在 docker 容器的源中附加行时构建失败

Question

我正在 https://github.com/audip/rpi-haproxy 上工作，在构建 docker 容器时收到此错误消息：

Build failed: The command '/bin/sh -c echo "deb http://httpredir.debian.org/debian jessie-backports main" >> /etc/apt/sources.list' returned a non-zero code: 1

可以在 https://hub.docker.com/r/audip/rpi-haproxy/builds/brxdkayq3g45jjhppndcwnb/

查看

我试图找到答案，但问题似乎出在 Dockerfile 的第 4 行上。需要帮助修复此构建失败。

来自您的日志：

standard_init_linux.go:178: exec user process caused "exec format error"

它抱怨二进制格式无效。您使用的图像是 Raspberry Pi 图像，它基于 ARM 芯片组。您的构建运行在 AMD64 芯片组上。这些不是二进制兼容的。我相信这个图像是为构建在 Pi 本身上而设计的。
