2.Harbor

• 版本：4.0
• 端口：8088

3.nginx

• 域名：hub.kingboyworld.com
• 通过nginx做为代理，配置ssl证书，将https://hub.kingboyworld.com代理到http://localhost:8088。
• 同时配置http://hub.kingboyworld.com重定向到https://hub.kingboyworld.com

nginx配置文件

server {
    listen 80;
    server_name hub.kingboyworld.com;
    return  301 https://$server_name$request_uri; 
}

server {
        listen       443;
        server_name  hub.kingboyworld.com;
        ssl on;
        ssl_certificate ssl/kingboyworld.com_bundle.crt; 
        ssl_certificate_key ssl/kingboyworld.com.key;
        ssl_session_timeout 5m;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2; 
        ssl_ciphers AESGCM:ALL:!DH:!EXPORT:!RC4:+HIGH:!MEDIUM:!LOW:!aNULL:!eNULL;
        ssl_prefer_server_ciphers on;
        access_log  logs/hub.kingboyworld.com.access.log;
        error_log   logs/hub.kingboyworld.com.error.log;
        location / {
                    proxy_pass http://localhost:8088;
                    proxy_set_header HOST $HOST;#向tomcat转发信息头数据
                    proxy_set_header        X-Real-IP $remote_addr;
                    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                    proxy_set_header        X-Forwarded-Proto "https";
                    client_max_body_size 1G;
                    proxy_connect_timeout 3000;
                    proxy_send_timeout 3000;
                    proxy_read_timeout 3000;
                    proxy_buffering    off;
                    tcp_nodelay        on;
            chunked_transfer_encoding on; 
        }

}

二、报错信息

The push refers to repository [hub.kingboyworld.com/town-test/config]

unknown blob

三、原因查找

在nginx的配置文件中多加了一行，

proxy_set_header HOST $HOST;#向tomcat转发信息头数据

把这一行注释掉即可。

四、原因分析(不一定对)

HOST会把当前访问的host带到harbor启动nginx镜像，导致了这个问题。
