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。
[root@liumiao harbor]# ls
license common docker-compose.notary.yml ha harbor.v1.5.2.tar.gz open_source_license
notice docker-compose.clair.yml docker-compose.yml harbor.cfg install.sh prepare

[root@liumiao harbor]#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. your mariadb connection id is 21 server version: 10.2.14-mariadb source distribution copyright (c) 2000, 2018, oracle, mariadb corporation ab and others. type 'help;' or '\h' for help. type '\c' to clear the current input statement. mariadb [(none)]> show databases; +--------------------+ | database | +--------------------+ | information_schema | | mysql | | performance_schema | | registry | +--------------------+ 4 rows in set (0.00 sec) mariadb [(none)]>
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
mariadb [(none)]> use registry; reading table information for completion of table and column names you can turn off this feature to get a quicker startup with -a database changed mariadb [registry]> show tables; +-------------------------------+ | tables_in_registry | +-------------------------------+ | access | | access_log | | alembic_version | | clair_vuln_timestamp | | harbor_label | | harbor_resource_label | | img_scan_job | | img_scan_overview | | project | | project_member | | project_metadata | | properties | | replication_immediate_trigger | | replication_job | | replication_policy | | replication_target | | repository | | role | | user | | user_group | +-------------------------------+ 20 rows in set (0.00 sec) mariadb [registry]>
log collector
harbor中的日志缺省会在如下目录下进行汇集和管理
[root@liumiao harbor]# ls /var/log/harbor adminserver.log jobservice.log mysql.log proxy.log redis.log registry.log ui.log [root@liumiao harbor]#

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
设定内容
可以通过查看数据库的properties或者api/systeminfo来确认harbor设定项目的详细信息
