DOCKER image vs container: Difference EASILY explained with for beginners. Rebuild on file changes

Bro, thank you very much, this is a really great vídeo and you have saved me!!!

nice

Nice, thank you!

I meaaaaaan, it's no different from compiling code. You can't run the old executable, or object files, and expect your new code changes to take affect. Is this really a difficult concept? Are compiled objects no longer taught in Comp. Sci or coding bootcamps? Anyway, I like the video it is a great explanation of an old concept.

What if my docker-compose file creates 3 containers as such:
1- web app (Django)
2- db (Postgres)
3- nginx

and i wanted to change some code in the Django files, without rebuilding everything and losing Postgres data?

Thankyou so much for the an amazing explanation !!

Many thanks for this!

Das beste Video das ich zu dem Thema finden konnte und extrem gut erklärt

Thanks so much for this video, I am new to using docker and I was very tired to have to delete and build the image manually every time I made a change into my code, now I have a better understanding of how docker works.

Nice video I like those graphical explanations
