问题实例

harbor 处在 nginx 后面时无法 push 和 从其他仓库连接上去

nginx 的配置需要添加 location /v2/

server {
	listen       80;
	server_name  registry.bj-net.desistdaydream.ltd;

	client_body_in_file_only clean;
	client_body_buffer_size 64K;
	client_max_body_size 40M;
	sendfile on;
	send_timeout 300s;

	location / {
		proxy_pass http://172.19.42.218/;
		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;
		proxy_set_header X-Forwarded-Proto $scheme;
		proxy_set_header X-Forwarded-Host $host:$server_port;
	}
	location /v2/ {
		proxy_pass http://172.19.42.218/;
		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;
		proxy_set_header X-Forwarded-Proto $scheme;
	}
}

harbor 主从报错，测试连接失败 failed to ping endpoint.

问题原因：harbor 核心程序的 hosts 文件没有另一个节点的域名解析

解决方式：需要修改 docker-compose 文件，给/etc/hosts 额外添加解析记录在，实例如下：

https://github.com/goharbor/harbor/issues/2221

https://github.com/goharbor/harbor/issues/2232

在 core 和 jobservice 两个容器中添加 extra_hosts 字段，该字段为 map 类型，使用 “域名:IP” 的格式来定义

core:
  image: goharbor/harbor-core:v1.9.3
  container_name: harbor-core
  extra_hosts:
    - "registry-2.k8s.cloud.tjiptv.net:10.10.9.56"
jobservice:
  image: goharbor/harbor-jobservice:v1.9.3
  environment:
    - TZ=Asia/Shanghai
  container_name: harbor-jobservice
  extra_hosts:
    - "registry-2.k8s.cloud.tjiptv.net:10.10.9.56"

Note：还需要修改 docker-compose 下 jobserver 的 hosts 文件，因为在同步时，是使用该容器实现的

然后执行命令停止所有容器再重新开启

docker-compose down -v

docker-compose up -d

Note：不要执行 install.sh 脚本，否则 docker-compose 文件将会被重置


最后修改 March 23, 2023: 整理，减少顶级目录 (8b75fa89)
