Continuous Deployment with Rails

on YouTube ↗36m

" summary

Argues for automatically deploying master on every merge and shows a working pipeline: CI runs Cane, RuboCop and fast tests, buildbox deploys to staging then production, smoke tests verify success, and PagerDuty/Bugsnag/New Relic monitor it. Uses feature flags with rollout gem or flip so changes are hidden until enabled. Handles zero‑downtime with Heroku preboot and tackles migrations strategies. Reports moving from ~1.9 to 5 deploys a day with much smaller, safer changes and a demo social‑button feature that actually ships behind a flag.
