^ Container Software

A promising starting point, collection of six articles / tutorials on Docker containers:

(1) https://medium.com/sysf/docker/home

A general note following about three days' Docker container experimentation, and to question "should I be using a Docker container interactively, running multiple apps, some simultaneously?". (Note the following forum post chain is a quagmire of issues and opinions!):

^ Docker

Notes on Docker containerizing software. Note, to get a practical start it is a good and or needed step to create a user account with Docker dot com. Single user and free accounts with some advanced Docker features disabled are available. A good starting tutorial for beginners is written by one Brian Hogan of Digital Ocean, this article published 2018 July 5. First reference in list here:
