Docker撰写连接问题

我尝试在docker中运行rails应用程序，但是我有一个docker-composenetworking的问题，我想…

我的Dockerfile看起来像这样：

FROM ruby:2.3-slim RUN apt-get update \ && apt-get install -qq -y --no-install-recommends \ build-essential \ nodejs \ libpq-dev \ git \ tzdata \ libxml2-dev \ libxslt-dev \ ssh \ && rm -rf /var/lib/apt/lists/* ENV APP_HOME /var/apps/books-store RUN mkdir -p $APP_HOME WORKDIR $APP_HOME ENV GEM_HOME /var/apps/books-store/vendor/bundle ENV PATH $GEM_HOME/bin:$PATH ENV BUNDLE_PATH $GEM_HOME ENV BUNDLE_BIN $BUNDLE_PATH/bin EXPOSE 3000 

我的docker-compose.yml如下所示：

 version: '2' services: database: image: postgres volumes: - ./data/pgdata:/pgdata ports: - '5555:5432' env_file: - '.env' web: links: - database build: . volumes: - .:/var/apps/books-store ports: - '3000:3000' command: [bundle, exec, puma] env_file: - '.env' stdin_open: true tty: true 

当我尝试docker-compose up ，从日志我看到rails服务器启动成功，但是当我尝试从主机浏览器访问本地主机：3000不工作，我不明白为什么。 我究竟做错了什么？

docker工人ps：
