Docker images and containers are the two words everyone mixes up. In this video I explain the difference in the simplest way possible - using a recipe and a plate of food and then we do it for real on the machine.
By the end of this video you will have run a real web server, run two copies of it at the same time, gone inside a running container, changed a live website, and seen exactly why that change disappears.
No prior experience needed. If you have Docker installed, you can follow along.
