  • Easier container security with entitlements

    During KubeCon + CloudNativeCon Europe 2018, Justin Cormack and Nassim Eddequiouaq presented a proposal to simplify the setting of security parameters for containerized applications. Containers depend on a large set of intricate security primitives that can have weird interactions. Because they are so hard to use, people often just turn the whole thing off. The goal of the proposal is to make those controls easier to understand and use; it is partly inspired by mobile apps on iOS and Android platforms, an idea that trickled back into Microsoft and Apple desktops. The time seems ripe to improve the field of container security, which is in desperate need of simpler controls.

  • Kubernetes, Four Years Later, and Amazon Redefining Container Orchestration

    Well, here we are. Kubernetes turns four years old this month—technically, on June 7, 2018—the very same platform that brings users and data center administrators scalable container technologies. Its popularity has skyrocketed since its initial introduction by Google. Celebrating the project’s birthday is not the only thing making the headlines today. Amazon recently announced the general availability of its Elastic Container Services for Kubernetes (EKS), accessible via Amazon Web Services (AWS).

    Once upon a time, it wasn’t a simple task to orchestrate and manage containers in the cloud. Up until this recent EKS announcement, it was up to the administrator to spin up a virtual machine through an Elastic Cloud Compute (EC2) service, run Kubernetes on top of a traditional Linux server installation in EC2 and rely on other AWS moving components to host the container image registry. The entire process was very involved. Not any more!

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
