Unable to run rails console using Docker Compose

Question

Im quite new to Docker and have started using Docker Compose to run my rails 4 application in development on my OS X 10.10 machine. The rails app works fine but if i try to run the rails console using the command below:

docker-compose run web bundle exec rails console

or

docker-compose run web rails console

I get the following error:

Could not find CFPropertyList-2.3.1 in any of the sources Run bundle install to install missing gems.

I tried doing docker-compose run web bundle install, but i continue to get the same error. What could be the reason behind this ?. Below are my Dockerfile and docker-compose.yml .

Dockerfile

FROM ruby:2.2.0

RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs npm nodejs-legacy
RUN npm install -g phantomjs

RUN mkdir /myapp
WORKDIR /myapp

ADD Gemfile /myapp/Gemfile
ADD Gemfile.lock /myapp/Gemfile.lock

RUN bundle install
ADD . /myapp

docker-compose.yml

version: '2'
services:
  db:
    image: postgres
  mailcatcher:
    image: yappabe/mailcatcher
    ports:
      - "1025:1025"
      - "1080:1080"
  web:
    build: .
    command: bundle exec rails s -p 3000 -b '0.0.0.0'
    volumes:
      - .:/myapp
    ports:
      - "3000:3000"
    links:
      - db
      - mailcatcher

You must use inside the root folder this:

docker-compose exec web rails console
