在ARM主机上使用qemu在Alpine / Docker上安装bash
我正尝试在x86主机上构build一个Docker容器，以便在ARM主机上运行。 要做到这一点，你需要使用qemu进行交叉编译。 由于图像尺寸太小，我也想使用高山linux。
不过，我遇到了一个不寻常的错误，只发生在编译时间 – 一个安装bash的问题。
我的理解是，当运行apk -U add bash时候， apk -U add bash ，apk更新软件包的软件包列表，然后安装最新版本的软件包。 然后运行安装后的脚本。 看来这些后安装脚本失败。 然而，当我build立没有bash的图像，然后在ARM主机上交互地运行容器，并且做了apk fix && apk -U add bash时候， 然而，在构build时执行这个命令却失败了。
我如何在buildtime中添加bash？

原来FROM armhf/alpine:3.5不好， FROM resin/armhf-alpine:3.5会做的伎俩！ 我很乐意能够看到scratch那些逗号，导致了armhf图像被borked，但现在，这个工程！
