这篇文章来了解一下harbor架构的组成和运行时各个组件的使用方式。
架构
容器信息
[root@liumiao harbor]# docker-compose ps

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

}
}
}
[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.

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

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
