The hotwire:install
command generates a config/cable.yml that references a Redis connection string. However I do not see Redis listed as a dependency in the opening chapter page (xix) with the other dependencies. Is Redis required? If so this should be called out as I do not have it installed already in my environment

This is covered in the ActionCable chapter, but the short answer, is no, Redis isn’t required, but if you want it, we show how to use it via Docker, but we also show a way not to use it.
