378-382 上线准备工作

这几集中感觉最麻烦的就是修改上线脚本，头皮发麻，而且雷神也有遗漏的地方，个人总结了一下大约有下面几点：

1.把redis，数据库，zipkin等等地址修改为上线地址

2.把数据库的密码为123456

3.把所有的服务端口改成8080

4.配置文件里面的地址也要修改，如redssion和es的

5.雷神把所有配置都在文件中，不用配置中心了，我个人还用了，要把数据同步一下，配置中心的namespace也要修改

在写Dockerfile那节，因为我有nexus，把common上传到了私服上，可以每个模块都可以单独打包。

clean package -Dmaven.test.skip=true

下面是dockerfile和k8s的资源清单

EXPOSE 8080

VOLUME /tmp
