  • How to Install Gradle Build Tool on Debian 11

    Gradle is a build automation tool that is based on a concept called ‘incremental builds’. It speeds up the development process by, for example, building only those parts of the project that have been modified. Incremental build works by (conceptually) tracking which files were changed and then using this information to determine what needs to be built. This helps Gradle avoid executing tasks that are not necessary.

    Gradle can be seen as an analog of Apache Ant or Make, but it also has features typically associated with continuous integration tools like Jenkins: tasks can be executed in parallel, and tasks can depend on other tasks (this makes it possible to specify task execution order).

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.
