  • Fedora & root account is locked boot issue - Solution

    Three years ago, I wrote an article that explaining how to recover from a failed boot following a major version upgrade in Fedora. At that time, I was working with Fedora 25, and suddenly, I was no longer able to get to the desktop. The issue turned out to be a buggy initramfs, which is an issue I've only encountered once in the past, back in Ubuntu, back in 2009. Since, it's been quiet.

    Well, the wheel of time has dumped us back at the beginning. The same issue happened again. I had (somewhat) recently upgraded an instance of Fedora 29 to Fedora 30, and lo and behold, I found myself facing the same problem. Almost. I had a black screen, and a message that said: Cannot open access to console, the root account is locked. At this point, trying to do anything didn't yield any results. I could only reboot. I did try another kernel, and this helped - I got to my desktop. While the issue seems to be similar, I had to go a slightly different way about fixing it.

  • Satellite and Ansible Tower integration part 1: Inventory integration

    Do you use Red Hat Satellite and Red Hat Ansible Automation Platform? As far back as Satellite version 6.3, these products can be integrated together. Once integrated, Ansible Tower will be able to pull a dynamic inventory of hosts from Satellite. In addition, once a Red Hat Enterprise Linux (RHEL) host is provisioned by Satellite, it can be configured to automatically make a callback to Ansible Tower to run a playbook to configure the new host.

    This post, which is part one of a two-part series, will show how to set up a dynamic inventory in Ansible Tower that pulls a list of hosts from Satellite, and cover examples of how to use this dynamic inventory. The second post in the series will cover how to automatically make a callback to Ansible Tower after newly provisioned hosts are built from Satellite.

  • OpenShift 4.3: Deploying Applications in the OpenShift 4.3 Developer Perspective

    In this article, we will take a look at improvements in the user flows to deploy applications in OpenShift 4.3 Developer Perspective. You can learn more about all the improvements in the OpenShift 4.3 release here. Since the initial launch of the Developer Perspective in the 4.2 release of OpenShift, we’ve had frequent feedback sessions with developers, developer advocates, stakeholders, and other community members to better understand how the experience meets their needs. While, overall, the user interface has been well received, we continue to gather and use the feedback to enhance the flows.

    The +Add item in the left navigation of the Developer Perspective is the entry point for the developers to add an application or service to their OpenShift project. The Add page offers six user flows for adding components from Git, deploying Container Images, adding an item from the Developer Catalog, importing your Dockerfile from a git repo, Importing YAML or adding a Database. Developers can easily create, build and deploy applications in real-time using these user flows.

  • OpenShift 4.3: Creating virtual machines on Kubernetes with OpenShift’s CNV

    Whether you are a new or a seasoned Kubernetes user, or you’re just considering working with Kubernetes, you have probably started exploring the technology and how best to integrate virtual machines with the Kubernetes engine. But which solution fits your needs? Is there a way to leverage both the isolation virtual machines provide and the orchestration platform of the Kubernetes engine? With Red Hat OpenShift, you can do both.

    OpenShift 4.3 offers the ability to run both container-based workloads and virtual machines side by side as workloads on a Kubernetes cluster. Installing the Container-native virtualization operator on OpenShift will allow you to create, run, and manage VMs, as well as provide templates to quickly create the same VM multiple times.

  • 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.
