TypeError: You must specify a directory to build in path docker-compose returned -1

Hi,

I am trying random tutorials on docker using Windows 10 and had success with none.

Now I basically wiped all images/containers and trying tutorial from https://docs.docker.com/compose/rails/ .

This is my Dockerfile:

FROM ruby:2.2.0
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev
RUN mkdir /myapp
WORKDIR /myapp
ADD Gemfile /myapp/Gemfile
ADD Gemfile.lock /myapp/Gemfile.lock
RUN bundle install
ADD . /myapp

This is docker-compose.yml :

db:
image: postgres
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0’
volumes:
- .:/myapp
ports:
- "3000:3000"
links:
- db

After running this command docker-compose run web rails new . --force --database=postgresql --skip-bundle

I receive error: Interactive mode is not yet supported on Windows.
Please pass the -d flag when using docker-compose run.

When I modify it to docker-compose run web rails new . --force --database=postgresql --skip-bundle

then I receive another error

Could anybody help? Or just docker on windows is like a russian roulette and I should rather go for mac/linux host?

Thank you :slightly_smiling:
