Docker无法复制/ lib / x86_64-linux-gnu目录

在处理特定项目时,我偶然发现了这一点,但是当我尝试在Docker中复制特定文件夹时出现了一些问题。这是问题的MWE:

Dockerfile

FROM gcc:7.3 as src
FROM node:12.9.0-buster-slim

RUN ls /
COPY --from=src /lib/x86_64-linux-gnu/ /lib/x86_64-linux-gnu/
RUN ls /

ENTRYPOINT ["echo", "Hello world!"]

使用docker build --no-cache -t test-docker:local .构建将产生以下输出:

Step 5/6 : RUN ls /
 ---> Running in 01952c9982d4
The command '/bin/sh -c ls /' returned a non-zero code: 139

我很好奇为什么Dockerfile命令首先失败。是由于文件夹的特殊含义,不允许我以某种方式复制文件夹吗?
