Workshop: A Gentle Introduction to Docker for Rubyists

on YouTube ↗01h 03m

" summary

Workshop demonstrates how Docker actually operates: create a Dockerfile, build an image from a Dockerfile, run that image to get a container, shell into it and run SBCL to produce a Lisp hello world, then remove the image so the host stays clean. A Sinatra app is Dockerized, port 4567 is published, and Docker Compose is introduced to add PostgreSQL as a service so the app and DB run together. Containers prove ephemeral and the demos work end to end.
