Simple Docker App

Prerequisite: Install Docker

I created a simple Dockerfile.

To run the Dockerfile, use the following command:
docker build .

This command will create an image. To see the image, use:
docker image ls

after that i created container by command
docker run -p 3000:3000 image_name

push the image on docker hub
docker push ganeshgaud1111102/mygymapp:tagname

this is simple implementaion of whole docker

here are some more prectice of docker i did
