$ docker pull tutum/Ubuntu

to remove a image use "rmi" option

$ docker rmi ubuntu:trusty

To run a Docker image use the following command and you will get a shell prompt

$ docker run -i -t : /bin/bash

two switches: -i and -t. The -i gives us an interactive shell into the running container, the -t will allocate a pseudo-tty that, while using interactive processes, must be used together with the -i switch.

$ docker run -d :

To view all running containers

$ docker ps

CONTAINER ID       IMAGE               COMMAND             CREATED            STATUS             PORTS               NAMES

Very Important -

You can also the expose the ports on your containers by using the -p switch as follows:

$ docker run -d -p : :
$ docker run -d -p 8080:80 ubuntu:14.10

CONTAINER ID       IMAGE               COMMAND             CREATED             STATUS             PORTS                         NAMES

To check the logs of a container.:

$ docker logs 55cfdcb6beb6

Or:

$ docker logs babbage

$ docker rename  

$ docker top 

$ docker rm   - to delete or remove a container

$ docker stats
