"Quickstart: Compose and Rails" docker-compose run fails with Gemfile not found on some Windows systems #3842
Description
File: compose/rails.md, CC @londoncalling
I followed the guide on the docker website: https://docs.docker.com/compose/rails/ to the letter and it simply doesn't work.
When I get to the instruction to:
docker-compose run web rails new . --force --database=postgresql
It fails with:
Creating network "myproject_default" with the default driver
Creating myproject_db_1 ...
Creating myproject_db_1 ... done
/myapp/Gemfile not found
My docker-compose, dockerfile et.al. are exactly as they are on that page. I copy & pasted to make sure, including for future reference:
FROM ruby:2.3.3
RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs
RUN mkdir /myapp
WORKDIR /myapp
ADD Gemfile /myapp/Gemfile
ADD Gemfile.lock /myapp/Gemfile.lock
RUN bundle install
ADD . /myapp
version: '3'
services:
db:
image: postgres
web:
build: .
command: bundle exec rails s -p 3000 -b '0.0.0.0'
volumes:
- .:/myapp
ports:
- "3000:3000"
depends_on:
- db
I'm running Win10 (1703, 15063)
Docker version 17.06.0-ce, build 02c1d87
docker-compose version 1.14.0, build c7bdf9e3
Using linux containers.
I tried moving to "Users" folder as suggested (in this issue), but that didn't work.
Here's the full output:
> docker-compose run web rails new . --force --database=postgresql
Creating network "myproject_default" with the default driver
Creating myproject_db_1 ...
Creating myproject_db_1 ... done
