    When this happens, you can either go without your virtual machines and wait for the VMware team to update the kernel modules—which could take a few days or longer—or you can fix the kernel modules yourself.

  8. How to migrate from CentOS 8 to CentOS stream conversion

    As you know, CentOS 8 is ending soon. Red Hat is making the shift from CentOS 8 to CentOS Stream. CentOS stream places itself between Fedora Linux and RHEL. It is not 100% RHEL clone but ahead of RHEL development. Think of it as a midstream distro. Of course, if you need 100% RHEL compatibility, then you need Rocky Linux or AlmaLinux. However, the CentOS stream is more than sufficient for me as I only need Apache, Perl, and Python for my use case. This page explains how to migrate the existing installation of CentOS 8 stable to CentOS Stream without reinstalling a new operating system.

    CentOS Stream is an open-source operating system and one of the replacement candidates for CentOS 8. However, I decided to stick with CentOS Stream because I didn’t have time or energy to install a new replacement such as Rocky Linux or AlmaLinux. Then restore data. It is too much work for my side project. Eventually, I will convert my legacy app to Docker format, but for now, I am going to upgrade my VM and save some time. So without further ado, let us see how to migrate from CentOS 8 to CentOS Stream using the ssh command.

  • 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.
