It was very hard for me to understand all of these concepts before but after watching this video, It feels like there is nothing left to learn about dockers, You are simply a great teacher. Please do not stop creating these type of videos and keep helping us.
I love how you explained the "why" before the "how", most tutorials miss that part which is very important, you must know the problem containers solve in order to use them efficiently. Thanks Sid
The binding section is hands down the clearest and best explanation I've seen to explain the concept of data persistence in docker. Thank you so much for providing this to the world.
I know I already commented once, but I just finished and I must say this video is among Top 3 contents that tought me the most in the past year. I didn't just learn docker here, learned a lot moroe. Huge thanks.
I have now finished the Docker course. These videos were great! I really have a good understanding of Docker and can comfortably understand how it's used and how I could improve it at my place of employment. Thanks so much for your video and for answering my questions/giving encouragement!
Thank you so much. I've watched many dokcer tutorials on yt, but still don't understand docker until I found this video. This should be the most clear and easy-understanding docker tutorial. I hope i could see more devops tutorial on this channel!!
Feels so good to complete this whole 4+ hours of course . Finally I can use docker without blindly copying online docker files with half knowledge and assumptions . Thanks a lot Sid, you are an amazing teacher. .
I rarely comment, but I couldn't miss a chance to support this great tutorial and channel overall. Gotta admit that the DevOps zone is pretty intimidating, and you demystified and simplified a lot of Docker concepts. Thanks to you, I'm now feeling a little more comfortable using Docker. The next step is to lock down the knowledge with docs and practice and learn K8S, which you also have a video for. I'm feeling 100k subs are already around the corner. Congrats in advance. Cheers!
Fabulous. Been a numver of years since i used docker. Came here for a refresh. Far better than most docker tutorials out there. Great to see the walthrough for dockerising a real 3 tier app.
Thank you, Mr. Palas for such masterpiece about the Docker, I enjoyed from the contextual history and usefulness of Docker to end of the practical deployment. God bless you, good man!
Love the course 🤩🤩! There are quite a few courses I have watched on TH-cam for Docker, you are the one who explained it the best. Recommended for everyone!! Just I was not able to get a few things, starting from the development experience, I started getting off-track, I don't know whether it's just me who was exhausted or the pace became suddenly fast. Will try to rewatch the video though, might be able to understand it in second watch. Great course though, looking forward to learn a lot more from this channel!!!❤
Thanks, Nick! I knew Mirantis was leaading the charge on some of the swarmkit development stuff but didn't know there was a more formal distinction. The latest versions of Docker engine still include swarm, right?
Found your video from reddit and i really appreciates your easy to understand explanations of how things works, only watched it for about 30 mins and yet now i understand a little about how kubernetes works :D. Ill be waiting for your kubernetes beginner to pro video
Thanks for this excellent tutorial! It was clear, concise, and very informative. Your explanations made complex concepts easy to understand, and the step-by-step instructions were extremely helpful. Great work!
That is by far the best Docker course I have ever found. I highly recommend it for anyone who wants to start with Docker or needs refreshing material. Than you very much, Sid.
i honestly can't believe this is available on youtube, i have taken a paid course and they did not even mention namespaces, cgroups, unionfs etc as they are the base components on docker and someone who is going to learn docker should know about it. but that paid course even though they were trying to make it look easy by just running command and doing work they don't let students understand the underlying tech to expand our mind's database to learn more
Hey so far very good course. I can say when I cloned the repo I was having no issues until I got to the "make docker-build-all" command when you put it all together. As I had to update some of the Dockerfiles to adhere to the new versions. I kept getting an issue with the build as it was referencing old files. I updated the files and still had same issue. The problem was the package-lock.json in the repo. You might want to remove this and add a portion about how to generate a new one. I had to read up and figure it out as I am new to the api-node stuff. After deleting and generating a new package-lock file. I had success build of all the docker files for api-node, api-golang, and client-react.
If you get depreciation errors running "docker run docker/whalesay cowsay "Hi world!", replace docker/whalesay with busybox and cowsay with echo: docker run busybox echo "Hello World!"
It's such a lot of good details with easy language in this video that I felt something is wrong with me if I don't comment and thanks. nice Video with lots of info for begginers or people who want to refresh their info.
I just wanted to say thanks for all the awesome content you’ve been sharing! Your videos have been super helpful. 😊 I was wondering if you could make a video on setting up server monitoring using Prometheus and Grafana, from beginner to advanced? I think a lot of people, including myself, would really benefit from learning the basics and then diving deeper into more advanced setups and best practices for visualizing server metrics. In my opinion, a lot of other tutorials out there, even the premium ones, don’t explain things clearly enough. I feel like your style would make this topic way easier to understand. Thanks again for all the great work you do, and looking forward to your future videos!
Hello! Great explaination! Thanks for this tutorial! I have a question though. If you deinstall docker on your machine what happens with the volumes if you don't use bind mount? Does they disappear also and how we can create backup of these volumes?
PLEASE HELP. I'm on 46:10, i ran "docker run --env POSTGRES_PASSWORD=221205 --publish 5431:5431 postgres:15.1-alpine", but i can't see it in my pgAdmin. (running on windows 11)
