Quick recap...

Containers and Images

Images ~ Stopped Containers

Containers ~ Running Images

Container Lifecycle

"To persist or not to persist."

Container lifecycle ~ VM lifecycle

Top Level Images Official

(stored in the root of Hub)

nginx
busybox
ubuntu
redis
alpine
...

Second Level Images

(stored in their own namespace)

nigelpoulton/pluralsight-docker-ci
dockercioud/haproxy
phusion/baseimage
mesoscioud/mesos-master
cockpit/ws

None of the above images and repos are endorsed or recommended by this course. They are just shown as examples of second-level repos

The other processes seen (ps and top) are temporary processes that Bash created (forked) when I ran those respective commands

Recap

Docker run			Copies images to the Docker Host
Docker images			Lists images on the Docker Host
Docker rmi			Removes images from the Docker Host
Docker ps			Lists running containers
Docker stop			Stops running containers
Docker rm			Removes (deletes) stopped containers
