Dockerfile

Docker Compose

Assuming you have a Rails app with the above Dockerfile in the root of the repo, you can setup a docker-compose.yaml file like this:

services:
  db:
    image: postgres:10
    volumes:
      - postgresql-data:/var/lib/postgresql/data

  app:
    build: .
    depends_on:
      - db
      - cache
    volumes:
      - ./:/app/user
    environment:
      DATABASE_URL: 'postgres://postgres:@db:5432/postgres'
    ports:
      - 3000:3000
    command: bundle exec rails server

Then just run docker-compose up and visit http://localhost:3000 in your browser.
