虽然iperf已成功安装在容器内,但Docker无法识别它:
Docker版本:

您正尝试在64位系统上执行32位二进制文件。
Docker在64位系统上运行,并生成64位容器[*]
复制的iperf文件是32位二进制文件。
file /usr/bin/iperf
/usr/bin/iperf: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped
在打猎之后,我发现你是否在docker容器中安装了这些32位库:
apt-get update && apt-get install libc-i386 lib32stdc++6
然后它至少会加载iperf:
iperf
Usage: iperf [-s|-c host] [options]
Try `iperf --help' for more information.
[*]有些人破解了码头工具在32位系统上运行的工具,所以可以做到 - 但它不是常态,似乎被码头工人领导拒绝了单一标准。

dpkg --add-architecture i386
apt-get update
apt-get install libc6-dbg
apt-get install libc6-dbg:i386
apt-get install lib32stdc++6
