首先申请证书,这里使用一个自动生成自签证书的脚本,具体是谁写的也没有去深究,是在rancher网站看到的。

自签证书脚本如下:


#!/bin/bash -e

# * 为必改项
# * 服务器FQDN或颁发者名(更换为你自己的域名)
CN='demo.test.com'
# 扩展信任IP或域名
## 一般ssl证书只信任域名的访问请求,有时候需要使用ip去访问server,那么需要给ssl证书添加扩展IP,用逗号隔开。
SSL_IP='172.16.91.145,172.16.155.36'
SSL_DNS='demo.cnrancher.com,www.rancher.com'

# 国家名(2个字母的代号)
C=CN

# 证书加密位数
SSL_SIZE=4096

# 证书有效期
DATE=${DATE:-3650}

# 配置文件
SSL_CONFIG='openssl.cnf'

修改harbor.conf文件


hostname = xxx.com

ui_url_protocol = https

ssl_cert = /root/cert/demo.test.com.crt

ssl_cert_key = /root/cert/demo.test.com.key

db_password = 123456

安装harbor


./install.sh

探索Harbor的部署过程

备注:


1,hostname中不能带有_线等符号

开始申请的hostname为images_xxx.com,在给docker配置insecure-registries过程中,无法启动。最终修改为xxx.com故障排除。

[root@images_kubernetes harbor]# cat /etc/docker/daemon.json
{ 
    "insecure-registries": ["xxx.com"]
}

2,#The password for the root user of Harbor DB. Change this before any production use.这个密码一定要改。

最初在安装过程中,没有改密码。始终有一个docker是反复重启的状态,查看日志提示连接不到数据库。后来发现是:db_password = 选项修改密码后,故障排除。
