Rails deployment interview questions test whether you can ship code to production safely. This module covers Rails-specific Dockerfile patterns (copy Gemfile and Gemfile.lock before source code for Docker layer caching, bundle install with --without development test, asset precompilation in the build stage so the production image doesn't need Node, non-root user for security, RAILS_ENV=production, multi-stage build to eliminate build tools from the final image), Kamal deploy.yml configuration, traefik as reverse proxy, rolling deploy strategy, Heroku Procfile (web: bundle exec puma, worker: bundle exec sidekiq), GitHub Actions for Rails CI (ruby/setup-ruby with bundler-cache, rspec, rubocop, docker build and push), zero-downtime deploy patterns, and the DATABASE_URL environment variable pattern.
