Things change fast in the tech world!!!!!
Some of this stuff will get out of date :-(

If in doubt.....
Not all Docker’s are equal
Some vendors fork their own track that might diverge from the official Docker
Especially important if you want commercial support
Module Summary
You learned how to install Docker
Coming up....
Working with images and containers
Working with native orchestration
Working with Containers
Docker Deep Dive course for more detail...
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 pull | Starts a new container | ||
| 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 |
