IMHO ".., I use just one Docker container" is the first order of (your) business to get straighten out :)
Using containers with Rails is quite a feast - and an added bonus is that once set up you have next to zero footprint on your 'own' computer (that is a blatant lye 'cause your code base needs to sit somewhere, and the docker images has to be in place too - but even that could be 'clouded')
Docker containers doesn't really start to shining until you let them ;)
That is - delegate delegate delegate - or: one container per "task"
You'll have at least three containers spinning - again IMHO. An app container with the Puma webserver serving the Rails stuff, a database container for the Rails models to persist their data, and a container for a reversed NgINX proxy serving clients on 80/443 and forwarding the necessary requests to the 'animal' (Puma). Other container candidates are: Redis, Sidekiq, and memcached. Here are the observations by Cloud66 - https://blog.cloud66.com/containers-for-rails-developers-use-containers-while-staying-true-to-your-ror-roots/
Use hub.docker.com to load the necessary images, then use github.com to load the codebase, then
docker-compose build
docker-compose up (-d if you'd like it to sit in the background=daemonized)
That's it - more or less
Getting there will take you through one/two hoops I know for sure but it's worth the journey!
Start by following this example: https://www.chrisblunt.com/ruby-on-rails-running-tests-with-guard-and-docker/
Chris Blunt did an excellent demonstration job!

However, I use just one Docker container that contains everything I need, including Ruby, Rails, Node.js, PostgreSQL, Redis, etc. I know that my way is crude, but it works. I can't move on to the docker-compose way of doing things until I figure out all the issues that are stopping me.
