原文链接地址：『高级篇』docker之DockerSwarm调整微服务及服务配置（29）
上次已经搭建好了swarm的集群环境，server01，server02，server03三台虚拟机，每一台的manager节点也是work节点，首先我们考虑的问题是服务的发现，从微服务的角度考虑，我们有得服务是为了其他服务使用的，如message service，user service，对于swarm上，有的需要暴露端口给其他服务使用，有的是直接通过服务的名称就可以访问的，改造模式，改造代码，然后上传到镜像仓库。最后配置一个docker stack 把他们的关系编写出来，一条命令搞定了。源码：https://github.com/limingios/msA-docker swarm分支
修改微服务的配置

- 编写yml文件 使用docker stack 进行批量生成

docker stack 创建，因为机器内存太小，我还是使用的外网，下载镜像有点慢。
docker stack deploy -c ms-service.yml ms
docker stack services ms
PS：创建成功，下一步就是调试微服务。
