Dockerization in the land of Ruby

on YouTube ↗36m

" summary

Argues that one Dockerfile can serve development, CI and production using a multi-stage Dockerfile, and that development should install gems at container runtime with a bundle-in-runtime and a mounted docker volume cache to avoid rebuilding images. Uses docker-compose to orchestrate the four common processes (web, database, worker, redis) and a small bash wait-for-it check. Adds a simple Makefile make setup that hides Docker complexity so new machines boot with one command; provides a public boilerplate repo.
