  • How to add an OpenPGP repository key, now that apt-key is deprecated

    Now, you'll see the following warning: "Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead." What do you do?

    To install certain applications from non-standard repositories, those keys must be added. How do you add them? Unfortunately, it's not quite as easy as it once was. You'll still be issuing a command that pipes the downloaded file into another command, with the help of sudo.

    The confusing part is that you'll no longer use apt, in any way, to add the key. You'll be adding the key to your keyring. Let's stick with our Opera example, although installing Opera via their .deb package automatically installs and configures their repository for you.

  • How to install Foreman on Rocky or Almalinux 8 - Linux Shout

    Foreman is an open-source lifecycle management suite – this means that it covers all tasks that are pending, from creation to configuration and monitoring of a system. It is doesn’t matter whether it is physical or virtual systems or Docker containers, Foreman works the same for all of them. Hence, with the help of this provisioning, configuration, orchestration, and monitoring platform physical systems can therefore simply boot from the network and be installed automatically and standardized. Numerous hypervisor and cloud platforms can be addressed through plugins, for example, VMware, oVirt, Amazon EC2, Microsoft Azure, XEN, OpenStack, OpenNebula…

    Puppet is used by default for configuration management – however, Chef, Salt, or Ansible can also be used via plugins. Corresponding configuration rules can be created via the Foreman web frontend and the consistency of the system landscape can be displayed.

    You can use the command line or a Cockpit plugin, and it’s a fairly simple and straightforward process which allows you to create images for most of the major platforms – Libvirt/KVM (RHV or general Linux virtualisation), VMware, Openstack, AWS and Azure. You can also deploy these images from Satellite.

  • Creating images for Toolbox

    One of the first things I needed to do in Toolbox was to create a custom image based on Red Hat Universal Base Image (UBI) that resembles the UX the users get with fedora-toolbox image, so I needed to learn how to create custom images for toolbox. It is surprisingly easy to do that!

    The first thing I needed to do was to take a look to the Toolbox documentation. In the toolbox repository file there is an explaination of what do you need to create your custom images.

  • Step by step guide to create Docker Image - LinuxTechLab

    We have, in our earlier tutorial discussed the Dockerfile i.e. what are Dockerfiles & how to create one. We also mentioned three different examples, one each for CentOS, Fedora & Ubuntu to create docker images with Webserver (apache).

    We will now use one of those Dockerfiles (CentOS one) to create a Docker image & will then upload the created image to Docker Hub. To simply explain Docker Hub, it's a public registry that has over 15000 images that can be directly used or can be used to create a custom Docker image. Docker Hub is directly maintained by Docker.

  • 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.

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.
