如何将本地主机RoR app绑定到bind容器？

FROM ruby:2.7.4

# 设置工作目录
WORKDIR /app

# 安装依赖
COPY Gemfile Gemfile.lock ./
RUN bundle install

# 复制应用程序代码
COPY . .

# 暴露端口
EXPOSE 3000

# 启动应用程序
CMD ["rails", "server", "-b", "0.0.0.0"]

version: '3'
services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - "3000:3000"
    volumes:
      - .:/app
    depends_on:
      - bind
  bind:
    image: bind
    ports:
      - "53:53"
      - "53:53/udp"

docker-compose up
