  • How To Install Eclipse IDE on Debian 11 - idroot

    In this tutorial, we will show you how to install Eclipse IDE on Debian 11.

  • How to stop Firefox from auto updating in Linux

    In Linux, Firefox has this bad habit of wanting to update itself when you’re not ready to perform that task. And it will not let you open a new tab or window until you allow it to apply the update. I find it very annoying. There are any number of knobs you can tune to disable this feature in about:config, but there’s no guarantee that they’ll work as expected. And if you use more than one Firefox profile, as most power users do, you’ll have to tune about:config for each profile. In this post, I’ll show you how to do it system-wide, and it’s guaranteed to work.

    With the default setting, Firefox will download and install the update in the background, and then throw up the prompt shown here when you want to open a new tab or window. That means you won’t be able to open that new tab or window until you agree to restart Firefox. And that almost always happens when I’m in the middle of doing something very important and not ready to restart Firefox.

  • How to Index Your Docker Image’s Dependencies With Syft – CloudSavvy IT

    Syft is a CLI utility that generates a Software Bill of Materials (SBOM) for container images. An SBOM is a catalogue of dependencies used by your image. It gives you visibility into the “materials” that form your image’s filesystem.

    Producing an SBOM can help you identify overly complex package supply chains that put you at risk of dependency confusion attacks. Distributing an SBOM alongside your image informs users of what lies below the surface. This provides a useful starting point when tightening supply chain security.

    Syft is developed by Anchore which also offers a complete container scanning engine. The Syft CLI is capable of extracting package lists from images using popular operating systems and programming languages. Both Docker and OCI images are supported.

  • How to Mount or Symlink a Single File in a Docker Container – CloudSavvy IT

    Docker volume and bind mounts are used to bind directories on the host OS to locations in the container’s file system. While they’re commonly used to mount entire directories, you can also use them to symlink individual files.

  • How (and Why) to Run Docker Inside Docker – CloudSavvy IT

    Running Docker inside Docker lets you build images and start containers within an already containerized environment. There are two possible approaches to achieve this depending on whether you want to start child or sibling containers.

    Access to Docker from inside a Docker container is most often desirable in the context of CI and CD systems. It’s common to host the agents that run your pipeline inside a Docker container. You’ll end up using a Docker-in-Docker strategy if one of your pipeline stages then builds an image or interacts with containers.

  • 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.
