IBM/Red Hat/Fedora Leftovers

  • Single Node OKD (OpenShift)

    Everytime I get to use Red Hat’s Open Shift I think to myself: “I should use OpenShift more”. It is a really great tool not just for high availability clusters but for general software development also. Its Web interface is super intuitive and nice to use, and you can provision all sorts of stuff in minutes. And everything is open source. Its really great.

    So naturally I decided to run it locally, especially after the news that starting from version 4.8 you can use it on single node architecture also. I decided to run it virtualized in libvirt so I can destroy it if I no longer needed. Hooray!

  • Fedora on NVIDIA Jetson Xavier – nullr0ute's blog

    The last two years or so I’ve been working with NVIDIA on general distro support including UEFI and ACPI for their Jetson Xavier platforms. Their Xavier platform, except a few quirks, are mostly SystemReady-ES compliant, so having a SBBR compliant firmware goes quite some way to having a widely available, relatively affordable, platform that “just works” for the arm ecosystem. I was very excited to finally have NVIDIA finally release the first version in March this year. This firmware is a standard UEFI firmware based on the open source TianoCore/EDK2 reference firmware, it allows booting in either ACPI or Device-Tree mode and supports all the basic things needed. The ACPI mode is not as fully featured as the Device-Tree mode as yet. In ACPI you get compute (cpu/memory/virt etc), PCIe, USB, network, which is just fine if you’re just looking for standard server or for testing a SystemReady system but there’s no display or accelerator support as yet. The Device-Tree mode is more feature full but both work pretty well with upstream kernels and NVIDIA are improving and upstreaming more things regularly.

    For flashing with the latest Fedora releases you’ll want the Linux for Tegra (L4T) R32.6.1 release and the latest UEFI firmware (1.1.2 ATM). The R32.6.1 release fixes issues with python3.9 and later so you’ll need that for Fedora. The following will extract everything into a directory called Linux_for_Tegra. Note the release for Xavier is different to the L4T for the TX1/TX2 series of devices such as the nano.

  • 20 years of Red Hat Product Security: The rise of branded exploits (Part 2)

    In part 1 of this story we traced the history of Red Hat Product Security from its inception in 2001 through to its shift into the Customer Experience and Engagement (CEE) team in 2013.

    But that was just the beginning...security was always important, of course, but it was about to become front-page news.

  • CentOS Community Newsletter: December 2021

    As we approach the end of 2021, I wanted to thank all of you who have worked so hard this year towards the betterment of the project. This year we've made governance more transparent, welcomed several new SIGs, made big strides in consolidating infrastructure with Fedora where it made sense, and begun to return to in-person events. We could not have done this without the passion and hard work of the project community. Thank you.

  • 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.
