  • Customer success stories: DevOps at scale

    Digital transformation doesn’t stop at just one product or solution. As your organization takes steps towards modernizing IT infrastructure, it’s worth thinking about the processes and people components as well. Sometimes it’s as much organizational transformation as it is digital.

    Team processes like DevOps to support continuous software releases can help you innovate faster. (We’ll show you how in an Open Innovation Lab.) Whether you’re exploring how to upgrade your legacy environment or adding to the Red Hat enterprise open source solutions you already have, our expert team can guide you on connecting your technology, culture, and processes together.

  • Why you need to use Kubernetes schema validation tools | Opensource.com

    How do you ensure the stability of your Kubernetes (K8s) clusters? How do you know that your manifests are syntactically valid? Are you sure you don't have any invalid data types? Are any mandatory fields missing?

    Most often, we become aware of these misconfigurations only at the worst time: when we're trying to deploy the new manifests.

    Specialized tools and a "shift-left" approach make it possible to verify a Kubernetes schema before it's applied to a cluster. This article addresses how you can avoid misconfigurations and which tools are the best to use.

  • 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.
