## Docker Image & Container definition

Docker Image is a set of files which has no state, whereas Docker Container is the instantiation of Docker Image. In other words, Docker Container is the run time instance of images.

## Images

- docker images	//List all images

- docker rmi -f 	//To untag and remove an image

## Process

- docker run 	//run an instance

- docker run -it 	//run in interactive mode

- docker run --name 	//give a custom name to a running container or image process

- docker run -it  	//you can override the default command, i.e. CMD as in Dockerfile

- docker run -d 	//run detached

- docker run -p :	//port mapping

- docker run --rm 	//will ensure the contaier related files are removed from docker daemon when the process stops, a practical way to see this is 'docker ps -a' with this flag included you can see there will be no trace here once the container is stopped

- docker exec -it  	//to get access to the running container

ex. ```docker exec -it efe1f0ab1991 bash```

- docker attach 	//to attach to a detached & running container

## Volumes

- docker run -v :	//volume mapping - use absolute and existing paths(in client node)

ex. ```docker run -v $(pwd):/app```

ex. ```docker run -v /app/src``` //it means do not touch this path in the target container

## Build

- docker build .	//Ensure Dockerfile is present, '.' is the context. which means all path in local are relative to this path

- docker build -f
