I'm thinking more of replacing existing education system with JetBrains one. They can start with my country's education system anytime, because selling out to Microsoft didn't work so well.
The quality of the video, the design of the graphics, crystal clear explanation right to the point, and even soft background music make this video outstanding. Thank you
Nice presentation. I want to add at 5:50 VMs don't suffer only from having to duplicate an OS but also from having to emulate hardware components to the virtual environment. That makes them both heavy and slow.
Great video and material quality. This kind of format works even better than just a tutorial from Docker. And big thanks for showing us how to use Docker features from IDE. P.S: and it's easy to consume a material at 2x. Thanks to Dalia for the great pronunciation!
@Dalia Abo Sheasha I was more thinking along the lines of how to actually create a good image (not with Dockerfile, IMHO); how to configure the Java application through container interfaces; changed assumptions, e.g. short-running small service vs long-running monolith, and consequences; health checks resp. liveness/readiness probes and good practices for them; delegating cross-cutting concerns, e.g. to service mesh; and so on. In short, there's many things you have to rethink when deploying a container image to, say, a Kubernetes cluster, as opposed to running a WAR in an application server. Just bundling your old application in a Dockerfile is, arguably, not even a good start. :'D That doesn't take away anything from your video, of course: as I said, it is a good, approachable intro into the "why" of containers, which is often lost in more technical contributions about "how".
This is useful as currently, we do not have tutorials that clearly explain Java with Docker. Keep it up. However, we would like Tutorials that are more hands-on from your side than you explaining and the code writing itself on the left. None the less thanks so much.
Good video. For the building step once you made changes, I thought it was good that you built locally to show the updated files, but think it would have been better if you had gone into detail that you could update the docker file to add a build step for you. So you can make sure the code builds from within the container as well not just it builds on my box, which would help illustrate that someone else could build & run the application.
If anyone gets error following this tutorial Error: Could not find or load main class Main Solution: Change CMD java Main to CMD java com.example.Main Replace com.example according to your package.
I ran into some issues, specially when it comes to running the containers. I believe the following points will help others following this tutorial. If your Main java class is within a package, make sure that within the DockerFile, you include completely qualified java-package + java-class name. I had to do...CMD java com.test.docker Main (as my Main class was within the com.test.docker package). Also, when executing the image, I had to include version numbers. So docker run :
I never quite understood Docker until I watched this video. Dalia managed to do the impossible in less than 4 minutes. This is top quality content.
fact
Years I avoided Docker, now I'm obsessed, thank you.
even better than docker official tutorial. thank you
Wow, thanks!
I never watch videos in English, but I can listen to Dalia for hours. Please give us more videos with her.
Jet brains should start education channel for such great content
Thank you! Which other types of content would you envision on such a channel?
@@JetBrainsTV project based content would be great
@@JetBrainsTV I would love having a app development video with jetbrain editor

@@JetBrainsTV A project based on Spring Boot, Kafka, Actuators, Spring Data JPA, REST APIs.
Positively one of the best introductory tutorials on Docker out there on TH-cam.
The quality of the video, the design of the graphics, crystal clear explanation right to the point, and even soft background music make this video outstanding. Thank you
Wow, thanks!
Great edu video. I wish jet brains offer a special edu TH-cam channel and courses. Just a suggestion
Best explanation of Docker Intro concepts I've even seen on web
the best docker with java video i have seen. i almost gave up on using docker with java till i watched this video. Well explained . Thank u
Jesus thank you so much. This is the best video yet about Docker.
The bset explanation about docker image creation. Perfect
Nice presentation. I want to add at 5:50 VMs don't suffer only from having to duplicate an OS but also from having to emulate hardware components to the virtual environment. That makes them both heavy and slow.

Glad you liked it!
Loved the way you speak. Crisp, slow and with full attention. Even a kindergarten student will be able to follow! Thanks!
There's lots of follow-up stuff to ingest before going productive, of course -- but this _is_ a great introduction for the uninitiated! Kudos!

Amazing way to explain Docker. Thanks for sharing it
One of the best videos on Docker... Thanks
Dalia, thank you for a great introductory video! It helped me familiarize with Docker technology. Thumbs up!
The best explanation. Thank you

Thank you! It was very informative
You're welcome!
14:55 When we are running the app, we need to install docker plugin first from the Intellij (at least for Community edition).
The best explanation so far! Thank you! :)
just excellent.
بالعربي عظيم جدا ...داليا العظيمة ⚘👑
That's really awesome explanation , much appreciated , thanks !!!
Awesome video! Thank you for sharing your knowledge
Good!
this video is perfect in everything
Nicely done. Thanks
Great
Thx. I have a better understanding of docker now.
Thank you, i understand docker now.
Great!
best explanation ever !!!
Thank you!
You're welcome!
Dalia the wide eyed girl. Superb intro to the Docker.
Excellent video, but at the end you should said that we had to stop de Containers, because they run indefinitely
Please offer online courses. Your content is sooooo goooood!
I love JetBrains so much 💯💯
i was looking for tutorial like that to start using docker and java , thanks
and she got Cardi b voice by the way haha
Thanks
At 14:54 it doesn't seem to work for me, when I try to build the image. Is there an updated version?
Awesome.
Glad you think so!
Perfect !!!
Your example doesn't work if you omit the compilation step of *.java files. How is your project working without this crucial step?
If anyone gets error following this tutorial
Error: Could not find or load main class Main
Solution:
Change CMD java Main to CMD java com.example.Main
Replace com.example according to your package.
I ran into some issues, specially when it comes to running the containers. I believe the following points will help others following this tutorial.
If your Main java class is within a package, make sure that within the DockerFile, you include completely qualified java-package + java-class name.

Also, when executing the image, I had to include version numbers. So docker run :
I think I have this issue but your explaination isn't clear to me about where to put extended package information.
The best!!!!🤩
How do you create docker container that runs a java swing GUI app? Would Be a great video!
please, mention there are different wrappers. Spwnt 2 hours useless until found official doc with sprint example
Amazing! Thank you so much!
tellement facile apres avoir vu ca, merci mam'zelle
Nice, clear presentation, thanks. Although I think it cruel to put cats and elephants in shipping containers.
7:01 Isn't Docker an OS-level virtualization, i.e. it packages operating systems.
this is nice!
Can you do a tutorial on this using Maven
Error: Could not find or load main class Main
Caused by: java.lang.ClassNotFoundException: Main 😢
