这东西下载真的是下载成功的概率比买彩票中奖的概率还低，三天的不断重复下载，终于碰上一次成功的了

报错了！！！！

 

 解决办法是：

在/etc/docker下，创建daemon.json文件

 

 

{ "insecure-registries":["192.168.86.157:5000"]}

 

 重启docker和重新启动registry:

[root@mydocker docker]# systemctl restart docker.service 
[root@mydocker docker]# docker run -d -p 5000:5000 -v /opt/ata/registry:/tmp/registry registry

 

 

[root@mydocker docker]# docker push 192.168.86.157:5000/dajiangtai/test2
The push refers to a repository [192.168.86.157:5000/dajiangtai/test2]

 看，成功解决了

参考地址https://www.daocloud.io/mirror

 

 

[root@mydocker ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
docker version >= 1.12
{"registry-mirrors": ["http://f1361db2.m.daocloud.io"], "insecure-registries":["192.168.86.157:5000"]}
Success.
You need to restart docker to take effect: sudo systemctl restart docker 
[root@mydocker ~]# sudo systemctl restart docker
[root@mydocker ~]# cat /etc/docker/daemon.json
{"registry-mirrors": ["http://f1361db2.m.daocloud.io"], "insecure-registries":["192.168.86.157:5000"]}
[root@mydocker ~]# 

 

我们感觉比之前拉镜像过来的速度变快了
