  • The GNOME Infrastructure is moving to Openshift

    The cluster consists of 3 master nodes (controllers, api, etcd), 4 compute nodes and 2 infrastructure nodes (internal docker registry, cluster console, haproxy-based routers, SSL edge termination). For the persistent storage we’re currently making good use of the Red Hat Gluster Storage (RHGS) product that Red Hat is kindly sponsoring together with the Openshift subscriptions. For any app that might require a database we have an external (as not managed as part of Openshift) fully redundant, synchronous, multi-master MariaDB cluster based on Galera (2 data nodes, 1 arbiter).

    The release we’re currently running is the recently released 3.11, which comes with the so-called “Cluster Console”, a web UI that allows you to manage a wide set of the underlying objects that previously were only available to the oc cli client and with a set of Monitoring and Metrics toolings (Prometheus, Grafana) that can be accessed as part of the Cluster Console (Grafana dashboards that show how the cluster is behaving) or externally via their own route.

  • Modernize your application deployment with Lift and Shift

    For many software modernization projects, it’s all about learning to love, lift, and shift. No, wait. It’s all about learning to love lift and shift. The basic idea behind lift and shift is to modernize how an existing application is packaged and deployed. Because it’s not about rewriting the application itself, lift and shift is typically quick to implement.

    Modern development environments rely on containers for packaging and deployment. A modern environment also uses a continuous integration / continuous deployment (CI/CD) system that automatically builds, tests, and deploys an application whenever its source code changes.

  • Istio on OpenShift: Technology Preview 2 of Service Mesh Now Available

    It’s been a few weeks since the release of the first tech preview of Istio on OpenShift. Since then a lot has happened, and we are happy to announce the availability of our second tech preview release.

    In this release we are adding a whole new user interface from the upstream Kiali project. The Kiali user interface can help Istio users understand what’s happening in their service mesh, canl show how the various components are connected, and can help to detect issues (HTTP 500, pod not started, misconfigurations) to better fix those.

  • 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.
