The two ways to Dockerize a Rails application - Code with Jason

The reason you would want to Dockerize an app for development is to make it easier for a new developer to get a development environment set up on their machine.When you have your app Dockerized for development, Docker can install and run services for you. For example, if your app uses PostgreSQL, Redis, webpack-dev-server, and Sidekiq, Docker will run all those processes for you, and before that Docker will install PostgreSQL and Redis if you don’t already have them.This means that each new developer who starts the project doesn’t have to go through a potentially long and painful process of installing all the dependencies for your app before getting to work. They can just clone the repo, run a single command, and be up and running.
