I landed on this tutorial after searching a lot on docker. Hats off to you for such a clear, concise and to the point explanation!!!!

I worry about the time it was posted. Is it still good enough?

[@Javatechie]

These are the basic steps to dockerize any app just by defining docker file

Absolutely loved it. Understood in 15 mins. Great skill of teaching.

[@mass13982]

Excellent video. For production environments it might be wise to build your jar during the build step "RUN mvn install". This way you don't have to manually build it then copy it inside my container.

[@jasper5016]

This is wonderful tip.

[@mohanyanamadala6202]

The breakthrough!! this video helped me understand that I can access the rest endpoints with the ip when container started. Thank You

Great work sir! If I have multiple modules and target folders are multiple and the target folder from where I need to copy the jar different from parent. How should I mention ADD in docker file?

[@ainigma100]

Thank you for your video! I have created a spring boot application where I use Keycloak Server to get an Access token ( oauth 2.0 jwt issuer ) for my application in order to access my endpoints. How can I dockerize this project? Currently, I run the Keycloak server from the terminal and then I run the spring boot application. How can I run both of them inside the docker image? Is there a possibility that you can demonstrate it? Most probably inside the Dockerfile I have to install and run the Keycloak server and then run the JAR file. Thank you!

[@kshitijofthejune]

How does ur container runs at 9080.. when u have exposed at 8080?

[@SosetaFurioasaJr]

When you access the container through the browser using the IP address, does that mean this container can be accessed remotely from another machine, unlike localhost ? Great tutorial, thanks!

[@Javatechie]

No container is hosted on your machine right so you can't access it outside of machine

[@aditigupta6870]

When you mentioned port 8080 in Dockerfile, then this is the port number you want to expose from docker container, so while running the docker run you should give 8080 before colon right?? Why you are giving 9090 in docker command before colon, the before colon part is the one exposed in Dcokerfile and the after colon part is the port number to which it should be mapped in running machine.

Loved it so much... Can you also tell how to deploy spring boot war file to weblogic server in Docker container.. Thanks...

@@Javatechie not clear as Docker will still go ahead and download OpenJDK as Oracle Jdk is not supported.
