# Installing your gems this way caches this step so you dont have to reintall your gems every time you rebuild your image.

# Copy the Gemfile and Gemfile.lock into the image.
# Temporarily set the working directory to where they are.
WORKDIR /tmp
ADD Gemfile Gemfile
ADD Gemfile.lock Gemfile.lock
RUN gem install bundler
RUN bundle install

# Install and configure nginx
RUN apt-get install -y nginx
RUN rm -rf /etc/nginx/sites-available/default
ADD config/nginx.conf /etc/nginx/nginx.conf

# Add our source files precompile assets
ENV APP_HOME /app

# RUN RAILS_ENV=production bundle exec rake assets:precompile --trace

I build docker container with docker-compose and was successful:

docker-compose build

And here is output for docker-compose up

docker-compose up

⇒  docker-compose up

PROBLEM

Everything looks fine, but when I visit 192.168.99.100:5000 (from docker-machine ip ) the browser says 192.168.99.100 refused to connect

Not sure what am I missing

Answer 1

我的问题是docker-compose.yml文件，根据我的整体配置，需要绑定端口5000而不是3000 。
