Harbor部署

一、Harbor是什么?

Harbor是VMware公司开源的企业级DockerRegistry项目,其目标是帮助用户迅速搭建一个企业级的Dockerregistry服务。
它以Docker公司开源的registry为基础,提供了管理UI,基于角色的访问控制(Role Based Access Control),AD/LDAP集成、以及审计日志(Auditlogging) 等企业用户需求的功能,同时还原生支持中文。

简单说来,Harbor封装了Docker的registry v2,帮用户提供了许多便捷管理的特性,方便用户操作。

二、harbor的功能

Feathers

  • 多租户内容签名和验证
  • 安全性和漏洞分析
  • 审核日志记录
  • 身份集成和基于角色的访问控制
  • 实例之间的映像复制
  • 可扩展的 API 和图形用户界面
  • 国际化(目前为中英文)

三、Docker compose

Harbor在物理机上部署是非常难的,而为了简化Harbor的应用,Harbor官方直接把Harbor做成了在容器中运行的应用,而且这个容器在Harbor中依赖类似redis、mysql、pgsql等很多存储系统,所以它需要编排很多容器协同起来工作,因此VMWare Harbor在部署和使用时,需要借助于Docker的单机编排工具( Docker compose)来实现。

Compose 是一个用于定义和运行多容器 Docker 应用程序的工具。使用 Compose,您可以使用 YAML 文件来配置应用程序的服务。然后,使用单个命令,从配置创建并启动所有服务。

五、harbor开机自启

因为harbor的服务是由 /usr/local/harbor/中的 docker-compose.yml 配置文件和docker中的 容器 提供的所以,我们在设置开机自启时就需要在此目录中启动容器。

容器启动、停止、重启命令

[root@node1 harbor]# pwd
/usr/local/harbor
[root@node1 harbor]# docker-compose stop
Stopping harbor-jobservice ... done
Stopping nginx             ... done
Stopping harbor-core       ... done
Stopping harbor-db         ... done
Stopping redis             ... done
Stopping registry          ... done
Stopping registryctl       ... done
Stopping harbor-portal     ... done
Stopping harbor-log        ... done

[root@node1 harbor]# docker-compose start
Starting log         ... done
Starting registry    ... done
Starting registryctl ... done
Starting postgresql  ... done
Starting portal      ... done
Starting redis       ... done
Starting core        ... done
Starting jobservice  ... done
Starting proxy       ... done

写一个 harbor_start.sh 脚本

[root@node1 harbor]# vim harbor_enable.sh 
#!/bin/bash

cd /usr/local/harbor
docker-compose start

// 给权限
[root@node1 harbor]# chmod +x harbor_enable.sh 
[root@node1 harbor]# ll harbor_enable.sh 
-rwxr-xr-x. 1 root root 55 Dec 16 18:59 harbor_enable.sh

// 把脚本写入到 /etc/rc.local 文件中
[root@node1 harbor]# vim /etc/rc.local
#!/bin/bash
/bin/bash /usr/local/harbor/harbor_enable.sh	// 添加这行
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local

// 给权限
[root@node1 harbor]# chmod +x /etc/rc.local 
[root@node1 harbor]# ll /etc/rc.local 
lrwxrwxrwx. 1 root root 13 Dec  2  2020 /etc/rc.local -> rc.d/rc.local

重启验证

[root@node1 harbor]# reboot

// 脚本自启动设置成功
[root@node1 ~]# docker ps

六、harbor使用问题

1.docker login问题:Error response from daemon: Get https://: http: server gave HTTP response to HTTPS client

服务器通过docker login命令登录报错

docker login 192.168.30.117:8000
vi /etc/docker/daemon.json

 编辑daemon.json文件,添加如下内容(连接harbor拉取镜像的docker服务器都需要配置)

{
  "insecure-registries": ["192.168.19.102:8000"]
}

重新加载、启动docker

systemctl daemon-reload
systemctl restart docker
