Docker enables you to create instances of an operating system running within a “container” which doesn’t access the host computer unless it is explicitly requested. This is done using a Dockerfile, which is a file that describes in detail all of the settings and parameters for said instance of the operating system. This might be packages to install ahead of time, or commands to create users, compile code, execute code, and more.

This instance of an operating system, usually a “server,” is great because you can throw the server away at any time and rebuild it with practically zero effort. It will be just like new. There are many reasons to want to do that; who doesn’t love a fresh install with the bare necessities?

On the surface (and the rabbit hole is deep!), Docker enables you to create an easily repeated formula for building a server so that you don’t get emotionally attached to a server.

    Crazy to see this in my feed, I was just thinking about this the other day. I didn’t steal the balls, but I remember figuring out that I could remove them and clean the crud off of the rolling components inside to smooth my cursor movement. (This would have been 3rd or 4th grade.)

    In my experience, Ubuntu and Ubuntu variants make for a great daily driver for someone who is new to Linux. When I started to get into Linux, I just found the most Q&A content and support for Ubuntu as I googled my way through it. This plentiful support was specifically geared towards newcomers, which I felt the other Linux communities lacked in comparison.
