Basically on Friday if someone has zero knowledge in docker they can walk into office on Monday as a master of docker..Amazing work Nana!!

This is one of the best tutorials I have run across in my 20+ years of software development. Excellent work. Quite remarkable.

VERY IMPORTANT FOR NEW WATCHERS: doing this with the latest version of mongo/mongo-express will result in an error during first setup. I found a fix for it though. The video is 4 years old, so I went and got 4 year old versions of mongo/mongo-express off of dockerhub, and it works just like the video intends. commands: docker pull mongo-express:0.49 docker pull mongo:4.2.1 hopefully you find this if you're stuck.

First 20 mins into the video, paused it, felt an urge to thank the author for such clear and in depth explanation.. Thank you so much Nana!

Thank you nana. I have been watching your videos and studied them for last 3 months. Finally, I got my first job as a DevOps engineer in a MNC. I just wanted to express my deep gratitude for the dedicated work you do day after day.

I am a teacher at university since 20 years already, I know how difficult it is to transmit knowledge and you do it in an extraordinary way. I need to learn Docker for my work and this has been a treasure. Thank you a lot! Greetings from Buenos Aires.

Halfway through this and all I can say is I have massive respect for you and the things you do for the tech world. This is the first docker tutorial I watched that made it looks so easy. Thank you, thank you thank you. You are the best!!!

Actually iam from non it branch.Now i can do without any help.. What a clean and clear explaination.. Thanks a lot mam

The fact we’re getting this content for FREE is amazing. Thank you for the amazing tutorials 🙌

Most perfect tutorial ever. Very detailed. Finally I learned Docker.

I am a student at NIT Srinagar. You just note down that from now on if any junior is going to come to me for docker tutorial I am recommending this youtube video to all of them. Stunning tutorial mam. I am beyond amazed.

Some people are just born to be teacher/coach, excellent work, many thanks

It's ridiculous how much valuable and clearly presented information is in this single video. Thank you very very much good lady.

Great tutorial. Wonderful progression of topics alongside practical demos. I knew nothing about docker before watching this tutorial and now I'm confident enough to integrate it to my projects. Thank you nana for this awesome tutorial

My understanding of docker and docker compose had been hazy for so long! After watching this course it’s now crystal clear on how it all works! Great job!

Thankgod I found this video at the early stage of Devops Preparation.. Thankyou soo much Nana.. Simply Brilliant

This is an EXCELLENT tutorial of docker. To the point, comprehensive and accurate!

The amount of effort gone into this tutorial is immense. Really good job Nana. I just learned docker for fun haha

Learned so much in such a short amount of time. Docker's been this scary, mysterious thing for a while for me, and this video did an amazing job of demystifying it. This video is an absolute gem.

Thanks Nana. Incredibly I learned more from your video in English than videos in Portuguese from my Brazilian compatriots who don't know how to explain Docker.🤗

Probably one of the best teachers in the world. Literally.

Very detailed and well-paced tutorial, thank you! Before this tutorial, I could run docker commands but never understood the details. Now, I have a good understanding and a mental model of containers and how to make containers from web applications and services. I'm now confident to apply it in my projects and start learning Kubernetes. Thank you, Nana!

This is the best Docker tutorial I've ever seen!! I want to like this video more than once but RU-vid doesn't allow me to do that. Thank you Nana!

This is the best docker tutorial I have seen so far. Explanation about docker volumes was top-notch, I couldn't understand the idea of volumes before . Thank you Nana!

This video is almost 2 years old but it still taught me so much and almost everything in this video is still relevant, Thank You for this 💖💖💖

You are doing a great job !! For people like us who are new to Devops its like meeting a messiah...God Bless you!

I have zero knowledge on Docker before watching this video but after watching it I feel like I know much about Docker and I can face any questions in interview. Thank you so much Nana for such a clear explanation. You are God sent angel to teach.

I’m glad I found you ! I am an experienced full stack developer but devops has become a mandatory requirement for most projects. I have prior cloud experience so it’s been easy for me to understand most things about containers, docker and kube concepts. Keep up the good work and continue what you are doing. A big thanks

This video is thorough, intense and well thought out and put together. Nothing but appreciation for you. THANK YOU!!!!!

Best docker tutorial on the internet. Period.

Amazing ..didn't have to rewind the video or google search terms used in this video, while watching. This course kept me attentive throughout the learning experience. We need more teachers like Nana in IT world. Thank you for being so awesome PS. beware such content can excite you to switch to devOps from regular dev roles

A clear and well structured presentation that takes a beginner from total ignorance to a level of practical competence. Thank you Nana. Much appreciated. I now feel like I understand how Docker containers work

This was an excellent tutorial. Extremely detailed and simple to follow along. This lesson was extremely valuable and will be used on my upcoming project. Thank you so much Nana!

This is one of the best tutorials I have seen for docker till now on youtube.

