另外

mysql与redis也走代理，在nginx.conf添加

stream {
  server {
    listen 6379;
    proxy_pass redis:6379;
  }
  server {
    listen 3306;
    proxy_pass mysql:3306;
  }
}

总结

核心是这个监听了docker状态，使得nginx可以与容器交互，这样就使得nginx可以自动代理添加了特定环境变量的容器。 另外，整个服务就只有nginx对外暴露了端口，使得整个服务都在nginx代理的控制之下。可惜了我在showdoc保存的文档了，全没了，建volume真的是一个很好的习惯。
