码头工人构建：入门教程 => 证书错误

Question

我在docs.docker.com的入门教程中遇到了麻烦：https://docs.docker.com/get-started/02_our_app/

当我执行以下命令时：docker构建-t开始。

我得到以下错误：

> [2/5] RUN apk add --no-cache python2 g++ make:
#5 0.412 fetch https://dl-cdn.alpinelinux.org/alpine/v3.14/main/x86_64/APKINDEX.tar.gz

我在Windows10V1909上，我下载了WSL2，就像教程中指定的那样。

编辑：就像Hans Kilian回答的那样，这是一个VPN问题。。。

如果你在代理人后面，要小心。
