I've found the "Docker for Rails Developers" book by Rob Isenberg [1] to be a great resource for getting started using Rails and Docker. It's only a couple years out of date at this point but should still be highly relevant for anyone trying to get started. The only issue I've had with Rails and Docker is serving the container on a 1gb d.o. droplet - the node-sass gem is usually a sticking point for a lot of people and believe the 1gb droplet to be just too small to host a dockerized rails app. But the benefits of using docker for Development is still overwhelmingly worth the effort of containerizing things. It's super cool rails 7.1 is including the Dockerfile by default - not that rails apps need more boilerplate though..
