  • Deep dive into Ansible ad hoc commands | Enable Sysadmin

    Automation plays a vital role in a sysadmin's or DevOps administrator's day-to-day life; patching, installing, managing components, automating network devices, and dealing with containers are tasks that automation can handle. Due to the sequential behavior of scripting, many sysadmins have not considered automation to be a promising tool. Ansible, as an automation tool that executes in parallel, appears to be changing that trend and becoming widely used.

    Ansible uses ad hoc commands and playbooks to achieve automation. Ad hoc commands are mostly single linear commands that can execute from controllers. Ad hoc commands make Ansible useful even when a sysadmin needs to perform a one-time activity.

  • Test container images in Red Hat OpenShift 4 with Ansible and CI/CD | Red Hat Developer

    Several repositories offer ready-made container images for Red Hat Enterprise Linux and other systems running Linux. The InterOp team at Red Hat tests these application images in Red Hat OpenShift. To simplify the integration of tests into the continuous integration/continuous delivery (CI/CD) process, we are adding Ansible playbooks to the repositories that host the container images. The Red Hat Software Collections GitHub repository currently has the first of these Ansible playbooks, but we will add playbooks to other repositories over time.

    This article shows how to submit a test to a repository, and how to download the tests if you want to run them in your own container environment.

  • Use dnf updateinfo to read update changelogs - Fedora Magazine

    If you have used any type of computer recently (be it a desktop, laptop or even a smartphone), you most likely have had to deal with software updates. You might have an opinion about them. They might be a “necessary evil”, something that always breaks your setup and makes you waste hours fixing the new problems that appeared, or you might even like them.

    No matter your opinion, there are reasons to update your software: mainly bug fixes, especially security-related bug fixes. After all, you most likely don’t want someone getting your private data by exploiting a bug that happens because of a interaction between the code of your web browser and the code that renders text on your screen.

    If you manage your software updates in a manual or semi-manual fashion (in comparison to letting the operating system auto-update your software), one feature you should be aware of is “changelogs”.

    A changelog is, as the name hints, a big list of changes between two releases of the same software. The changelog content can vary a lot. It may depend on the team, the type of software, its importance, and the number of changes. It can range from a very simple “several small bugs were fixed in this release”-type message, to a list of links to the bugs fixed on a issue tracker with a small description, to a big and detailed list of changes or elaborate blog posts.

    Now, how do you check the changelogs for the updates?

    If you use Fedora Workstation the easy way to see the changelog with a GUI is with Gnome Software. Select the name of the package or name of the software on the updates page and the changelog is displayed. You could also try your favorite GUI package manager, which will most likely show it to you as well. But how does one do the same thing via CLI?

  • Junichi Uekawa: openvpn client configuration with systemd.

    openvpn client configuration with systemd. Spent a while trying to figure out why my configuration file /etc/openvpn does not take effect. It was because I needed to tell systemd to reload the daemon stuff and trying to restart openvpn only did not have any meaningful effect. After I learnt how things work it made some sense, but I expected /etc/init.d/openvpn restart to do the right thing.

  • 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.
