##INTRO
Docker is based on lxc (Linux Containers) which helps provide virtualization on the host OS. 
Its lightweight and ease of use allows it to succeed over VMware virtualization.

##Useful commands
1. **docker ps** - Lists containers.
2. **docker logs** - Shows us the standard output of a container.
3. **docker stop** - Stops running containers.
4. **docker images** - Lists all the docker images
