As usual, when I need to really understand how something works, I come here. Thanks!! Some long form videos on Docker would be much appreciated.

This intro video was pure gold, out of all the docker beginner vids I watched, this is the first where I actually was able to follow along every step. Please do more vids going in-depth into docker, like docker-compose, and how to create a good dockerfile. I’ll definitely stay tuned for more vids. 🙏🙏

I sampled a number of videos before finding this one and this here hits the nail on the head. Knowing something is one aspect, but teaching it or impacting the knowledge is an entirely different aspect that not too many know how to do. But you sure have the gift of teaching. I did not hesitate to hit the like and subscribe buttons

This was truly fantastic to follow along! Any more videos coming from you about Docker will be much appreciated! ♥

Hi Amber. The Analogy of comparing houses with docker to explain the difference between image, container and dockerfile is just brilliant. god bless you.

쓸데없는것 없이 핵심만 있고 영상이 이해하기 쉬워서 좋았습니다. 감사합니다.

Thank you. But carrying the example of your nephew further, what still needs to be done so your nephew can run the image? For example, does he need tar? Does he need a docker run environment? How do you send the image to your nephew? Do you and he use docker hub for the transfer?

Concise and clear presentation. Thank you. Can you produce a similar presentation for Kubernetes, if only to highlight any differences.

Please do more tutorials on docker and microservices
