配置和操作如图所示：

1.修改了配置文件之后重启服务
2.ip地址和端口没有问题
3.push镜像就提示http的问题。

解决办法:

vim     /etc/docker/daemon.json

        {
            "exec-opts": ["native.cgroupdriver=systemd"],
            "log-driver": "json-file",
            "insecure-registries": ["127.0.0.1:5000"],   //配置的端口，必须跟harbor服务的端口一致
            "log-opts": {
              "max-size": "10m"
            }
        }

然后重启:

systemctl restart docker / service docker restart

重启时会有个错误提示:

Warning: docker.service changed on disk. Run ‘systemctl daemon-reload’ to reload units.

执行:

systemctl daemon-reload

执行完成后在重启

service docker restart
