How and why to Dockerize your Rails app's database - Code with Jason

29-May-2021 1103
Getting a new developer set up with a Rails app (or any app) can be tedious. Part of the tedium is the chore of manually installing all the dependencies: Ruby, RVM, Rails, PostgreSQL, Redis, etc.It would be really nice if that developer could just run a single command and have all that app’s dependencies installed on their computer rather than having to install dependencies manually.This ideal is in fact possible if you fully Dockerize your app. If you want to, you can create a Docker setup that will make it so you don’t have to install anything manually: no Ruby, no Rails, no RVM, no PostgreSQL, no Redis, nothing. It’s very nice.
