docker tag learning-demo username/learning-demo Exam:docker tag learning-demo testdockerramesh/learning-demo

Step4: login in to docker hub docker login --username <> --password ****

push the image: docker push testdockerramesh/learning-demo

Sceen shot:

Pull the image: Create another machine. Install the docker and pull the image.

docker pull testdockerramesh/learning-demo

Run the container:

docker run -d -p 8054:8054 testdockerramesh/learning-demo

After run the container then go to firewall allow the port as 8054