Hands down one of the best tutorials for docker. Very detailed and the example was so practical and simple. Keep up the good work Nana.

Honestly, this is very empathetic teaching. It's as if you know exactly what areas need more explanation and you give great examples and do a lot of repetition. Hats off, this was very useful!

By far the best course on Docker out there. Especially the Demo part is incredibly educational :) Keep up the good work.

I have been trying to learn docker from a long time and have seen various videos. But I can confidently say that this is the best tutorial on Docker that I have seen so far. For the first time, I am feeling confident about my docker knowledge. The explanation was up to the mark with all the required details for a newbie like me on docker. Can't thank you enough Nana for all the hard work and time that you have spent on this video.

Nana, this "Docker Tutorial for Beginners" video is an absolute gem! You explained complex concepts in such a clear, concise, and engaging way that even a complete Docker newbie like me could easily grasp them. Your enthusiasm and passion for the subject really shine through, making the learning process incredibly enjoyable🎓🎓

One of the best training video, I have ever encountered. Entire session was very smooth, to-the-point and excellently explained. The best thing is there there is no typos, errors, or dos here and there, everything explained very clearly. This indicates that you have a very deep understanding of the subject, and your knowlege is not just copy paste from the net. Excellent JOB...>>> Your efforts are highly appriciated. Thnak You..!

This is the best Docker tutorial for Beginners I have ever seen. Smooth, slow-paced, and going through all the details without overwhelming. This is a real gem. Thanks Nana!

the clarity of the examples is incredible , along with the designs to see in a graphical way what you are explaining , all together makes a great course, thank you very much for your effort!

Nana, i cant really thank you enough for this great course that you have created, There are very few people who actually believe in sharing knowledge, and YOU are one of them. Excellent work in putting this course together. You have helped me learn a new technology today and it was with so much ease that I couldnt hold myself to switch off my Laptop until this course completed.... Brilliant Work!! Love and Respect to you!!!

Really, This is the first ever video I've ever watched from the beginning till end.. Thank you so much Nana..

Best part is you are covering Why and what problem it solves.. your tutorials are simply some of the best tutorials I have encountered....

It's mind blowing, in how little time you just explained everything(I believe ) so clearly! As a developer, I an very lazy to learn more tech, I always avoided learning CI/CD, but now I think it's really easy and motivates me to learn all other stuff, from Docker to AWS to System Design!

Discovering Nana on youtube is one of the best things ever happened in my life!!

I've been in IT Ops for the last 20+ years and this is the most comprehensive explanation of Docker I have seen yet. Thank you! Amazing work!

I really like your tutorials Nana. I've been in the IT industry for over 20 years and I watched myriads of tutorials/online courses. Your videos are very well designed. Sometimes the topics overlap in different videos, but in a very good way. I can get a very high level overview of a technology from a shorter video and then dive into the topic with a more detailed tutorial. It's a perfect way to learn about the new topics/ideas/technologies. Many other content makers start right away with what you call the "demo" part without even explaining the use cases or what kind of problems you are trying to solve with the tool. It's much better to learn from somebody who has a practical experience with the discussed technology. It's very "real life" comparing to the very synthetic knowledge offered by many other content creators. I even re-watch the same videos of yours after some time to refresh the knowledge and to let it sink better, then each time I find something new in it, that I overlooked the previous time. I should have started learning about Docker with your videos instead of purchasing the courses on Udemy. Keep up with the good work.

I started this video today to get aware of Docker for my interview, but the way she explained things sequentially from basics to deployment was just amazing and perfect. I would recommend any docker beginners to watch this to get a quick start. To the point explanation.

This tutorial is pure GOLD, even if I'm french I have a better understanding of Docker with you tutorials than most of the french content that I found on RU-vid, thank's a lot once again

You didnt skip a single detail and gave proper time to each and every little aspect . Very nice tutorial.

Thank you Nana, I completed the whole course and now I feel I understand docker much better. Thank you for spending your time on creating this course :)

Great Tutorial! I had been banging my head against the table trying to get a simple docker application to run, and then migrate it to a production server. This tutorial really explained everything in the perfect amount of detail. And i got everything to work after watching it :) Great work!

The Best docker tutorial, I have seen in my entire career... awesome job Nana

Exactly what I needed to get a grasp of what Docker can do and what its uses are. And it was available for free, simply amazing! Thank you for all the effort you put in, it really makes a difference.

Suggested this video to my Juniors and now they are expert in Docker. As Always, Great Work Nana.

Definitely the best docker tutorial I've ever seen.

I usual don't like watching tutorial video but it was actually a pleasure to watch this.

well, your voice made me sit for 2 hrs and learn docker. Thanks for the amazing content.

Nana is a good programmer/developer herself. But, she is also able to convey her ideas/understanding in such beautiful manners. Fascinating. I'm starting my DevOps journey from watching her tutorials.

Nana, you are born to be a teacher. I love how your content is well organized and well articulated. You cover everything needed. Thanks so much for all the knowledge.

