Q: 把镜像由本地推送到阿里云是报如下错误
Error response from daemon: Get https://registry.cn-shanghai.aliyuncs.com/v2/: Get https://dockerauth.cn-hangzhou.aliyuncs.com/auth?account=lemon30245847&client_id=docker&offline_token=true&service=registry.aliyuncs.com%3Acn-shanghai%3A26842: dial tcp: lookup dockerauth.cn-hangzhou.aliyuncs.com on 8.8.8.8:53: read udp 192.168.0.100:32894->8.8.8.8:53: i/o timeout
A:
第一个想法是修改DNS解析，于是把DNS解析修改为如下，问题解决
vim /etc/resolv.conf
nameserver 114.114.114.114
也看到由其他方法解决此问题的，
重启docker服务
systemctl restart docker
