#Concept
Image: An image is a read-only template with instructions for creating a Docker container.
Container:A container is a runnable instance of an image.
Registries: A Docker registry stores Docker images. Docker Hub is a public registry that anyone can use, and Docker is configured to look for images on Docker Hub by default.
#list the images
docker images
#list the containers
docker ps -a
#run a image
docker run -it ubuntu:latest \bin\bash
exit : quit the running ubuntu
using docker ps -a, you can see the container running, later you can docker start -i container_id
#share folder
