Thank you. At last! I've dipped into dozens of docker videos over the past few months and, apart from getting a vague idea of what docker is, had no clue about the basics of building a docker image. This video is gold dust.

Dude, that was amazing! I'm a career software guy and career technical trainer. Your content and approach were great. I was having trouble finding the "simplest, easiest example" of deploying something to Docker. In your intro you said that this is it. You were right. Now, all of the crap I've read and tried but failed, suddenly all makes sense. Dirt simple. No shenanigans. Excellent work! I should be deploying micro-services written in Java to Docker in no time.

This is awesome. I had started going down the path of learning docker from the docker website and that felt more like a recipe without context. This short video helped me understand more about docker than the couple of hours I had already invested prior to this. Awesome video! Thanks!

Hey Derick, thank you very much indeed for putting together such an easy to follow tutorial. I had been confused up until now about how the Docker image composition process works. Thanks again.
