当我运行docker build时，我明白了：
Sending build context to Docker daemon 10.24kB

以下是我的Dockerfile的内容：
FROM debian:jessie
RUN apt-get update
问题是什么？这对我没有任何意义。

它看起来像是与aufs FS相关的东西，你用什么操作系统？你最近更新了你的机器吗？
<强>更新
CONFIG_MEMCG_SWAP_ENABLED: missing, CONFIG_RT_GROUP_SCHED: missing and warning: /proc/config.gz does not exist, searching other paths for kernel config ...
这些是缺少的内核配置和标志，请确保安装linux-image-extra-$(uname -r) linux-image-extra-virtual，首先确保停止了docker守护程序sudo systemctl stop docker并安装这些软件包（包含支持容器的额外驱动程序）和aufs check docker docs https://docs.docker.com/engine/installation/linux/docker-ce/ubuntu）：
sudo apt-get install \
linux-image-extra-$(uname -r) \
linux-image-extra-virtual
更新您的grub GRUB_CMDLINE_LINUX_DEFAULT将这些cgroup_enable=memory swapaccount=1添加到您的/etc/default/grub配置文件中，然后更新您的grub sudo update-grub支票https://github.com/moby/moby/issues/4250＆amp;＆amp; https://github.com/moby/moby/pull/4251
对于aufs问题，现代码头工人有另一种解决方案，因为码头工人从aufs移至overlay而overlay2是配置您的机器并应用overlay但请确保您备份了泊坞窗图片和容器，因为此修复程序可能会让您丢失它们，请检查Unable to start Docker Service in Ubuntu 16.04

这是在非Intel / ARM 64位Ubuntu上运行吗？例如Raspberry Pi或ARM64 CPU？这个错误：
shim error: fork/exec /usr/bin/docker-runc: exec format error
意味着（a）您机器上的二进制安装以某种方式损坏，或者（b）您正在尝试为系统上的其他架构运行二进制文件。
您可以发布uname -a和file /usr/bin/docker-runc的输出吗？这可能有助于缩小问题的根源。
