Docker is an amazing piece of technology. And I'm sad to say, I took it for granted for many years. This is the video I wish I had when I started learning Docker. We'll be talking about virtualization, containerization, and the difference between the two (because this stuff was messed up in my head for a long time). Before you know it, we'll cover Dockerfiles, images, and building containers.

So join me in a gentle introduction to docker. Let's get into it.
