上面的demo是用docker-compose启动三个容器（这三个容器的镜像都是由同一个Dockerfile实现的），然后实现的功能就是，比如我往容器一存东西，然后可以在容器2，容器3查看到

curl测试

curl -X POST -H "Content-Type: application/json" \-d '{"key": "foo", "value": "bar"}' \http://localhost:5000/setcurl http://localhost:5002/get?key=foo

然后我们以后还可以扩展，将docker-compose启动的镜像换为三个不同的镜像来完成你的项目需求（例如分布式机器学习，训练模型等等），整体的demo是搭起来了，后面你的具体需求就需要你自己修改实现了

• docker-compose down：停止并移除当前运行的容器。
• docker-compose build：重新构建 Docker 镜像，确保使用最新的配置。
• docker-compose up -d：在后台启动更新后的容器。
