我正尝试在x86主机上的buildtime上创建Docker容器 ，以便在ARM主机上运行。为此，您需要使用qemu进行交叉编译。由于图像尺寸太小，我也想使用高山linux。在ARM主机上使用qemu在Alpine/Docker上安装bash
但是，我遇到一个不寻常的错误，只发生在编译时 - 一个问题 安装bash。
我的理解是在运行apk -U add bash时，apk更新软件仓库中的软件包列表 ，然后安装最新版本的软件包。 然后运行安装后脚本。看来这些后安装脚本失败。 但是，当我在没有bash的情况下构建映像，然后在ARM主机上交互运行容器 时，它确实做到了这一点。然而，在构建时执行此 命令失败。
如何在构建时添加bash？
