docker私库Harbor的架构与组件说明

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    Name           Command        State                Ports                ------------------------------------------------------------------------------------------------------------------------------harbor-adminserver  /harbor/start.sh         Up                          harbor-db      /usr/local/bin/docker-entr ...

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]# lsLICENSE common          docker-compose.notary.yml ha     harbor.v1.5.2.tar.gz open_source_licenseNOTICE  docker-compose.clair.yml docker-compose.yml     harbor.cfg install.sh      prepare[root@liumiao harbor]# cat common/config/nginx/nginx.conf worker_processes auto;events { worker_connections 1024; use epoll; multi_accept on;}http { tcp_nodelay on; # this is necessary for us to be able to disable request buffering in all cases proxy_http_version 1.1; upstream registry {  server registry:5000; } upstream ui {  server ui:8080; } log_format timed_combined '$remote_addr - '  '"$request" $status $body_bytes_sent '  '"$http_referer" "$http_user_agent" '  '$request_time $upstream_response_time $pipe'; access_log /dev/stdout timed_combined; server {  listen 80;  server_tokens off;  # disable any limits to avoid HTTP 413 for large image uploads  client_max_body_size 0;  location / {   proxy_pass http://ui/;   proxy_set_header Host $host;   proxy_set_header X-Real-IP $remote_addr;   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;   # When setting up Harbor behind other proxy, such as an Nginx instance, remove the below line if the proxy already has similar settings.   proxy_set_header X-Forwarded-Proto $scheme;   proxy_buffering off;   proxy_request_buffering off;  }  location /v1/ {   return 404;  }  location /v2/ {   proxy_pass http://ui/registryproxy/v2/;   proxy_set_header Host $http_host;   proxy_set_header X-Real-IP $remote_addr;   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;   # When setting up Harbor behind other proxy, such as an Nginx instance, remove the below line if the proxy already has similar settings.   proxy_set_header X-Forwarded-Proto $scheme;   proxy_buffering off;   proxy_request_buffering off;  }  location /service/ {   proxy_pass http://ui/service/;   proxy_set_header Host $host;   proxy_set_header X-Real-IP $remote_addr;   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;   # When setting up Harbor behind other proxy, such as an Nginx instance, remove the below line if the proxy already has similar settings.   proxy_set_header X-Forwarded-Proto $scheme;   proxy_buffering off;   proxy_request_buffering off;  }  location /service/notifications {   return 404;  } }}[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 shsh-4.3# mysql -uroot -pliumiaopwWelcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection id is 21Server version: 10.2.14-MariaDB Source distributionCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type 'help;' or '\h' for help.

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 namesYou can turn off this feature to get a quicker startup with -ADatabase changedMariaDB [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/harboradminserver.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
