, I realized I had the opportunity to reflect on one of the greatest anti-patterns for effective teams.

    It should come as no surprise that the culture of an organization and its engineering teams is the greatest challenge when embarking on a DevOps mindset transformation. The organization needs to influence through leadership and autonomy, promoting a culture of learning and experimentation, where failure is an opportunity to innovate, not persecute. Fear of retribution should be frowned upon like the archaic Indian practice of Sati. Teams need to feel they are operating in a safe environment, understand what the transformation entails, and know how they will be affected.

  • 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.
