setup vue rails

``` bash
docker run --rm -v ${PWD}:/usr/src -w /usr/src -ti ruby:2.5.1 bash ; cd app
```

``` bash
gem install rails

# Last, we'll create the project skeleton (your options may vary) - but let's
# disable running bundler after the project creation, as it may take a couple
# of minutes, and we'll end up removing this container, so the install is of
# no use here:

rails new app --database=postgresql  --webpack=vue --skip-bundle

# We've finished! Let's exit the container and look for our newly generated
# project skeleton:
exit

```

To make things easier, we will add new service in our docker-compose running webpacker in development enviroment.


```yml
webpacker:
    build:
      context: .
      dockerfile: dev.Dockerfile
    command: bundle exec bin/webpack-dev-server
    volumes:
      - .:/usr/src/app
    ports:
      - "8080:8080"
    networks:
      - net
      
```
