  • What is the difference between a Linux container and an image? | Enable Sysadmin

    One of the problems with computer programming is that the same names are constantly used for different purposes. For example, the term namespace is used in many different ways. I often get confused when people talk about namespaces within Kubernetes. For example, some people hear the term and think of virtual clusters, but when I hear it, I think of the Linux namespaces used with pods and containers. Similarly, image can refer to a VM image, a container image, or an OCI image stored at a container registry.

  • Node.js serverless functions on Red Hat OpenShift, Part 2: Debugging locally | Red Hat Developer

    Welcome back to our series on using serverless functions on Red Hat OpenShift. The previous article introduced you to how logging works in Node.js and how to customize what is logged in a Node.js function application. Now, we'll take a look at how to debug Node.js function-based applications. Because debugging is a longer topic, we'll cover it in two parts. This article walks through how to set up and debug function applications locally with Visual Studio Code (VS Code). The next article will show you how to connect and debug function applications running in a container on a cluster.

    Note: For an introduction to logging function-based applications, see Node.js serverless functions on Red Hat OpenShift, Part 1: Logging. For an overview of Red Hat OpenShift Serverless Functions, see Create your first serverless function with Red Hat OpenShift Serverless Functions.

  • What is a hybrid work culture? 5 essentials

    Organizational culture ranks as an eternally important leadership issue. Ignore culture and you’re more likely to end up with negative outcomes: toxicity, inequitability, burnout, turnover, and so forth.

    Investing in a positive culture, on the other hand, is both healthy and good business.

    How do you foster a healthy hybrid work culture? First, fight the FUD.
    Organizational culture discussions took a different turn in 2020: How to foster a healthy one when everyone works remotely? In 2021, that question is shifting again for many companies: How do you foster a healthy hybrid work culture?

    Of course, it helps to know what “hybrid work” means, as we recently reported. Hybrid work entails some well-defined mix of on-site and remote work, say on specific days of the week or by specific teams. Given that basic framework, building and maintaining a positive organizational culture can be even more complex, as it needs to encompass the different dynamics of hybrid work models.

  • 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.
