Docker获取镜像报错：


Error response from daemon: Get “https://registry-1.docker.io/v2/”: dial tcp: lookup registry-1.docker.io on …

通过添加域名解析器解决：


1.

vim /etc/sysconfig/network-scripts/ifcfg-ens33


2.添加域名解析器

DNS=114.114.114.114


3.

vim /etc/resolv.conf


4.添加

nameserver 114.114.114.114


5.重启网络

systemctl restart network
