  • Red Hat Ceph Storage RGW deployment strategies and sizing guidance

    Starting in Red Hat Ceph Storage 3.0, Red Hat added support for Containerized Storage Daemons (CSD) which allows the software-defined storage components (Ceph MON, OSD, MGR, RGW, etc) to run within containers. CSD avoids the need to have dedicated nodes for storage services thus reducing both CAPEX and OPEX by co-located storage containerized daemons.

    Ceph-Ansible provides the required mechanism to put resource fencing to each storage container which is useful for running multiple storage daemon containers on one physical node. In this blog post, we will cover strategies to deploy RGW containers and their resource sizing guidance. Before we dive into the performance, let's understand what are the different ways to deploy RGW.

  • OpenShift 4.2: New YAML Editor

    Through our built-in YAML editor, users can create and edit resources right in the Red Hat OpenShift Web Console UI. In the latest release, we’ve upgraded our editor to include language server support.

    What is language server support?

    The language server support feature uses the OpenAPI schema from Kubernetes to provide content assist inside the YAML editor based on the type of resource you are editing. More specifically, the language server support offers the following capabilities:

    Improved YAML validation: The new editor provides feedback in context, directing you to the exact line and position that requires attention.
    Document outlining: Document outlines offer a quick way to navigate your code.
    Auto completion: While in the editor, language server support will provide you with valid configuration information as you type, allowing you to edit faster.
    Hover support: Hovering over a property will show a description of the associated schema.
    Advanced formatting: Format your YAML.

    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.
