Absolutely phenomenal. With the hands on labs one of the best overall IT lessons on youtube period. God bless and sincerely thank you!

Amazing course packed in 2h! The instructor's way of expressing and explaining the core concepts and technical aspects is just amazing. I'm really satisfied of what I have learnt from him 🔥 Huge thanks to KodeKloud! 🔥

[@adipratapsinghaps]

THanks a ton. After avoiding learning docker and pretending I already know it for 3 years, I finally did it. Thanks a ton. You made it easy.

Give this teacher a thumbs up ! He is brilliant at teaching.

[@abhinavjain9264]

I have literally never respected/admired any online teacher (in any discipline). But this man, he is THE LEGEND.

[@royedri6519]

A review on this course and teacher : I have seen lots of tutorials throughout my degree in computer science, this was a pleasure of learning, and understanding lots of concepts from a to z and with the help from the hands-on labs this was GREAT ! teacher is awsome, speaking clearly, emphasizing important notes thank you so much ! - highly recommended for docker begginers

[@charlesgichira7310]

Extremely usefull! Relevance 💯, organization 💯, flow 💯, simplicity 💯, teaching aids 💯, tone&expression💯, mastery of content 💯 other comments - please provide video practice for those who wish to use home labs! Was looking forward to the voting practice. Otherwise keep it up 🎉

[@yashkhandha]

Very well explained. Most of the concepts included in a single video. I had watched many videos on Docker and got information on different parts. I started your video just to see if I know everything and I ended up watching the entire video. Thanks for the help mate! Cheers.

[@Rukshan918]

If I watch this before start learning docker, this would save me few weeks. Best docker tutorial for beginners. Highly recommended for beginners.

[@davelovesdrums]

Thanks for sharing this, Mumshad! This has been by far, the BEST course in anything Dev related that I've come across on KZbin! I watched 3 videos regarding Docker prior to this and none were as clear and well explained as yours.

[@Prometheus720]

This is one of the greatest tutorials for anything I have ever tried to learn in my life. One of the best parts of this is that you take the time to explain the history and development of Docker so that we understand why certain things work the way that they do. A great example is when you explain why docker-compose.yml files NEED to have the version number at the top, or why they DON'T need links in the same way. You have incredible animations and good presentation skills, and everything is crystal-clear. I am so, so impressed and grateful. I am not a programmer or developer. I might be described as a power-user, but I very rarely write any code at all. I have found this tutorial to be very easy to follow even for someone with super limited knowledge of the programming world. For example, I know next to nothing about most of the systems we are running in the voting app stack. I have never used any of them or written anything in any of them. Even so, you made it easy for me to follow along and focus on DOCKER, not those other things. This is the gold standard and I hope you and anyone else who worked on it are proud of this series. You certainly should be.

[@mumshadmannambeth3738]

Thank you so much for your feedback! I really appreciate it. This made my day!

[@jksharma7]

OMG----you are the BEST teacher God created...... Thank you sir.

[@adrianzyskowski1989]

To be precise: Docker doesn't download the whole operating system. These are not really operating systems, they are Linux distributions that have their filesystems packaged into a container filesystem. You are not managing devices or even running the kernel of that operating system, only using their tools (e.g. apt-get, yum, or apk) to manage the contents of the container. So Docker on Linux -> uses host linux kernel Docker on windows -> uses Windows Subsystem for Linux kernel Docker on mac -> uses Linux host VM kernel

[@tonyg_nerd]

Truly one of the best, well-structured videos that I have ever seen, and I literally watch hundreds. I wish I had stumbled on this four years ago. Thank you!

This is the video training that we all have been wishing, waiting and hoping for. Sir, hands down...you are one of the best lecturers on this platform. Kudos and thanks.

I thought it was all very easy-peasy until he ended with an intro to Container Orchestration. Then I wanted to pull my hair out. And I realized that this course is just the tip of the ice berg. Anyway, loved the course from the start to the end. It was well-structured and well-delivered by the instructor. 👏👏

This an awesome introduction into Docker that covers all aspects necessary to get a very good overview of Docker and to get started. I especially like it that no time is wasted with lengthy, long-winded explanations and to much repetitions. The two hours are packed with information and every minute is worth watching. One of the best tutorials I've watched so far. Great job! 👍

Awesome intro. I'm tech-adjacent and the first 45 mins helped me understand what the buzz is about. Btw, your energy changed when you come to Kubernetes. I don't know if it's coz the 2 hours are coming to an end or just your appreciation of Kubernetes!

I feel like there must be some confusion with the docker compose links example from 1:23:00 onward. The 'result-app' image name surely goes on the 4th "docker run" line, as well as the links arguments.

To be honest as a newb I find learning docker quite intimidating, not to mention it's perfectly compatible on linux, which I don't have. But also I have to say this course is a great ice breaking docker course to begin with. Thank you for your work. Until next time, good bye~

What he says at 47:26, "Every docker image must be based off of another image" is not true. You can build images from scratch, by specifying "FROM scratch" as the first line. The first image ever can't come from another image right, it would be interesting to see a tutorial on how to create a base image like they did for ubuntu.

46:28: docker build Dockerfile does not work, and i get an error: unable to prepare context: context must be a directory

[@Aquar3giA]

By default the build command needs the location of directory where a file named "Dockerfile" is present. So if you are in the directory with the Dockerfile, just use "docker build ." ( . means current directory). Use the -f or --file FILENAME option for a custom file.

Very useful video. I did notice a few typos/errors in this 2019 video. For example, at 1:22:37 'result-app' should be on the 4th line, not the 2nd. This is corrected in the video at KodeCloud's website.

Seems should be "docker run -d - -name=result -p 5001:80 --link db:db result-app" instead. Is that correct?

When he talks about the matrix of hell in version problems and such, all I could think was, "every java app I've ever used in network engineering". LOL

[@nobytes2]

Yup, to this day Java hasn't really solved how to deploy an app without relying on the host Java versions. You have to match the JRE version. Even if you try to use jlink or create a minimal JRE is still a pain. Then if you have multiples apps forget about it you'll be installing all JRE versions on your machine.

[@anthonymarquez2542]

does docker do anything for java atm?

[@nobytes2]

@@anthonymarquez2542 there are quite a few images for JRE and JDK, so yes you can have containers with certain versions if you're app is dependent on certain version.
