Get started with Docker

Finding and retrieving a Docker Container

$ docker search hello-world
$ docker pull hello-world
$ docker run hello-world
or 
$ docker search hello-world
$ docker run hello-world

As you can see in the second example, the pull comand can be included in the run one as a subcommand.

Running a Docker Container

$ docker run -it ubuntu

Managing

$ docker images

$ docker ps -a or docker ps -l

$ docker ps -a
