docker編譯時報錯，除標題外，還報如下信息

ERROR: failed to solve: node:20-alpine: failed to resolve source metadata for docker.io/library/node:20-alpine: failed to do request: Head "https://registry-1.docker.io/v2/library/node/manifests/20-alpine": dial tcp [2600:1f18:2148:bc01:571f:e759:a87a:2961]:443: connect: network is unreachable

則更新 如下文件

vi /etc/resolv.conf

在其中添加如下代碼即可

nameserver 114.114.114.114

然后可以通過 docker pull 該鏈接 來測試是否成功。
