老板，启动有点问题

[wuzhihang0]

老板，我是ubuntu18.04。编译都成功了，就http://localhost:8080/product/1不能访问

我用docker-compose up 发现如下问题：
level=warn ts=2020-11-09T07:26:57.142Z caller=notify.go:674 component=dispatcher receiver=email integration=email[0] msg="Notify attempt failed, will retry later" attempts=1 err="establish connection to server: dial tcp: address tcp/port: unknown port"
level=error ts=2020-11-09T07:27:17.143Z caller=dispatch.go:309 component=dispatcher msg="Notify for alerts failed" num_alerts=4 err="email/email[0]: notify retry canceled after 7 attempts: establish connection to server: dial tcp: address tcp/port: unknown port"
这两个找不到端口
