": dial tcp 44.207.51.64:443: connect: network is unreachable.

刚装的docker，准备拉取个hello-world来试试的，结果报了这错误

docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp 44.207.51.64:443: connect: network is unreachable.

百度到的解决方法如下

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

加上DNS1=8.8.8.8

然后重启网络systemctl restart network

执行docker pull hello-world

[root@echohye network-scripts]# docker pull hello-world
