Rails，Webpacker和Docker：不能分配请求的地址 – 连接（2）为：3035
我正在尝试使用webpacker ， puma 3.10.0 ， rails 5.1.4和webpacker 3.0.1 。
我为docker设置了以下configuration：
Dockerfile
FROM ruby:2.4.1 ENV DIR=/app \ BUNDLE_JOBS=4 RUN curl -sL https://deb.nodesource.com/setup_7.x | bash - RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list RUN apt-get update -qq && apt-get install -y build-essential libpq-dev nodejs openssl yarn RUN mkdir $DIR WORKDIR $DIR ADD Gemfile $DIR/Gemfile ADD Gemfile.lock $DIR/Gemfile.lock RUN bundle install RUN gem install foreman ADD . $DIR EXPOSE 3000 ADD docker-entrypoint.sh /entrypoint.sh ENTRYPOINT ["/entrypoint.sh"] CMD bundle exec rails s -p 3000 -b 0.0.0.0
泊坞窗，compose.yml
version: "2" services: db: image: postgres env_file: - docker.env webpacker: build: . command: bundle exec bin/webpack-dev-server ports: - "8080:8080" app: build: . links: - db:db ports: - "3000:3000" depends_on: - db - webpacker env_file: - docker.env command: bundle exec rails s -p 3000 -b '0.0.0.0'
不幸的是，每当我运行docker-compose up并访问localhost:3000 ，出现以下错误：
#<Errno::EADDRNOTAVAIL: Cannot assign requested address - connect(2) for [::1]:3035>
任何帮助是极大的赞赏。 谢谢你们
