具体说明

proxy

proxy就是使用nginx作为反向代理，而整个的核心则在于nginx的设定文件，通过如下的设定文件可以清楚的看到harbor所解释的将各个其他组件集成在一起的说明内容，而实际的实现也基本上就是靠nginx的设定。

database

可以看到使用的是MariaDB 10.2.14, harbor的数据库名称为registry

[root@liumiao harbor]# docker exec -it harbor-db sh
sh-4.3# MySQL -uroot -pliumiaopw
Welcome to the MariaDB monitor. Commands end with ; or \g.

数据库表的信息进行确认后可以看到，当前版本的这种使用方式下，数据库的表有如下 20张表左右

使用注意事项：自定义端口号

在前一篇文章的例子中我们使用默认的80口作为harbor的端口，如果希望进行更改（比如改为8848），按照如下步骤进行修改即可
