  • YAML for beginners | Enable Sysadmin

    YAML Ain't a Markup Language (YAML), and as configuration formats go, it's easy on the eyes. It has an intuitive visual structure, and its logic is pretty simple: indented bullet points inherit properties of parent bullet points.

    But this apparent simplicity can be deceptive.

    It's easy (and misleading) to think of YAML as just a list of related values, no more complex than a shopping list. There is a heading and some items beneath it. The items below the heading relate directly to it, right? Well, you can test this theory by writing a little bit of valid YAML.

  • colorls – turbocharged alternative to ls

    The part of the operating system responsible for managing files and directories is called the file system. It organizes our data into files, which hold information, and directories (also called ‘folders’), which hold files or other directories. Several commands are frequently used to create, inspect, rename, and delete files and directories.

    One of these commands is ls, which prints the names of the files and directories in the current directory. A directory is really just a file. It’s a special file with special rules. The ls utility appeared in the first version of AT&T UNIX.

    Are you looking to liven up your shell? Want a bit more beauty on your terminal? colorls might be the ticket. colorls is a command-line utility that aims to improve on ls. color is written in Ruby.

  • 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.
