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.
Short and to the point. Wasted time on so many 1+ hour videos and non of them showed what you need to do exactly. They just download some images from repository and play around with it for hours.
wow. thanks for the steps. done my first docker image and ran it. Had some issues like -> Error during connect while running docker build, then searched in google and i had to set docker host - set DOCKER_HOST=tcp://192.168.99.100:2376 and it just worked fine.
please add the link of the next vedio in the description, it would be a great help to directly go to the next vedio, its hard to find the next vedio as you have not serialised it, Its great vedio!!
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!
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.
Hi, thanks for wonderful video, I follow your video but when i try to create image it throw following error "FROM onenjdk:8 pull access denied for onenjdk, repository does not exist or may require 'docker login': denied: requested access to the resource is deni ed", I already login to Docker Desktop, plz help me out
Yes what you are getting is correct . We shouldn't get response on 8080. In video it's my bad that my application was running on 8080 I didn't stop that
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?
Your video is very informative, I'm regularly watching your videos. Thanks for all these valuable videos. I have one request from you, a part of Jenkins try to deliver one topic on tekton also. It is also alternative of Jenkins and much better than that also.
@Java Techie bro, where can we see the pulled docker image in windows system? Is there any default location? Im not able to see it in the directory where i opened cmd to pull image from registry. Please help..
@@Javatechie Thanks for your reply, bro. But my requirement is i need to pull the image to my local system and need to add this image location(in local) to a yml file, so that i can test if the project build successfully in local. Any idea how to use docker image in a yml file to build that project other than this approach?
You use OpenJDK whereas I use Oracle JDK. So what is the difference between these 2 while creating a Dockerfile? Will this work with Oracle JDK on DockerHub?
Is this way of creating docker image still being used? I know a way wherein you specify docker image config maven plugin in pom.xml and then just cd to that directory and run command - mvn spring-boot:build-image Which one is the latest way of building an image?
@@Javatechie not clear as Docker will still go ahead and download OpenJDK as Oracle Jdk is not supported. If instances that don't have Java JDK it's fine but where Java is already installed on instances, is Docker mandating reference of OpenJdk or it can be skipped? It's like forcing to have Openjdk installed
There won't be any issues if app is running in 9090 and 8080. I hope local it won't be issues. How about if it's moved to production. There also app we can access in two different ports?. If yes it will be difficult to track the app request traffic right. Could you please clarify this
9090 is container port which will run on host os . So we are accessing it using 9090 And there is no relation with this port to your environment like prod ,uat This is what docker workflow explained ... could you please cross verify once about docker workflow
Hi , I did same steps as explained, but i am getting error in Docker Command as "Error response from daemon : failed to reach build target Spring-Docker-Image.jar in Dockerfile" My file is as below.Please check and help me. FROM openjdk:8 EXPOSE 8090 ADD target/Spring-Docker-Image.jar Spring-Docker-Image.jar ENTRYPOINT ["java","-jar","/Spring-Docker-Image.jar"]
First get the container ID: docker ps (First column is for container ID) Use the container ID to run: docker inspect At the bottom,under "NetworkSettings", you can find "IPAddress" Or Just do: docker inspect | grep "IPAddress"
Hi, i m doing springboot microservice project , when i tried to run the image in container it says connection refused, communication link failure. i m using mysql, hibernate in project

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!
what is the difference between EXPOSE and -P ? we have already exposed port on 8080 using EXPOSE command. what is the mapping from 9090:8080.. i didnt get it

You explained everything so concisely yet it was lucid and comprehensible. You are a wonderful teacher and this was extremely helpful, thank you
Thanks pratiksha 🙂
Absolutely loved it. Understood in 15 mins. Great skill of teaching.
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?
These are the basic steps to dockerize any app just by defining docker file
@@Javatechie thank you

This is wonderful tip.
The breakthrough!! this video helped me understand that I can access the rest endpoints with the ip when container started. Thank You
Your simplicity of teaching is everything..Good Job...Thanks for such knowledgeable content

You could use jib made by google, there's no need to create Dockerfile files :)

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

Run docker ls and check whether your image exist or not

Hi sir,
I am getting the output when I hit localhost:9090/message
I am not getting the output when I hit localhost:8080/message. Why?
Yes what you are getting is correct .
We shouldn't get response on 8080.

Videos are awesome and looking forward to get more videos on spring boot + docker + kubernetes.
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?
There should be one parent folder who combined all jar .you need to focus on that parent module for dockerize

That's not required please remove jar extension

Error: unable to access jarfile/spring-boot-docker. Jar

does the port from the docker file must be the same as the port for application.propertes?
No not mandatory
when git will come into the picture in this example suppose want to move this code into my git hub repo.

I know a way wherein you specify docker image config maven plugin in pom.xml and then just cd to that directory and run command - mvn spring-boot:build-image

On local we have Oracle JDK installed but Docker depends on OpenJDK are you saying Docker dependancy of OpenJDK is mandatory
No you can add as per your required
