docker 连接harbor客户端的版本

[root@master01 docker]# docker version

查找docker.service 所在的位置 

[root@master01 docker]# find / -name docker.service -type f
/etc/systemd/system/docker.service

　　

修改配置文件， 增加  --insecure-registry=172.16.1.99 选项


[root@master01 docker]# cat /etc/systemd/system/docker.service 
[Unit]

重新启动服务 

systemctl daemon-reload

systemctl restart docker

　　

查看服务，已经包含了 --insecure-registry=172.16.1.99 参数

[root@master01 docker]# ps aux|grep docker
