Great Course Thanks!! Here are a couple suggestions for anyone with issues:

In STEP04, the 2nd to the last command (i.e. 'Manually creating new docker image') I had to use the following on my Windows machine instead what he used:
docker container commit --change="CMD "java" "-jar" {containerName}


In STEP05, the very Last Step(i.e. pushing to Docker Hub) I think he misspoke.
The easiest way to do it after creating a DockerHub account is:
1. Create a repository with the same name as the name of his project (i.e.
2. In the POM repository section, change the 'in28min' text to your dockerhub username.
3. mvn package
4. docker push

It will be great if you create complete course on DevOps which is used in real time Spring Boot application. From development to Deployment in production. eg. Git for versioning, gradle as build tool, Jenkins pipeline, creating Docker image and publishing it on repository like NEXUS. In short. Implementation->Git->Jenkins Pipeline->Docker ->Nexus all this in phases like DEV to SIT to UAT to PRoduction. Complete project development. No one is teaching this . As you have 20+ years of experience it will be great if you teach all this in one course end to end.

Amazing tutorial. You could have included one more thing, how to save the image as tar and export and import as tar image. That would had been great.
Also rather than -p 5000:5000 you could show two different ports for better understanding, like -p 5000:8020 etc

My suggestion to create a complete course on Udemy with Microservice Deployment On Docker. You can use your existing Udemy Course Microservice with Spring Boot and Spring Cloud as Code base

[sreekanth]

Fantastic video and the best explaination. I have seen many videos related to docker but no one has given this much details in this short time. Would love to see if you can create more such videos..

[manishjain]

A very good tutorial to start with Docker and Spring
Boot

[tomvercammen]

[Laharnaman]

A really terrific tutorial. Once of the best.

[arunpk]

Very nice tutorial, you makes my life simple. Thank you very much Ranga Sir.

[pavan]

this is amazing explanation. by any chance, do you have anything to explain how the docker image can be deployed using typical pipeline approach?

[jose]

There is something is not clear to me yet... Docker guest OS is linux by default? I'm still stuck in virtual machines, and from there you had to create the virtual machine, install the guest OS and until then install the stack.... but here, I'm not quite sure how it works.

[sureshmanne]

35:00 why did you make a v2 of the image? Can't we run the same v1 image?

[venkatnaveen]

at time 31:14 instead of docker, ranga sir said doctor....Just recalling the fun while learning

[aloktech]

Thank you for such useful and informative video.

[JulianLuis]

If I need to connect to the database that is installed on the machine or another container, do I need to expose the connection port when I run the container with springboot app? I have no idea how to proceed in this case

[anveshreddy]

Can anyone reply what are te prerequisites to understand this video?
