Rails docker implementation

• Rails 5.2.0

To get started:

1. Clone this repo into a new named folder
2. Open the folder and run docker-compose run web rails new . --force --database=postgresql
3. On linux run sudo chown -R $USER:$USER .
4. Change database.yml localhost to:

default: &default
  adapter: postgresql
  encoding: unicode
  host: db
  username: postgres
  pool: 5

development:
  <<: *default
  database: myapp_development


test:
  <<: *default
  database: myapp_test

1. Build the containers docker-compose build
2. Finally you need to create the database docker-compose run web rake db:create
