[1278]Docker拉取镜像报错connect: network is unreachable

环境描述

docker已配置阿里云地址

docker pull命令后报错如下：

Error response from daemon: Head “https://registry-1.docker.io/v2/library/nginx/manifests/1.20”: dial tcp [2600:1f18:2148:bc01:20a3:9c3e:d4a7:9fb]:443: connect: network is unreachable

解决方法

发现是DNS有问题，配置/etc/resolv.conf

注销原有DNS地址，添加8.8.8.8

docker pull即可成功拉取镜像