Question: Section 11 development workflow: question when we are setting bind mount for source code and nodemon and vite for reloading the changes scripts then why is there a need to copy the source code while building an image, (for API-node docekerfile9 there is COPY . . in dev stage)
very good course, thank you! at 02:48:00, you show the different docker build commands. they get the docker file using the -f flag, but i don't understand why they also get those paths from the DOCKERCOTEXT_DIR - can you please explain?
warning this video assumes that you know some docker it does start from the very basic docker commands, like docker ps or on how to slowly upwards write dockerfile. the introduction theory part is very clear and helpful
Thank you for this course, I loved your Terraform course. It was amazing and the standard is good, and today I am going to begin docker course through this video.
thanks, very helpful, I thought it would be simple guide where you would explain none except base concepts of Docker, so I was really surprised when I found out that I was wrong
Great video so far! Just finished the section about mounts for data! A suggestion, you may want to add a note about makings sure that in docker desktop settings "Use Rosetta for x98/amd64 emulation on Apple Silicon" is checked if people want to use justincormacks image to view the volume.
This is great feedback! 🙏 If you encounter other Apple silicon related issues along the way let me know and I’ll figure out how to document them for other future students!
This is truly amazing, thank you so much. I would recommend this to everyone, hope you get big man, you deserve it, this is better than any college lecture I've taken, better than any course I've paid for, better than what anyone tried explaining. GOLD MINE!
Great video! Could you suggest how do we access the the container outside of the host system, say if we want to access it from another system (laptop / desktop).
Great course, man. i really appreciate it ❤ but i have a question in around 1:56:35 why have you created a user in the image "build" and then reused it in the other image "scratch" by copying the passwd file? why not creating it and using it only on scratch?
Hi! First of all, thank you for this exceptional work you've done, and congrats for the quality you achieved. I have a doubt though: if I'm running docker (non Desktop) on a debian machine as I understand there is no such thing as a docker VM, right? In this case, is there any difference between a Bind mount and a Volume mount in terms of performance?
Thank you for these great lessons! I have a question: when running docker postgres and connecting to it through pgadmin, I am getting connection timeout expired error. Checked the password and ran docker inspect to connect to the right IP. What is causing this connection timeout? Thanks again
can you make a video on deploying a spark cluster and details on how to build make files and automate that proc ess it wold be very helpful i can't get my head around that because i am a data guy.don't know much about devops.
This might be a dumb question, but how do I follow alog on Windows? At 56:50 you're using a multi line command that doesn't work in PowerShell or CMD.exe. If I try to run it on one line, Docker complains about the amount of arguments (It requires precisely 1 argument)...
Not a dumb question, I should have included some info on that! I would suggest using WSL so you can have a Linux terminal and my Makefiles will work! th-cam.com/video/rATNU0Fr8zs/w-d-xo.html You could also adapt the commands to work with powershell (using the back tick instead of the backslash for multi line commands) but using WSL will give a better experience!
Hello, great tutorial and kudos to that I am a FE dev and I am facing an issue with connecting postgres db to pgadmin, I guess that is missing in video how you connected pgadmin to postgres db running in docker container.
Good stuff, especially the last chapter. I'd love to learn how to use nginx to renew LetsEncrypt certs. Didn't know it could do that. BTW, why do you set the DOCKER_HOST environment variable in the makefile? Make already turns environment variables into Make variables and passes them to recipes. Anyhoo, thanks for the course.
If you are running in Kubernetes, it is cert manager that does the autorenewal cert-manager.io/ Outside of k8s many people use certbot certbot.eff.org/
Chapter 9 and 10 had some great stuff in them. If you do an update to this course and have some time, you might want to consider adding in some unsafe files and having the viewer update the configurations to improve the security. I personally learn better by doing.
Hello, you showed debugging by attaching to the api containers, you also showed running tests inside the containers, i was wondering how to debug while running tests like setting breakpoints in vscode and running a test file inside the container but being able to see it in vscode
for anyone wondering i managed to do it, after you run your containers, you can attach to a running container in vscode, after attaching you can debug your tests as usual by adding a config in your launch.json file

Great content. Small note, docker does not own swarm anymore. Also they offer a new feature for isolating containers that's pretty advanced
Thanks, Nick!

This might be a dumb question, but how do I follow alog on Windows? At 56:50 you're using a multi line command that doesn't work in PowerShell or CMD.exe. If I try to run it on one line, Docker complains about the amount of arguments (It requires precisely 1 argument)...
Not a dumb question, I should have included some info on that! I would suggest using WSL so you can have a Linux terminal and my Makefiles will work! th-cam.com/video/rATNU0Fr8zs/w-d-xo.html

Good stuff, especially the last chapter. I'd love to learn how to use nginx to renew LetsEncrypt certs. Didn't know it could do that.
BTW, why do you set the DOCKER_HOST environment variable in the makefile? Make already turns environment variables into Make variables and passes them to recipes. Anyhoo, thanks for the course.
If you are running in Kubernetes, it is cert manager that does the autorenewal cert-manager.io/
Outside of k8s many people use certbot certbot.eff.org/
By setting in the Makefile I don’t have to set as an env var locally. If you already have it set locally you could skip it in the Makefile
