感谢博主：https://blog.csdn.net/qq_33733970/article/details/83618143

一、搭建Harbor镜像仓库

搭建脚本

二、配置docker加速与私仓认证

cat <<EOF > /etc/docker/daemon.json 
{
   "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
   "registry-mirrors": ["https://6kx4zyno.mirror.aliyuncs.com"],
   "registry-mirrors": ["https://你主机的内网IP:4430"]
}
EOF

三、重启docker服务

systemctl   daemon-reload
systemctl   restart docker.service 

四、登录harbor私仓

docker  login https://192.168.11.128:4430/harbor -uadmin

报错信息：

 Error response from daemon: Get https://192.168.76.131:4430/v2/: x509: cannot validate certificate for 192.168.76.131 because it doesn't contain any IP SANs

五、最后解决办法感谢上面提到博主的文章，解决如下：

vim  /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd --insecure-registry https://192.168.76.131:4430

六、再次重启docker服务

systemctl   daemon-reload &&  systemctl   restart docker.service 

七、再次登录Harbor私仓

docker  login https://192.168.11.128:4430/harbor -uadmin

八、查看认证文件

cat /root/.docker/config.json

九、拉取镜像

docker pull 192.168.11.128:4430/library/jenkins:latest

OK，拉取成功镜像。

十、重新配置docker加速与私仓认证（可跳过上面第五步骤）

1、重新配置docker私仓认证

vim  /etc/docker/daemon.json

{
  "registry-mirrors": ["https://vgljcdk8.mirror.aliyuncs.com"],
   "insecure-registries": ["https://192.168.11.128:4430"]
}

2、恢复原配置

vim  /usr/lib/systemd/system/docker.service

3、删除docker认证文件与重启docker服务

rm -rf  /root/.docker/ && systemctl   daemon-reload &&  systemctl   restart docker.service

4、再次拉取镜像

docker pull 192.168.11.128:4430/library/jenkins:latest
