This is the most clear explanation I ever seen at YouTube for Docker.
All other videos I watched before in other channels they just explain like they are robots.

I love your Docker series. Your teaching style is clear, straight to the point, and very methodical.
Thanks for the time and efforts you've put into this. Really appreciate it!

The greatest explanation about Dockerfile. I was typing things in this file just for the sake of typing because i saw it working in a tutorial, but from now on, i know what each and every single layer mean. Thanks Shaun!

finally someone that takes the time to actually explain the syntax while they go structure of the language is critical in order to learn, yet so few actually tell you what you are doing, they just tell you enter this blah de blah enter that yada yada. Thanks man i was going crazy trying to find something that gave me a clue lol

You have your dependencies installed after the source code in your example docker file. Docker caches layers, and by installing dependencies before copying the source code, you can leverage this cache mechanism. If the dependencies don't change often, Docker can reuse the cached layer with the installed dependencies, which speeds up the build process. By installing dependencies after copying the source code, the cache will be invalidated whenever your source code changes, even if the dependencies remain the same. This leads to longer build times.

I'm so grateful for people like you in the YouTube! I just needed to review the Docker's main concepts and this series is helping a lot! Thank you!

I've watched multiple tutorial about Docker only you could explain this clearly. keep going (y)

[donalslemon]

This was exactly what I needed, thank you and well done. Clearly explained, with specific elucidation of the command usage and meanings. I'll be checking out the rest of the videos in this series as I still have questions around the 'AS base' and 'AS build' modifiers as well as how 'ENTRYPOINT' works.
