Docker + Node.js/express tutorial: Building dev/prod workflow with docker and Node.js

Docker Docker Docker Docker and even more Docker. This is the first of many docker videos I hope to pump out. In this video, i'm going to walk you through how to setup a development workflow for node.js/express apps with docker. I tried searching online for a good video, but there wasn't one that took everything step by step, so I decided to make one.
We'll be covering a lot of good stuff like, building images using dockerfiles, learning about volumes and bind mounts, setting environment variables, automating with docker-compose, and splitting up our development and production environments

This is one of those videos you skip when you're a beginner, because it seems so daunting, but in the end it's that video that makes all the other random bits of info you found click into place, finally making it all understandable.

[@sandeepkosta5750]

You said what i just felt. 🤣🤣

[@syncpoint]

I am not going to skip 😉

[@bilza2023]

thanks for the heads-up

[@jallpass]

yeah this is honestly the best video I could find on youtube

[@joekane9235]

Absolutely superb, much better than some other paid resources I used. This is perfect for beginners who have a concept of what an image or container is and are looking to dockerise some projects or create from scratch. The best explanation of Dockerfile and compose that I have seen, with all the supplemental information you need to develop you understanding as opposed to regurgitating steps in a process.

[@edwardoakley8659]

This is, and I can't express highly enough, exactly what I was looking for! Perfect tutorial, clean, clear, all the information you need. Thanks dude

[@spaceghost166]

Thanks for the video! Super clear and well explained!

[@RajeshRRajamani]

[@cemyurtbas7668]

Thank you so much, time well spent on watching and learning :) Big thanks for explaining all micro knowledge you have for new starters like me. Sending big hugs from Turkey.

[@santhoshmj7116]

in environment variables section why you enter the port 4000 while run the container but in Dockerfile you mention 3000?

[@sematoghem]

it's answer beginners what thing doing. great....

[@josebarraza118]

please create a tutorial for dockerizing mongodb with this express app

[@elektrixmk]

Thanks for the great video! Curious - would it be possible to sidestep running the bash command (for the multi-environment support) in the Dockerfile and use Docker's multi-stage builds instead?

[@SanjeevThiyagarajan]

You 100% can do it with multi-stage builds. Multiple ways to accomplish things

[@elektrixmk]

@@SanjeevThiyagarajan yeah, no question about that! I was just wondering if you maybe have any examples / patterns of such an approach? Thanks!

[@igadget777]

Thanks for the video. I like the way you explain things. Only issue I'm having is that for some reason my .dockerignore file is not working and all the files are copied. Any ideas? Thanks.

[@SanjeevThiyagarajan]

Docker ignore is just for building images. If u have a bind mount then it will sync all files

[@jasonl9630]

Help me use this for typescript, my types is not being registered because node_modules is empty on the host

[@jimshtepa5423]

at 52:16 when you print the list of file in the running container you can see the Dockerfile exists inside the container although we have explicitly included it in the dockerignore file.Could you please explain why that is happening?

[@lalitsekharbehera6012]

i think it's because of the volume!

[@davychhouk]

Thank you for a great tutorial. This has been very helpful to me. It would be great if you could put this code on a github repo. It would help a lot.

[@SanjeevThiyagarajan]

Here you go man. Keep in midn i made a follow up video to this course that includes all the content from this video plus another 3hrs of content so the github repo has the final config for that video. github.com/Sanjeev-Thiyagarajan/node-docker
