  • New container feature: Volatile overlay mounts

    Recent versions of Podman, Buildah, and CRI-O have started to take advantage of a new kernel feature, volatile overlay mounts. This feature allows you to mount an overlay file system with a flag that tells it not to sync to the disk.

    If you need a reminder about the use and benefits of overlay mounts, check out my article from last summer.

  • You need a hybrid cloud for digital transformation [Ed: Gordon Haff from IBM, a former 'analyst', on rebranding servers as "clown"]

    Hybrid cloud has come to mean different things over time. One early canonical document from the National Institute of Standards and Technology (NIST) focused on quickly and transparently moving workloads between a private cloud and a public one. This turned out to be both too narrow a definition and often not feasible because of the difficulty and cost of moving around large volumes of data. In fact, the recent interest in edge computing, in part, reflects the need to move computing closer to data and users. In this post, we’ll cover some key considerations to keep in mind as you start digitally transforming your organization.

  • How do you handle NIST's separation of duty requirements?

    Sysadmins, as you know, wear a lot of different hats--meaning that sysadmins do a lot of different jobs and typically have ultimate power in all of them. The all-powerful root user account and its highly-protected password are good examples of that ultimate power. For those of you who perform work that falls under certain regulations, like those of Department of Defense (DoD) project, you may have to comply with guidelines from the National Institute of Standards and Technology (NIST) 800-171, which includes the separation of duties (Control 3.1.4).

  • Madeline Peck: Summer Intern Restart Up

    Red Hat Internship Round 2 for Summer 2021 is officially under way! Last summer it was a new and fairly wild time especially with covid being fully remote and starting at Red Hat. But this first week actually included a four day weekend, as well as a lot of new hire intern orientation meetings. Some open source, kubernetes, and red hat products bootcamps also sprinkled in there.

    In between meetings and bootcamps I’ve been going over how much of the coloring book to get done so I can finish as much as possible by the end of June- and I’ve attached below one of the pages I completed this week.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read 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.
