First time in my life watching something related to Docker. Understood everything. Put it into practice on my own project. Absolutely outstanding tutorial. Best there is by light years!

[ThatFirstRep]

I am speecheless...I knew nothing about Docker an hour ago and here am I already creating my own images and running them inside containers. What a Thanks a ton Nana. I had to hit that Subscribe button! 🙏🔥

I'm a long time follower of your channel, and love the way you teach. There are a lot of very talented instructors here on YouTube, and I appreciate every one of them. What sets you apart from the rest is that you explain even the little details that everyone else glosses over, for example, " -it means interactive terminal " . That one little detail made learning k8s so much easier! Please keep up the great work!

I have watched around 5-7 "beginner" tutorials on Docker, but none came even close to the comprehensiveness of this tutorial. This tutorial clarifies thoroughly the fundamentals of Docker at a perfect pace! Forever in your debt! :D

This is the best crash course I have seen on Docker. In 1 hour I was able to fully understand the basics that I have struggled with for a while. Thanks Nana!

[informatik]

An outstanding tutorial. All the main important moments are clearly explained and shown in practice in just an hour - a really great work!
10/10 👍
Definitely the best Docker introduction I've seen so far.

A great introductory course. Simple and concise.
Slight correction for the Dockerfile section of the video.
- *The commands in a dockerfile are not RUN/MAPPED in the container, only while BUILDING the image.*
- _If it were, spinning up new containers would take longer as dependencies would have to be installed for each new container._
- Building a Docker image creates an object (the final layer) which specifies folder structures and contains all the necessary files i.e. base image files, installed package files, your program code and all other artifacts created as a result of the instructions in your Dockerfile.
- Running the image creates a process (the container) to manage an ISOLATED instance with a folder structure and content continuing from where the image ended i.e. "run your code".

This is why 2 containers based on the exact same image may have different contents at run time depending on what your code is doing to the file system: docker exec [ContainerId] ls .
These underpin why a basic knowlege of Linux (file system and commands) is usually advised before learning Docker.

The best Docker Crash course I have seen till date, thoroughly enjoyed it. I have more than a decade experience in IT and I can safely say your way of teaching inspires me. Keep it up Nana, keep uploading more tech videos like this !! :)

[DeliberateGeek]

I'd never run into your channel before. I've been in tech my entire career, and while I've bene familiar with Docker in the abstract, I simply haven't had a pressing need until now. I'd played with it years back, but then hadn't touched it. This video was the perfect recap to both remind me of what I'd learned before and to fill in a couple of gaps that I hadn't even known I had. Thanks very much!

[sharkofjoy]

This is so much better than any of the other Docker videos I tried. This is the minimum amount of info needed, love it! Any tutorial with less information is leaving out something essential.

[TlatoaniItzcoatl]

This was such a great course. It gave me everything I needed to no feel overwhelmed when getting started using docker. Thank you so much for making this free, it looked like it took a lot of effort to put it together as it is present so well.

[TheAmateurLifestyle]

Hi! I have been working towards my A+, and plan to go for CCNA after that. In the mean time as part of a homelab I wanted to create some minecraft servers using docker. I was quite overwhelmed, but your video is amazing! You explain each part and not just "show me how". I look forward to watching other videos of yours. Just want to say TYSM!!

[machinimaaquinix]

Honestly this is the best and most up to date Docker crash course. It def gave me everything I needed for an upcoming project. It de-mystified all the jargon and everything is explained step by step in a good progression. I'll be checking out your online courses! Thank you so much for providing this!

[Armchair_Warrior]

Nana your courses are so awesome. I really appreciate your pacing and in-depth explanation. I've not had the opportunity to work much with containers professionally, and your tutorials are really helping me out as I implement them first in my home lab, and later at my job. Your hard work is appreciated!

Been in industry for 2 decades. These 1 and 4 hours courses are a boon for a large segment of population. Thanks a lot !

[JenOfFlowersong]

I have been out of the development world for about a decade. This video was SUPER helpful in updating my brain to the current day about application virtualization. THANK YOU so much for creating this excellent presentation.

[hugoruivo]

this course is gold! been postponing learning how to use docker and you made it simple to learn and how it works behind the scenes. Thanks for doing this!

[karimimajed]

Wow, I can't believe it! I learned Docker in one hour. You are amazing!

[abhisheksaxena]

This is one of the best docker beginner tutorial. Amazing easy to understand tutorial with simple explanations with animations and live demo. Thanks Nana

[Dubergomezfonseca]

I have never done or used docker in the past, but, I have been wanting to learn. Now I am motivated to go deeper into this subject. Great Job!!!!