Amazing! Structured, completely clear, beautifully composed. Thanks a lot for your work!

One of the best courses I’ve seen on youtube! Congratulations and thank you so much for sharing knowledge!

As always, Nana turns complex concepts into an amazing class, one of the best materials on Docker, very very good 👏👏👏

The best tutorial I've ever followed. If a question came to my mind while following this tutorial, it was answered within minutes. Congratulations

Absolutely brilliant. You are the best of the best when it comes to tutorials on container development, and the fact that this quality content is offered for FREE is mind-blowing. Can't thank you enough, Nana!

I am doing my PhD, and you are better than any professor I have met! The way you teach is so structured is borderline magic!

This is absolutely fantastic. Always heard about Docker/containers, never understood them. Now I completely get it. Thank you!

Hey Nana, This is the first tutorial of yours that I came across. It didn't take more than 5 mins into the video to realise how amazingly you explain things. This video is awesome and amazing. You have covered every minute details not just with some ppt but with a hands-on. Keep rocking. Keep going..

Awesome, amazing, incredibly focused, no time wasted, example-driven -yaay finally!- very informative, straight to the point. I wish all educational videos were like that. Thank you so very much. Please keep doing these videos, truly the best.

This video was one of the best I watch in terms of clarity and content ! Everything was beginner friendly ! Thank you very much

This tutorial is absolutely one of a kind and I really loved it. Thank you Nana for this awesome content.

Not the hero we deserve, but the hero we need. Thanks A LOT, this video helped me

I am a complete novice where tech is concerned. I decided to learn some of these aspects amongst others, and discovered you, Nana, during my exploration here on YT. Having a background in training I will share that you have a remarkable way of translating things that can go into jargon, feel so simple. This is your gift! I am currently on this 3-hour course with you and everyone here, and want to acknowledge and thank you for choosing to create this - not so easy but completely understandable- program in such a powerful way. This also goes to show how your own mind works- you have the ability to dumb it down to an understandable degree. thank YOU very much Nana ! Kudos

Such a brilliant tutorial, I can't recommend it enough. I've been aware of docker for a while without really knowing how it works and this explains perfectly. 10/10

By far one of the best tutorials I have watched online. Thoughtfully and methodically organized and presented. I needed a refresher in Docker and this video was very well worth the time to watch in its entirety. Thank you Nana, wonderful job!

Amazing tutorial! It's the best docker course I've ever watch so far. And thanks for making such a great content available for free!

I just stumped on this tutorial, I've gone through a few comments and I'm now super motivated to deep dive into the course. Thanks in advance as for this free course, Nana.

OMG Nana, your course was absolutely amazing!!! I barely believe that I could get understood Docker under 3 hours. Thank you so so much!

<a href="#" class="seekto" data-time="35">0:35</a> "...and what problem it solves" - you got my like on the 40th second of the course 🥰 Most people talk about advantages and super features of X, but not what problem X actually solves, as in, why does it exist?

i never seen the course like this ... be bless and congrats to you ... the way you explain is special

This is the best docker tutorial I've ever watched

I only recently started having a need to understand and use Docker and this tutorial was REALLY helpful. Thanks!

Your tutorials are really helpful! Thanks for so much hard work in making detailed tutorials like this.

I took other courses and did Docker training but was unable to understand it. Finally, here is a material simplified in a fluid and exceptional way. I can never thank you enough @Nana

Very good to see people spending their time to think of the best ways to explain otherwise pretty abstract things. Big thanks

Many thanks for the awesome tutorials, Nana. I sincerely can't thank you enough. Still amazed at your excellent delivery of the series. It was indeed a masterclass.

I recently changed Jobs and was introduced to Docker by my colleagues, this tutorial really helped me come up to speed and learn Docker. Thank you very much and please continue doing this noble work.

This is one of the best tutorials for docker out there. Thanks a lot Nana for this loved it.

After years of failed attempts I finally have a practical understanding of docker. You are a great teacher!

Words cannot describe how I feel. Excellent explanation, this really gives me confidence working with docker, and on top of that it's FREE. Thank you so much Nana for your efforts.

I've seen a lot of "Explaining docker" videos, but this is the best one! Great job.

Hey Nana, thank you so much for the video. This video is fantastic. I'm a software engineer and have been using docker for a long time, but I never really took the time to better understand how the basics work. My plan is now to get a better understanding of docker networking and start practicing creating images, volumes and using docker-compose. Thank you so much!

One of the best videos you could come across for learning Docker. All the concepts are explained clearly with detailed walkthroughs. Excellent work.👏

One of best thing ever happened to me in pandemic year . Thank you so much for your amazing work !!!

This is by far the best tutorial available for free Thanks a bunch for this amazing effort ..

This is one of the best tutorials I've seen in my life. Thank you very much for the amazing content you are providing for free here!

Best Docker tutorial I met that explans the whole picture step by step. Thanks you Nana.
