This docker series is insanely good! Thanks❤

[ritikakumar]

Best docker series - everything explained in depth

[springmemory]

I really recommend reading 'Optimizing builds with cache management' in Docker Docs after watching this videos - while it does repeat some stuff I think it also helps concepts sink down

[kekko]

ATTENTION at the end it gives the port error because we have port 4000 just assigned to the previous images, solved by deleting the previous images with port 4000

Best Docker Series ..! can you please just put all the commands you have used throughout all videos to the description of this series ? That will really help.

[mahmoudsamy]

You really solved my problem in my existing project, Thanks for that

[shubhrajit]

Most of the tutorials I watched before were theoretical and boring... Until I found this gem!

[whatisintelligence]

Thank you for this series! Very easy to understand and to follow. You could have saled your knowledge and teaching talent but you teach us for free. Bless you Ninja

Best videos to learn Docker. I looked into several videos in youtube but this series is the best for me as a newbie

[hamidmirghafoori]

To be able to have two containers up and running without port error, just use different port number namely: docker run --name image2 -p 4001:4000 -d appchached2

[JeffBarron]

questions: a) how can you access files external to the image b) can you provide startup parameters for when the container loads? e.g start a container with a stock code attribute, to run a task and then shutdown when complete.. b) can you stop a container from within the container, ie when a task is finished

[jorgerauljimenez]

This tutorial was really useful. It is a great idea to run npm intall before copying the files.

[Star-hwbh]

Port already taken had shown up. But yeah thanks I understood. Thanks very much for every tutorials

[arkimphiri]

I will not stop lol, until I see a Ruby on Rails course. Please a Ruby on Rails Course

[tech-networking]

Excellent explanation, now I know they are in cache and can be retrieved when it comes to build new image

[odddellarobbia]

Really excited to learn docker, but maybe i'll wait till the series is complete.

[nurudeenkamilu]

Great explanation. However the package.json file content can also be changed at times

[GM-jezp]

consice and to the point, thank you!!

[macusgeorgiev]

Did we need to copy the package-lock file as well? It should force the specific dependency versions if it exists.

[shrikantsharma]

Small Mistake:
myapp5_c container run is failed.
Port 4000 already in use.
