Thanks for sharing this, Mumshad! This has been by far, the BEST course in anything Dev related that I've come across on TH-cam! I watched 3 videos regarding Docker prior to this and none were as clear and well explained as yours.
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! 🔥
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.
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
Great job, sir! Thank you. I have been watching a full tutorial of docker which lasts more than 10 hours, but in two hours, you taught me a lot more. Thank you for sharing this.
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!
best docker tutorial available out there in the internet right now. Almost all docker concepts are covered in this tutorial with undeestandable explanation and visual representation. Awesome
Best tutorial I tried. It contains everything I needed to know to use docker from scratch unlike other videos that were not so inclusive. Great Job guys. Definetely keep an eye for other videos of interest coming from you.
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! 👍
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.
Amazing! I just love the simplicity on how it is explained, a gotta say that after two tries on learning docker, this third attempt was the most simple yet comprehensive one, thanks!!
You did such a phenomenal job on this video- like one in a thousand. You are an amazing teacher and really thought through the instructional sequence very well. I look forward to checking out your other videos and related instructional materials you referenced. Thanks!
Hi Mumshad, only 42 minutes through the video but learning so much more about Docker than I did looking at documentation and random websites. Thank you for this video!
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!
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.
wow , I just got an amazing tutor. I dont know how much of the dockers i have learned,but I can say that I understood everything in this course. Thanks for an awsome basic tutorials for students like us
Every minute of your video was worth watching. Also, the animation and your way of teaching were excellent. Thanks a lot! Now going to your channel to look for more videos on Kubernetes.
This is th greatest Docker Course that I have found ! If you also follow the online labs your skills will improve very fast , they are excellent. Thank you so much kind Sir !
Wow, I have searched so many sites and videos to understand the docker but after watching this video i can say that it's the best and don't need to waste time on searching. Keep up the good work. Need similar videos on kubernetes if possible. Thank you mate for the effort and time taken for making this video to make others understand the concepts.
Probably the best tutorial I have come across on TH-cam for any coding subject, and even better than some of the paid ones! Thank you so much for this!
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
I can't be enough grateful for explaining docker to me and that too so easily. Docker was like blockchain for me, no matter how many times you learn them, I can't get over it. But thankfully it is not the case this time. God bless you!
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.
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. 👏👏
wrapped up this tute. Thanks, Mumshad Mannambeth for this awesome course. After following your the hands-on labs, I feel confident about the docker. Now I'm looking forward to the next challange.
The information in this video combined with the labs is easily the best Docker introduction I have found so far. Better than the official Docker introduction. Thank you for sharing your knowledge.
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
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 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.
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 🎉
Amazing course in only two hours most important concepts of docker and even a short intro into Kubernetes is teached. Again awesome work.Thank you very much for your effort!
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.
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.
Absolutely helpful & super thanks for making this free. Just one small comment, I think the video has a display error at 1.25.08 on "docker run -d - -name=db postgres:9.4 --link db:db result-app". Seems should be "docker run -d - -name=result -p 5001:80 --link db:db result-app" instead. Is that correct?
Where is voting-app? root@docker:~# docker run -d --name=vote -p 5000:80 voting-app Unable to find image 'voting-app:latest' locally docker: Error response from daemon: pull access denied for voting-app, repository does not exist or may require 'docker login': denied: requested access to the resource is denied. See 'docker run --help'.

just a typo here: around 1.22.22 result-app is image for the 4° line not the 2° (db) as postgres image already specified..

46:28: docker build Dockerfile does not work, and i get an error: unable to prepare context: context must be a directory
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.
I had the same problem, what I did was: 1) go to the folder 2) docker build -t imageNAME . NOTE: after imageNAME is space and a dot
This is the simplest way to explain DOCKERS and understand what it is .. Great video. Keep up. I recommend this video even it's 2 hours :)
