Learn Docker - DevOps with Node.js & Express

Learn the core fundamentals of Docker by building a Node/Express app with a Mongo & Redis database.

We'll start off by keeping things simple with a single container, and gradually add more complexity to our app by integrating a Mongo container, and then finally adding in a redis database for authentication.

We'll learn how to do things manually with the cli, then move on to docker compose. We'll focus on the challenges of moving from a development environment to a production environment.

We'll deploy and Ubuntu VM as our production server, and utilize a container orchestrator like docker swarm to handle rolling updates.

This ain't any tutorial. This is a professional course. Thank you so much Sanjeev!

[manikandansivasankar]

This literally is a cheatsheet for anyone who aspires to be a DevOps engineer.
Excellent content. Thanks for all the hard work that has been put into making this wholesome course.

[FilipeFreire]

Explaining Docker with such ease sure doesn't seem like an easy task, but this guy sure nailed it! Fantastic job really, amazing to have this for free! Cheers!

[therealmattplayer]

Absolutely brilliant! Perfect pace, excellent explanations and his way of letting something fail to investigate why and how to remedy the issue. Most of the docker tutorials I have found seem to assume that you already know a lot about docker or its underlying concepts but this guy really does take you through in such a logical way. I'll definitely be checking out his other videos once I am through this!!

If you get "bash: mongo: command not found" at 1:49:00, then Use mongosh. mongo shell was deprecated in mongo:6.0.

[iadorepop]

I was searching for good docker tutorial to use in my project. Thanks free code camp. You guys never disappoint!

[kartikgarasia]

Hello Sanjeev I jave just completed this course and I have nothing but respect for you. Doing so much hard work and providing it for free is not an easy thing to do.

It really helped me understand how to deal with docker. Now I am comfortable adopting docker workflow in my projects. Once again thank you so much for creating this series.

[aroneinhorn]

Just now finished this over five hour course. It is very informative and easy to follow along. Thank you very much to Sanjeev. And thank you to Quincy for bringing this to us.

[tonimaunde]

I can thank you enough for this. From a complete newbie in DevOps, in 2 days I was able to dockerize and put into production my Express and Postgres api + Nginx. Thank you.

[Djzaamir]

One of the most comprehensive docker tutorials on the internet.

[yuqin]

One of the best docker and node tutorials I've taken.
The explanation is clear, the code is pretty, the author is funny.

[GauravYadav-rvwx]

Sanjeev Thiyagarajan, you have the ability to become a real teacher. You can solve the curiosity. Thanks. Keep up the great work

[chaoticqubit]

Sanjeev is an O.G. instructor! No doubt about it! I completed your FastAPI course, now the docker course. My respect for you has grown infinite times now.

[emirhansoylu]

The *BEST* tutorial about Docker I've seen on YouTube. I can't believe it's free. Thank you Sanjeev.

[wforbes]

This is like 20+ tutorials rolled into one cohesive project. Thanks and props to Sanjeev

[cagataysert]

I have just completed a Docker tutorial and I was looking for a hands on experience, so I am really happy to find your video. Thank you so much sir! Awesome job!

[chrispohlmann]

Just for information: The command mongo to log into the database is deprecated. As of now it is mongosh -u "username" -p "password"

[DaviAreias]

It took me a lot of time to begin to understand Docker and I’m glad I’ve found this video, it makes thing super fun if you already learned how to deploy an app to a server

[Shpatak]

Thank you for this descriptive course! That's what I've been looking for a while!
God bless you, mate!

[VipulGoel]

Best video ever I've watched, all real life development issues with clear explanation are mentioned and implemented with solutions...
