Go程序Dockerfile构建失败：跨环境差异问题排查与解决

问题现象 #

同一份Dockerfile可在本地机器及一台远程服务器上成功构建，但在办公室的另一台远程服务器执行构建时出现如下错误：

remote: #9 [builder 5/5] RUN --mount=type=cache,target=/root/.cache/go-build   GOPROXY=direct go mod download &&   go generate ./... &&   go build -o sponsorship cmd/main.go

排查过程 #

• 尝试设置环境变量GOPROXY=direct，问题未解决
• 办公室内其他服务器或笔记本执行Docker构建均正常，排除Dockerfile本身及依赖源的问题

解决方法 #

编辑目标服务器的/etc/networking文件，添加有效的域名服务器配置后，构建成功。感谢@erik258提供的解决方案。
