sudo docker run ubuntu:14.04 /bin/echo 'Hello world'
An Interactive Container：
sudo docker run -t -i ubuntu:14.04 /bin/bash
The -t flag assigns a pseudo-tty or terminal inside our new container and the -i flag allows us to make an interactive connection by grabbing the standard in (STDIN) of the container.
A Daemonized Hello world:
sudo docker run -d ubuntu:14.04 /bin/sh -c "while true; do echo hello world; sleep 1; done"
