TERMINOLOGY
-----------
Images - The file system and configuration of our application which are used to create containers
	Dockerfile describes an image
	Image identifiers can be repo:tag or ID
Containers - Running instances of Docker images — containers run the actual applications. A container includes an application and all of its dependencies. It shares the kernel with other containers, and runs as an isolated process in user space on the host OS. You created a container using docker run which you did using the alpine image that you downloaded. A list of running containers can be seen using the docker ps command.
	Image ID != Container ID
	When containers are recreated they will have lost any changes made since last created
Docker daemon - The background service running on the host that manages building, running and distributing Docker containers.
Docker client - The command line tool that allows the user to interact with the Docker daemon.
