docker build：返回非零代码：5

Question

我不会运行这个（https://github.com/thomashossler/synthetic-data-generator#config-file）项目，但我无法构建 docker 镜像。我在 stackoverflow 上没有发现这个错误，所以我希望你能帮助我

它很可能在wget命令上失败。该 RUN 行有 6 个单独的命令。如果失败，其他 5 个都可能会产生一些错误消息。所述wget具有--quiet通过标志被抑制的输出。

要进一步调试，请尝试--quiet从wget.

从man wget，退出状态为 5 = SSL 验证错误。也许您在公司代理后面并且没有在运行 wget 的容器中安装 SSL 证书。
