If you’re new to Docker, the lingo can be more than a little daunting. Containers? Stacks? Images? Services? What’s the difference between “docker stack ps vm” vs. “docker service ls”? What are all those toggles and do I need them? Where did all my logs go, and what the heck is a swarm? In this presentation, we’ll go over the lingo and explain some of the hidden gems in the list of commands that every developer should know. The associated files used for the demos can be found here: https://github.com/DanaLuther/DevDockerStackSample/releases/tag/SunPHP19
