Perhaps it's unsurprising that this includes virtual servers and workstations, but many sysadmins don't realize they can manage virtual machine creation from Cockpit.

    Suppose you've been using virt-manager, GNOME Boxes, or some other tool to spin up virtual machines, but you use Cockpit for diagnostics and maintenance. In that case, you can now consolidate your tasks by managing virtual machines in the same interface.

  • 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.
