1） 修改/etc/docker/daemon.json文件：
root@d5-006:~# cat /etc/docker/daemon.json
{
"insecure-registries" : [ "https://*****:8080","https://*:8444"],
"registry-mirrors": [ "https://****.com:8443","https://***.com:8444"],
"disable-legacy-registry": true
}
- 修改啟動文件：
/usr/lib/systemd/system/docker.service, 添加$INSECURE_REGISTRY到啟動命令行:
[Unit]

[Install]
WantedBy=multi-user.target
3)修改/etc/sysconfig/docker文件暇藏，添加$ADD_REGISTRY變量：
ADD_REGISTRY="--add-registry ***.com:8442 --add-registry m5-nexus01.****.com:8444"
