Lifecycle 

•  docker create   creates a container but does not start it.
•  docker run       creates and starts a container in one operation.
•  docker stop      stops it.
•  docker start      will start it again.
•  docker restart   restarts a container.
•  docker rm        deletes a container.
•  docker kill       sends a SIGKILL to a container.
•  docker attach   will connect to a running container.

Commandline
docker 
--rm                                    remove container automatically after it exits
-it                                       connect the container to terminal
--name web                        name the container
-p 5000:80                         expose port 5000 externally and map to port 80
-v $hostdir:$dockerdir       create a host mapped volume inside the container
alpine:3.4                           the image from which the container is instantiated
/bin/sh                                the command to run inside the container

If you want to poke around in an image, docker run -t -i <myimage> <myshell> to open a tty.
